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

Air conditioners are usually placed on concrete pads. Over time, the pad can crack, shift or sink. This can result in malfunctions and even premature failure. Let’s go over some of the problems that can happen and how to repair an air conditioner that isn’t level.

1. The Compressor Is Damaged

Your air conditioner’s compressor is a critical component. As its name suggests, it compresses liquid refrigerant that has turned into gas as it takes on heat from your home. Once the compressor exhausts heat under pressure, the refrigerant becomes liquid again.

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

This can cause:

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

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

2. The AC Unit Will Rust and Collect Mold

Water naturally occurs during the cooling process. Your air conditioner removes moisture from the air as it cools your house. This moisture drains 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 flowing away. This can lead to:

  • Water accumulating near the air conditioner.
  • Rust and mold.
  • Damaged coils, which won’t be able to get rid of heat as well.
  • More expensive energy costs due to less efficient cooling.

3. More Wear and Tear

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

Excessive vibration could:

  • Place extra strain on parts and wear them out faster.
  • Loosen refrigerant lines and create an expensive refrigerant leak.
  • Make your air conditioner sink even more.
  • Eventually wear out your air conditioner much sooner.

How to Level an Air Conditioner Pad

Leveling an air conditioner pad requires experience. It’s typically not a job you’ll want to try by yourself, since your air conditioner may need to be temporarily disconnected. This requires the help of a certified HVAC tech.
