Change Dirty Air Filters

By · January 16, 2011 · Filed in Energy Efficiency, Green Solutions, Indoor Air Quality

Most modern heating equipment is designed for a maximum temperature increase of 25ºC to 45ºC,  while it is actively heating. If your air filters become dirty and reduce air flow, the efficiency of the unit substantially is reduced and relies on the high limit to cycle the burner off.  This reduces the life of the heat exchanger and leads to high limit failure.
