Simple steps resolve air conditioner problems

Now that the weather has warmed up, it’s time to turn on the air condonitioner to keep your home cooler and less humid.

When a cooling (or heating)  system malfunctions, any one of its three components — heat/cold source, distribution system or thermostat — may be causing the problem.

  • If the air conditioner doesn’t run, the malfunction is probably at the source.
  • Theunit may have lost power.
  • If the air conditioner turns on but the cool air isn’t reaching the rooms of your home, the problem is likely to be the blower or distribution system.
  • A faulty control, or thermostat, could keep the system from turning on or could cause it to turn on and off repeatedly.

AmeriSpec Home Inspection Services checks air conditioners during an inspection.

Before you start work on a heating or cooling system, take these preliminary steps:

  • Make sure the unit is receiving power. Look for blown fuses or tripped circuit breakers at the main entrance panel.
  • If the unit has a reset button, marked RESET and near the motor housing, wait 30 minutes to let the motor cool, then press the button. If the unit still doesn’t start, wait 30 minutes and press the RESET button again. Repeat at least once more.
  • If the unit has a separate power switch, make sure the switch is turned on.
  • Check to make sure the thermostat is properly set. If necessary, for an air conditioner, lower the setting 5 degrees.
  • If the unit uses gas, check to make sure the gas supply is turned on and the pilot light is lit. If it uses oil, check to make sure there is an adequate supply of oil.
