If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading, replace it with a unit that has earned the ENERGY STAR. Replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill by nearly $200. But before you invest in a new HVAC system, make sure that the big air leaks in your house and the duct system have been sealed. Sometimes, these are the real sources of problems rather than your HVAC equipment. Call us at 303-993-9060 or check us out at www.premieraircolorado.com
