About HVAC service in Charleston
Homes in Charleston County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.

Charleston HVAC questions, answered
What brands do you service in Charleston?
All of them. Our 29401 technicians are trained on Carrier, Trane, Lennox, Rheem and essentially every other residential brand sold in South Carolina, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in South Carolina is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
What does a new system cost in Charleston?
A complete residential replacement in the 29401 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
