Questions & Answers
Frequently
Asked Questions
Common questions about our services and process. If you don’t find what you’re looking for, call us at 707·252·7227.
What does a commercial HVAC retrofit involve?
A retrofit updates an existing system, such as aging rooftop units or outdated controls, without a full rebuild. We scope the real site conditions first and plan the work around your operating hours.
Can you replace a rooftop unit without closing my business?
We plan the crane lift, the swap and the commissioning around your hours so the disruption stays as small as the site allows.
Do you work with general contractors on new commercial builds?
Yes. We recommend calling before the plans are done, because the costliest mechanical problems are the ones built into the structure.
Is there a commercial HVAC company near me in Napa County?
Yes. We serve restaurants, tasting rooms, offices, tenant improvements, wine caves and commercial kitchens across Napa County.
How do you price commercial HVAC replacement?
You get a detailed scope and an honest written quote with a firm price, so there are no surprise change orders.
