HVAC maintenance, repair, and replacement
Commercial and industrial HVAC — planned maintenance, fast repairs, and equipment replacement that keep facilities online. Separate from refrigeration.
When comfort and air systems fail, you need a crew that shows up and finishes. Willis Mechanical services, repairs, and replaces commercial and industrial HVAC across Metro Atlanta — from a single rooftop call to multi-unit support — without treating HVAC as the same discipline as refrigeration or chillers.
This page is HVAC — not refrigeration or chillers. For cold rooms, freezers, food process, and CO₂ racks, see Refrigeration. For chilled-water plants and process loops, see Chillers.

Renovations, retrofits & special projects
HVAC work often grows into phased renovations and retrofits in facilities that already run: unit replacements, zone upgrades, and special projects scoped around uptime. We are not framing this as ground-up construction — we work the systems owners already operate.
