4 Reasons Why Your HVAC Unit is Overheating

A common problem with HVAC units arises when they work too long and too hard, resulting in overheating. Once the unit overheats, it could either trip the circuit breaker or stop working altogether.

To prevent yourself from falling victim, it would be best to acquaint yourself with the reasons that could cause the overheating. Top reasons why your HVAC unit could be overheating include a clogged air filter, dirty condenser coils, low refrigerant, and lack of professional maintenance. We shall delve deeper into these reasons and provide handy tips on how to deal with each.

1. Clogged Air Filter

The air filter is among the most vital components of your HVAC unit. When it's clogged, it could compromise indoor air quality, skyrocket the energy bill, or lead to an overheating HVAC unit. Keep in mind that air, dirt, and other particles can build up in the air filter. When you take so long before cleaning or replacing it, the build-up blocks the system's airflow. That forces your system to run for longer periods, leading to overheating.

How do you prevent your air filter from getting grimy? Replace it regularly (at least once a season). However, in some cases, you may need to replace the air filter more frequently. For instance, if you have pets or there is a large number of people in your home.

2. Dirty Condenser Coils

Condenser coils are tubes that run through your HVAC unit, filled with refrigerant. Like with a clogged air filter, dirty condenser coils will force the unit to run for longer periods to ensure you receive good-quality air. When the condenser coils are dirty, they cannot efficiently transfer heat, leading to the unit's malfunction.

While you can do the job yourself using a coil cleaner, it would be better to get a licensed technician's help. Not only will they do a more thorough job, but they can also detect any underlying problem which you would have otherwise missed.

3. Low Refrigerant

Typically, the HVAC unit is a closed-loop system. Therefore, refrigerants shouldn't escape from it in an ideal situation. However, a leak could lead to a decrease in refrigerant levels, causing warm air to blow through the vents, which results in overheating.

Contact a technician immediately you notice a refrigerant leak. Fixing a refrigerant leak requires specialized training.

4. Lack of Professional Maintenance

Your HVAC system could have underlying issues that only a professional can detect. When your unit goes for so long without professional maintenance, these problems could manifest and lead to an overheating HVAC unit.
