Even in best case scenarios, your air conditioner is only going to last 10 to 15 years. Do you know what this means?

At some point – it’s going to have to be replaced.

The question is – when?

The good news is, you don’t have to guess when to replace an air conditioner, as there are some tell-tale signs to watch for. Keep reading to learn what those signs are.

No Cold Air

This is the most obvious sign that your air conditioner may be past its prime, but it is worth mentioning. If there’s no cool air being produced, then there’s something wrong with the unit.

The issue could be a broken compressor, low freon level, or something else altogether. It’s a good idea to contact the professionals to determine if repair or replacement is appropriate.

It’s Inefficient

If the AC has a low SEER rating, it is going to cost you quite a bit to operate. The newer units are required to have a SEER rating of 13 at the minimum.

For home’s that still have a unit installed with a SEER rating under 13, they can reduce energy costs by replacing the system with a newer, more efficient unit.

In some cases, cleaning the interior and exterior unit can help with efficiency issues. You can read more about how to do this or contact the pros for more help.

However, if this doesn’t solve the issue, then a replacement may be necessary.

Leaks and Moisture Around Your Unit

While condensation around an air conditioner is completely normal, if there is excessive leakage, it can represent a much bigger issue. If there are large pools of water near the unit or a refrigerant leak, then there could be a more serious problem that needs to be addressed right away.

If the coolant is leaking, it can pose a serious health risk to you and your family. Excessive water leakage may cause damage to furniture and floors. It can even result in mold growth.

Unusual Sounds

Have you been hearing loud or grinding sounds coming from your air conditioner? Is there a squealing, banging, or rattling noise?

If so, turn the unit off and have a professional check out the problem right away. In most cases, these noises are going to indicate some type of serious problem, such as broken motor bearings or a belt that has slipped out of place.

Keep in mind, while DIY maintenance may help you prevent some problems, there are some issues that are unavoidable.

In many cases, the cost to fix this issue is not going to be worth it. At this point, investing in a replacement is the best course of action.
