Frequently asked
How does Title 24 affect commercial HVAC?
Title 24 sets minimum efficiency, sizing, and control requirements for commercial systems in California. Documentation has to match the installed system — failed documentation can hold up the certificate of occupancy. We handle it as part of every commercial project.
Do you coordinate with our general contractor?
Yes. We work with the GC, architect, electrician, and roofer as needed. Design-build for the HVAC scope does not mean we do not collaborate with your other trades.
