Frequently Asked Questions
What’s the difference between R-22 and R-410 refrigerants?
Refrigerants are liquids that are contained within your air conditioner’s coils. They are what makes your air conditioner able to cool and dehumidify the air indoors. Air conditioners use two different types of refrigerant: R-22 and R-410. For a long time, the R-22 refrigerant (often referred to by the brand name Freon) was the most common kind of refrigerant, but it’s starting to be phased out due to ozone depletion concerns. The R-410 refrigerant (often referred to by the brand name Freon) is chlorine-free, which is considered ozone-friendly.
As of Jan 1, 2020, manufacturers can no longer produce R-22 refrigerant and Jan 2015 manufacturers were no longer allowed to produce units that use it. Since 2015, R-410 refrigerant has become the new standard. Since R-410 can absorb and release more heat than R-22 refrigerant, your air conditioning compressor can run cooler, which reduces the risk of compressor burnout due to overheating.
What is two-stage cooling?
Two-stage cooling refers to the type of compressor in an air conditioner or heat pump. A two-stage cooling compressor has two separate levels that it operates at depending on your cooling needs. On hot days it will run at full capacity; during milder temperatures, it will run at partial capacity. Most of the time, the low setting is adequate.
Two-stage units are more energy-efficient, as they run for longer periods. For example, on a hot day, your unit may use full-capacity to reach your desired temperature; afterward, it will use part-capacity to maintain the temperature for as long as possible. Two-stage units produce more even temperatures throughout the home. Longer cooling cycles mean you also get quieter operation and better humidity control. Two-stage units can remove more moisture from the air compared to a single-stage unit.
Should I cover my air conditioner or heat pump during the fall and winter?
It’s not necessary to cover your unit, especially if you have a heat pump you use throughout the year. Outdoor units are built to endure the elements, including rain and snow. Covering a unit may trap moisture, which can lead to mold growth or damage the electrical components inside. It can also make your unit an attractive shelter for rodents. If you’re concerned about yard debris getting inside the housing, there are short covers available. In many cases, checking your unit occasionally and removing any leaves or debris that has accumulated is enough.
What’s the best thermostat to use for my heating system?
This depends on the type of system you have. There are programmable and non-programmable models available, each of which is designed to help you maximize your heating system’s performance. We can offer recommendations to help you choose a thermostat that meets your household’s heating needs.
What’s a heat pump?
Heat pumps are all-in-one units that offer both heating and air conditioning. During warm temperatures, you can use your heat pump like a regular air conditioner. Heat pumps extract heat from inside your house and transfers it outside. During the winter months, the process is reversed – the heat pump will collect heat from the outside air and transfer it indoors. Even though the outdoor air feels cold, it still contains some heat. When there’s not enough heat to warm your home to the desired temperature, heat is supplemented with an electric heater. Heat pumps are very energy efficient, producing two to three times more energy than they use.
Heat pumps can also be a good add-on to use with your existing gas furnace. This is called a dual-fuel system. The two systems share the heating load, but they don’t operate at the same time – each one will operate separately when it’s most cost-effective. The heat pump works as the primary heating and cooling system for most of the year. When temperatures get too cold for the heat pump to heat the house efficiently, the gas furnace takes over. Once the temperature has risen to allow the heat pump to heat the home efficiently, the system will switch back to it.
Why should I zone my house?
Zoning allows you to divide your home into separate “zones” that can be heated or cooled separately. This means you can turn off the air conditioning for unoccupied rooms or have separate rooms set to different temperatures. Zoning only works properly with variable capacity systems as air flow (CFM) to each zone can be customized to fit the space. Two stage systems have limited capacity for only 2 large zones instead of 4 zones like the variable speed systems.
The benefits of zoning are:
You can adjust the temperature and airflow in one area of the home without affecting the others, allowing you to make each area as comfortable as possible.
- Energy efficiency:
Since you’re able to avoid heating or cooling unoccupied areas, you can see significant savings on your energy bills.
Zoning puts you in control of the temperature and airflow.
- Quiet performance:
When zoning is integrated with a variable speed or two-stage HVAC system, zoning allows your system to operate at peak performance and efficiency. It won’t need to run at peak capacity, which means it’s operating at lower, quieter speeds.
What is AHRI?
