No Cool Air Problem DIY

At Fillmore HVAC we understand budgets are sometimes tight and you’d rather try to figure out the problem before calling us for service. Below is a potential problem with central air conditioning to help you better understand your HVAC and when you have a serious air conditioning repair problem. We're never insulted when people would rather ask about an air conditioning repair problem rather than ...call us to service one. 

No Cool Air Problem

1.) Remember to always refer to the owner’s manual and follow the guidelines.

2.) Some units with this problem may need cleaning. When completing this air conditioning repair, turn off the power to the unit. Typically, you’ll need to shut of the unit’s 240-volt circuit at the electrical panel and the panel next to the outdoor compressor.

3) Remove any debris away from the condenser (located outside). You don’t want anything blocking the airflow.

4) Unscrew the protective and top cover grilles from the compressor. Be careful if the fan is attached to the grille. You can unknowingly pull wires loose when removing it.

5) Use a (soft) brush to clean the debris from the fins

6) Use a vacuum—with a brush attachment—to vacuum the fins

7) Inside the unit, place plastic covering over the motor and wiring to protect them from getting wet (a plastic garbage bag works too). You can use a spray bottle or hose with a sprayer attached to it.

Use the hose to remove any pesky dirt and debris that wasn’t removed during the first cleaning

9) Remove the plastic sheeting then reassemble

10) To make sure the unit works properly, turn the thermostat to the OFF position.

11) Reset the power (the reverse of what you did when you disconnected the power)

12) Wait five minutes

13) Set the thermostat to the ON position

The unit should run for about three minutes before you check the two pipes which connect the condenser unit to the handler. Sometimes the pipes are covered by insulation. Just need to slide the insulation back to check the pipes. One of the pipes should feel cool and the other warm.

If this doesn’t work, CALL US @ (972) 365-8356. You probably did everything right. The refrigerant may require recharging.
