Building retrofits
Office, warehouse, light industrial, and institutional buildings — mechanical system overhauls that bring older buildings up to current efficiency and code.
Service
Project Work
Design-build retrofits, system upgrades, and tenant fit-outs delivered by tradespeople who'll be back to service the work after we leave. Built right, built once.
What we build
The kind of projects we take on.
Mid-sized commercial retrofit work where mechanical and controls expertise matters more than the lowest bid.
Tenant fit-outs
New tenant build-outs and reconfigurations — VAV layouts, dedicated cooling, controls zoning, and code-compliant ventilation.
System expansions
Adding capacity to existing chiller plants, boiler rooms, or air-side distribution — sizing, integration, and commissioning of the new work.
Process & specialty cooling
Server rooms, lab spaces, clean rooms, and process cooling loops — precision cooling and redundancy where it matters.
Energy upgrade projects
VFDs, ECM motors, controls optimization, and equipment right-sizing — utility-rebate-eligible work with measurable payback.
Controls upgrades
BAS conversions, sequence-of-operation rewrites, and graphics rebuilds — bringing your controls platform back into service.
Our process
How a project goes from idea to commissioning.
Walk & scope
We come look at the building, talk to your team, and understand what the actual problem is — not just what's been quoted to you.
Design & estimate
Engineering review, equipment selection, and a transparent estimate with line-item pricing — not a black-box lump sum.
Build
Self-performed install with our own technicians and pipefitters. Tight coordination with your operations team on access and downtime.
Commission & turn over
Functional testing, controls verification, as-built documentation, and operator training. The team who installed it stays available to service it.
Why FirstCall Austin
Project work backed by a service company.
A lot of contractors install and disappear. We're a service company first — which means the team that built your retrofit is also the team that maintains it. That alignment changes how we make decisions during the project.
We don't cut corners we'll have to live with for the next twenty years. We don't choose equipment we can't get parts for. And when something does need service down the road, the techs who installed it are still here.
- Self-performed labor — no rotating subcontractors
- Engineering-driven equipment selection
- Transparent, line-item estimates
- Direct accountability — one PM start to finish
- Long-term service relationship after handover
- Manufacturer-agnostic — equipment chosen on merit
