You’re sitting in your home enjoying a bit of television after a long day at work when your ac starts to make the most peculiar sound. It sounds like it’s struggling to work which may be the case because your unit is about ten years old.

In this scenario, the age coupled with the fact that the unit is quite old is a pretty large indicator that you need to have your unit replaced. If it was a bit younger you may have been able to repair it.

There is a very fine line between being able to simply repair your ac unit and having to get a new one altogether. To help you make the distinction, here are a few tips that may help you decide which one you should do.

1. Benefits of Replacing

Before we get into how to tell if you should replace or repair your unit, we’re going to briefly go over the benefits of each. Here are a few good reasons why you should replace your ac unit even if you could possibly stretch out the life of your old one. 


Chances are you’ve already blown through your warranty with your old unit. Getting a new one could be an easy way of sort of resetting your warranty because a new unit, means a new warranty. 

Going Green

In an effort to take a little stress off the ozone layer, newer AC models are created with a more eco-friendly refrigerant than the older ones. So, if you replace your old model you’ll be able to cool your home and save the environment too. It’s a win-win for everyone. 

More Convenience

When your old AC unit breaks down you may have to wait for weeks for parts to come in because well, it’s old. The older any machine gets the harder it is for manufacturers to find parts for it. 

You can cut down on this wait time by upgrading. If you have a newer model, you may have to wait a few days for a part to come in but it won’t be that long. 

2. Benefits of Repairing

While replacing probably sounds great to you right now, there are a few benefits to repairing your unit. The major reasons why you would want to repair instead of replacing is if you need to save a little bit of money or if you want to hold back from buying a new unit because you plan on moving one day. 

Saving Money

Unless you’re having to dish out several hundred dollars a month on repairs for your unit, you may be able to hold off on replacing it. The reason why you would want to hold off is that the upfront cost for a new unit will be expensive. 

If you don’t have that kind of money sitting around in your wallet, go with the repair for now and save cash. 

Are You Moving? 

If you’re planning on selling your home soon, you’re not going to want to pump hundreds of dollars into a new AC unit only to leave. While it may be hard to sell your current home with it having an old AC unit, you’ll probably still be able to find a buyer without having to make the replacement. 

3. When Should You Replace Your Unit

Even though you may be able to push back replacing your unit for a little while, there comes a time when you can’t save it anymore. The four key ways to tell you should go with a replacement are your current unit’s age, how often your current one breaks down, if the temperature in your home is uneven, and if there is a lot of noise coming from the unit. 


It is recommended that you replace your AC unit once every ten years. While you can stretch it over the ten-year mark, the older it gets the less energy efficient it is. You’ll be able to shave a lot more off your energy bills if you replace it after it celebrates its big ten. 

Yours Breaks Down Frequently

If you’re not having to spend too much money replacing your unit every few months then you can repair it. If you feel like it’s being repaired more often then it’s cooling your home though, you need to go ahead and replace it. 

At that point, it’s costing you too much money to be efficient on your wallet anymore. So, even though a new one will be a lot of money, it would be worth it. 

Uneven temperatures

Do you often find that some rooms in your home are warmer than others? This is  because your unit is no longer cooling your home evenly. If this is the case then you may want to replace your unit before your whole home turns into a sauna. 


If your current unit is making a ton of noise this means that it’s struggling to do its job. After a while, this struggle will show in your energy bill because it’s using a lot of power to cool your home. At this point, you could try and repair it but you’re better off putting it out of its misery.
