Keeping your heating and cooling systems in good working order means your utility bills will be lower, your home will be more comfortable, and you'll need to call for repairs less often.
Schedule a maintenance service call before the heating season starts. If there are any problems with your system, it's better to find out before it's freezing outside! Do the same for your cooling system before sweltering season begins.
Replace your heating and cooling air filters every month that they're in use. Operating your system with old, dirty filters means energy is wasted and your system may even be damaged. While you're at it, check and clean the filters in your home's air cleaners and humidifiers.
