Great Savings Happen When Two Energy Sources Work Together

When you combine a compatible Lennox® heat pump with an efficient Lennox® furnace, you can create an energy-saving dual-fuel system. The heat pump functions as both a heating and cooling system, reducing gas fuel consumption. On extra-cold days, the gas furnace becomes the primary heat source, ensuring maximum comfort is maintained.

Stay Comfortable—and Asleep

Peace and quiet are just as much a part of the perfect environment as temperature and humidity. That’s why many Lennox® heat pumps offer SilentComfort™ technology that produces some of the lowest noise levels in the industry.

Lennox® heat pumps are some of the most precise and efficient you can buy. Delivering effective temperature and humidity control, and efficient energy usage, Lennox® heat pumps keep your home’s temperature exactly where you want it. The units work like an all-in-one cooling and heating system, and are perfectly suited to warmer climates. During summer months, the heat pump works like an air conditioner, extracting heat from inside your home and moving it outdoors. When the weather turns cooler, the process is reversed as the unit collects heat from the air outside and transfers it inside. Extremely quiet and exceptionally efficient, Lennox® heat pumps deliver industry-leading efficiencies of up to 23.50 SEER and 10.20 HSPF, which can help save you hundreds of dollars every year in utility costs. For maximum flexibility and energy savings, single fuel and dual fuel models are available.

Whole-home Solutions for Complete Peace of Mind

Healthy Climate® air purification and filtration systems are designed to work with your central heating and cooling system. They improve the air throughout your entire home—not just in individual rooms—without producing ozone, a known lung irritant*.

The Most Effective Way to Improve Your Air

The PureAir™ air purification system is the only single indoor air quality system to combat all three classes of contaminants.

  • Allergy-aggravating particles such as dust, pollen and pet dander

  • Mold and germs that grow and reproduce in damp places, such as basements and crawlspaces

  • Odours and chemical vapours from paints, cleaning supplies and additives used in carpeting and furniture

Multiple Technologies Working Together in One Powerful System

PureAir™ reduces and removes contaminants with hospital-grade filtration and a powerful air purification technology called photocatalytic oxidation (PCO).

Other Smart Solutions for a Healthier Home

The Carbon Clean 16® media air cleaner is the #1 rated, professionally installed, whole-home filter as rated by a leading consumer magazine*.

A Bright Solution for Controlling Germs

Healthy Climate germicidal lights use intense rays of ultraviolet light to control contaminants.

A Lennox® PureAir™ whole-home air purification system improves indoor air quality better than any single system you can buy. Many technologies only combat one or two categories of air contaminants, and often only in a single room. The PureAir air purification system is the only single indoor air quality system to combat all three classes of indoor air contaminants—particulate, bioaerosols and Volatile Organic Compounds (VOCs). The PureAir air purification system reduces indoor air pollutant levels through a combination of hospital-grade filtration and a contaminate removal process called photocatalytic oxidation (PCO). The process involves three steps. Step one, the Carbon Clean 16® filter captures particles and bioaerosols as small as 0.01 micron, removing them from the airstream. Step two, as the odor-and-chemical-vapor-filled airstream flows through the PCO cartridge, the airstream is exposed to the catalytic surface (titanium-dioxide-coated PureAir cartridge). Step three, the light energy from the UVA lamp and catalyst work together to break down odours and chemical vapours into harmless carbon dioxide and water. Unlike other air purification products on the market, the PureAir system does not produce any ozone as a by-product and actively works to reduce ozone, a known lung irritant.

A Healthy Climate® humidifier works with your heating system to keep the air inside your home from becoming too dry and causing wintertime chapped skin and respiratory problems. Plus, it’s more effective and easier to maintain than a portable humidifier.

Sticky Conditions Outside Call for Lennox® Innovation Inside

Designed to work with premium Lennox® equipment, the Humiditrol® whole-home dehumidification system uses patented technology to remove excess moisture from your home. Dehumidifiers are also available that work with all brands of heating and cooling equipment.

