Check filters every month. Smell around the appliance for gas odors. Visually inspect exhaust vent for rust, damage or deterioration. Inspect the fan belt for cracking or fraying. Also check the belt's tension by pushing on the
center and ensuring it only deflects 1/2" - 3/4". Have annual system maintenance service performed during the fall to avoid the busy winter season. Become familiar with normal operating sounds.
Tips for better efficiency
Install a programmable thermostat
If your family is away from home for roughly the same times throughout the week, a programmable thermostat is a smart solution. If you use the pre-programmed settings effectively, you can save on energy costs.
Seal your heating and cooling ducts
Ducts move air all around your house, keeping you comfortably cool in the summer and warm in the winter. Leaky ducts can really sap your energy efficiency! Repair them with duct tape to increase your system's efficiency by up to 20%.
Seal ducts in those hard-to-reach (and easy to miss) places like your garage, attic, unfinished basement, or crawlspace. Tape up seams and connections for a tight seal and, for maximum efficiency, wrap the ducts in insulation. Seal any other ducts you can get to inside the house itself.
To increase the life of your heating and air conditioning unit, be sure the unit is plugged directly into the wall. Do not use an extension cord! The compressor may become damaged if it doesn't receive enough power on an ongoing basis.
