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

Air conditioners are typically placed on concrete pads. Over time, the pad could crack, shift or sink. This can cause breakdowns and even premature replacement. Let’s discuss some of the malfunctions 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 an important component. As its name implies, it compresses liquid refrigerant that has turned into gas as it absorbs 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 create:

  • Compressor damage due to 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 breaks, 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 gets rid of 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 bills due to less efficient cooling.

3. Increased Wear and Tear

If your air conditioner isn’t level, it may vibrate excessively. This can create annoying sounds when on and even require air conditioning repair.

Excessive vibration can:

  • Place extra strain on parts and wear them out faster.
  • Loosen refrigerant lines and create an expensive 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, since your air conditioner might need to be temporarily disconnected. This requires the help of a certified HVAC tech.
