Commercial HVAC Services in the Bay Area
At B.A. Morrison Heating, Air Conditioning & General Contractor, we provide dependable, high-quality commercial HVAC services for businesses, property managers, general contractors, and building owners throughout the Bay Area. As both a licensed HVAC company and General Contractor, we are a true one-stop shop—handling everything from equipment installation to structural work, roof penetrations, patching, and finish work using our own employees.
This allows us to streamline projects, reduce downtime, and eliminate the need for multiple subcontractors.
Complete Commercial HVAC System Installation
We provide full commercial HVAC installation for new construction, tenant improvements, remodels, and system upgrades. Our team ensures each system is correctly sized, energy-efficient, and tailored to the needs of offices, retail buildings, warehouses, restaurants, and industrial facilities.
Package Unit Changeouts (2–25 Ton)
We specialize in 2-ton to 25-ton package unit replacements, including rooftop and ground-mounted systems. Our team manages equipment removal, installation, curb work, electrical and gas reconnections, and full system testing—minimizing disruption to your business.
General Contractor Services for HVAC Projects
As a licensed General Contractor, we provide structural and building services that most HVAC companies cannot, including:
- Equipment Platforms & Structural Support:
We design and build custom platforms for rooftop units, mini-splits, condensers, and other commercial HVAC equipment. Our platforms provide proper clearance, support, and accessibility for future service and replacement. - Roof Penetrations for HVAC & Ductwork:
We perform roof penetrations for package units, ductwork, electrical, refrigerant lines, and exhaust systems. Our team ensures all penetrations are flashed, sealed, and installed to code. - Future-Ready Installations:
We build equipment mounts, ducts, and roof openings designed to make future replacements easier without requiring roofing repairs—saving your business long-term costs. - Patching, Repairs & Finish Work:
All patching, sealing, carpentry, and finish work is done by our own employees, ensuring consistent quality and seamless project management. - No subcontractors. No delays. One point of contact. One-stop shop.
Rooftop Ductwork Installation & Replacement
We design, fabricate, and install commercial rooftop ductwork, ensuring efficient airflow and long-lasting durability. All work meets current codes and performance standards.
Because we are a GC, we can also perform any required roof framing, reinforcement, or patching.
Ductless Mini-Split System Installation
We install and service ductless mini-split systems ideal for offices, IT rooms, retail areas, tenant spaces, and commercial add-ons. Mini-splits offer zone control, energy savings, and flexible installation options where ductwork isn’t feasible.
Exhaust Fan Installation & Replacement
We install and replace commercial exhaust fans for kitchens, warehouses, restrooms, and mechanical rooms. Proper ventilation improves air quality, reduces heat, and ensures compliance with safety standards.
Swamp Cooler Installation & Service
We provide evaporative cooler installation, replacement, and maintenance for large commercial and industrial facilities—an energy-efficient solution for high-volume cooling needs.
HVAC Equipment & Ductwork Removal for Reroofing
When your building needs a reroof, we handle the complete removal and reinstallation of HVAC equipment and ductwork.
Because we are a General Contractor, we also manage:
- Roof openings and penetrations
- Patchwork
- Flashing and sealing
- Finish work
- Ensuring HVAC and roofing components integrate correctly
This ensures a smoother reroofing project with fewer contractors and no gaps in responsibility.
