What Customers Say in Charleston

“Furnace was short cycling every five minutes. Turned out to be a flame sensor and a dirty filter. Honest fix, honest price.”

Carla D., Charleston

“Duct sealing made a bigger difference than I expected. Upstairs finally cools down and the system is not running all day.”

Terrence L., Charleston

“The tune-up caught a weak capacitor before summer. Five minutes to fix then, would have been a no-cool call in August.”

Monica S., Charleston

AC Service & Tune-Up in Charleston: Questions We Hear

How often should I service my AC in Charleston?

Once a year for straight cooling systems and twice a year for heat pumps, ideally in spring before the first heat wave.

Does a tune-up really lower my bill?

A dirty coil and low charge can cut efficiency by 20 to 30 percent. Cleaning and correcting the charge usually shows up on the next power bill.

Do you offer a maintenance plan?

Yes. Our annual plan includes both seasonal visits, priority scheduling and a discount on repairs.

Do you offer AC maintenance near Downtown Charleston?
