Scheduling an A/C tune-up before the heat of summer sets in assures you that when it’s time to turn it on, it’ll run dependably and as efficiently as possible. While you can do some tasks associated with the maintenance yourself, like changing the air filter and cleaning the outdoor condensing coil, a pro can go deeper into the system.

A/C Tune-Up Checklist

Typically, a professional includes these steps when performing routine maintenance for central cooling systems:

  • All the electrical connections are checked, cleaned and adjusted. When electrical connections and components are dirty or loose, the system loses efficiency. A loose connection can cause the part to get hot, which may cause an electrical fire. The HVAC technician will also check the safety features on the system.
  • Refrigerant pressure is measured. If it’s too high or low, the system won’t run as efficiently. If it’s too low, it may not run at all, or the evaporator coil can freeze over, damaging the compressor.
  • Meters are used to make sure that the amps and volts are correct for each motor.
  • Moving parts are lubricated, and belt tension and wear is checked.
  • Ductwork is inspected if there’s evidence of a leak. Dirt collecting near the registers can be a sign of a leak, as can rooms that are uncomfortable. Those leaks increase energy consumption and degrade air quality.
  • Your tech verifies that the drainpipe is clear. This part of the A/C tune-up will help you avoid costly water damage to your home if the pipe has a blockage. Mold deposits, vegetation and even insects can slow the drainage or plug the pipe altogether.
  • The evaporator coil and the condensing coil are deep cleaned, if needed. The evaporator coil needs periodic dusting and cleaning if it’s covered with mold or biofilms. The technician will check the condenser’s coil and clean if necessary.
  • Operation of the thermostat is tested and recalibrated, if necessary.

Scheduling your A/C tune-up early can prevent the system from failing when you most need it. To learn more, contact Indoor Solutions, Inc., serving Columbus and Pine Mountain, along with the surrounding area since 2005.
