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

Air conditioners are often placed on concrete pads. As time passes, the pad could crack, shift or sink. This can result in malfunctions and even premature replacement. Let’s go over 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 part. As its name implies, it compresses liquid refrigerant that has turned into gas as it takes on heat from your house. Once the compressor releases heat under pressure, the refrigerant becomes liquid again.

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

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 costliest components to replace on your air conditioner. If it fails, you’re better off doing air conditioning installation due to this part’s cost.

2. The AC Unit Will Rust and Collect Mold

Water naturally occurs during the cooling process. Your air conditioner removes moisture from the air as it cools your home. This moisture drains into a pan and then out through a line.

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

  • 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 may vibrate more than normal. This can cause obnoxious noises when running and even require air conditioning repair.

Excessive vibration can:

  • Place more strain on parts and wear them out faster.
  • Loosen refrigerant lines and cause an expensive 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 expertise. It’s typically not a job you’ll want to try on your own, since your air conditioner might need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
