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

Air conditioners are typically installed on concrete pads. Over time, the pad could crack, shift or sink. This can cause breakdowns and even premature failure. Let’s review some of the problems that can happen and how to repair an air conditioner that isn’t level.

1. The Compressor Is Damaged

Your air conditioner’s compressor is an important component. 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 run 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 utility bills due to less efficient cooling.

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

2. The AC Unit Will Rust and Collect Mold

Water naturally occurs during the cooling process. Your air conditioner gets rid of moisture from the air as it cools your house. This moisture flows into a pan and then out via a line.

If your air conditioner isn’t level, water could end up accumulating 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. Accelerated Wear and Tear

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

Too much vibration can:

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

Steps for Leveling Your Air Conditioner Pad

Leveling an air conditioner pad takes experience. It’s usually not a job you’ll want to try on your own, since your air conditioner may need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
