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

Air conditioners are usually placed on concrete pads. Over time, the pad can crack, shift or sink. This can result in breakdowns and even premature replacement. Let’s go over some of the malfunctions that can happen and how to fix an air conditioner that isn’t level.

1. Damage to the 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 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 because of grinding parts.
  • An overheated compressor.
  • 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 stops working, you’re better off doing air conditioning installation because of this part’s cost.

2. The AC Unit Will Rust and Collect 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 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 Severe 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 more strain on parts and wear them out faster.
  • Shake loose refrigerant lines and create an expensive refrigerant leak.
  • Make your air conditioner sink further.
  • Eventually wear out your air conditioner much faster.

How to Level an Air Conditioner Pad

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