Frequently asked questions.
Energy-Efficiency
How can I control energy costs?
Heating and cooling your home can represent as much as 44% of your utility bill.* With high efficiency ratings and innovative, industry-leading technology, Lennox home comfort systems can go a long way toward reducing these costs.
When selecting a new system, pay close attention to the SEER rating of the air conditioner and AFUE of the furnace. The higher the SEER or AFUE, the higher the savings.
Beyond efficiency ratings, other factors to consider are:
Maintenance
You can ensure your system operates at peak performance by scheduling annual maintenance checks.
Zoning
A zoning system can drastically lower your heating and cooling costs. With zoning, you no longer have to pay to heat or cool areas of your home that are rarely used.
Programmable Thermostats
According to the Department of Energy, a programmable thermostat can reduce your heating costs by up to 35% and cooling costs by up to 25%.

What is two-stage cooling?
Two-stage cooling means the air conditioner or heat pump has a compressor with two levels of operation: high for hot summer days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.
Longer cooling cycles also translate to quieter, more efficient operation and enhanced humidity control. Compared to a single-stage unit, a two-stage air conditioner or heat pump can remove twice as much moisture from the air. This is important because when moisture levels are high, there's a higher potential for mold and other pollutant problems.
What do all those air conditioner and heat pump ratings mean?
SEER (Seasonal Energy Efficiency Ratio) is a system for rating the efficiency of cooling equipment. The higher the SEER rating, the less your unit will cost to operate.
HSPF (Heating Seasonal Performance Factor) is a measurement similar to SEER, but it measures the efficiency of the heating portion of a heat pump.

What is two-stage heating?
Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and provides more even heat distribution.
Longer, low-capacity operation has many advantages:
Consistent comfort
Two-stage heating eliminates the temperature swings associated with standard furnaces, regulating temperature to within as little as one degree of the thermostat setting.
Quiet operation
Two-stage furnaces start in the first stage, when the amount of heat required is lower, instead of reaching full capacity all at once. That means there's no sudden "kick" or blast of air.
Improved air filtration
Low-speed operation allows your filters to capture more contaminants (because air is constantly passing through them), so you can breathe easier.
Efficient performance
Because the furnace operates mostly in its lower-capacity first stage, it burns less fuel than a standard furnace that always runs at full capacity and shuts off when the heating demand has been met.
Why should I zone my house?
A zoning system is designed for the many ways you use your home. Maybe you're caught up in family "thermostat wars?" Or perhaps you have unoccupied areas that do not need conditioning? A Lennox zoning system allows you to divide your home into separate areas, giving you the comfort and control you've always wanted.
The main benefits of residential zoning are:
Comfort
Zoning meets the specific temperature and airflow requirements of one area, without affecting other areas.
Efficiency
A properly designed zoning system can save you hundreds of dollars in energy costs each year.
Control
Zoning divides the home into different areas and comfort into different levels, giving you more choices and control than ever before.
Quiet Performance
When integrated with variable speed and/or two-stage HVAC systems, zoning allows your heating and cooling equipment to deliver peak performance and efficiency without continually operating at peak capacity. Lower speeds mean lower sound levels.
