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

Air conditioners are usually installed on concrete pads. As time passes, the pad could crack, shift or sink. This can result in breakdowns 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. Damaged Compressor

Your air conditioner’s compressor is an important 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 exhausts heat under pressure, the refrigerant turns into liquid again.

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

This can cause:

  • Compressor damage due to grinding parts.
  • An overheated compressor.
  • Higher electricity 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 because of 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 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 exhaust heat as well.
  • Higher energy costs due to less efficient cooling.

3. Increased Wear and Tear

If your air conditioner isn’t level, it may vibrate more than normal. This can create obnoxious sounds when running and even require air conditioning repair.

Excessive vibration could:

  • Put more strain on parts and wear them out quicker.
  • Loosen refrigerant lines and create an expensive 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 usually not a job you’ll want to tackle on your own, since your air conditioner may need to be temporarily disconnected. This requires the assistance of a certified HVAC tech.
