Common AC Problems and How to Fix Them

ac repairAir conditioning is essential during the hot summer, especially in South Jersey. With high humidity levels and temperatures often exceeding 90 degrees, life can feel unbearable with a malfunctioning AC unit. Repairs or a breakdown can be costly and inconvenient, so ensure your air conditioner is always in tip-top condition with regular maintenance. At Clay’s, we believe it’s a good idea to be prepared for the unexpected. That’s why we’re sharing some common problems and the best AC troubleshooting tips on how to fix them. 

Dirty or clogged filters

One of the most common AC issues is dirty or clogged filters. Dirty filters restrict airflow, causing your AC to work harder and consume more energy. To fix this problem, clean or replace the filter every couple of months or according to the manufacturer’s recommendation.

No airflow

If you don’t feel any cool air coming from your vents, it’s typically an easy problem to fix. Sometimes it’s as simple as a tripped circuit breaker, while other times, you might want to call a professional HVAC contractor to replace the blower belt. 

Malfunctioning thermostat

A faulty or malfunctioning thermostat could be the cause of your AC problems. A malfunctioning thermostat could prevent your AC from maintaining the desired temperature or turning on. Before you call a technician, check to see if your thermostat setting is on “cool.” If the issue persists, you may need to replace the thermostat.

Strange noises

Banging, screeching, or rattling sounds coming from your AC are typically signs it’s struggling to keep your home cool. Failing air conditioners make different noises that can be difficult to diagnose. Squealing or screeching sounds could mean there’s a problem with the belt. Rattling sounds are associated with fan, motor, or compressor issues. Beyond checking your thermostat, clearing debris from your unit, and changing your filter, it may be time to call an HVAC contractor to fix the problem. 

Frozen evaporator coils

Your AC’s evaporator coils absorb heat from the air to cool it down. However, if there’s inadequate airflow or a low refrigerant level, these coils can freeze up and stop functioning correctly. To fix this issue, ensure sufficient air flows around the evaporator coils by checking for blocked vents or ducts. If freezing continues, contact an HVAC professional for additional help.

Short cycling

Short cycling is when your AC unit continuously turns on and off in short intervals without adequately cooling your home. This issue not only reduces the efficiency of your system but can also lead to increased energy bills. There are several possible causes for short cycling, such as an oversized AC unit, a clogged air filter, low refrigerant levels, or obstructions like debris or leaves around your unit. 

Leaks and moisture

While your HVAC system creates some moisture, excessive leaking or pooling water is a problem. Most commonly, the condensate line becomes clogged and needs to be cleared, which is a quick fix. If you notice brightly colored stains near your AC, turn off your unit and call a technician immediately. Refrigerant leaks can damage the compressor, which can be extremely expensive.
