New systems sized right, installed clean, and backed by warranties.
Cooling
A new HVAC system is one of the biggest purchases you will make for your home, and the quality of the installation matters as much as the equipment. Alexander Heating & Cooling installs Heil systems across the Charleston area — sized to your actual home, installed by a crew our reviews describe as prompt and professional, and backed by warranties.
We measure instead of guessing. A right-sized system runs quieter, handles Lowcountry humidity better, and costs less to run.
One recent customer wrote that our crew "protected our floors before starting the job." That is the standard on every install.
Reviewers call our quotes "very reasonable." You see the full price and what it includes before anything is scheduled.

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.
Sizing the system to the house, not to the old label. Clean refrigerant and electrical connections. Charge set to manufacturer spec instead of eyeballed. Airflow verified room by room. And a walkthrough before we leave, so you know how to run the system and when to change filters. One customer recently had us install a two-stage system and described the whole process, from the first consultation to the final installation, as professional and easy to work with — that is the experience we aim for every time.
If your system is old, repairs are getting frequent, or the power bill keeps climbing while comfort drops, a new system usually pays for itself in lower bills and fewer breakdowns. Charleston heat also punishes worn-out or wrongly sized equipment harder than most climates. We will give you the repair number and the replacement number side by side, with no pressure either way.
