What Charleston Homeowners Say

Don't take our word for it — here's what real customers have to say.

My AC stopped working on a Saturday in July — worst possible timing. I called Charleston AC & Heating Pros and they had a tech at my house within two hours. Fixed the problem same day, fair price, no runaround. These guys are the real deal.

I've used a few HVAC companies in the Charleston area and these guys stand out. The technician explained exactly what was wrong with my system, gave me an upfront price before touching anything, and had it fixed in under an hour. 5 stars, easy.

Called for an emergency at 11pm — yes, 11pm — and someone actually answered. Tech came out, diagnosed the issue, had parts on the truck and fixed it that night. I don't know any other company that does that. Highly recommend.

Frequently Asked Questions

How do I know if I need a new AC unit?

Signs it's time for a replacement include: your system is 10–15+ years old, repair costs exceed half the price of a new unit, energy bills are increasing significantly, or the system requires frequent repairs. We'll give you an honest assessment.

How long does AC installation take?

Most residential AC installations are completed in a single day — typically 4–8 hours depending on the system size and complexity of the installation.

What size AC unit do I need for my home?

AC sizing is based on square footage, ceiling height, insulation, window layout, and local climate. Charleston's heat and humidity require careful load calculations. Our technicians perform a full Manual J load calculation to ensure you get the right size — not too big, not too small.

What brands do you install?

We install all major HVAC brands including Carrier, Trane, Lennox, Rheem, Goodman, York, American Standard, and Bryant. We'll recommend the best option for your home and budget.

Do you offer financing for new AC systems?

Yes, financing options are available for qualified customers. Ask us about current financing promotions when you request a quote.

Will a new AC system save me money on energy bills?

Modern high-efficiency systems (16+ SEER) can reduce cooling costs by 20–40% compared to older systems. In Charleston's hot, humid climate, the savings add up quickly.
