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

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

1. Your Air Conditioner’s Compressor Could Be Damaged

Your air conditioner’s compressor is a critical 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 turns into 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.
  • More expensive energy bills due to less efficient cooling.

The compressor is one of the most expensive parts to replace on your air conditioner. If it goes out, you’re better off doing air conditioning installation because of this part’s cost.

2. Mold and Rust May Accumulate

Water naturally occurs during the cooling process. Your air conditioner gets rid of moisture from the air as it cools your house. 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 cause:

  • 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 bills 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.

Excessive vibration could:

  • Place extra strain on parts and wear them out faster.
  • Shake loose refrigerant lines and cause a costly 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 takes experience. It’s usually not a job you’ll want to tackle by yourself, since your air conditioner might need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
