In highly humid areas, people are more likely to use their air conditioners longer and more often. The air conditioner’s sole purpose is to draw out damp, hot air and enjoy cool breezes, but you will likely need to learn its adverse effects on the AC.

Understanding these reasons can help maintain your AC and ensure the best performance, especially in humid regions. 

So, today, we will answer a very demanding question about your AC units;

Does Humidity Strain My Air Conditioning Unit? Let’s find out!

Five Major Reasons How Humidity Strains Your AC

1. Increased Work Load: 

High humidity levels make the air feel warm, and the unit works harder and more often to maintain the low temperatures you desire; this frequent load and heavy burden on your unit can negatively impact its optimal performance.

The best solution to this problem is to use a dehumidifier, which will help decrease excessive moisture in your indoor environment, relieving the unit’s workload.

2. Reduced Efficiency 

High humidity levels cause your unit to strain and reduce its efficiency over time. In humid areas, when the unit is forced to work harder and remove excessive moisture from the air as well as blow cool breezes for you to enjoy, the unit gets a lot of negative impact on its different parts because of the heavy workload, hence disturbing the long term efficiency of your unit.

Maintaining and cleaning your unit’s filters and coils is the best solution. However, hiring a professional company like SurfSide, which can provide a thorough and complete AC cleaning service, is much better.

3. Frozen Evaporator Coils

When your unit is overburdened with heavy loads to save your back in such hot and humid weather, it is likely to disturb the cooling efficiency and increase the risk of damaging the compressor, which you probably do not want it to be. Right?

The best solution is to check and clean the vents and filters, ensuring good airflow. Checking refrigerant levels is also necessary to some extent in such cases. 

4. Inconsistent Cooling 

High humidity levels can cause your AC unit to struggle with uneven cooling. Sometimes, you might feel slightly uneven about your AC unit’s cooling. Make sure to check if your AC unit is appropriately sized according to your house’s needs.

The best possible solution for this problem is to seal any remaining ductwork and ensure proper insulation. However, you might have bought an oversized AC unit, which causes these complexities, so moving to a smaller unit is better.

5. The strain on Components 

The additional workload caused by excessive humidity can sometimes be a huge and expensive problem because it might strain any of your units’ costly and essential components, such as Compressors, fans, or even motors. This can cause frequent breakdowns and a little money-making opportunity for those cheeky businesses.

Solution: I recommend you guys regularly ( Once every 2-3 weeks ) inspect and service your AC components to ensure they are in good working condition and would not cause any surprise by breakdown on some of the hottest days.


That’s it all for today, guys. The major problems and solutions are appropriately explained in today’s blog. I hope that you guys don’t have to face any expensive fancy works that might cost you hundreds of bucks, So make sure to inspect and service your AC unit frequently in the sunny weather, atleast so that it might not break with a surprise in the middle of a hot day.

Also, check out SurfSide.services, which might be my bonus tip. They are one of the best AC repair and servicing companies in Mobile and Baldwin counties.
