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

Air conditioners are typically placed on concrete pads. Over time, the pad can crack, shift or sink. This can result in breakdowns and even premature failure. Let’s go over some of the issues 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 component. As its name suggests, it compresses liquid refrigerant that has turned into gas as it takes on heat from your home. Once the compressor releases 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 because of 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 breaks, 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 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 more than normal. This can create obnoxious sounds when on and even require air conditioning repair.

Excessive 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 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 might need to be temporarily disconnected. This requires the help of a certified HVAC tech.
