3 Things That Can Happen If Your Air Conditioner Isn't Level

August 23, 2021

Whether you’re installing a new air conditioner or looking to maximize your current one, having it level is key.

Air conditioners are often placed on concrete pads. As time passes, the pad could crack, shift or sink. This can cause malfunctions and even premature failure. Let’s review some of the issues that can happen and how to fix an air conditioner that isn’t level.

1. Damaged Compressor

Your air conditioner’s compressor is an important part. As its name suggests, it compresses liquid refrigerant that has turned into gas as it takes on heat from your house. Once the compressor releases heat under pressure, the refrigerant becomes liquid again.

The compressor needs oil to work properly. If your air conditioner isn’t level, its oil could be distributed unevenly.

This can create:

  • Compressor damage because of grinding parts.
  • A compressor that’s too hot.
  • Higher electricity bills due to less efficient cooling.

The compressor is one of the most expensive components to replace on your air conditioner. If it fails, you’re better off doing air conditioning installation because of this part’s cost.

2. Rust and Mold

Water naturally occurs during the cooling process. Your air conditioner gets rid of moisture from the air as it cools your house. This moisture flows into a pan and then out via a line.

If your air conditioner isn’t level, water might end up accumulating in the pan instead of draining away. This can lead to:

  • Water pooling around the air conditioner.
  • Rust and mold.
  • Damaged coils, which won’t be able to exhaust heat as well.
  • More expensive energy bills due to less efficient cooling.

3. Increased Wear and Tear

If your air conditioner isn’t level, it may vibrate more than normal. This can create obnoxious noises when running and even require air conditioning repair.

Too much vibration can:

  • Place extra strain on parts and wear them out quicker.
  • Shake loose refrigerant lines and create an expensive refrigerant leak.
  • Make your air conditioner sink further.
  • Eventually wear out your air conditioner much sooner.

How to Level an Air Conditioner Pad

Leveling an air conditioner pad requires experience. It’s usually not a job you’ll want to try on your own, because your air conditioner might need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
