Air Conditioner Overheating in Horizon, TX

Why Is My Air Conditioner Overheating in Horizon, TX ?

September 27, 2022

One of the most common issues, when the weather warms up, is an air conditioner that overheats. Not only is this a major inconvenience, but it can also be a sign of a more serious problem. Here are several common reasons why your Horizon, TX home air conditioner is overheating.

1. Dirty Air Filters

Air filters prevent dirt and dust from entering your AC unit and clogging up the system. When the filter becomes clogged, it restricts airflow and causes your unit to overwork itself and overheat. To avoid this, make sure to check your air filter monthly and replace it as needed.

2. Low Refrigerant Levels

Refrigerant helps your AC unit cool and dehumidify the air in your home by absorbing heat from inside your home and releasing it outside. If there’s a leak in your unit’s refrigerant line, it will cause the unit to overheat. You’ll need a professional to recharge your system with refrigerant if this is the case.

3. Blocked Airflow

When airflow becomes restricted, it causes your AC unit to work harder than usual, which makes it more likely to overheat. There are a few things that can cause airflow blockage, including debris around the unit, a dirty evaporator coil, or closed vents in your home. To prevent this from happening, make sure to clear debris around your AC unit every month and keep the vents in your home open.

4. Faulty Thermal Limit Switch

The thermal limit switch is a safety device that turns off your air conditioning unit when it starts to overheat. If this switch is faulty, it won’t turn off the unit when it starts to overheat, which can cause permanent damage to your AC unit. You will need to hire a professional AC repair person to take a look at it.
