Here’s How to Solve These 5 Common Air Conditioning Problems


When the weather gets a bit too warm, there’s nothing more frustrating than when your air conditioner runs into a problem. Fortunately, there are a few common issues that can be easily identified and fixed without needing to call in a professional. Here are some popular air conditioning problems, as well as you can fix them yourself.

Air Conditioner Won’t Start

When your AC unit just won’t switch on, the first thing you should do is check the power source and make sure that it’s plugged in properly. If that doesn’t do the trick, you should also examine the circuit breaker or fuse to ensure that neither has been tripped or blown. Finally, you can also check your thermostat and make sure that it’s configured for cooling mode and set to the desired temperature for effective room cooling.

Air Conditioner Doesn’t Cool Effectively

Multiple factors can lead to your air conditioner running but failing to adequately and uniformly cool your space. The most prevalent cause of this problem is a clogged or dirty air filter, as blockages within the filter can significantly compromise the airflow and circulation within the unit, preventing it from lowering and cooling of the air.

Another potential issue might stem from an obstruction within the outdoor unit of your cooling system. Therefore, it’s essential to ensure that the unit is free from any impediments such as leaves, branches, or dirt, which could restrict the airflow.

The Air Conditioner Cycles On and Off Repeatedly

This problem could be attributed to a dirty or obstructed condenser unit or evaporator coil, which can prevent heat transfer and result in the system cycling on and off more frequently. Another possible cause is that you’ve chosen an air conditioner with too high of a cooling capacity for the space that it was placed in.

Cooling capacity assesses how effectively and efficiently a unit can lower room temperature, but there is the misconception that higher capacity is always better. An excessively high cooling capacity can cool the space too rapidly, placing undue stress on the system and causing discomfort for occupants. This may cause the unit to cycle more frequently in an attempt to maintain the desired temperature.

The Air Conditioner is Making Unusual Sounds

Hearing unfamiliar sounds coming from your air conditioner can be disconcerting. The initial step is to identify the specific noise, as it can provide valuable clues about the underlying issue. A grinding noise may signal problems with the unit’s motor or bearings, while a squealing sound could indicate a worn-out belt or fan motor. On the other hand, loud banging sounds may result from loose components within the unit.

Air Conditioner Water Leakage

This problem is quite prevalent and is likely attributed to a blocked condensate drain line or a damaged condensate pan, which collects the water generated by the unit during the cooling cycle. You can inspect the condensate pan for any cracks that might be responsible for the leakage, or attempt to clear the drain line using a wet and dry vacuum cleaner.
