Local Know-How

HVAC Needs in Charleston Homes

Charleston has some of the oldest housing stock in the region. Many older homes were never designed for central air, so ductwork can be tight, leaky or hard to reach. Ductless mini-split systems are often a smart fit when there is no room for new ducts.

The city also deals with heavy humidity for much of the year. An air conditioner that is the wrong size can cool a room without pulling enough moisture out of the air. We size and set up systems so they handle both temperature and humidity.

Questions & Answers

Frequently Asked Questions

Do you serve all of Charleston?

Yes. We serve homes and businesses throughout Charleston, including the peninsula and surrounding neighborhoods. Call (843) 969-2269 to confirm service at your address.

How quickly can you get to my Charleston home?

Most appointments are scheduled within 24 to 48 hours, and we offer same-day service for emergencies whenever possible. Our hours are Monday to Friday 8am to 6pm and Saturday 9am to 3pm.

Can you add central air or a mini-split to an older Charleston home?

Often, yes. We look at the layout, existing ductwork and available space, then recommend the option that makes sense. In many older homes a ductless mini-split is the least invasive choice.
