Why is My AC Running but Not Cooling?

Why is My AC Running but Not Cooling?

There are several reasons why your air conditioner might be running but not cooling efficiently. Some of the most common reasons include:


Dirty or Clogged Air Filter

A clogged or dirty air filter can restrict airflow and cause your AC to work harder to cool your home. This can result in overheating, which can lead to system breakdowns and costly repairs. Fortunately, this issue can usually be solved by replacing the filter, without a call to us for repairs.

Low Refrigerant

Refrigerant is the chemical used to cool the air inside your AC. If the refrigerant levels are low, your AC won’t be able to cool your home effectively. Low refrigerant levels could be due to a leak in the system, which will need to be repaired. In many cases, it may make the most sense to repair a refrigerant leak. However, if you have an older system that still uses Freon refrigerant, you may want to consider replacing the unit.

Faulty Compressor

The compressor is the heart of your central air conditioning system. It compresses the refrigerant and circulates it through the system to cool your home. If the compressor is faulty or damaged, it won’t be able to do its job effectively, resulting in poor cooling performance.

The compressor can be replaced in most cases without having to replace the entire unit, but depending on the cost and other factors, you may wish to go ahead and upgrade to a new cooling system.

Dirty Coils

Over time, the coils in air conditioning systems can become dirty or clogged with debris, reducing their ability to transfer heat. This can cause your AC to work harder while producing less cooling, leading to higher energy bills and a less comfortable home.

Coils can be kept clean by scheduling an annual maintenance appointment with our team.

When Should You Repair or Replace Your AC?

If your AC is running but not cooling, it’s essential to determine whether the problem is a minor one that can be repaired or a more significant issue that requires a replacement. Here are some factors to consider:

Age of Your AC

If your air conditioner is over ten years old, it might be more cost-effective to replace it rather than repair it. An old, inefficient AC can be a money pit, with frequent breakdowns and high energy bills.

Cost of Repairs

If the cost of repairing your AC is more than 50% of the cost of a new AC system, it’s probably time to replace it. Frequent repairs can also indicate that your AC is outdated and struggling to keep up with your needs.

Energy Efficiency

If your central air conditioner, heat pump, or ductless AC equipment is outdated, it’s likely not very energy efficient. A new, high-efficiency AC unit can save you hundreds of dollars on your energy bills while improving your comfort levels.
