Frequently Asked Questions
What size of commercial projects do you handle?
We focus on small to mid-size commercial projects — typically under 20,000 square feet. This includes single-tenant office fit-outs, dental and medical clinics, restaurant and café spaces, retail tenant improvements, and small standalone commercial buildings.
Do you design for restaurant kitchen ventilation?
Yes. Restaurant projects include commercial kitchen exhaust hood design, make-up air system coordination, and NFPA 96 compliance. We design the full mechanical system including kitchen exhaust, make-up air, and dining area HVAC in a coordinated package.
How is commercial HVAC design priced?
Commercial projects are priced by quote based on project size, complexity, number of spaces, and coordination requirements. Contact us with your architectural drawings and project description for a fixed-fee quote.
Can you coordinate with the electrical engineer on panel sizing?
Yes. We provide an electrical load summary for all HVAC equipment as part of the mechanical package. This gives your electrical engineer the data needed for panel sizing and circuit design.
