Commercial HVAC in Charleston: how the building changes the job
The equipment is often the same. The use is what changes. An office needs its schedule to match real hours. A shop lets in humid air every time the door opens. A restaurant's hood pulls air from the room, so comfort depends on air balance. A church sits quiet all week and then fills at once. Tell us how the space gets used, because that shapes the diagnosis.
A church or meeting hall may sit empty most of the week and fill all at once, so a single schedule rarely fits. Tell us how the building is used on its busiest day.
Before you hire a commercial HVAC contractor
Settle three things first. Read your lease and know who pays. Find out who holds the keys and how the equipment is reached. Then check any contractor's license through the state, since LLR's Contractor's Licensing Board oversees commercial mechanical work. Planning a new unit? Our rooftop replacement guide explains the steps.

Questions about this service
What size of commercial building do you work on?
Light commercial. That means offices, retail, restaurants, churches and small multi-tenant buildings running package units, split systems or ductless systems. Our pages do not cover chillers, cooling towers or boiler plants. Tell us about your Charleston building and the equipment it uses, and we will say plainly whether it fits.
Do you serve homes as well as businesses?
Yes. Aero Air Techs serves homes and small businesses around Charleston. The trade work is similar, though access, approvals and timing differ on a commercial job. Tell us who approves repairs and when the space is empty, so the visit and the quote fit how your business runs.
How do I choose a commercial HVAC contractor?
Get the license number and run it through the SC LLR lookup, since LLR's Contractor's Licensing Board oversees commercial mechanical work. Then ask for a written scope and recent reviews from any company you consider. Our contractor guide has the full list of questions for Charleston owners.
