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, 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 cause breakdowns and even premature replacement. Let’s discuss some of the issues 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 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 releases heat under pressure, the refrigerant becomes 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 cause:

  • Compressor damage due to grinding parts.
  • An overheated compressor.
  • More expensive energy bills due to less efficient cooling.

The compressor is one of the costliest parts to replace on your air conditioner. If it stops working, 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 drains 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 draining 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 efficiently.
  • Higher energy bills due to less efficient cooling.

3. Increased Wear and Tear

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

Too much vibration could:

  • Place extra strain on parts and wear them out faster.
  • Shake loose refrigerant lines and cause an expensive 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, because your air conditioner might need to be temporarily disconnected. This requires the assistance of a certified HVAC technician.
