Maintenance Tips   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. Maintenance Scheduling Schedule a maintenance service call before trouble finds you. If there are any problems with your system, it’s better to find out now what needs to be corrected! Do the same for your cooling system before sweltering season begins. Filters Replace your heating and cooling air filters on a timely basis. 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. System Checks If you have a forced air heating system check your furnace’s blower compartment and blower coils. Vacuum them if you see dirt and dust there. You should also check fan belt tension, and lubricate fan and motor bearings. If you have a recently newer furnace with electronic ignition, you can reset a locked out furnace by interrupting power to the control circuit. Bleed hot water system radiators at least once a year. Don’t keep clutter near your furnace. It’s a fire hazard, and may keep your system from operating efficiently. To make sure you’re getting the most out of your heating system, keep the heating registers and vents throughout the house free of dust, dirt, and pet hair by vacuuming them at least once a year. Listen for odd sounds when your heating or cooling system kicks in. If you hear anything unusual, get in touch with your service professional so you can head off problems before they become serious. In winter months, set your ceiling fan at its slowest speed and reverse it in order to gently push warm air down from the ceiling without generating a breeze.
