Industries We Serve
Five Star Mechanical supports any commercial or industrial facility type across Western Washington. Rooftop units, storefront HVAC, restaurants, medical offices, warehouses, and multi-site operations. No residential work.
Commercial HVAC Support for Any Type of Business
Not every building runs the same. A restaurant HVAC issue is different from a medical office comfort complaint, and a warehouse rooftop unit failure is different from multi-tenant retail load balancing. We work across the full range of commercial environments and focus on two things: keep operations running and keep systems stable.
Our team services and installs commercial HVAC equipment, supports refrigeration where applicable, and delivers HVAC control systems and troubleshooting that modern facilities rely on. If it’s commercial, we can handle it.
Facility Types We Commonly Support
Retail & Storefronts
Comfort control, rooftop units, seasonal load issues, and multi-tenant balancing.
Restaurants & Food Service
Dining comfort, kitchen heat loads, airflow issues, and reliable cooling during peak.
Medical & Dental
Stable temperatures, zoning, patient comfort, and dependable system uptime.
Professional Offices
Law firms, accounting, and general offices needing quiet, stable comfort.
Warehouses & Distribution
Large-volume conditioning, rooftop units, dock areas, and airflow management.
Industrial & Manufacturing
Process-adjacent HVAC needs, reliability focus, and controls coordination.
Don’t see your facility type listed? That’s fine. This is a hub, not a limitation. If it’s commercial or industrial, we can support it. Call (253) 852‑8284.
What We Do Across These Industries
Commercial HVAC is rarely “one thing.” Most facilities need a contractor that can handle day-to-day service, planned maintenance, targeted equipment replacement, and performance troubleshooting when comfort complaints or energy costs spike.

HVAC Control Systems Matter in Every Industry
Controls and automation are a major part of modern commercial HVAC performance. If scheduling, zoning, sensors, or equipment communication is off, the building suffers. We support control system troubleshooting, stabilization, and upgrades so facilities run reliably and efficiently.
This applies to every facility type: storefronts, restaurants, medical offices, law firms, warehouses, and industrial sites. Controls are where comfort, energy, and uptime either work together or fall apart.
