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

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

1. Damaged Compressor

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

This can cause:

  • Compressor damage due to 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 stops working, you’re better off doing air conditioning installation due to 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 drains into a pan and then out through 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 get rid of heat as efficiently.
  • Higher energy costs due to less efficient cooling.

3. Increased Wear and Tear

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

Excessive vibration can:

  • Put more strain on parts and wear them out quicker.
  • Loosen refrigerant lines and cause an expensive refrigerant leak.
  • Make your air conditioner sink further.
  • Eventually wear out your air conditioner much faster.

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, since your air conditioner may need to be temporarily disconnected. This requires the help of a certified HVAC tech.
