Whether you’re installing a new air conditioner or looking 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 cause malfunctions and even premature replacement. Let’s review some of the malfunctions that can happen and how to repair an air conditioner that isn’t level.

1. The Compressor Is Damaged

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 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 create:

  • Compressor damage because of grinding parts.
  • A compressor that’s too hot.
  • Higher electricity bills due to less efficient cooling.

The compressor is one of the costliest parts to replace on your air conditioner. If it goes out, 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 removes moisture from the air as it cools your house. This moisture drains 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 exhaust heat as well.
  • More expensive energy bills due to less efficient cooling.

3. Increased Wear and Tear

If your air conditioner isn’t level, it might vibrate more than normal. This can create obnoxious sounds when running and even require air conditioning repair.

Excessive vibration could:

  • Place extra strain on parts and wear them out quicker.
  • Shake loose refrigerant lines and create a costly refrigerant leak.
  • Make your air conditioner sink further.
  • Eventually wear out your air conditioner much faster.

Steps for Leveling Your Air Conditioner Pad

Leveling an air conditioner pad requires experience. It’s typically not a job you’ll want to try on your own, because your air conditioner may need to be temporarily disconnected. This requires the help of a certified HVAC tech.
