Air Conditioner Problems? Troubleshooting Tips For Homeowners In San Fernando And Santa Clarita valleys

Last updated 4 years ago

By Diane, Pacific Aire Comfort Advisor, 

Air conditioner problems can be very frustrating because they always happen when you really need your cooling system. (OK, that's a little like saying you always find things in the last place you look, but you get the point.) Here in the San Fernando and Santa Clarita Valley areas, a heat wave can happen at almost any time of year, so it's a good idea to learn how do some simple A/C fixes on your own. 

Check out our basic troubleshooting tips when you notice the following symptoms:

If there is too little airflow (not much air coming out of the duct system):

  • Check to see that dampers are open. 
  • Look for a blocked or bent duct, and/or loose connections.
  • Examine the blower and air filter for dirt that may be clogging it, especially if it hasn't been changed in a while.

If the air conditioner stops working:

  • Check to be sure the system is turned on and set to “cool.” 
  • Make sure the set temperature is lower than the current room temperature. 
  • Check the outside components of your air conditioner (the compressor and condenser), and the blower (fan) and evaporator coil inside the house to be sure they're getting electricity.
  • Check the wiring for damage or disconnection. 
  • Be sure the power switches are on.
  • Look for blown fuses.
  • Be sure that the circuit breaker is in the correct (on) position. If it's been tripped, let the air conditioner cool down for 5 minutes, then reset the breaker or replace the blown fuse. 

If the A/C turns on but doesn't cool:

  • Try cleaning the equipment. First, turn off power and clear the area around the condenser outdoors. Use a brush to clean the grill's fins or vacuum with a brush attachment. 
  • Cover up wiring and motor with a trash bag. Then spray the fins with a low-pressure spray of water from a garden hose.
  • Now, put everything back together and test the system. 

If none of the above fix your air conditioner problems, it's time to call your local HVAC expert at Pacific Aire Heating & Cooling.
