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

Air conditioners are often placed on concrete pads. Over time, the pad could crack, shift or sink. This can result in breakdowns and even premature replacement. Let’s review some of the problems 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 part. As its name suggests, it compresses liquid refrigerant that has turned into gas as it takes on 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.
  • A compressor that’s too hot.
  • More expensive utility bills due to less efficient cooling.

The compressor is one of the costliest parts to replace on your air conditioner. If it stops working, 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 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.
  • Damaged coils, which won’t be able to exhaust heat as efficiently.
  • Higher energy costs due to less efficient cooling.

3. More Wear and Tear

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

Excessive vibration could:

  • Put more strain on parts and wear them out faster.
  • Loosen refrigerant lines and cause a costly 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 experience. It’s typically not a job you’ll want to try on your own, because your air conditioner might need to be temporarily disconnected. This requires the help of a certified HVAC technician.
