Charleston air is beautiful outside. Inside, it takes some help.
Air & Water
Lowcountry living means humidity, pollen seasons that coat everything in yellow, and homes sealed tight against the heat — which traps all of it inside. Alexander Heating & Cooling helps Charleston homeowners breathe easier with better filtration, humidity control, and smarter command of the whole system.
Better filtration means less of the Lowcountry spring ends up circulating through your bedrooms.
Sticky indoor air is more than uncomfortable — it feeds musty smells. We help your system wring the moisture out.
Smart thermostats let you run the house from your phone and keep an eye on humidity even when you are away.

How It Works
Give us a call at (843) 608-1689 or fill out the form. We will ask a few questions about what is going on.
Our technician finds the real problem and gives you clear pricing before any work starts.
We finish the job, clean up after ourselves, and test everything before we leave. Done means done.
The same humidity that makes August afternoons heavy works on the inside of your house all year. When a system is oversized or worn, it cools the air without pulling enough moisture out — and damp indoor air is what musty closets, swollen doors, and allergy flare-ups have in common. The fix usually is not a gadget; it is a system that is sized, tuned, and controlled correctly, with the right filtration behind it.
A smart thermostat is the simplest air-quality upgrade there is. Set schedules, watch the humidity, and adjust the house from the beach or the office. We install and configure them as part of many of our installations — wired correctly for heat pumps and multi-stage equipment, which is where do-it-yourself installs usually go wrong.
