Solution: 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. As an added benefit, many two-stage compressors use the new R410A refrigerant, which meets U.S. government standards for environmental safety.

Solution: Variable speed heating
Variable speed operation minimizes up-and-down temperature changes. A greater degree of precision means you stay perfectly warm, even on the coldest winter days. Compared to conventional furnaces with single-speed motors, variable speed systems use about two-thirds less energy. They’re also more effective at drawing moisture from the air for improved indoor air quality and comfort.

Solution: Comfort control
An essential part of your home comfort system is control, and this can take shape in one or two ways. Programmable thermostats allow you to fine-tune comfort settings based on your schedule, and zoning systems let you customize comfort according to the different ways you use your home.
