What Is Commercial HVAC?
Commercial HVAC covers the heating, ventilation, and air conditioning systems used in commercial buildings — offices, retail spaces, restaurants, warehouses, medical offices, and multi-tenant properties. These systems are typically larger and more complex than residential systems, with different equipment types, controls, and code requirements.
When to call EVS:
- You're building out or renovating a commercial space
- Your existing commercial HVAC system needs repair
- You want a scheduled maintenance program for your business
- Your energy bills are high and you want an efficiency assessment
- You need prompt service to avoid business disruption
- Your tenants are complaining about temperature issues
Who this is for: Business owners and property managers in Santa Clara, San Jose, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Santa Cruz, Cupertino, Campbell, Saratoga, Los Altos, and Milpitas. Light commercial properties.
Why EVS?
Same family-run service, commercial scale.
The same team that does residential work in Santa Clara handles commercial projects. You get the same quality, attention to detail, and personal accountability.
Prompt service for businesses.
Downtime costs money. When a commercial system fails, we prioritize getting it running. 1-2 hour callback. Same-day service when possible.
Permits handled.
Commercial HVAC permits are more involved than residential. EVS handles the full process — permit application, scheduling, inspection coordination.
Proper load calculations.
We size commercial systems properly — not by square footage rules of thumb. This matters more for commercial because the cost of a wrong-sized system is higher (both in energy waste and comfort complaints).
Brands with commercial support networks.
Carrier, Bryant, Daikin, Lennox, Goodman. If it has commercial warranty service in the Bay Area, we install it.
No subcontractors.
EVS doesn't subcontract commercial work. The same Euler Vargas that oversees residential installations oversees commercial jobs.
