AC Maintenance Checklist

Maintain your equipment to prevent future problems and unwanted costs.

Keep your cooling and heating system at peak performance by having AirOne Heating and Air Conditioning do bi-annual pre-season check-ups with our Comfort Society program.

A Typical Maintenance Check-Up Should Include The Following

a typical maintenance check-up form
  • Total Performance Diagnostics report to ensure the cooling and heating system are producing the system designed Btu capacity, operating at the energy saving SEER rating the cooling system was designed to achieve and gas heating systems are producing the designed Btu capacity designed by the equipment manufacturer.

  • Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.
  • Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
  • Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.
  • Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A plugged drain can cause water damage in the house and affect indoor humidity levels.
  • Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.

Cooling Specific

  • Clean evaporator and condenser air conditioning coils. Dirty coils reduce the system’s ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.
  • Don’t have your central air conditioner’s refrigerant level checked unless the Total Performance Diagnostic report shows it to be necessary since some system refrigerant is released every time the system is checked. Too much or too little refrigerant will make your system less efficient increasing energy costs and reducing the life of the equipment.
  • Clean and adjust blower components to provide proper system airflow for greater comfort levels. Airflow problems can reduce your system’s efficiency by up to 15 percent. Total Performance Diagnostics will indicate air flow problems on the report.

Heating Specific

  • Check all gas (or oil) connections, gas pressure, burner combustion and heat exchanger. Improperly operating gas (or oil) connections are a fire hazard and can contribute to health problems. A dirty burner or cracked heat exchanger causes improper burner operation. Either can cause the equipment to operate less safely and efficiently. Verify operation of all safety switches and devices.
  • Verify Operation of all electrical resistant heat elements and element controls. Check for burnt wires and proper amperage. Verify temperature rise. Verify operation of all safety switches and devices.

Actions To Do Yourself

  • Inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump. Your AirOne Heating and Air Conditioning technician can show you how to do this. A dirty filter can increase energy costs and damage your equipment, leading to early failure.
