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

Air conditioners are often 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 problems that can happen and how to fix an air conditioner that isn’t level.

1. Your Air Conditioner’s Compressor Could Be Damaged

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 house. Once the compressor exhausts 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 because of grinding parts.
  • A compressor that’s too hot.
  • Higher electricity bills due to less efficient cooling.

The compressor is one of the most expensive parts 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. Mold and Rust May Accumulate

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 might end up pooling in the pan instead of flowing away. This can cause:

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

3. More Wear and Tear

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

Excessive vibration could:

  • Place more strain on parts and wear them out quicker.
  • Shake loose refrigerant lines and cause 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 requires expertise. It’s usually not a job you’ll want to tackle on your own, since your air conditioner might need to be temporarily disconnected. This requires the help of a certified HVAC technician.