AHRI stands for the Air Conditioning, Heating, and Refrigeration Institute, a trade association that represents over 350 HVAC manufacturers. ARHI provides three performance certifications programs for residential and commercial air conditioning, heating, water heating, and commercial refrigeration equipment:
- ARI Performance Certified for air conditioning and refrigeration equipment and components
- GAMA Efficiency Rating Certified for space and water heating equipment
- I-B-R for hydronic heating products
ARHI is globally recognized for its unbiased evaluations of HVAC equipment. They also develop performance standards for industry equipment. The AHRI Product Performance Certification Program is a voluntary program that ensures heating, ventilation, air conditioning, refrigeration, and water heating products perform according to manufacturers’ published claims. For homeowners, choosing AHRI-certified products ensures you’re getting quality equipment that is quiet, efficient, energy-star rated, and high-performance.
What’s the difference between ARI and AHRI?
ARI stands for Air Conditioning and Refrigeration Institute. In 2007, the organization changed its name to Air Conditioning, Heating, and Refrigeration Institute, hence the acronym AHRI.
What is a “properly matched” system?
Most split HVAC systems are comprised of two parts: an indoor air handler that contains the evaporator coil and a blower fan, and an outdoor unit that contains the compressor and condenser coil. Both parts of the system are connected by copper or aluminum lines that circulate the refrigerant between the two units. “Properly matched” refers to the compatibility of the indoor and outdoor components and the refrigerant. Since all the parts work together, it’s important that they’re compatible. Having a properly matched system is important to get the best performance from your heating and cooling – and it prevents the possibility of premature equipment failures and system inefficiency.
What’s the difference between the Lennox Equipment Limited Warranty and the Lennox 10-Year Extended Limited Warranty Program?
The Lennox Equipment Warranty provides basic coverage on all units. The Lennox 10-Year Extended Limited Warranty extends the basic coverage for an additional 5-years with registration.
Is there a difference between air conditioner and heat pump decibels?
Heating and cooling systems produced today are a lot quieter than they used to be – but sound ratings among them do vary. For the most part, all heating and cooling systems on the market are significantly quieter than in the past. Lennox air conditioners and heat pumps, in particular, are among the quietest. They feature insulated compressor components, discharge mufflers, and unique fans designed to provide quiet airflow.
Are all air filters created equal?
No; there are a variety of differences between air filtration systems. Here’s a breakdown of some of the options and features available.
- Efficiency – Efficiency is one of the most considerations when purchasing a system. Efficiency is based on the size of the particles you’d like to filter out of your home. The higher the efficiency, the more effective your system will be. You can determine the efficiency of the systems based on the MERV (Minimum Efficiency Reporting Value) number. This is the industry standard rating. Residential filters generally have a MERV rating between 1 – 8. The higher the rating, the more efficient the system. High-efficiency particulate air systems use hospital-grade filtration, which can have a MERV rating of 17 or higher. Not only do higher efficiency filters clean the air, but they also improve the airflow. High-efficiency systems are best for individuals with allergies.
- Cost – Cost is another consideration when purchasing a filtration system. There’s the initial expense of the purchase price to think about, as well as the cost of maintenance and upgrades. Purchasing a filter that initially costs more and is of higher quality can save money in the long run. Less expensive filters may not provide you with the filtration you need, and they may cost more to maintain.
- Type – There are several types of filtration systems that offer different features, including:
- Pleated filters – pleated filters are made of fiberglass or synthetic fibers woven into a dense material. The pleats are arranged in V-shapes, which increases the area of the filter material without increasing the face area. This design increases the particle-holding capacity.
- Germicidal lights – these systems use intense UV lights to sterilize surfaces. UV lights kill organic growths, such as mold, bacteria, fungi, and viruses.
- Electronic air cleaners (EACs) – EACs pass recirculated air through a prefilter, allowing the system to trap large pollutants. Ionizing wires then apply a positive electrical charge to the particles. High-efficiency particulate air (HEPA) filters also effectively remove small particles. These systems can also work with carbon canister, which helps control odors and chemicals.
- Air Purifiers – Lennox is the only company that makes a hospital grade air purifier – PureAir. The purifier kit includes a UV light with titanium-dioxide-coated catalyst and Carbon MERV16 filter to remove odors, reduce particles and VOC’s in the home. The only air purifier that removes ozone.
What are the benefits of clean air?
