Furnace and Air Conditioning Tracking System (FACTS)

Furnace and Air Conditioning Tracking System (FACTS) image FACTS is a multi-distributor study of the residential furnace, air conditioner and boiler market in Wisconsin. Since 1997, Focus on Energy has contracted with the Energy Center of Wisconsin to collect quarterly shipment information on residential forced air furnaces, air conditioners and boilers. The purpose of FACTS is to provide Focus on Energy with timely data regarding the market share of efficient home heating and cooling equipment in Wisconsin.

Data collected through FACTS is instrumental in understanding state-wide trends in the sales of high efficiency residential heating and cooling equipment. We currently estimate that the data provided by our partners represents between 65 and 75 percent of the residential heating and cooling market in Wisconsin.

The Energy Center gathers and then analyzes quarterly data given to us by participating residential HVAC equipment distributors across the state. In return for their quarterly data, we provide distributors county-level reports quantifying their share of the home heating and cooling market relative to the other participants.

We currently collect information for the following markets:


  • Efficiency level (above or below 90% AFUE)
  • Whether furnaces are equipped with an ECM motor
  • By county

Central air conditioners

  • by SEER level
  • by county


  • Size: <150 kBtu/hr, 150-299 kBtu/hr, 300-500 kBtu/hr or 500+ kBtu/hr
  • Efficiency Level: <85% AUFE, 85-89% AFUE or >90% AFUE
  • Modulating or non-modulating
  • By zip or county
