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

Air conditioners are typically placed on concrete pads. Over time, the pad can crack, shift or sink. This can result in malfunctions and even premature replacement. Let’s review some of the malfunctions 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 part. As its name implies, it compresses liquid refrigerant that has turned into gas as it absorbs heat from your home. Once the compressor exhausts 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 unevenly.

This can create:

  • Compressor damage because of grinding parts.
  • A compressor that’s too hot.
  • Higher energy bills due to less efficient cooling.

The compressor is one of the costliest components to replace on your air conditioner. If it breaks, you’re better off doing air conditioning installation because of 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 pooling in the pan instead of flowing 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.
  • Higher energy bills due to less efficient cooling.

3. More Wear and Tear

If your air conditioner isn’t level, it might vibrate excessively. This can create obnoxious sounds 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 create a costly refrigerant leak.
  • Make your air conditioner sink even more.
  • Eventually wear out your air conditioner much sooner.

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 on your own, because your air conditioner might need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
