Designed from the ground up to clean the air like nothing before, CleanEffects makes the air in your home feel cleaner and fresher than you thought possible. As an accessory to your matched Trane system, CleanEffects: removes up to an incredible 99.98% of allergens from filtered air, traps particles as small as .1 micron in size, up to 100 times more effective than standard 1" filter, can reduce your need to dust by up to 50%, has had its performance verified by leading experts at the Harvard School of Public Health.

The Honeywell F100 Whole-House Media Air Cleaner, F300 Electronic Air Cleaner, and Ultraviolet Air Treatment Systems work with your heating and cooling system to clean the air going through your duct system. As air re-circulates, up to 99 percent of airborne dust, pollen, smoke, pet dander, mold spores and certain bacteria that pass through the system are captured- dramatically better than a typical one-inch furnace filter. And unlike portable air conditioners, the Honeywell Air Cleaners are installed out of sight to work quietly and invisibly.


Trane gas furnaces are packed with state-of-the-art technology for exceptional, cozy comfort.

Heat Pumps

XLi heat pumps are designed and engineered to meet rigid specifications, tested to ensure excellent performance, and manufactured to last. Each unit is also designed to deliver exceptional reliability and energy efficiency all day, all night and for years to come. XLi heat pumps thoroughly condition your air, making your home environment ideal.

Heat Recovery Ventilation

A heat recovery ventilation system from LifeBreath moves stale, contaminated, warm air from inside the house to the outdoors. At the same time it draws fresh, oxygen-laden air from outside and distributes it thorough the house. Stale, polluted air is constantly being replaced by and equal quantity of fresh, clean air.


Today's homeowners are more willing than ever to invest in products that save water and energy - and save them money. TrueEase humidifiers do it all by only running water and air through the system when humidity is needed; using up to 50% less water; and saving energy by eliminating the constant cycling of air.

Plus, since humidified air feels warmer, your customers can turn their thermostats down to help reduce heating bills.


Programmable thermostats from Trane, Honeywell, and Venstar offer energy efficiency, security and remote access.

Zoning Solutions

According to a Decision Analysts survey of over 25,000 homeowners, 61 percent say they're dissatisfied with their home comfort system, and the number one complaint is uneven temperature. With Honeywell, you'll have access to the most extensive leading-edge zoning product line available, including conventional, communicating and wireless zone systems and dampers.
