5 Common Air Conditioner Problems – How To Overcome?

It’s not easy for many of us to live without an air conditioner in peak summers. We have to ensure that our air conditioner remains sturdy and issue-free so it can have a long shelf-life. When we encounter minor problems in our AC that we choose to ignore, it all accumulates into affecting the performance of the AC. This will substantially decrease your AC’s longevity. On the contrary, if we keep tabs on the performance and make no delay in repairing them, the air conditioner will likely live longer. Don’t leave anything to chance.

Issues not only occur with the heating/cooling system; they’ll often be because of ventilation, performance, electricity, lack of overvoltage protection, and other factors. If you want an overworked AC to continue working for as long as possible, fix all issues before it becomes a big problem. Fortunately for you, this article will address all you need to know about the most common air conditioner problems and how to fix them.

Common Air Conditioner Problems

Common Air Conditioner Problems

1. Uneven Cooling

If you’ve faced a situation where one of your rooms is extremely cold while another room is not affected by the AC in the least, then you may be experiencing an issue with uneven cooling. This is typically due to blocked vents, poor insulation, or improper sealants. To overcome this, start by finding the underlying problem. You may have to resort to calling an air conditioning technician for repair services. Furthermore, if the problem persists or you just want one room to be cooler, try switching to zoned cooling or separate thermostats.

2. AC blowing Warm Air

The last thing anyone would want in summer is to have an AC dispense hot air when you’re anticipating a cool breeze. Before jumping to the conclusion that your AC might be busted, confirm that your thermostat settings were not accidentally changed. Second, change your air filters. Clogged air filters may be the cause of frozen coils in ACs. Another potential problem can be that you are low on refrigerant. Test this by examining the larger of the two copper lines that go into the unit’s condenser and feel them to determine whether the coils are moist or cold. If that is the case, your levels are good. If not, get a technician to refill or repair the refrigerant reservoir.

3. Frost Inside The AC Unit

Two issues could be causing frosting on the inside of a central AC unit: reduced or weak airflow over the evaporator coil or low refrigerant. This has a notably simpler solution where you can turn off the unit and allow it to defrost. Then change your filter if it’s dirty. Finally, call a professional so they can manage the low refrigerant issue.

4. A Leaky Unit

It is normal for an air conditioner to release a small amount of fluid and condensate. However, if you’re experiencing excessive leaks, then that may mean several different problems. It’s possible that the condensate line is clogged, and unclogging it is rudimentary enough to repair it on your own. This is as long as you follow the manufacturer’s directions. This is a fairly common problem in properties with multi-family complexes. Lines and pipes end up getting clogged with mold and debris. If pieces of the unit are broken, or you cannot find a manual, the best course of action to take is to call a professional.

5. Loud AC

A loud AC is an obvious issue. If the AC sounds like it is struggling to function because of the loud noises it makes, then it’s exactly how it sounds. A failing air conditioner will make different noises, making it hard to identify the exact problem. For instance, a screeching and squealing sound could mean there’s a faulty belt. Rattling sounds may indicate problems with the fans, compressor, or motors. Start by checking your thermostat and clearing all debris around the outdoor unit, then change the filters. Finally, call a professional to fix the problem.

In conclusion


There are various common air condition problems that can occur but can be solved. Uneven cooling can be pretty frustrating since it results in the house experiencing two polar seasons. This is typically due to block vents and can be resolved by a technician. Another recurring problem as an AC owner is leakage. Slight leakage is not an issue to fret over, but when it gets excessive, all you have to do is unclog the condensate line with the help of the manufacturer’s directions. Your AC blowing warm air is the last thing anyone would want in the middle of July so if this problem occurs, check copper lines to determine refrigerant levels. Frosting inside an AC is either caused because of reduced/weak airflow over the evaporator coil or low refrigerant. Finally, a loud AC might mean that the cooling system is failing, so examine the thermostat, clear all debris around the outdoor unit and then call a professional.

We hope this article proves informative and helps you overcome some common air conditioner problems. Thank you for reading!
