Should I repair or replace my air conditioner?

If you've had your AC for a while, you might wonder whether it's worth keeping, especially if it's been giving you a lot of trouble lately. Cooper technicians focus on helping homeowners maintain their current systems for as long as possible. However, there comes a time when maintaining an AC costs more than replacing it.

Consider replacing your air conditioner if:

Your system is over 10 years old
You're calling for repairs more often
Some rooms are too warm or never fully cool down
Energy bills have risen year after year
Your manufacturer's warranty has expired

"Cooper came highly recommended to me, and now I know why."

From start to finish, I was so pleased with this company's professionalism. Caleb was the Project Manager and the first person I interacted with. Very professional, and responded to all my questions and any phone calls I made promptly. Cooper came highly recommended to me, and now I know why. Never a need now for me to do that trying search for a company I can have confidence in - Cooper is it!!

AC repair cost factors:

Replacement parts

Depending on your AC issue, you may need one or two replacement parts. If so, the repair cost will increase based on the parts' price. The good news is that Cooper waives the diagnostic fee when your repair is done with us. That'll save you some money and make the repair more manageable financially.

Warranty status

Two types of warranties protect your AC. Part warranties cover specified system parts (subject to the manufacturer), while labor warranties cover the repair labor cost within a specific installation timeframe. If one or both of these warranties are active on your system, you'll pay less or nothing for the repair.

Contractor experience

Contractor experience is essential because it dictates how much your contractor charges for labor. Cooper, for instance, has labor costs that are a bit higher than average. But we make up for it with the skill of our technicians, the customer service we provide, and the post-service support you'll get if anything goes wrong with the repair.

Looking for a precise quote?

We can help. When you call Cooper, we'll send over a technician as soon as possible to diagnose your system. From there, we'll provide an upfront, down-to-the-penny quote to repair your AC.

AC Repair FAQs

Weak airflow, warm air, unusual noises, frequent cycling, and rising energy bills are all signs your system may need professional repair.

This could be caused by refrigerant issues, a dirty evaporator coil, or a malfunctioning compressor.

Address AC problems as soon as possible to prevent further damage and avoid complete system failure during high-demand periods.

It’s best to turn it off and schedule service. Grinding, banging, or squealing sounds often indicate mechanical issues that can worsen if ignored.

Costs vary depending on the issue, but early repairs are usually more affordable than waiting until major components fail.