Clean air in the home is very important, especially for people with respiratory issues, like allergies and asthma. According to the EPA, the average American spends 90% of their times indoors, where pollutants can be 2-5 times more concentrated than outdoors. Removing airborne particles can give allergy and asthma sufferers relief from their symptoms, but even those without respiratory conditions can benefit. Dust, smoke, and other particles float through the air and can be inhaled. By removing these particles, you reduce your respiratory system’s exposure to potential irritants.
What is an AHRI-matched system?
Split air conditioning and heat pump systems that have indoor and outdoor units must be properly matched to ensure the longevity of the system, as well as energy efficiency. An AHRI-matched system has been verified by the Air Conditioning, Heating, and Refrigeration Institute (AHRI) as a properly matched system. The system’s efficiency and capacity ratings have also been verified by the AHRI.
What is involved in humidifier installation and maintenance?
Humidifier installation is simple if you’re also replacing your furnace at the same time. However, it’s also easy to fit a humidifier to your current system since it’s designed to be installed in your ductwork. Humidifiers must receive regular maintenance to prevent bacterial growth. We recommend draining and cleaning the reservoir periodically.
How can I improve my indoor air quality?
There are several strategies for improving your indoor air quality.
First, identify the sources of indoor air pollutants and try to remove as many of them as you can. Cleaning and vacuuming at least once a week will help to decrease the amount of dust and dirt in your home. Bedding and stuffed toys should also be washed regularly. If you have members of the household who are sensitive to cleaning product fumes, store the products away and use them only when necessary.
Modern homes are well-insulated and designed to conserve energy; unfortunately, this doesn’t allow airborne pollutants to escape. You may want to consider having a Lennox Healthy Climate ventilation system installed. This recirculates indoor air with fresh, filter air from outdoors and helps to remove allergens and germs.
Some contaminants are so small they can escape vacuums or remain airborne, so if you’re particularly sensitive or have severe allergies, you may want have high-efficiency air filters or germicidal lights installed. Purification systems are also an option, as they remove particles, germs, odors, and chemical vapors. Improper humidity levels and high temperatures can also increase the concentration of particles and germs, so you may also want to consider a smart thermostat that can regulate moistures levels and temperatures.
How much water does a humidifier use?
This can vary depending on your model and the size of your home, but on average, humidifiers use from 1.5 to 12 gallons of water a day when the furnace is operating. This is enough to raise the humidity to the level you desire, but not enough to affect your water bill.
Why is ventilation important for proper indoor air quality?
We used to be able to receive natural ventilation in our homes by just opening a window. In more modern times, houses have been built with a focus on energy efficiency, effectively sealing our homes off from leaks and natural airflow. Unfortunately, this means that contaminants are trapped inside with no way to escape. Pollutants, allergens, and other types of contaminants cause poor air quality, which can lead to dizziness and headaches. For some individuals, they can also aggravate allergies and asthma. A ventilation system will keep your indoor air clean and re-circulated with fresh outside air.
What are the benefits of installing a whole-house humidifier?
Central heating allows us to stay warm throughout the winter, but it also traps us inside with unnaturally dry air for months at a time. Dry air can be harsh on our respiratory systems, exacerbating asthma symptoms as well as causing bronchitis, sinusitis, and nosebleeds.
Whole-house humidifiers work a lot like a room humidifier; they put a comfortable level of moisture in the air, which makes it easier to breathe. The difference is that they’re able to improve the humidity level of every room in your home, so you don’t have to move your humidifier around the house during winter.
What is the best indoor air quality product?
Many indoor air quality products available only address one to two classes of air contaminants. The PureAir™ and PureAir™ S air purification systems by Lennox handle all three classes of air contaminants, providing the most comprehensive air purification available. The PureAir™ and PureAir™ S both filter out particles and germs while removing and destroying chemicals. If you’re looking for an all-in-one system, these are an excellent choice!
Why is my throat so dry?
When the weather gets extremely cold, your home loses moisture to the outdoors. This causes the humidity level to drop – sometimes it can get as low as 10%. Inadequate humidity in cold weather is one of the major causes of respiratory infections. Adding a humidifier helps to add moisture into the air in your home and reduce ailments caused by dry respiratory membranes.
What do those air conditioner and heat pump ratings mean?
SEER stands for “Seasonal Energy Efficiency Ratio,” which is a system for rating the efficiency of cooling equipment. The higher your SEER rating is, the less it will cost to operate your unit. HSPF stands for “Heating Seasonal Performance Factor,” which is similar to SEER, but it’s used to measure the efficiency of the heating portion of a heat pump.
