Whether you’re getting 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 can crack, shift or sink. This can result in breakdowns and even premature replacement. Let’s go over some of the problems that can happen and how to fix an air conditioner that isn’t level.

1. Damage to the Compressor

Your air conditioner’s compressor is a critical 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 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 due to grinding parts.
  • An overheated compressor.
  • Higher utility bills due to less efficient cooling.

The compressor is one of the most expensive parts 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. 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 home. This moisture flows into a pan and then out through a line.

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

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

3. More Severe Wear and Tear

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

Too much vibration could:

  • Put extra strain on parts and wear them out faster.
  • Shake loose refrigerant lines and create 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 takes expertise. It’s usually not a job you’ll want to try by yourself, because your air conditioner might need to be temporarily disconnected. This requires the help of a certified HVAC tech.
