What we do

Working North Charleston

We have worked in Park Circle, Wescott Plantation, and Cane Bay.

Drive time from our shop: 14 min

The Lowcountry runs humid nine months of the year, and humidity is what actually breaks systems here: coils stay wet, drain lines clog, and a unit that is one ton oversized short-cycles instead of pulling moisture out of the house. We size for latent load, not just square footage.

What customers saySample content

Marcus
★★★★★
Our upstairs unit quit on the first really humid week of the summer. They had a tech out the same afternoon, found a failed capacitor, and had cold air back before dinner. Clean work, shoe covers, no upsell.
Sample review for demonstration, 3 weeks ago
Danielle
★★★★★
We signed up for the maintenance plan after they tuned the system in the spring. The humidity in the house is noticeably better and the power bill came down two months running. Straight answers every time I call.
Sample review for demonstration, 2 months ago
Trey
★★★★★
Full replacement on a 19 year old system. They walked me through sizing instead of just quoting the biggest box, showed up when they said, and cleaned up the crawlspace better than they found it.
