“I feel like the winter took me by surprise this year—especially when I woke up with no heat! I called Passion Heating and Air and tried to explain my problem. It couldn’t have been more than an hour or two before someone was at my home fixing it. Turned out not to be a big issue, and they got it up and running in no time. It’s good to know I have someone local I can trust if I have any heating or air problems. Thanks, guys!”

Charleston HVAC Services – FAQ

What size HVAC system do I need for my Charleston home?
HVAC sizing depends on your home’s square footage, insulation, and layout. Homes in Charleston often need slightly higher capacity units due to our humid subtropical climate. We provide free in-home assessments to ensure you get the perfect system. More info in our blog post here.
