Homeowners here in the Twin Cities often ask whether they need to have an annual service check-up for their heating and cooling systems. Experienced HVAC contractors will generally explain that the annual service check can protect the health of your home comfort system, much like an annual physical will keep your body healthy.

The annual service check can identify any small problems before they become big, expensive system breakdowns. Service visits from your local contractor will also keep your system tuned up and running at its most efficient level. This keeps utility bills under control and extends the life of your system. Long-term, economical annual maintenance visits will save you money and give you peace of mind. Here’s what you can expect the technician to do on an annual service visit:

  • Calibrate thermostat, check settings and provide recommended set points to help you save energy while staying comfortable at home
  • Test on-off controls to ensure the system starts up, runs, and powers off correctly
  • Oil all moving parts
  • Inspect fuel connections and heat exchanger, look for any leaking or cracking, check gas pressure, clean burner
  • Clean pilot light area, adjust pilot if needed
  • Check the heat exchanger
  • Examine belts for proper fit and excessive wear, adjust belts if needed
  • Check furnace safety devices
  • Replace air filter (Homeowners should learn how to change the filter and do so once a month during times of heavy use – between annual service visits.)
  • Check the level of refrigerant and add or remove as necessary
  • Inspect condensate drain (air conditioning) to prevent a clog, which often leads to mold problems or water damage
  • Clean evaporator, condenser and coils (air conditioning)
  • Clean the blower and adjust if necessary to increase air flow and efficiency
  • Inspect the electrical connections, check motor voltage and current for safety and efficiency purposes
