HVAC FAQ Information

    The capacite is calculated by doing a load on your house where we measure the footprint of the house, the windows, insulation etc and input it into a program that will give us the size furnace and air conditioner we will use.
  2. How is the efficiency of heating and cooling equipment measured?
    For a furnace the least efficient would be 80% meaning 80% is used for heating and 20% is vented to the outside. The 95% furnace is one of the most efficient.

    The best way to increase the life of your furnace and air conditioner is having maintenance done twice a year and keeping the filters changed.
