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

Air conditioners are typically installed on concrete pads. Over time, the pad can crack, shift or sink. This can cause malfunctions and even premature replacement. Let’s discuss 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 a critical part. As its name suggests, 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 turns into liquid again.

The compressor needs oil to run properly. If your air conditioner isn’t level, its oil could be distributed unequally.

This can create:

  • Compressor damage because of grinding parts.
  • A compressor that’s too hot.
  • Higher energy 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. Rust and Mold

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 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 flowing away. This can cause:

  • Water accumulating near the air conditioner.
  • Rust and mold.
  • Damaged coils, which won’t be able to exhaust heat as efficiently.
  • Higher energy bills due to less efficient cooling.

3. More Wear and Tear

If your air conditioner isn’t level, it may vibrate excessively. This can cause annoying sounds when running and even require air conditioning repair.

Excessive vibration can:

  • Put more strain on parts and wear them out quicker.
  • 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 requires expertise. It’s usually not a job you’ll want to try by yourself, since your air conditioner might need to be temporarily disconnected. This requires the assistance of a certified HVAC technician.
