3 Things That Can Go Wrong If Your Air Conditioner Isn't Level

August 23, 2021

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

Air conditioners are typically placed on concrete pads. As time passes, the pad could crack, shift or sink. This can cause 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. 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 absorbs heat from your home. Once the compressor releases heat under pressure, the refrigerant turns into liquid again.

The compressor relies on 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.
  • More expensive utility 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 due to this part’s cost.

2. Rust and Mold

Water is a natural byproduct of the cooling process. Your air conditioner removes moisture from the air as it cools your house. This moisture flows into a pan and then out via a line.

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

  • Water accumulating near the air conditioner.
  • Rust and mold.
  • Rusty coils, which won’t be able to get rid of heat as efficiently.
  • More expensive 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 annoying noises when running and even require air conditioning repair.

Excessive vibration can:

  • Put extra strain on parts and wear them out faster.
  • Shake loose refrigerant lines and cause an expensive refrigerant leak.
  • Make your air conditioner sink even more.
  • Eventually wear out your air conditioner much sooner.

How to Level an Air Conditioner Pad

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