Critical cooling for data center facilities
Chillers, critical HVAC, and occupied-facility retrofits for Metro Atlanta data centers — planned around uptime, not downtime.

Cooling failure is a facility problem — not an IT ticket. Willis Mechanical supports Metro Atlanta data center facilities with chiller plants, critical HVAC, and phased renovations in live halls. We work for facilities and ops buyers. We describe facility types only — never client names.
Why this market
- Uptime-critical cooling where a plant outage becomes a business outage
- Owner-occupied and operator facilities that need one accountable mechanical team
- Redundancy-minded work around live white space and support spaces
- Metro Atlanta response from crews who already understand critical-load environments
How we work in live environments
- Change windows planned with facilities and ops — not improvised shutdowns
- Assess plant capacity, redundancy, and end-of-life risk before recommending a path
- Phased renovations, retrofits, and special projects that keep critical loads online
- Clear documentation and one mechanical lead through service and project work
- Escalation from maintenance into a special project when another patch is not enough
Related systems
- Chillers — chilled-water plants and process/comfort cooling that protect the load
- HVAC — CRAC/CRAH-adjacent support, airside, and building mechanical systems
- Controls and reliability support when the plant and hall must stay coordinated
- Renovations & retrofits — capacity upgrades and replacements in occupied facilities, not ground-up construction
- Multi-location maintenance when you run more than one critical site
Chillers are not low-temp refrigeration. Data center cooling here means plant chillers and critical HVAC. If you need freezers, cold storage, or CO₂ racks, see Refrigeration — a related but different product.
Renovations, retrofits & special projects
Most data center mechanical work we do is in facilities that already run: plant upgrades, end-of-life replacements, and special projects scoped around change windows. We do not sell this as new construction.
Data centers FAQ
Do you publish data center client names?
No. We describe facility types and work — never client names on public pages.
Is data center cooling the same as refrigeration?
No. Data center work here is critical cooling — plant chillers and HVAC around live halls. Freezers and CO₂ racks are Refrigeration.
Can you do mechanical work without a long hall outage?
We plan renovations, retrofits, and special projects around change windows with facilities and ops — uptime first.
Who should call Willis for critical cooling?
Facilities and ops leaders responsible for Metro Atlanta data facilities who need one accountable mechanical team on chillers and HVAC.
