Fast, honest air conditioning repair for the Lowcountry — every make and model.
Cooling
A dead air conditioner in a Charleston July is not something you wait out. The humidity moves in fast, and the house is unlivable by afternoon. Alexander Heating & Cooling repairs air conditioners across the Charleston area seven days a week — and our reviews keep saying the same two things: we respond quickly, and we explain what is wrong before we fix it.
Open 7 days a week, 8 AM to 8 PM on weekdays. When your AC quits, you are not waiting until Monday.
We diagnose and repair all major brands — and as a Heil dealer, we can quote a replacement if your system is truly done.
Our techs walk you through what failed and why. One reviewer put it simply: Matt "took the time to explain everything clearly."
Open 7 Days
Call (843) 608-1689 any day of the week — or send the form and we will get right back to you. Honest pricing, clear answers, and a crew your neighbors already rated 5.0 stars.
How It Works
Give us a call at (843) 608-1689 or fill out the form. We will ask a few questions about what is going on.
Our technician finds the real problem and gives you clear pricing before any work starts.
We finish the job, clean up after ourselves, and test everything before we leave. Done means done.
Charleston air conditioners work harder than almost anywhere. The cooling season stretches from April into October, the humidity forces long run times, and salt air off the harbor corrodes outdoor coils years ahead of schedule. A system that limped through last summer often quits completely in the next heat wave — which is why odd noises, weak airflow, or ice on the refrigerant lines deserve a call before they become a breakdown.
If your system is at the end of its life, a repair can be money spent on a unit that is about to fail again. If it has years left, replacement is overkill. We give you the honest math for both paths and let you decide — and when replacement wins, our installations come backed by warranties and a crew that protects your home while they work.
