Commercial HVAC for offices, retail, schools and small commercial buildings
We repair, install and maintain commercial air conditioning across Stockton, Sacramento and Modesto, including rooftop units, ductless mini-splits and VRF systems. Same licensed technicians, same upfront pricing.
Commercial HVAC services cover the repair, installation and planned maintenance of the heating and cooling systems in a business property. RB HVAC Inc. works on rooftop units, ductless mini-splits, VRF systems, central air and heat pumps for offices, retail stores, small commercial buildings, schools and churches across Stockton, Sacramento and Modesto. We work from the same operation as our residential team, so you get the same upfront pricing, the same written proposal and the same 24/7 emergency response.
Everything this service includes
Rooftop units
We install and service packaged rooftop units, the most common commercial system on low-rise buildings.
Ductless mini-splits
Comfort for buildings with no existing ductwork, and for individual zones or additions.
VRF systems
Multi-zone commercial systems for accurate control across a building.
Preventative maintenance
Planned service programmes for business customers, so a failure does not become a closure.
Commercial AC repair
Emergency and planned repair across all the systems above, with the price agreed before we start.
Mixed occupancy
Offices, retail stores, rental properties, small commercial buildings, schools and churches.
How the job runs
The same four steps whether it is a repair, a replacement or a seasonal tune-up.
We look at the equipment, the controls, the ductwork and the loads, and we listen to how the space is actually used.
Options and costs laid out plainly, with the maintenance implications of each one.
Scheduled to suit your operating hours wherever the work allows, because a closed shop is its own emergency.
A service programme so the system stays inside its efficiency band and does not fail on a trading day.
