Find Out Whether Your AC Needs An Emergency Repair

Posted on

When on the verge of summer, you require your AC to be in good working condition to combat the heat. However, if your AC suddenly gives out, it can leave you sweltering indoors on warm days. Therefore, it is vital to understand the signs that your AC will exhibit to warrant a repair by an AC expert before it breaks down. Below are four signs that your home requires emergency AC system repair.

Unusual Noises

Typically, an AC makes relatively low noises during operation due to the running compressor, air flowing through the ducts, and sudden pressure fluctuations when the unit starts up and shuts down. However, when your AC produces loud and strange noises, it likely indicates an underlying problem. For example, a shrieking noise may indicate a defective fan motor, while a humming noise signifies a faulty contactor relay switch. Since unusually loud noises point to a specific system malfunction, it is imperative that an AC technician diagnose your unit. Then, they accurately determine the defective components and repair them for optimal functionality.

Vents Blowing Warm Air

There are numerous causes of this issue. To begin with, your AC could be running low on the refrigerant. Alternatively, the problem could be a faulty compressor or blocked airflow. On the other hand, since the refrigerant circulates in a closed loop in lines carrying it as it absorbs and emits heat outdoors, in case the coolant lines develop a leak, the refrigerant depletes gradually, impeding the heat exchange process.

Short Cycling

An AC runs in cycles to achieve your thermostat setting. However, if your system frequently turns on and off without completing a full cycle, it will stop the compressor prematurely, causing it to sustain more wear and tear. In addition to a clogged filter causing short cycling, an oversized AC unit cools the room too fast, causing the unit to short cycle. Therefore, you should contact an AC specialist to clean the filters regularly and ensure that your appliance has optimal cooling capacity.

Excessive Humidity

Your unit cools the air as it simultaneously dehumidifies it. Therefore, if you notice that your room is stuffy while still sweating, your system could be the victim of higher-than-usual humidity. Dirty evaporator coils, for instance, may impede heat transfer, causing moisture retention in the air as it passes without being drained as a condensate. Additionally, an oversized unit short-cycles without adequately removing moisture from the house.

Fortunately, an AC will usually show indications of a system malfunction before it breaks down. Accordingly, you should contact an AC contractor to attend to your system, repair it, and address underlying issues.
