An Effective Air Conditioning Repair Guide for Dealing with Common AC Problems

Summer temperatures can reach into triple digits on the East Coast, making it nearly impossible to cool off if your AC unit isn’t working properly. Although there are a number of reasons why your AC unit may malfunction, following are several fairly common ones warranting your awareness.

Low Refrigerant

The refrigerant in your unit is what cools the air, which then circulates into your home. When it gets too low, your home can no longer stay cool. There are several signs to look for regarding low refrigerant (coolant). Warm air may come through the air ducts, for example. Or, the AC unit may produce cool air at night, but warm air during the day. Also, your electric bills may rise above their average amount.

More problematic, your refrigerant might leak. Leaks need to be identified and assessed by licensed HVAC technicians who deal with air conditioning repair. Almost all technicians are constantly equipped with an electronic leak detector when summoned to fix a problem. Professionals can also conduct a nitrogen-leak-detection test, which incorporates audio or sound to identify this type of leak, as nitrogen is kept at a much higher pressure than coolants such as freon.

It’s also important to let professionals replace coolant that contains CFCs, a refrigerant banned in 1995 due to its effect on the environment.

A Frozen Evaporator Coil

When your evaporator coil freezes, your AC unit can’t produce cool enough air and is forced to work harder. This can happen for several reasons, including a restriction of air and insufficient refrigerant.

If this happens to your coils, the first thing you should do is shut off the AC unit. Check to make sure the air filter and air-duct system are clean. Open all of the registers to ensure that airflow is not restricted.

If freezing is still an issue, contact a qualified technician who will diagnose the problem and provide tips to help you avoid similar issues in the future.

Sensor Problems

Every unit features an AC thermostat sensor, which is designed to measure the temperature of air coming into the evaporator coil. If this sensor gets knocked out of position, the unit may cycle randomly and drive up your energy bills. It is therefore important to make sure your sensor is placed near the coil, but not touching it. Adjust the sensor’s position until it’s stable and unwavering.
