Avoid These Common AC Unit Problems with Proper Maintenance


A broken AC is not something you would like to have, especially during the hot summer season. However, if you’re not properly taking care of it and not scheduling it for checkup and maintenance, then do not be surprised if your unit breaks down any time soon. 

In the summertime, homeowners mostly overuse the AC, and sometimes because of the non-stop use and excessive heat, the unit would work harder than they usually do. 

That is why we will never get tired of reminding you to schedule your regular unit check-up and tune-up. If you remain consistent with those, here are some problems that you could avoid:

AC Unit Breakdown

The worst thing that you can get is the entire unit breaking down. Unfortunately, the only way to solve your problem is to get a new one. Sometimes, it is due to the unit’s inefficiency or the need to face expensive and repetitive repairs each time. Getting frequent breakdowns is also another sign that it would be best to spend on a new one instead of having the same problem over and over again.

The Minor AC Breakdown

If you have been using your unit for a while now and you did not bother to have it checked once in a while, your AC could also experience minor breakdown incidents. This problem usually occurs when the airflow in the unit is restricted in some ways. It could be due to blocked vents, clogged filters, leaky ducts, and the like, which could have been prevented should you have scheduled your regular cleaning and maintenance.

The Coolant Needs to Be Replenished

Without regular maintenance, you would not know the current condition of your AC’s coolant. The coolant is the liquid that enables your system to cool down the air that comes inside it. That is how you get cold air when you turn on your AC. This coolant is meant to be replenished every now and then. However, the lack of coolant could also take place because of a leak in your unit. When leakage is indeed the problem, refilling the refrigerant is not enough to solve your unit problem.  

You Get Low Quality of Air 

The air quality that your AC unit blows off into your home also depends on how well it is taken care of. Even if you are not using your AC unit during wintertime, the wind still blows, and they carry a lot of allergens, dust, and debris that could get stuck on the fans and coils of your unit. You need to have your unit cleaned first before you run it again during the summertime. 

The filter also affects the quality of the air your unit produces. When it is not replaced every three months, the same thing will happen. Dust, dirt, and pollen would accumulate in these fillers, and they could be blown off around the house, becoming part of the air that you breathe.

Shorter Life Span 

If not maintained well, your AC unit would not function appropriately and would have a hard time performing its duties. Instead of lasting for more than 10 years, it might experience regular breakdowns that could affect its lifespan. 


During the summer season, the last thing you would want is to have a broken AC. Keep this in mind throughout the year and schedule regular maintenance to check how it is performing. Maintenance does not need to happen every month; twice a year is already enough. By doing this, you lessen the risk of your unit not performing as it should.
