A family name on the van, 30+ years of hands-on experience behind it.
Our Story
Chris Alexander spent more than 30 years working on heating and cooling systems before putting his own name on the door. In 2019 he founded Alexander Heating and Cooling LLC in Charleston — a family-owned company built on a simple idea: do the work the way you would want it done in your own house, and the reviews take care of themselves.
They have. Alexander holds a 5.0-star Google rating across 440+ reviews, and the same words keep appearing in them: responsive, professional, fair, honest. Customers mention Chris and his technicians by name, because when you call Alexander, those are the people who actually show up — seven days a week, from our shop at 461 Jessen Ln.
We are a Heil dealer for full systems, we install Mitsubishi ductless mini splits and Rinnai tankless water heaters, and we service every major brand across Charleston, Mount Pleasant, Daniel Island, the beach islands, and out to Huger.
What We Stand On
Sized right, installed clean, tested before we leave. Reviewers call it craftsmanship — we call it the job.
Floors protected, questions answered, everything cleaned up. Your house should look better after we visit, not worse.
Honest quotes, real recommendations, and both numbers when repair and replacement are on the table.