Why should I choose a whole-home dehumidifier for my home?
Many people try to deal with high humidity by lowering the thermostat while the air conditioner is running. However, this can raise your energy bills – not to mention, it may make your home uncomfortably cold. A whole-home dehumidifier removes the moisture from the air without needing to turn down your thermostat. Whole-home dehumidifiers have large capacities for moisture removal, and you won’t need to empty buckets of water. They’re quiet and designed to integrate into your existing central HVAC system, so they don’t take up additional space.
Why should I choose an ENERGY STAR® product for my home?
ENERGY STAR is a federal-sponsored program that’s designed to help consumers save energy and protect the environment by keeping them informed about energy efficiency. ENERGY STAR-approved products will have an ENERGY STAR approved label, designating them as an excellent choice for energy-efficiency.
Choosing an ENERGY STAR product rather than a conventional one can deliver hundreds of dollars’ worth of savings to your home. For example, an ENERGY STAR air conditioner can help you save as much as 50% on your cooling costs. However, in order to see the optimal performance from your system, it’s important to have proper sizing and installation of your equipment. Split system air conditioners and heat pumps must be matched with the right coil components in order to meet the energy star criteria. Depending on where you live, you may even qualify for a federal tax credit of up to $500 or utility credits for installing a new ENERGY STAR heating or cooling system.
Not only does ENERGY STAR products help save on energy costs, but they also contribute to a cleaner environment. In 2018 alone, ENERGY STAR helped save Americans $35 billion in energy costs while reducing 330 million metric tons of greenhouse gases, 220,000 short tons of sulfur dioxide, 210,000 short tons of nitrogen oxides, and 23,000 short tons of fine particulate matter.
For a long time, noisy HVAC systems have just been accepted as a part of keeping your home heated and cooled comfortably. SilentComfort™ is a technology used in select Lennox outdoor air conditioners and heat pumps. The SilentComfort™ outdoor fan motor has an electronic sensor that that optimizes the system’s performance while keeping the noise down to as low as 65 decibels. SilentComfort™ products also include thick insulation, vibration resistance, and a special fan blade that helps to keep sound levels low. Not only are these air conditioners and heat pumps highly efficient, but they’re also exceptionally quiet.
What is Indoor Air Quality?
Indoor air quality (also called IAQ) is a relatively new concern in regards to environmental safety. A home’s air quality is mainly based on the number of pollutants found indoors, but it’s also determined by humidity and ventilation levels. Amazingly, the EPA (Environmental Protection Agency) has found that pollutants can be concentrated in the home, up to 100 times higher than what’s found outdoors. With most people spending the majority of their time indoors, (90%, according to the American Lung Association) this is an important consideration. Clean air is extremely important to our health and wellbeing!
What is two-stage heating?
Two-stage heating means that the furnace has two levels of heat output. It will produce a high output on cold winter days, and a low output on mild days. The low setting is adequate for most heating demands 80% of the time, so a two-stage unit will run for longer periods, which provides an even heat distribution. There are no temperature swings like you’d find with a standard furnace, and temperatures can be regulated to within as little as one degree on your thermostat.
Two-stage furnaces start in the first stage when low heat is required. This means it doesn’t reach full capacity at one, causing a sudden blast of air. The low-speed operation also allows for better air filtration. The air is constantly passing through the filters, which allows them to capture more contaminants. Another benefit of a two-stage furnace is that they are more energy-efficient than a standard furnace.
How do the Lennox PureAir™ and PureAir™ S air purification systems work?
These systems work to reduce concentrations of pollutants in your home using a process called photocatalytic oxidation (PCO). This process is similar to the one used by the Department of Defense to combat germ warfare. PCO combines three powerful natural air purification methods: ultraviolet light, titanium dioxide, and hydroxyl radicals.
The PureAir PCO process involves:
- The pleated media filter captures particles and bioaerosols (like pollen or dander) and removes them from the airstream.
- As the airstream flows over the UVA light, it’s exposed to the catalytic surface containing the titanium dioxide-coated mesh filter.
- The energy from the UVA light activates the catalyst, releasing hydroxyl radicals, which are more than twice as potent as chlorine. The odors and chemicals in the airstream are broken down into carbon dioxide and water.
How do I know if a ventilation system is right for my home?
