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

Air conditioners are typically installed on concrete pads. As time passes, the pad can crack, shift or sink. This can result in malfunctions and even premature failure. Let’s discuss some of the problems that can happen and how to fix an air conditioner that isn’t level.

1. Damaged Compressor

Your air conditioner’s compressor is an important part. As its name suggests, it compresses liquid refrigerant that has turned into gas as it takes on heat from your house. Once the compressor releases heat under pressure, the refrigerant becomes 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 due to grinding parts.
  • A compressor that’s too hot.
  • Higher utility bills due to less efficient cooling.

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

2. Mold and Rust May Accumulate

Water is a natural byproduct of the cooling process. Your air conditioner gets rid of moisture from the air as it cools your home. 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 flowing away. This can cause:

  • 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. Accelerated Wear and Tear

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

Too much vibration could:

  • Place extra strain on parts and wear them out faster.
  • Shake loose refrigerant lines and create a costly refrigerant leak.
  • Make your air conditioner sink even more.
  • Eventually wear out your air conditioner much faster.

How to Level an Air Conditioner Pad

Leveling an air conditioner pad takes experience. 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 tech.
