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

August 23, 2021

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

Air conditioners are usually placed on concrete pads. As time passes, the pad can crack, shift or sink. This can cause breakdowns and even premature failure. Let’s review some of the malfunctions 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 implies, it compresses liquid refrigerant that has turned into gas as it absorbs heat from your house. Once the compressor exhausts heat under pressure, the refrigerant becomes 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.
  • 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 goes out, you’re better off doing air conditioning installation because of 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 through a line.

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

  • Water pooling around the air conditioner.
  • Rust and mold.
  • Damaged coils, which won’t be able to exhaust heat as well.
  • More expensive energy bills due to less efficient cooling.

3. More Wear and Tear

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

Excessive vibration could:

  • Put extra strain on parts and wear them out faster.
  • Loosen 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 takes experience. It’s typically not a job you’ll want to tackle by yourself, since your air conditioner might need to be temporarily disconnected. This requires the assistance of a certified HVAC technician.
