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

Air conditioners are usually placed on concrete pads. Over time, the pad can 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 repair an air conditioner that isn’t level.

1. Damage to the 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 takes on heat from your home. Once the compressor exhausts heat under pressure, the refrigerant turns into liquid again.

The compressor needs 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.
  • More expensive electricity bills due to less efficient cooling.

The compressor is one of the costliest components to replace on your air conditioner. If it goes out, you’re better off doing air conditioning installation due to 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 home. This moisture flows into a pan and then out through a line.

If your air conditioner isn’t level, water could end up accumulating in the pan instead of flowing away. This can cause:

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

3. More Wear and Tear

If your air conditioner isn’t level, it might vibrate excessively. This can create annoying noises when on and even require air conditioning repair.

Excessive vibration could:

  • Put extra strain on parts and wear them out quicker.
  • Shake loose refrigerant lines and create a costly 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 takes expertise. It’s typically 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.
