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

Air conditioners are often installed on concrete pads. Over time, the pad could crack, shift or sink. This can result in malfunctions and even premature replacement. Let’s review some of the malfunctions that can happen and how to repair an air conditioner that isn’t level.

1. Your Air Conditioner’s Compressor Could Be Damaged

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

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

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 fails, 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 gets rid of 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 could 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 get rid of heat as well.
  • More expensive energy bills due to less efficient cooling.

3. More Severe Wear and Tear

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

Excessive vibration could:

  • Put more strain on parts and wear them out faster.
  • Loosen refrigerant lines and cause a costly refrigerant leak.
  • Make your air conditioner sink even more.
  • Eventually wear out your air conditioner much sooner.

How You Can Level Out Your Air Conditioner Pad

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