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

Air conditioners are usually placed on concrete pads. Over time, the pad could crack, shift or sink. This can cause malfunctions and even premature replacement. Let’s review some of the problems 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 home. Once the compressor releases 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 unequally.

This can cause:

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

2. Rust and Mold

Water is a natural byproduct of 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 could end up accumulating in the pan instead of draining away. This can lead to:

  • Water accumulating near the air conditioner.
  • Rust and mold.
  • Damaged coils, which won’t be able to get rid of heat as efficiently.
  • More expensive energy costs due to less efficient cooling.

3. Increased 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.

Excessive vibration can:

  • Place more 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 expertise. It’s typically not a job you’ll want to tackle by yourself, because your air conditioner might need to be temporarily disconnected. This requires the help of a certified HVAC technician.
