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

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

1. Damaged Compressor

Your air conditioner’s compressor is a critical part. 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 needs oil to run properly. If your air conditioner isn’t level, its oil could be distributed unevenly.

This can cause:

  • Compressor damage because of grinding parts.
  • An overheated compressor.
  • More expensive electricity bills due to less efficient cooling.

The compressor is one of the most expensive parts 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 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 could end up pooling in the pan instead of draining away. This can lead to:

  • Water accumulating near 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 may vibrate excessively. This can create annoying sounds when on and even require air conditioning repair.

Too much vibration could:

  • Place extra strain on parts and wear them out faster.
  • Loosen refrigerant lines and cause a costly 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 usually not a job you’ll want to try on your own, since your air conditioner may need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
