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

Air conditioners are often placed on concrete pads. Over time, the pad could crack, shift or sink. This can cause breakdowns and even premature replacement. Let’s go over some of the malfunctions that can happen and how to fix an air conditioner that isn’t level.

1. The Compressor Is Damaged

Your air conditioner’s compressor is a critical part. As its name suggests, it compresses liquid refrigerant that has turned into gas as it absorbs heat from your house. Once the compressor releases heat under pressure, the refrigerant turns into liquid again.

The compressor relies on oil to work properly. If your air conditioner isn’t level, its oil could be distributed unevenly.

This can create:

  • Compressor damage because of grinding parts.
  • An overheated compressor.
  • More expensive utility 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. 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 home. This moisture drains into a pan and then out via a line.

If your air conditioner isn’t level, water might end up pooling in the pan instead of draining away. This can lead to:

  • Water accumulating near the air conditioner.
  • Rust and mold.
  • Rusty coils, which won’t be able to get rid of heat as efficiently.
  • More expensive energy costs 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 cause obnoxious noises when on and even require air conditioning repair.

Too much vibration can:

  • Place extra strain on parts and wear them out faster.
  • Loosen refrigerant lines and cause a costly refrigerant leak.
  • Make your air conditioner sink further.
  • Eventually wear out your air conditioner much sooner.

How to Level an Air Conditioner Pad

Leveling an air conditioner pad requires expertise. It’s usually not a job you’ll want to try on your own, since your air conditioner might need to be temporarily disconnected. This requires the help of a certified HVAC technician.
