Air Conditioning Repairs and Servicing

Usually, an air conditioner needs repair when a part fails or it is low on refrigerant. Air conditioners are sealed systems and often only need more refrigerant when there is a leak on the system. If there is no refrigerant in the system, refrigerant must be added and then the system leak checked with a refrigerant sniffer.

Air Conditioner Maintenance Checklist

  1. Clean the outdoor condenser coil and check indoor evaporator coil. (The coil is made up of the refrigerant lines and surrounding radiator – like fins that line the cabinet of your outdoor A/C unit. The evaporator is the interior counterpart to the outdoor unit and has its own coil. Dirt and debris on the coils reduce efficiency and stress the systems mechanical parts.
  2. Check the refrigerant level. (An improper amount of refrigerant makes a compressor work hard, reducing the efficiency and longevity of the system.)
  3. Inspect the drain pan and condensate drains. (Drains must be unobstructed and clean to ensure excess moisture is not trapped in the unit or inside the house.)
  4. Check outdoor fan motor and blades and indoor blower assembly. (The fan on the outdoor unit pulls air in through the coil fins. The indoor blower is the fan unit (motor, fan wheel and housing) on your furnace.)
  5. Check compressor and refrigerant tubing.
  6. Lubricate moving parts. (As applicable: older A/C units often have ports on fan motors, compressors and other parts for adding lubrication periodically. Newer models typically have sealed parts that don’t need to be lubricated.)
  7. Inspect all electrical controls, wiring and connections. (All electrical components and hookups should be checked for soundness, wear and damage.)
  8. Run a general system test. (The technician should turn on the A/C system to check operating functions, such as the starting cycle and shut off control. Check for unusual noises or odors and measure indoor/outdoor temperatures. Sub cooling as needed.)
  9. Inspect and clean or replace air filters. (Standard filters only)
  10. Do a thermostat check and calibration. (Improperly calibrated thermostats cause the unit to run longer than necessary. Every degree your A/C operates below 22ºC can add 5% - 8% to the cost of cooling.
