With cold weather upon us, it's time to tune up the home's heating system to ensure safe and energy-efficient use during the peak heating season. Be sure to turn off both the power and gas supply to the device before beginning your repairs. Start by replacing the filter. A clean filter will permit the blower not to work quite as hard. Next, clean and adjust the burners for the safest and most energy-efficient flame. The heat chamber should also be clean and free of debris. Use a vacuum hose with attachments to remove any debris within the chamber. Finally, tighten the fan belt that drives the blower so it doesn't sound like a screeching automobile each time the furnace operates. For more information or assistance, contact your utility company or a heating contractor. And that's the On The House tip for today.
