According to research, the warmest summer in 122 years occurred in March 2022. The temperature is becoming unpleasant, particularly during the summer. Because it is one of the best ways to escape the blistering heat, the air conditioner has become an unavoidable feature of every household.

However, once your Goodman air conditioners is placed in your home, the next major air conditioner issue is proper cooling. When looking for a good air conditioner, one of the most important factors to consider is the cooling capacity. Some reasons why your air conditioner could not be cooling properly are listed below:

Filter is Clogged

After lengthy use of the air conditioner, the air passes through an air filter, which decontaminates certain dangerous compounds that may be present in the air outdoors. The clogging of this air filter with various substances could be the cause of the air conditioner not cooling. This problem can be rectified by simply cleaning the blocked air filter or, if the filter is old, replacing it.

Inadequate Coolant

The coolant is a solvent that circulates inside the evaporator coil and helps to cool the air passing through it. However, with regular use, the amount of coolant in their air conditioner may decrease, or it may freeze owing to infrequent use.
The proper operation of an air conditioner needs the usage of a specified volume of coolant. As a result, have a qualified individual check the coolant level in your air conditioner and get it replaced as soon as possible.

Temperature Changes in the Atmosphere

The correct operation of an air conditioner necessitates a specific room temperature. Because the weather is unpredictable, swings in ambient temperature above the AC’s ideal temperature can cause the compressor to shut down completely due to a lack of dependable signals.

Compressor Failure

The compressor is the air conditioner’s heart, and it receives a signal from the thermostat to start the cooling cycle inside the unit. In simple terms, the compressor is a motor that compresses the refrigerant and then circulates it through the evaporator and condenser coils to chill the air. The compressor must be examined first since it is the initial stage of the cooling process, and if it fails, the rest of the cooling process would be rendered useless.

AC Remote has a Flaw

It’s not always a problem with the air conditioner; it could be a malfunction in the remote caused by a leaking battery or another mechanical issue within the remote. It’s critical to have a new remote in order to provide accurate temperature signals to your air conditioner.


The thermostat controls the room temperature in the immediate proximity of the air conditioner. The thermostat detects the room temperature and tells the compressor whether or not to start or stop the cooling process. The room temperature will not be properly determined to signal the compressor if the thermostat is damaged or faulty, causing the entire process to be disturbed and the air conditioner to not cool efficiently.

Coils that are filthy

Another reason the air conditioner may not be chilly enough for the summer’s oppressive heat is if the coils are dirty. An air conditioner works on the idea of dissipating or eliminating heat from the air and condensing it to chill our environment. The condenser coil, on the other hand, must be clean in order to take heat from the air. As a result, if the coils become clogged with dirt, the air conditioner will be useless and the space will not be cooled.

Other Concerns

Even if one of the reasons listed above is the cause of your air conditioner’s failure to chill your room correctly, other problems can occur. The following are the most prevalent ones:

Rooms that are either too Little or too Big: It’s possible that the air conditioner isn’t the correct size for the space it’s in; for example, a single split air conditioner can’t cool a large dining room. As a result, you’ll need to get an air conditioner that’s the right size for your space.

Ducts that are Leaking: Even if all of the air conditioner’s mechanical components are in good operating order, the air conditioner not cooling can be a problem. Check the ducts of your air conditioner with your mechanic, since even a little leak might reduce its performance.

Proper Sealing: Cooling the air in your home demands a minimum movement of air from your room to the outside environment, so ensure sure there are no air leaks in doors or windows.
It is usually a good idea to get your Lennox air conditioners troubleshot once in a while to see if there are any problems. An air conditioner, like any other large mechanical or electrical gear, requires periodic maintenance and cleaning to perform properly.