This can depend on a number of factors. Here are a few things to consider:
- When was your home built? If it’s a newer home, there’s a good chance it’s built to be more energy-efficient. Unfortunately, this can mean that it’s more airtight, which can cause concentrations of air pollutants to accumulate in your home.
- Have you upgraded your home to be more energy efficient? If so, you may need to add a ventilation system.
- How often are you able to comfortably open your windows to air out your home? If you find yourself keeping your home closed off due to outside temperatures, you may not be getting consistent ventilation.
- Do you often notice odors lingering in your home? This is a sign of poor ventilation and air circulation.
If you’re still unsure if you would benefit from a ventilation system, we’re happy to advise you!
What information do I need to register my Lennox products?
You’ll need the following information:
- Name, address, telephone number, and email
- Installation date (or closing date if it was installed in a newly constructed home)
- Product model and serial numbers
- The installing dealer or contractor’s name, address, and phone number
How can I add ventilation to my home without losing energy?
Lennox’s Health Climate® Collection is a line of ventilation products that are designed to bring fresh air into your home without the need to leave windows open. Using heat-recover ventilators (HRVs) and energy-recovery (or enthalpy-recovery) ventilators (ERVs), these products exchange stale, recirculated indoor air with fresh outdoor air, without wasting any energy.
HRVs and ERVs are electronic units that circulate the air in your home using its existing forced-air system or special ducts. HRVs are generally recommended for cooler climates, as they use heat from the outgoing air to warm up the fresh air coming into the home. ERV is climates with high outdoor humidity, as they remove the excess moisture from the fresh air that’s being circulated in from the outside.
How do I know which indoor air quality product is right for my home?
Lennox offers a Healthy Solution Finder, which can help you find products based on your home’s air quality issues. You can also contact us directly to schedule an evaluation!
How can I improve the ventilation in my home?
Opening windows and using ceiling fans are two easy ways to keep the air in your home circulating, but it can also increase your energy bills when your heating or cooling system is running. Another thing to consider is opening windows can also invite pollen and other outdoor allergens into your home. A ventilation system is an easy, energy-efficient way to improve ventilation and reduce particles throughout the entire house.
What types of pollutants do the PureAir™ and PureAir™ S systems remove?
There are many air purification technologies available, but they’re only able to combat one to two types of air contaminants. Lennox PureAir™ and PureAir™ S systems are designed to remove and destroy all three classes, giving you complete air purification:
- Particles that are less than 100 microns in diameter, including pollen, dust mites, dirt, and pet dander
- Germs, including bacteria, viruses, mold spores, and fungi
- Odors and chemicals, including pet odors, cooking fumes, tobacco smoke, chlorine, cleaning supplies, paints, and solvents.
Can dry air affect my health?
Yes! Lack of humidity in the home has been linked to numerous respiratory ailments. Dry air can cause dryness in nasal membranes, the throat, and in the bronchial tubes, which can lead to an increase in respiratory infections. Fortunately, this can be easily solved with the installation of a whole-house humidifier, which adds moisture to the air.
How can I eliminate odors from my home?
Lighting candles and spraying air fresheners is one way to quickly mask odors, but these methods won’t eliminate them. In fact, the chemicals used in these products may only add contaminants to your home. The best ways to truly remove odors include:
- Improve the ventilation by opening windows, or consider installing a ventilation system.
- Clean the air, using an air purification system with photocatalytic technology, like the Lennox PureAir™ system. The PureAir™ removes and destroys odors, including those from cleaning supplies, solvents from carpeting and paint, cooking smells, and pets. Another option is the Healthy Climate Carbon Clean 16 media air cleaner, which has a carbon-coated fiber matrix that’s very effective in controlling odors. High-efficiency particulate air (HEPA) systems can also help clear away odors. If the odors in your home are caused by bacteria, dust mites, animal dander, cat saliva, or mold, a germicidal UV light will inhibit the growth of germs and sterilize the surfaces in your heating and cooling system.
If you have any questions about air quality control products for your home, give us a call! We can work with you to select a system that is tailored to your odor control needs.
Can indoor air humidity levels impact my energy bills?
When the humidity in your home is high, it can feel warmer than it actually is. By removing the excess moisture in the air, you’ll be able to set your thermostat to a high temperature while still staying comfortable. According to the U.S. Department of Energy, you can save approximately 5 -7% on your cooling bill for every two degrees you raise the indoor temperature during the summer.
What causes indoor air pollution?
