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

Air conditioners are usually installed on concrete pads. Over time, 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 fix an air conditioner that isn’t level.

1. Your Air Conditioner’s Compressor Could Be Damaged

Your air conditioner’s compressor is an important 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 work properly. If your air conditioner isn’t level, its oil could be distributed unevenly.

This can cause:

  • Compressor damage due to grinding parts.
  • A compressor that’s too hot.
  • Higher utility 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 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 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 pooling around the air conditioner.
  • Rust and mold.
  • Rusty coils, which won’t be able to get rid of heat as well.
  • Higher energy costs due to less efficient cooling.

3. Accelerated Wear and Tear

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

Excessive vibration could:

  • Put more strain on parts and wear them out quicker.
  • 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 takes expertise. 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 assistance of a certified HVAC technician.
