AC Replacement FAQs

On average, modern air conditioning systems last 10 to 15 years. Regular maintenance conducted by qualified professionals can maximize this potential.

Multiple factors can figure into the decision to replace an AC unit. If repair costs approach 50% of a replacement, that’s often an indicator that replacement is a good decision. The timing of a replacement, like around the time of the home’s sale, may also impact whether replacing is the best decision. Since cases like that are often unique, it depends on the situation.

It’s best to have a new AC unit installed before the summer hits to ensure you and your home are set up for success. This way, you won’t have to go without cool air when the temperatures are the highest.

A surefire way to select the best AC unit for your home is with the help of an expert. We will consider things like the size of your home and how much energy you wish to use to determine the best option.

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.
