Common Causes of AC Malfunctions

With summer in full swing, your air conditioner works tirelessly to keep you cool. However, occasional malfunctions can hinder its performance, leaving you searching for cooling relief. AC malfunction can be frustrating, especially during peak summer heat. When your air conditioning goes out, schedule a service call with a professional to fix the problem. But before you call, it's good to know some air conditioning basics and common causes of AC malfunctions. 

Clogged Air Filters

Dirty air filters are the leading cause of AC malfunction. Clogged filters prevent cool air from circulating throughout your home, forcing your AC unit to work harder to maintain the desired temperature. As a result, the compressor may overheat, causing the AC to shut down. To prevent this, replace your filter at least once during summer.

Refrigerant Leaks

Refrigerant plays a crucial role in cooling your home. If there's a refrigerant leak, your AC will fail to perform efficiently. Common signs of a refrigerant leak include warm air coming from your vents, frozen coils, and strange noises. If you suspect a refrigerant leak, call an HVAC professional immediately.

A Malfunctioning Thermostat

The thermostat is the brain of your AC unit. It tells the AC when to turn on and off, maintain the desired temperature, and control fan speed. If the thermostat malfunctions, the AC will not work properly. To ensure that your AC unit is working correctly, replace your old thermostat with a programmable or smart thermostat.

Dirty Condenser Coils

Condenser coils transfer heat from inside to outside of your home. If your outdoor unit is clogged with debris like leaves, grass clippings, or dirt, your AC may not work correctly. Clean the condenser coils regularly and remove debris surrounding the unit to allow proper airflow.

Lack of Maintenance

A lack of maintenance is another common cause of AC malfunction. Regular maintenance is crucial in keeping your AC unit running smoothly. An HVAC professional should inspect your AC at least once a year before summer. They will check the unit for issues, clean the condenser coils, test the refrigerant levels, and replace worn-out parts.

Knowing the common causes of AC malfunctions can help you prevent them. Keep your filters, condenser coils, and indoor and outdoor units clean, and replace your thermostat with a smart one. Regular maintenance will ensure that your AC unit is working smoothly and efficiently and will keep you cool during the summer months. If you notice any issues, don't hesitate to call an HVAC professional immediately to repair your system.

When we bought our house, we had a home warranty that was good for one year. One of the first things that had to get taken care of was the air conditioner. Before we had the HVAC contractor come out, we made sure filters were changed and other basic maintenance was taken care of. The HVAC contractor that the insurance company sent out replaced the compressor and our AC is working fine now so we're glad that we did it when we did, especially because he found a major mistake in our system. You don't want to wait long when the AC goes out on a hot summer day. This blog is here to make sure you get the help you need.
