But you can reduce the cost of running the system. Homeowners can save on their heating energy bills by inspecting each of these parts. Even if it still works well, you could greatly benefit by replacing it with a new, energy-efficient model. If the price of a new system turns you off, Kelley said the energy savings should pay for the unit in only a few years. All machines work more efficiently and safely if you regularly inspect and maintain them.
Filters remove dust and debris before they reach the air blower and heat-exchange coils.
Dirt on heating coils reduces the system's efficiency. Kelley said your thermostat can be an energy-saving tool, too. When the system is constantly cutting on and off, it's wasting energy. For the winter, Kelley recommends a setting of 68 degrees during the day and 50 to 60 degrees at night and when no one's home. Another way to use your thermostat to your advantage is to replace it.
