AIR PROS - Why is My AC Unit Blowing Hot Air_

There is nothing like a perfectly working air conditioning unit in a warm climate like Hollywood, FL. However, there are times when the AC develops issues that require repair from an AC service tech in Hollywood, FL. At Air Pros, we pride ourselves on providing the top education and knowledge required to our clients that is required to understand how the HVAC system works. In this article, we will discuss why an HVAC unit would blow warm air. 

Reasons Why the HVAC Unit is Blowing Warm Air

There are many reasons for why an AC unit produces warm air. These reasons all boil down to a common theme: proper AC maintenance. In order to extend the lifespan of your HVAC, there are certain maintenance steps that one must take to do so. Read on to learn what causes warm air to come from an AC unit. 

Clogged Air Filters

Clogged air filters are one of the leading causes of an HVAC unit blowing warm air. Air filters are the last  components that the air travels through to enter the home. With time, they accumulate dust and debris that traps the air. This prevents proper air circulation and will cause the unit to overheat, decreasing the lifespan of the unit. 

To avoid this problem, ensure that your air filters are cleaned regularly. We recommend adding this task on your list of monthly chores in order to prevent a clog. This small step will help maintain optimal cooling efficiency of your home.  

Dirty Evaporator Coils 

If your HVAC unit is blowing warm air, chances are that the coils in the condenser unit are dirty. As the unit works to cool your home, it accumulates debris, dust, grime, and mineral deposits that have to be cleaned out periodically. 

If the coils aren’t cleaned, the buildup will eventually lead to a blockage that will prevent the compressor from expelling the heat out of the outdoor unit. This will cause the unit to overheat and produce hot air instead of cooling the home. 

Poorly Functioning Air Compressor

A poorly functioning air compressor is hard to diagnose without an AC service repair in Hollywood, FL. However if the compressor isn’t working well, it will affect the rest of the unit. A dysfunctional AC compressor frequently has trouble releasing the heat out of the unit for a variety of reasons. The buildup of hot air will cause the compressor to overheat and cause the AC to blow out hot air. 

Your HVAC unit blowing warm air is just one of the reasons for replacing the AC compressor. Check out our blog to learn about what other problems will require this replacement. 

Problems With Refrigerant Lines

The refrigerant lines of your AC unit transport refrigerant fluid throughout the unit during the heat exchange process. Much like the evaporator coils, they too develop grime and debris that lead to a blockage. This blockage can prevent the proper circulation of refrigerant fluid that cools the warm air. When this blockage occurs, the warm air will not be cooled appropriately. 

Sometimes, there are refrigerant fluid leaks that require AC service repair in Hollywood, FL. With a present leakage, the ACcompressor will not have enough power to push the heat outside of the unit. This will decrease the unit’s efficiency and abilities to cool the home. 

Blow Motor Malfunction

The blow motor is the part of the AC that blows cooled off air into the air ducts. If it becomes overheated, it will cause the cooled off air to warm up. This will lead to the unit working harder and the overall efficiency will go down, leading to an HVAC unit blowing warm air. 

This problem will need to be properly inspected by an AC service tech in Hollywood, FL. An overheating blow motor can lead to it catching on fire and even more hazardous events. 

Pay close attention to the smell your AC produces. If you smell burning, that means the blow motor is on fire. At that point, the AC will need to be shut down immediately and an emergency AC tech will need to be called for assistance. 

The blow motor is an integral part of your HVAC unit. Learn about the signs that indicate a need for a new HVAC blower
