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

Air conditioners are usually placed on concrete pads. Over time, the pad could 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 repair 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 takes on heat from your house. Once the compressor releases heat under pressure, the refrigerant turns into liquid again.

The compressor relies on 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.
  • 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 drains into a pan and then out via a line.

If your air conditioner isn’t level, water could end up pooling in the pan instead of flowing 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.
  • Higher 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 annoying sounds when on and even require air conditioning repair.

Too much vibration can:

  • Put more 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 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 tackle by yourself, since your air conditioner may need to be temporarily disconnected. This requires the help of a certified HVAC technician.