When your home’s air is properly humidified, your whole home feels better. Lennox® Healthy Climate® whole-home humidifiers and dehumidifiers efficiently control moisture levels in your home without producing ozone, a known lung irritant. In the wintertime, a Healthy Climate whole-home humidifier works with your HVAC system to add humidity to your indoor air, stopping it from becoming too dry and uncomfortable. In the summertime, a Healthy Climate or Humiditrol® whole-home dehumidifier removes excess moisture from the air, making your home feel less sticky and hot. Too much moisture in your home’s air not only makes the atmosphere feel heavy and damp, but it also promotes the growth of mold and mildew, which can aggravate allergy sufferers. Properly dehumidified air is not only healthier and more comfortable, but it can also reduce your summertime energy bills. Dehumidified air feels cooler, so you can set your thermostat at a higher temperature and still feel comfortable. In fact, for every two degrees you raise the temperature during the summer, you can save between 5% and 7% on your cooling bill.

A Refreshing Option for Healthier Air

Today’s newer homes are often tightly sealed for efficiency, but this can make the air stuffy. Also, allergens and contaminants can stay trapped inside. Healthy Climate® ventilation systems offer a simple and effective solution, replacing stale indoor air with fresher outdoor air.

Better than an Open Window

Opening a window can make your air feel less stuffy, but this isn’t practical during the hotter and colder months of the year, plus it invites pollen and other allergens into your home. A Healthy Climate® ventilation system offers a better way to enjoy fresh air.

You Control the Comfort

With a Healthy Climate® ventilation system, you can easily adjust the amount of fresh air entering your home using simple, intuitive controls.

Freshens Without Producing Ozone

Unlike some indoor air quality systems on the market, Healthy Climate® ventilation systems freshen the air without producing ozone, a toxic gas that can irritate the lungs*.

Ideal for tightly sealed homes, Lennox® whole-home Healthy Climate® ventilations systems replace stale indoor air with clean outdoor air, making your home feel fresher and less stuffy. Better than opening a window, which can let allergens and bugs into your home, a Healthy Climate ventilation system allows you to easily and efficiently control the amount of fresh air coming into your home. Well-suited for colder climates and dry or desert-like areas, the Healthy Climate Heat Recovery Ventilator (HRV) harnesses heat from inside your home and transfers it to the incoming fresh air. This heat recovery process enhances your comfort and helps control wintertime condensation, which can damage windows, insulation and furniture. Ideal for warmer and more humid climates with mild winters, the Healthy Climate Energy Recovery Ventilator (ERV) transfers moisture and heat from incoming fresh air to the outgoing airstream. In fact, it can remove nearly half of the moisture from the incoming air, helping to keep your home cool and dry. Unlike some indoor air quality systems on the market, both the HRV and ERV systems freshen the air without producing ozone, a known lung irritant.

Air Filters

Air filters are essential components of your heating and cooling system. They help improve the quality of your home’s air and keep your system performing at peak efficiency. The most common air filters are standard disposable cartridges, but advanced filtration systems and air cleaners are also available.

When to Change Air Filters

Standard, one-inch disposable air filters should be changed every three months. However, if anyone in your family suffers from allergies, or if you have pets or dust buildup in your home, you might want to change your filters every month or so. Advanced filtration systems have longer life spans and are usually maintained by HVAC professionals.

How to Change Your Air Filter

The process for changing standard disposable filters is fairly straightforward and involves just a few steps:

  • Locate your air filter Air filters are typically located in your system’s return air vent, which might be on the ceiling, wall or on the side of your furnace or air handler. Your air filter might also be housed inside the unit. If this is the case, you may have to remove an access panel to get to the filter.

  • Remove the air filter from its housing Simply open the return and pop out the old filter. If there is no filter in the return, measure the length and width of the space, so you’ll know what size filter you’ll need for replacement.

  • Note the size printed on the air filter frame If you removed an old filter, check its size so you can be sure you have the correct filter for replacement. If you have any questions about the size you need, you can refer to the owner’s manual for your furnace or air handler, or contact your local Lennox® Dealer.

  • Install the new air filter Securely slide the new filter in place of the old one, making sure you follow the arrows printed on the sides of the filter frame. These arrows point to the direction of the airflow, which should be toward your furnace or air handler.

  • Get help from your lennox® dealer If you have any questions about where your filter goes, or how to install a new one, your local Lennox® Dealer can help. If you have already replaced your filter, and your system makes excessive noise, contact your Lennox® Dealer to address the problem.

Consider More Advanced Filtration

Lennox® offers a wide variety of filtration products, including high-performance air cleaners that remove small, allergy-aggravating particles that standard filters can’t stop.
