What Lowcountry Locals Have to Say

Starr Quenelle
We had a great first experience with Dunes Heating and Air Conditioning, LLC, doing a routine service check on our HVAC system. Damien was thorough and, after catching a gas leak, came back to fix it the same day. We will definitely have them back out!
Paige Nageotte-Taylor
Leigh (I believe it is) was so friendly and accommodating when it came to my appointment and fitting me into their schedule. I cannot thank her enough. Damien is incredibly knowledgeable, and it shows how much he cares. He explained every single detail to me and broke it down in a way so I could fully understand. Dunes Heating and Air Conditioning, LLC will forever have my business because of their amazing team!
