I have used D&S for 20 years. Great service and prices. Just replaced my HVAC system they installed 19 years ago. Must be a record at the beach.

I had a great experience with D&S Heating & Cooling. They added three small return air ducts to all three upstairs bedrooms and resized the ductwork to the main upstairs return to properly balance airflow.

We had a tricky problem at our house and Patrick and his team patiently, politely and professionally worked the problem. They do a great job with our scheduled service!

Our story

62 years in Beaufort.

Jay and Patrick Dennis run what their family started in 1964: honest HVAC work, done right the first time.

We've serviced the Beaufort area for over 60 years, and our technicians stay current with new methods and principles in heating and cooling systems. Customer satisfaction isn't a tagline for us—it's how we've stayed in business this long.

How it works

From first call to job done.

  1. Tell us about it

    Quick form or a phone call — whichever's easier. We don't make you fill out anything you don't have to.

  2. We come look

    A no-cost site visit so we see what's there and talk through what you want.

  3. Clean estimate

    Itemized, in writing, with a start date. No surprises mid-project, no upcharges later.

  4. We get to work

    Same crew lead from day one to handoff — and a direct line if anything needs adjusting.
