How To Know When It’s Time To Replace Your AC Unit

Although issues with your AC unit are usually obvious, you may not always realize that they can indicate the end of its service life. In order to determine the need for a total system replacement, look out for the following signs:

  • Your unit is 10 to 15 years old
  • Your unit won’t turn on
  • Your unit doesn’t produce cool air
  • Your power bill is consistently high
Should any of the above be true for your unit, it’s time to consider an AC replacement. Request a free estimate by calling (833) 232-4328.

How Long Are AC Units Expected To Last?

As mentioned above, AC units typically last 10 to 15 years, although the life span of your unit can vary due to a number of things. If your unit is always being used, it will be met with more wear and tear that will ultimately play a role in how long it will operate efficiently. If you are on top of repairs and annual maintenance, it could be that your specific unit lasts even longer than the average time frame!

Benefits Of Replacing Your AC System

Your old, overused AC unit likely isn’t cutting it anymore. When you’re ready to work with A+ Derr to achieve a top-notch AC replacement, you can expect the following benefits:

  • Increased performance
  • Heightened comfort

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
