Why Is My AC System Overheating in Palm Harbor, FL?

With the hot and muggy weather in Palm Harbor, FL, an overheating air conditioner affects your comfort and health. It can lead to heatstroke, a higher humidity level inside and a range of other problems. Keep reading to find the most common reasons AC systems overheat.

Low Refrigerant Level

AC systems use refrigerant to keep your home cool; it transitions from a liquid to a vapor as it moves and expels the heat that turned it into a vapor outside. When the level is too low, the system may keep running without shutting down, causing it to overheat. Other signs of a low refrigerant level include ice on your outside unit and an increase in how long it takes to lower your home’s temperature.

Condenser Coils

Your AC system has an outdoor unit with a condenser coil, which is responsible for turning refrigerant into vapor. Dust and other debris can stick to the coil, causing it to run hotter and increasing your electric bills. Professional coil cleaning is the best solution.

Outdated System

No matter how much you spend on your air conditioner, most AC systems don’t last longer than 15 years. If you have one that constantly overheats and shuts down, it’s a sign you need to replace it. It usually costs less to install a new AC system than to keep repairing an old one.

Dirty/Clogged Filter

A dirty or clogged air filter limits the airflow reaching your ducts and finding its way around your home. Clogs often occur due to a buildup of skin cells, pollen, dust and any other particles in the air. Not only can the air conditioner overheat, but it may trip your circuit breaker or cause the whole AC system to break down.

Faulty Relay Switch

The relay switch sends power to your air conditioner when you turn it on and ensures the AC system receives the right amount. When the switch is faulty or broken, it can create a power surge and send too much electricity to the air conditioner.
