Reasons Why Your Air Conditioner Isn’t Cooling Your Home

Is your home still heating up even though your air conditioner is running? The heat and stuffiness can be frustrating, and at some point, you may even want to consider opening the doors and windows instead of relying on your faulty AC.

While the unexpected temperature rise may be a key indication that your AC is due for an air conditioning repair service, There may be other factors that contribute to inefficient home cooling.

This article will run you through the possible reasons why your air conditioner is not cooling your home properly.

Warm Air Is Leaking In

If your AC is not cooling your home properly, it is possible that warm air is leaking into your home from other areas. This is particularly common in older drafty homes. You may need to check your windows and doors.

Leaky Air Ducts

Air ducts carry the chilled air into your home. If you have leaky air ducts, the cool air may not be getting to each vent as it is leaking before it reaches the room.

The Wrong AC Unit Size

Your air conditioner is designed to cool a certain number of your square feet, depending on its capacity. Are you sure your AC unit size fits your home space requirements? 

Closed Vents

Your vents allow warm air to leave the room. If your ducts are blocked or closed, they may restrict the movement of air into your home and allow warm air to flow into your home through other vents. Your air conditioner will have to work overtime to compensate for the warmer air.

If you notice that your air conditioning vents are clogged with dirt or dust, you should clean them or arrange a service.

Lacking Refrigerant

Air conditioning systems use refrigerants to cool the air. Your AC needs a certain amount of refrigerant to cool air. If your system is low on refrigerant, due to a leak, your air conditioner will not be able to cool your home effectively.

A Dirty Condenser

The condenser is the area of the air conditioning unit where the air passes through to get cooled. If your condenser is dirty, it may not be able to do its job effectively. The rest of your unit will compensate for this inefficiency and wear down your air conditioning system.

A Dirty Air Filter

The air filter allows clean air to enter your air conditioning unit. It blocks any dust, debris, and pollen that can contaminate the air and block your unit.

A dirty, clogged air filter can indeed affect your air conditioner’s performance. The less airflow, the harder your AC has to work. Clean your filter regularly to ensure that your unit operates at maximum efficiency.

Conclusion

There are a lot of factors that affect the performance of your AC unit. Some of these can be prevented through proper maintenance, while others may mean severe damage that requires a professional technician.

It is best to get a professional who can offer air conditioning service. They can check for possible problems in your air conditioning unit, repair them, and prevent them from worsening. 

The cost of air conditioner maintenance is way cheaper than buying an entirely new unit. You are better off caring for your air conditioning unit and getting it maintained regularly.
