What Are Some of the Common AC Problems?

Because air conditioner repairs and replacements can be expensive, scheduling regular maintenance and tune-ups with experienced AC contractors is critical to enjoying the best AC performance. Understanding common air conditioning problems is critical so you can take preventive measures to avoid costly repairs.

As the weather warms up, many people find that their air conditioners are no longer working as effectively as they used to. If you’re one of those people, you’re probably wondering what might be causing the problem. 

Dirty Air Filters

One of the most common reasons for AC problems is dirty air filters. When the air filter is clogged with debris, it can restrict airflow and cause your AC to work harder than it needs to. Pet owners should be extra cautious about air filters because pet fur requires more frequent replacement. The solution is simple—replace the air filter!

Refrigerant Leaks and Thermostat Problems

Another common AC problem is a refrigerant leak. Refrigerant helps your AC unit cool the air, so if there’s a leak, it can cause your unit to run less efficiently. If you think there is a leak, it’s best to contact a professional for help.

Maybe you find your AC unit isn’t cooling the air properly. It could be because of a problem with the thermostat. The thermostat tells the AC unit when to turn on and off, so if it’s not working correctly, it can cause all sorts of problems. 

There could be a serious problem due to dust and corrosion build-up, or it could simply be a case of dead batteries. Loose screws or wires inside the thermostat can also interfere with its operation. If you place your thermostat in direct sunlight, this can also affect its reading. Another cause of your thermostat not working is incorrect calibration.

Frozen Evaporator Coil

A frozen evaporator coil could cause your air conditioner to not cool properly. A common issue with home air conditioners occurs when your unit does not receive enough air to function normally due to debris build-up.

The dirt on the coils restricts airflow, preventing warm air from reaching the refrigerant. The refrigerant becomes too cold in this case, and any moisture on the coils freezes.

The coil becomes encased in ice over time, preventing the refrigerant in the coil from absorbing latent heat. 

Capacitor Failure

When your air conditioner turns on and off for no apparent reason and you hear a clicking noise, it might mean it’s a capacitor issue. A capacitor is a component of your air conditioning unit that gives the motor the initial push it needs to start working.

When your air conditioner has to work hard in the summer heat, the capacitor can overheat. Your capacitor can also be damaged by power fluctuations and frequent changes in thermostat settings.

These are just some of the most common AC problems. If you’re having trouble with your AC unit, one of these is the culprit. But if you’re unsure, or need help fixing the problem, don’t hesitate to call a professional! At KC’s Plumbing, we are experts in AC Installation in Palm Springs, California.
