When an air conditioner takes a long time to cool a house, that is an indication that something is not working properly. This article offers a few reasons that your AC might not be working as effectively as it could be.

If your central air conditioner does not cool your home properly, you may be able to fix the problem in a few simple steps. On the other hand, the cause may require professional help.

Air conditioner takes a long time to cool house? Here are some possible causes of an inefficient cooling system:

  1. Dirty air filter
  2. Dirty condenser coils
  3. Leaky ductwork
  4. Refrigerant leak
  5. Air conditioner too small for space

For tips on how to fix these problems, read on and find out why your air conditioner takes a long time to cool your house.

Dirty Air Filter

Your AC’s filter takes all of the nasty stuff out of your home’s air. In time, all the dust, pollen, hair, and dirt can block the flow of cool air from circulating properly. Not only can a dirty air filter keep your home warmer than you would like, but it can also raise your energy consumption because of the extra power it takes to get your home to the desired temperature.

If your AC is having trouble keeping your home cool, check the air filter. It may need to be cleaned or replaced.

Dirty Condenser Coils

When an air conditioner takes a long time to cool a house, the problem could be dirty condenser coils. The portion of your central AC unit that sits outside often becomes dirty from all the outdoor pollutants, pollen, and dust in the air. When this happens, the condenser coils may have trouble getting rid of heat, which can force your system to work overtime.

Leaky Ductwork

Another common reason for inadequate cooling in your home could be leaky ductwork. The air ducts that transport cool air throughout your home may have gaps where they are joined together, which can force cool air into spaces you don’t necessarily need to keep cool. A professional AC technician will be able to locate and seal your leaky ducts.

Refrigerant Leak

If your central air is making bubbling or hissing noises, your problem might be a refrigerant leak. When your AC is leaking refrigerant, it won’t have enough to cool your house properly. You will need to have a professional seal the leak, and in some instances, they may need to replace the entire coil.

Air Conditioner System Too Small

Air conditioning systems come in different sizes for different homes. Your AC may not be cooling your home effectively if it is too small for the space. If this is the case, you may need to install a new system if you want to keep your rooms at a comfortable temperature.
