Solving Special Problems

Airconditioners take quite a beating over the course of a hot summer, so you can only expect that troubles will eventually arise. The problems that are related to an air conditioner are not necessarily always a big enough deal to call in the professionals for repair. Many times the problems associated with an air conditioner can be solved with some common sense troubleshooting steps.

Thermostat

  • Anytime the air conditioner is refusing to kick on and the warmth is getting uncomfortable, ensure that the unit is actually on. Examine the thermostat to see that the unit has not been turned off or that the thermostat has not been set too high.

Blown Fuses and Tripped Circuit Breakers

  • An air conditioner refusing to kick on despite a working thermostat means you should pay a visit to the main service panel before picking up a phone. In older houses, look for a blown fuse. Wiring systems work via the circuit breaker, so check that the breaker has not tripped. Replace a blown fuse, or reset the circuit breaker.

Dirty Air Filters

  • Look for dirty air filters if there is a noticeable change in the efficiency of the air conditioner's ability to cool quickly. Dirty and clogged air filters can significantly reduce the effectiveness of the air conditioner and cause it to work twice as hard to produce the same level of cooling.

Duct Obstruction

  • If a room appears not to be getting as cool as usual, look for obstruction to the airflow. Ensure that the duct register has not been closed or partially shut. If the ducts are located on the floor, ensure that airflow isn't obstructed by curtains or furniture

Condenser Airflow

  • Go outside to check on the outdoor unit for proper airflow. Obstructions to airflow will cause an air conditioner to work below peak efficiency, so make a habit of paying attention to the outdoor unit. Remove any vines that are growing along the outside of the unit. Look into the grille to see if the fan is obstructed by a foreign object. Prune back trees or shrubs that are blocking effective airflow to the unit.
