If you live in Texas, you probably use an air conditioner to keep cool during summer. If your AC is not cooling as it should, it’s time to take action. Here are six common reasons why your AC is not functioning properly and a few things you can do to troubleshoot the issue.

1. Low Refrigerant Level

Checking the coolant levels in your AC unit is an important part of routine maintenance. If the coolant levels are low, it could be the reason your AC is not working properly. You can purchase coolant at most hardware stores. Follow the instructions on the package to add it to your AC unit.

To check the coolant levels, locate the outdoor unit of your AC and look for a small removable panel. This panel will likely have screws holding it in place. Remove the screws and open the panel to access the coolant levels. If the coolant levels are good and your AC still isn’t working, you may need to call a professional for help.

2. Incorrect Setting of the Thermostat

The thermostat controls the temperature of your home. Ensure the thermostat is set to “cool” and the temperature is set to your desired level. If you have an older model thermostat, it may need to be replaced. Newer models are more accurate, and some are programmable to save you money on your energy bill.

3. Thermostat Sensor Problems

The thermostat sensor measures the temperature of the air and instructs the AC unit when to turn on and off. If the sensor is not working properly, it can cause your AC unit to malfunction. If the temperature is set correctly but the house is warmer than it should be, you may need to replace the sensor.

Replacing the sensor is a job for professionals. If you live in Cypress, TX, you can engage a certified technician from AirDepot to diagnose and fix your AC problems quickly. We may also be able to offer tips on how to prevent future problems.

4. Clogged Drainage Line

If the drainage line becomes clogged, water will back into your AC unit and cause it to shut down. To check, locate the outdoor unit of your AC and look for the drainage line. This is usually a white PVC pipe that goes from the unit to a drain or an underground pipe. The drainage line is probably clogged if you see water around the unit or notice that the ground is wet.

To clean the drainage line, remove any debris that may be blocking it, disconnect it from the AC unit and then flush the line with water to clear any remaining dirt or grime. If you sign up for our maintenance plan, checking and cleaning drain lines is part of our regular service.

5. Fan Problems

The fan is an important part of your AC unit. It helps circulate the air and keeps the unit cool. The indoor and outdoor fans must work properly for your AC unit to function correctly. If either fan is not working, it could be the reason your AC is not cooling. Check both fans and ensure they are free of debris.

If the fan is not working properly, it could be due to several issues, such as a loose belt or dirt and debris buildup. You can clean the fans with a soft brush if the fans are dirty. You can also check the manufacturer’s instructions on how to clean or replace the fan. You may need to call a professional for help if the problem persists.

6. Dirty Air Filter

A dirty air filter can restrict airflow and cause your AC unit to work harder than necessary. It’s a good idea to check the air filter monthly and replace it every three months or as needed. A new air filter will help improve the efficiency of your AC unit and keep your home’s air clean. If you have pets or live in a dusty area, you may need to replace the air filter more often. Check the manufacturer’s recommendations for how often to replace the air filter.
