4 Reasons Why Your HVAC Unit is Overheating

When your air conditioner or furnace overheats, it runs for a few minutes then trips the circuit breaker. Unfortunately, the system will continue tripping the circuit breaker until you fix the overheating problem. No one wants an overheating HVAC system; however, it is common, especially during summer. Here are four common causes of overheating in HVAC systems.

Dirty Condenser Coils

The outdoor unit of your HVAC system is known as the condenser. Condenser coils are tubes that run through the condenser, and they are filled with refrigerant. The coils collect heat from the inside of your home and release it into the outside air. These heat-dissipating coils can get very dirty, and when this happens, the coils will not release all the heat they have collected because of the grime that is caked onto the coils. Thus, to achieve your desired temperature, the HVAC system will have to work extra hard, which can cause your HVAC unit to overheat.

Your Unit is Old

The average lifespan of an HVAC system is between 15 to 20 years. Although a properly installed HVAC will last long, it won't last eternally. Also, older HVAC systems' models don't have the same features and upgrades as the newer ones. Thus, it is crucial to know the model and age of your HVAC unit. As it reaches the end of its life span, its components may wear out, causing it to overheat. So, consider replacing your HVAC unit if it has been operating for over a decade.

Low Refrigerant Levels

If your air conditioner has insufficient refrigerant, it cannot cool down your home effectively or quickly since it needs a sufficient amount of refrigerant to transfer the heat from your home. So your AC will need to work extensively and harder to keep your home cool, and that can make several components to overheat.

Clogged Air Filter

The air filter in your HVAC system prevents dust and debris from entering the system and making its components inefficient. However, if the air filter becomes excessively filled with dust and airborne particles, it will prevent an ample amount of airflow through your HVAC system. And when the heating and cooling system lacks adequate airflow, its components must work harder to regulate the air in your home. This puts a strain on your HVAC system and causes it to overheat, trip the circuit breaker, or break down. Thus, check your air filter monthly to make sure it is not packed with dirt and debris. As a homeowner, the easiest way to protect your air conditioner from overheating is changing your air filter every month and scheduling a tune-up for your HVAC system before every cooling season. Maintaining a fresh filter will prevent problems related to the buildup of dirt and dust in your HVAC system, and a tune-up will help you check for all the issues listed above and many more.
