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

Last updated 8 months ago

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.
