Common Reasons Why Your AC Unit Might Need Repair

Air conditioning units are essential for ensuring comfortable temperatures inside your home during hot summer days. However, AC problems can arise unexpectedly and disrupt your daily life. To prevent issues from becoming more serious, you need to identify persistent AC issues and address them quickly.

Here are a few of the most common reasons why your AC unit may need repair.

Clogged Air Filter

Clogged air filters are a common issue that can cause one's AC unit to malfunction or need repair. These filters are typically located near the blower fan of an air conditioner and serve to keep dust, dirt, and other contaminants from entering the system.

Over time, these filters can become clogged with debris, preventing the fan from drawing in enough air to allow the proper functioning of the AC unit. A clogged filter can also prevent cold air from entering the interior of a building or home, leading to higher energy bills and reduced efficiency.

To determine if your AC unit is having trouble due to a clogged filter, you should first check for signs that could indicate a blockage. Look for any visible signs of dirt on the filter itself and inspect for any unusual noises from your AC unit, such as humming or rattling. If you have noticed either of these indicators, consult a professional who can safely assess whether or not your filter needs cleaning or replacement.

When replacing an air filter, take note of the size required for your AC unit to function properly. Many homeowners make the mistake of purchasing filters that are incorrectly sized, resulting in airflow problems that could potentially damage their equipment and require costly repairs down the line. 

When replacing an air filter, it is best practice to refer to your owner's manual or contact a qualified technician for assistance if needed.

Faulty Thermostat

Faulty thermostats can be a major cause of AC unit repair needs. A thermostat is a mechanism that controls the temperature in your home or building, and when it is not functioning properly, your AC unit may suffer. 

Some signs of a malfunctioning thermostat include inaccurate readings on display, lack of response when buttons are pressed, or the air conditioner cycling off and on too frequently. If any of these issues arise while using your AC unit, then it is likely time to repair your thermostat.

When assessing why an AC unit requires repair due to a faulty thermostat, there are several causes to consider. Firstly, if the device was not installed correctly by a qualified technician, it could lead to airflow issues that could grossly affect its functioning. There may also be problems with wiring connections between the device and the main panel, which can cause improper operation.

If your AC unit might require repair due to a faulty thermostat, contact an air conditioning repair professional to diagnose the issue and provide a solution. If a simple cleaning and reset do not fix the problem, then the thermostat may need to be replaced entirely.

Troubleshooting HVAC Issues

About a year ago, I realized that our air conditioner just wasn't cutting it. Our home was constantly hot and humid, even though our air conditioner was running almost all the time. In addition to driving up our energy bill, my entire family was tired of sweating constantly. To resolve the problem, we decided to hire an HVAC contractor to come out and fix the problem. He figured out that our compressor was damaged, and he replaced it for us. After that, our system ran great again.
