An air conditioning unit that’s not cooling is a common issue faced by homeowners, particularly during the hot summer months. There’s nothing more frustrating than a malfunctioning AC unit when you need it most. At Texas Air Tech, we’re committed to helping you understand your AC system better. This blog post will explore common problems that might cause your AC not to cool and their potential solutions.
Common Issues and Solutions
Dirty Air Filters
One of the most common reasons an AC unit fails to cool effectively is a dirty air filter. Over time, air filters collect dust and other debris, which can block airflow and reduce the system’s efficiency.
Solution: Clean or replace your air filters regularly. The U.S. Department of Energy recommends doing this at least every two months during peak seasons.
Sometimes, the problem could be as simple as incorrect thermostat settings. If your thermostat is set to ‘heat’ instead of ‘cool,’ or if the temperature is set too high, your AC may not cool your home effectively.
Solution: Ensure your thermostat is set to ‘cool’ and adjust the temperature to a comfortable level. If your thermostat is not working correctly, you may need to call a professional to repair or replace it.
Low Refrigerant Levels
Your AC unit uses a refrigerant to remove heat and humidity from the air. If your system has a leak, the refrigerant level could drop, causing your AC to stop cooling.
Solution: Check for any signs of a refrigerant leak, such as ice build-up on the outside unit. If you suspect a leak, contact a professional HVAC technician immediately. Handling refrigerant requires special training and equipment.
Dirty Condenser Coils
The condenser coils in the outdoor unit of your AC system disperse heat removed from the air by expelling it outside the building. If these coils get dirty, the system won’t work efficiently, and the cooling capacity can drop.
Solution: Regularly clean your outdoor unit and ensure it is free from debris. If your condenser coils are significantly dirty, you may need to have them cleaned by a professional.
If there are leaks in your ductwork, cool air could be escaping into your attic or crawl spaces instead of circulating through your home.
Solution: Inspect your ductwork for any signs of damage or disconnects. Sealing your ducts may require professional help.
Understanding common issues that can cause your AC not to cool effectively is the first step towards resolving the problem. Regular maintenance and prompt attention to potential problems can help keep your AC running smoothly.
