HVAC systems can last a really long time with the right maintenance and regular repairs, which means a decision to repair or replace your air conditioning unit should be a choice you only make a few times in your life. But while you may be able to get by with regular repairs for a while, eventually you'll need to consider whether or not you need a full replacement. The choice can be hard, so we came up with a few questions you can ask yourself to determine if it's time to replace your unit or simply schedule an air conditioning repair service.

How Old Is Your Unit?

As mentioned above, air conditioning systems can last a while — anywhere from 12 to 17 years if taken care of properly. That being said, if your unit starts approaching the halfway point of that mark, you might notice that the frequency and intensity of repairs start to pick up substantially. Parts will start to come loose and your ventilation will start to pull apart, which will necessitate more frequent repairs. Instead of simply having an air conditioner repair service performed constantly, you may be better off to have a brand-new system installed to give yourself peace of mind.

How Much Are the Repairs?

Compared to some of the things you can do in your home, air conditioning repairs are relatively inexpensive. Still, it's a good idea to add up the cost of your repairs and see if it makes more financial sense to simply spring for a replacement. Here's a good rule of thumb: if your air conditioning repairs cost more than 50% of what a new unit would cost, it makes more financial sense to replace it. Not only will you have a more efficient unit, but you also have a warranty that should cover the cost of any repairs in the near future.

Do You Want to Upgrade?

Like everything else that's in your home, air conditioning technology has come a long way over the last few decades. Newer units are much more energy-efficient than they used to be, which keeps your utility bills down and more money in your pocket where it belongs. Moreover, in the world of smart homes, you can even have a system that is able to be adjusted straight from your smartphone, or sometimes, even by voice-activated commands. Regardless of whether you want to upgrade or not, it's a good idea to check what type of units are available on the market the next time you have to schedule an air conditioner repair service.
