HVAC Service Necessary? Common A/C Problems That Sideline Your Cooling System

HVAC Service Necessary? Common A/C Problems That Sideline Your Cooling SystemRegular HVAC service helps prevent many common air conditioner problems, but going too long without maintenance can spell trouble. If you’d rather not be left without your A/C in the middle of a Fort Worth/Arlington-area summer, watch for signs of these common problems.

Refrigerant leaks
— For optimal efficiency, your system’s refrigerant charge should be exactly what the manufacturer stipulates. Loss of refrigerant through leaks reduces your system’s efficiency and can cause the evaporator coil to freeze or the compressor to fail early. Leaks may occur due to incorrect installation of the copper tubing, manufacturing issues or pin-hole leaks in the walls of the tubing. A technician can find and repair leaks, recharge your system with refrigerant, then test the repairs.

Blocked condensate drain — Humid Texas weather and lack of maintenance can lead to a buildup of sludge that clogs your condensate drain. When this happens, backed-up condensate (water) may overflow and cause water damage or your whole system may shut off. A technician can use a condensate drain brush or other tool to clear the blockage. If your drain clogs frequently, it may have been incorrectly installed, a problem a skilled technician can correct.

Thermostat issues — If your thermostat is set too high, your A/C won’t kick on. Try lowering the thermostat five to 10 degrees and waiting a few minutes. Dirt buildup is another potential problem because it can affect the thermostat’s calibration, causing it to misread the room temperature. Knocking the thermostat out of alignment can also cause misreadings. An HVAC service technician can resolve these issues for you.

Electric control failure
– Over time, electrical wires and terminals can work loose or become corroded and line voltage may change. During regular HVAC service, a technician can identify and correct these issues before they cause problems with your compressor and fan controls.

Insufficient maintenance
— Changing your filters as needed keeps your system running efficiently and prevents excess wear on the motor. Other system components also need regular cleaning to run well. A dirty condenser or evaporator coil can cause your system to run without providing cooling. Too-frequent cycling is another problem a dirty evaporator can cause.
