If your current heat pump or air conditioner is more than 10 years old and your furnace or boiler is more than 15 years old it’s probably struggling to keep your home cooled or heated.  This is because as your heating and cooling system ages it loses its ability to cool or heat your home.  They are at the end of their life and probably need to be replaced.  Call Premier Air Colorado, your heating contractor in Denver for a free estimate to have an energy efficient system installed.