The U.S. Environmental Protection Agency states household items that release gases are one of the main causes of indoor air pollution. This includes carpet, upholstery, gas appliances, paints, solvents, cleaning products, air fresheners, dry-cleaned clothing, and pesticides. If you have an attached garage, fumes from gasoline, oil, and antifreeze may also seep into your home. Cigarette smoke and wood stoves also contain harsh chemicals.
Poor ventilation in the home can make the problem worse, trapping pollutants indoors. This is especially true in newer, air-tight homes that are designed to maximize energy efficiency. High temperatures and humidity can also increase the concentration of pollutants.
How can I control my home’s energy costs?
Heating and cooling your home can make up to 44% of your utility bills, so choosing an energy-efficient system can go a long way in controlling costs. When selecting a system, pay attention to the SEER rating of air conditioners and the AFUE rating of furnaces. The higher the ratings, the more savings you’ll see on your bills.
Some other factors you should consider:
- Regular maintenance will keep your system operating at peak performance.
- Zoning can cause a dramatic drop in costs because you’re only heating and cooling the areas of your home that you’re using.
- Programmable thermostats can reduce your heating costs by up to 35% and cooling costs by up to 25%.
Contact us for more energy-saving ideas!
Is air pollution only outdoors?
No. The U.S. Environmental Protection Agency (EPA) has found that pollutants inside the home can be up to 100 times higher than outdoors. Many common household items can release pollutants, including furniture, carpeting, and gas appliances.
When it comes to allergens, pets aren’t the only culprit! Pollen can invade the home through open doors and windows; it can also be carried into the house by pets or family members. Damp areas of the home can also lead to mold and mildew, while fibers like clothing and curtains can collect dust.
The Lennox SLP98V gas furnace claims to be the most efficient and quietest on the market; other manufacturers make similar claims. How can I know if this is true?
To be sure you’re selecting the quietest, most efficient furnace, we recommend checking how the unit was tested and the standard that it’s being rated by. The Lennox SLP98V, for example, comes with a disclosure that explains the testing conducted on the unit, as well as the standard that was used.
How can I provide fresh air exchange?
There are two different types of units that provide fresh air exchange. A heat recovery ventilator (HRV) uses fans to pull in fresh outdoor air while removing stale indoor air. An energy recovery ventilator (ERV) works in a similar way, but it uses a rotary energy recovery wheel. Both types of units work by transferring temperature and moisture from one air stream to the other, without mixing the air streams. HRVs and ERVs are energy-efficient, easy to maintain, and easy to use.
What should I do about carbon monoxide in my home?
Carbon monoxide is an odorless, tasteless, clear gas that can be a serious health hazard. The best way to detect carbon monoxide is to use a carbon monoxide detector. These devices monitor the air in your home for a certain level of the gas, similar to how a smoke detector works. It’s recommended to have one detector in the area adjacent to each room of your home. Like smoke detectors, carbon monoxide detectors work best with preventive maintenance.
How do germicidal lights work?
Germicidal lights are installed in the ductwork to destroy bacteria, viruses, and protozoa. They work by emitting strong rays of ultraviolet light, which penetrates the cell walls of the contaminants. This damages them, preventing the ability to grow, multiply, and spread through your home. Germicidal lights work continuously, even when your heating and cooling system isn’t running.
What causes high humidity in the home?
Homes located in coastal or warm weather regions are more likely to experience humidity, but all homes can experience high humidity regardless of where they’re located. Basements are prone to dampness, which can impact indoor air, as well as showering, dishwashing, and many other everyday activities.
How do home ventilation systems work?
Ventilation systems act a lot like our respiratory systems. They take in fresh outdoor air and expel stale indoor air, odors, household chemicals, and pollutants outside. This gives you fresh clean air in your home, which makes it easier to breathe. The Lennox Healthy Climate Solution is an energy-recovery ventilation system that transfers the stale air to the outside without wasting energy you’ve spent on heating, cooling, or dehumidifying.
My current furnace cycles so loudly, it wakes me up while I’m sleeping. Is there a quieter furnace available?
The Lennox SLP98V gas furnace has a variable speed motor that slowly (and quietly) comes up to speed, without creating a loud rush of air. It ramps down slowly too, either cycling off or continuing to run in a slow, quiet fan-on mode.
What’s so special about Lennox Dealers?
