3 Things That Can Go Wrong If Your Air Conditioner Isn't Level

August 23, 2021

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

Air conditioners are often installed on concrete pads. As time passes, the pad could crack, shift or sink. This can result in 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. 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 unevenly.

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 breaks, 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 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 flowing away. This can lead to:

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

3. More Wear and Tear

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

Excessive vibration could:

  • Place more strain on parts and wear them out faster.
  • Loosen refrigerant lines and create a costly 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 takes experience. It’s typically not a job you’ll want to try by yourself, since your air conditioner might need to be temporarily disconnected. This requires the help of a certified HVAC tech.
