About

Precision Mechanical Solutions, Inc. (PMSI) is a full-service commercial, industrial and institutional mechanical contractor headquartered in Fresno, California. Specializing in heavy-duty commercial HVAC, industrial refrigeration, steam boiler systems, hydronic piping and building automation systems (EMS), PMSI serves facility managers, plant directors and property owners across Fresno, Visalia, Madera, Tulare, Kings and Merced counties. We bridge high-level technical engineering with practical field execution, ensuring every commercial facility we service maintains maximum uptime, strict energy efficiency and total regulatory compliance.

Commercial HVAC and process cooling systems in Central California face extreme environmental demands, from triple-digit summer heatwaves to heavy airborne agricultural dust. Standard light-commercial approaches fall short under these harsh operational realities.

PMSI provides single-source accountability, offering end-to-end support that spans custom equipment installation, turnkey retrofits, rapid 24/7 emergency dispatch and tailored Planned Maintenance programs that protect capital assets over their entire operational lifespan.

Core Value Propositions And Competitive Differentiators

Facility directors rely on PMSI because we eliminate the risks, communication gaps and delays common with generic mechanical vendors:

160+ Years Of Combined Technical Mastery

Our operational team and field technicians bring over 160 years of combined mechanical experience to complex facility systems. Whether diagnosing parallel compressor rack pressures, troubleshooting digital automation networks or balancing multi-zone air handlers, our deep expertise ensures accurate root-cause resolution rather than temporary patches.

Union Craftsmanship (UA Local 246)

Every PMSI field technician undergoes rigorous, continuous apprenticeship and journeyman training through UA Local 246. This guarantees that your mechanical assets are handled by certified professionals adhering to strict state codes, OSHPD/HCAI healthcare standards and OSHA safety protocols.

Direct 24/7 Live Emergency Mobilization

Mechanical outages threaten revenue, inventory and tenant safety. PMSI operates a live, direct round-the-clock emergency dispatch line. When a critical boiler, chiller or cold storage system lock out occurs, our union technicians deploy immediately to stabilize your site and execute precision repairs.

Predictable Cost Control Through Planned Maintenance

We protect client bottom lines through structured preventative care that includes complete labor and parts coverage on maintainable components. Our proactive servicing slashes monthly energy consumption, reduces emergency service calls and delivers complete fiscal predictability for your operating budget.

Our Operational Values And Ethos

At PMSI, our business philosophy rests on straightforward operational principles designed to build lasting commercial partnerships:

• Integrity and Transparency — We communicate clearly, provide detailed diagnostic reporting and deliver upfront, honest pricing without hidden fees or unnecessary upsells.
• Quality Workmanship — We never cut corners on materials, safety limit checks or installation standards. Every weld, pipe fitting and wiring termination reflects union-grade quality.
• Accountability — We stand firmly behind our craftsmanship. Every new equipment installation is backed by our standard 90-day parts and labor warranty alongside a comprehensive 1-year conditional labor warranty.
• Client-Centric Reliability — We respect your operational schedule, coordinating heavy servicing, crane lifts and system cutovers during off-peak hours to ensure zero disruption to your core business.