Lennox Dealers (like PECO) have been selected for their high standard of HVAC service. Our team is trained to perform installation, repairs, and maintenance on Lennox equipment, and is committed to providing the highest level of customer care.
How can I tell if I have a ventilation problem?
There are several signs your home has a ventilation problem. You may see moisture buildup on the windows or walls, or the air may feel stuffy or smell odd. Odors that linger in your home for a long time can be another indication of ventilation issues.
Why is proper air circulation important in my home?
Proper airflow in your home helps to keep the temperature regulated, but more importantly, it prevents the buildup of particles and mold. This makes it easier to breathe indoor air, especially for those with allergies or asthma. If you cook a lot or use craft supplies like paint or glues, proper air circulation helps to dissipate odors and fumes.
What should I know about changes in refrigerants?
The Environmental Protection Agency (EPA) regulates the production and use of refrigerants. After the passage of the Clean Air Act, refrigerants containing chlorine are being phased out because they contribute to ozone depletion. Many air conditioning and heat pumps on the market now use the R410A chlorine-free refrigerant in place of traditional R22 refrigerant (known as Freon). Since R410A is chlorine-free, it’s environmentally responsible – and it offers greater efficiency than R22. It’s better for the ozone layer and energy bills!
Why should I be concerned about my home’s air?
The Environmental Protection Agency (EPA) has found the air inside the average home is up to five times more polluted than outdoor air. Some people may only notice watery eyes or a runny nose while inside, but sensitive folks like seniors, children, and those with allergies and asthma may have severe respiratory symptoms that can become chronic.
The most effective way to keep your indoor air clean and healthy is to improve air quality. While vacuuming and dusting will help, the best way to capture and remove contaminants is with a filtration system.
The Lennox Healthy Climate Carbon Clean 16 Media Air Cleaner combines the industry-leading MERV 16 filtration with activated, carbon-coated fibers that remove airborne dust, pollen, pet dander, and other particles that can affect your respiratory health. It cleans the air throughout your home and is compatible with any heating or cooling equipment.
High-efficiency particulate air (HEPA) systems are also highly effective for removing allergens and contaminants. HEPA system performance is equivalent to a MERV 17 filtration system or higher. Lennox PureAir and PureAir S purification systems also work to filter out allergens while removing odors and chemicals. They offer better ability to clean the home than any other single system on the market.
Does the SLP98V gas furnace work in a dual-fuel application?
Yes! You can also get better efficiency pairing your furnace with an electric heat pump. This dual-fuel combination will help you control your heating costs by alternating between the two energy sources. It will switch between them depending on outdoor conditions.
How is a home purification system different than a filtration system?
Filtration systems reduce the concentration of airborne particles and biological pollutants. The Lennox PureAir and PureAir S purification systems use hospital-grade filtration and patented photocatalytic oxidations technology which destroys particles, germs, chemical vapors, and home odors. They are the only single system that removes chemical vapors like tobacco smoke.
What does ISO 9000 mean?
This refers to a group of international standards for quality management, covering everything from design and production to procurement and delivery processes. When you see the ISO 9000 designation, it assures you that the manufacturer followed a consistent process in producing their equipment and that their products meet the most demanding standards in the industry.
What are some of the health effects of carbon monoxide?
Carbon monoxide (CO) inhibits blood cells from being able to carry oxygen to body tissues and vital organs like the brain and heart. When CO is inhaled, it combines with the red blood cells, bonding with them 200 times faster than oxygen. This creates a condition called carboxyhemoglobin saturation. As it makes its way to organs, it starts to asphyxiate or suffocate the body. CO is very dangerous because it takes the body much longer to eliminate it than it does to absorb it.
Do ozone generators make the air worse to breathe?
Ozone is useful and effective for disinfecting water, which has caused some manufacturers to develop systems that use ozone for air purification. Unfortunately, the concentration of ozone needed to destroy germs and pollutants would need to be so high that it would be unhealthy to breathe. Researchers at the University of California, Irvine, discovered that some types of machines will produce such high levels of ozone that its comparable to peak smog levels in large metropolitan areas.
What is ozone?
Ozone is a natural form of oxygen found in the earth’s stratosphere, where it helps block harmful ultraviolet light from reaching the earth’s surface. In lower levels of the atmosphere, like the air we breathe, it’s a product of pollution. Since ozone can be dangerous, it’s important to avoid in-home purifiers that use it. Items like electric motors, vacuum cleaners, and refrigerators can be a source of ozone as well.
