Home Comfort System

Your home comfort system is essential to keeping you warm in the winter and cool in the summer. It also helps protect you from allergens and pollutants year round. A home comfort system is made up of four major components: a thermostat, a furnace, an air conditioner or a heat pump and an indoor air quality system.

How does a home comfort system work?

Starting with the thermostat, the command center for your comfort system, when the temperature inside drops below or rises above the thermostat setting, the thermostat signals your comfort system to kick on or increase power.

In the case of the furnace, whenever the temperature gets too cold, the thermostat starts the fan motor so that the system’s fan can begin drawing room air through vents and ductwork. When air reaches the furnace cabinet, it passes through a filter, air cleaner or other air quality system. It also moves through a heat exchanger, which warms the air. Then, heated air is blown back into ducts and living areas.

During summer months, the furnace is still working, even though it’s not heating rooms or burning fuel. It acts as an air delivery system for the air conditioner, located outside the home.

So how does the air get cooled?

When the thermostat senses the temperature is too warm, it activates the air conditioner compressor, which pumps refrigerant through a loop of piping that runs between the outside air-conditioning unit and indoor cooling coil. As refrigerant passes through the cooling coil, typically installed on top of the furnace, heat is extracted from the indoor air circulating around it. The furnace blower then sends the conditioned air to living spaces through ductwork.

That’s basically how a home comfort system works. Keep in mind, not all systems are created equal. With a Lennox home comfort system, you can enjoy the highest possible degree of comfort, energy efficiency and customizable control.

Air Conditioners – XC21

The Dave Lennox Signature^® Collection XC21 air conditioner uses the most innovative features available to deliver the most quiet and efficient central air conditioner you can buy*. It provides ultra-high efficiency cooling with two stages of operation. It runs at low stage 80% of the time to reduce energy costs and sound levels.

*A combination of sound ratings established per ARI's test standard: 270; and efficiency ratings established per ARI's test standard: ANSI/ARI 210/240-2005.

Indoor Air Quality System – Humiditrol^® Whole-Home Dehumidification System

The Humiditrol^® Whole-Home Dehumidification System manages the moisture in your homeï¿½s air for greater comfort and improved indoor air quality. It also helps make you air healthier by mimimizing the impact of many potential indoor pollutants.

Indoor Air Quality System – PureAir™ Air Purification System

The PureAir™ Air Purification System cleans the air in your home better than any other single system you can buy. It helps control everything from microscopic dust mites and mold spores to infectious bacteria and viruses. And it's the only indoor air quality system that safely removes and destroys odors and chemical vapors. It uses patented photocatalyic technology to filter, purify and freshen the air, and it combines these capabilities into one integrated system.

SunSource® Home Energy System

The SunSource® Home Energy System breaks new ground in household comfort and beyond by harnessing power from the sun. With the help of modules mounted on the roof, it converts sunlight into electricity that can be used to run your heat pump or air conditioner, reducing your heating and cooling bills by up to half. Solar electricity can also be used to operate your appliances and other electronics in the home.

What’s included in a SunSource system?

Solar-ready outdoor unit. Products like the XC21 air conditioner or XP17 heat pump are engineered for quick and easy integration with solar modules in a complete SunSource Home Energy System.

Solar modules. One to 15 modules on your roof or in your yard capture the abundant, clean and completely free energy of the sun to reduce your home’s utility costs.

Communication module. Installed inside your home, this module sends performance information for each solar module to a website, where you can view system status and see environmental benefits in real time.

Why invest in a home energy system?

It saves you money on utility bills. With demand for electricity rising, right along with energy costs, utility bills can get extremely high. The bulk of a home’s energy costs, up to 56%*, comes from heating and cooling. The SunSource Home Energy System provides a bright spot of relief by significantly reducing your monthly utility bills. Energy tax credits offer an added opportunity for savings.

It benefits the environment. The SunSource Home Energy System reduces the need for electricity generated by power plants, which in turn leads to a reduction in the greenhouse gas emissions that are believed to contribute to climate change.

It allows you to go solar on your terms. You can start small, with one or two modules, and add more (up to 15 total, per outdoor unit) when your needs change or budget permits.

Precise Comfort™ technology

The SLP98V from the Dave Lennox Signature^® Collection is engineered with exclusive Precise Comfort™ technology, which creates perfect temperature and humidity by varying heat output in increments as small as 1%.

Variable-speed furnace technology

A variable speed furnace motor uses two-thirds less electricity than a standard single-speed motor. With the energy savings you enjoy each month, your investment in a Lennox variable speed furnace will pay off.

Two-stage cooling: air-conditioning

There's cool, and there's perfectly cool. Lennox^® air conditioners like the XC21 make the distinction with two-stage technology, which adjusts operating speed for a more precise temperature throughout your home.

Two-stage cooling: heat pump

Unlike typical single-stage heat pumps that operate only at full power, Lennox^® heat pumps like the XP21 and XP16 can adjust heating and cooling output to match household demand. They run mostly at low stage to maximize comfort and energy savings.

How a Heat Pump Works

Ideal for warmer climates, a heat pump is an efficient choice when you want mostly cool air and heated air only on occasion. Lennox^® heat pumps can also be combined with gas furnaces for ultimate comfort and energy savings.

icomfort Touch Thermostat

The easy-to-use icomfort Touch™ thermostat is the “brain” of the icomfort by Lennox™ system, sensing the environment and optimizing Dave Lennox Signature^® Collection flagship heating, cooling and humidity-control products to deliver the highest level of comfort and innovation you’ve ever experienced.

The icomfort Touch is designed with intuitive, menu-driven programming screens that make it easy to create a heating or cooling schedule that matches your comfort level and lifestyle needs. Plus, the icomfort Touch can be programmed to conserve energy.

Comfort Controls – ComfortSense^® 7000 Series Touchscreen Thermostat

The ComfortSense^® 7000 Series Touchscreen Thermostat controls every heating and cooling system in your home, offering precise humidity and temperature control and easy touchscreen operation.

Lennox^® 7-Series Ductless Mini-Split Systems

For individual rooms that are difficult to heat or cool, Lennox Mini-Split Systems are like having a dedicated air conditioner or heat pump in one specific area.

How it works
Your Lennox dealer mounts the indoor module, and connects it to the outdoor module through one small hole in the wall.
During the summer, your Lennox Mini-Split air conditioner transfers heat from the indoor module to the outdoor module, so your room stays crisp and cool.
On the other hand, if you've installed a Lennox Mini-Split Heat Pump, it will cool the exact same way during the summer, but during the winter, it will reverse the process to draw heat in, keeping your room cozy and warm.

Ductless Mini-Split Systems are an excellent choice for:
