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.

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

Why is my heat pump blowing cold air in heat mode?

This is often caused by a reversing valve failure, low refrigerant, a dirty air filter, or the system being in defrost mode. If defrost mode is not the cause, a technician should diagnose it quickly — especially on cold nights.

How often should I have my furnace serviced?

Annual maintenance before the heating season is recommended. A tune-up improves efficiency, extends equipment life, and helps catch small issues before they become costly breakdowns.

What's the difference between a heat pump and a furnace?

A heat pump moves heat from the outside air (or ground) into your home using refrigerant. A furnace generates heat by burning natural gas, propane, or using electric resistance. Charleston's mild winters make heat pumps particularly efficient here.

My heating system is making a banging noise — should I be concerned?

Banging, clanking, or rattling from your heating system can indicate loose components, dirty burners, duct expansion, or a cracked heat exchanger. A cracked heat exchanger is a safety issue — call us immediately.

Can you repair all heating system brands?

Yes. We repair all major heat pump and furnace brands including Carrier, Trane, Lennox, Rheem, Goodman, York, American Standard, and more.
