Just as a tune-up for your car can improve your gas mileage and save you from costly future repairs, an annual tune-up of your heating and cooling system can improve efficiency and comfort. When your system is not maintained properly its performance is reduced.
This can cause higher electric bills, wasted energy and damage to components. Even if warm air is flowing into your home, your system may require maintenance. Unfortunately, warm air is not a reliable indicator of heat pump and gas furnace health and heating performance. Many things can go wrong before your system stops heating.
