71 Commercial HVAC Contractors in Greenville, SC

Greenville’s position in the Carolina Piedmont shapes steady commercial demand: summers hit about 90°F with 65% humidity for roughly 50 days, while the Blue Ridge foothills can usher in cooling breezes that shorten heat waves. Winters average 33°F lows and occasional ice storms stress backup heat. That mixed climate favors heat pumps and drives work for 16 contractors in the area — average rating 4.7 from 3,531 reviews, seven offering 24/7 service for urgent commercial-hvac Greenville needs.

Project costs vary widely with building size, system capacity, and retrofit complexity; major cost drivers include the rooftop unit or heat pump, controls and zoning, ductwork or piping modifications, electrical upgrades and permitting, plus labor and testing. For commercial projects in South Carolina you should confirm the installer holds a Mechanical Contractor (Group 2 — HVAC) license from the South Carolina Contractor’s Licensing Board, and ask for proof of insurance and any manufacturer-authorized installation credentials.
