About Alexander

About Alexander Heating & Cooling

Chris Alexander has spent more than 30 years working on heating and cooling systems with his own hands — and in 2019 he put his family name on the door. Alexander Heating and Cooling LLC is family-owned and operated out of Charleston, and the name on the van is the name that answers for the work.

That accountability shows up in the reviews: a 5.0-star rating across 440+ of them, full of the same words — responsive, professional, fair. When you call, you get Chris and his crew, seven days a week.

Testimonials

What Your Neighbors Are Saying About Us

Owner Chris is super nice to work with and very responsive. Quote for a new HVAC was very reasonable, and came with nice warranties. When his crew installed it they were prompt, professional, protected our floors before starting the job, and took the time to answer our questions.

If I could give more than 5 stars, I would. Alexander Heating and Cooling are experts of their craft. Chris and his team have been servicing my house for years now and I’ve never had a bad experience. Recently we had to replace our entire HVAC system and the price was fair and the service was fast.

Excellent experience from start to finish. They responded extremely quickly when our AC stopped working, and the technician, Matt, was professional, knowledgeable, and took the time to explain everything clearly.

Today I had a new 2 stage HVAC system installed by Alexander Heating and Cooling. From the initial consultation to the final installation, Chris and crew were professional, knowledgeable, and easy to work with.

Outstanding Craftsmanship & Professionalism — Highest Recommendation. I recently had Alexander Heating & Cooling install an 18,000 BTU Mitsubishi mini split in my garage gym, and I cannot say enough about the quality of their work and professionalism from start to finish.
