Before chilly autumn nights set in, you need to make an appointment for your furnace's annual checkup. Without this yearly cleaning and inspection, a system can wear itself out quickly, pump deadly carbon monoxide into your home, or simply stop working.
Whatever type of system you have (A/C and Furnace or Heat Pump), don't wait until it breaks down to call for service. A clean, well-adjusted heating system will save you money on fuel and prolong furnace life. Annual servicing is cheap—typically less than $100—especially when compared with the price of a new furnace.
