Our Commercial HVAC Solutions

Commercial heating and air‑conditioning systems are very different from their residential counterparts. They are larger and more complex because they must heat and cool large facilities and often accommodate multiple zones or thermostat settings. Whereas a homeowner might have a single stand‑alone unit tucked along the side of the house, a commercial building may need a rooftop unit capable of conditioning hundreds of square feet. These systems are built as modular packaged units, meaning components can be added or removed to adjust capacity. Because of their size and complexity, commercial units require professional installation and regular maintenance; neglecting maintenance can lead to costly failures. In California’s Tri‑Valley region, summer heat often exceeds 100 °F and winters bring cool, wet storms.

HR&M’s technicians specialize in commercial HVAC design, installation and maintenance. We work with packaged rooftop systems, split systems, and ductless mini‑splits sized for offices, retail spaces, wineries and warehouses. Our services include:

  • System design and installation – We assess your building’s size, occupancy and usage patterns to recommend the right equipment. Modular commercial units allow us to tailor capacity; we can add or remove components as your business grows.

  • Preventative maintenance – Routine inspections and tune‑ups keep compressors, fans and coils operating efficiently. Maintaining large commercial systems prevents downtime and reduces energy costs.

  • Repairs and upgrades – When equipment fails, HR&M’s licensed technicians respond quickly to get your system back online. We can upgrade older units to higher‑efficiency models, integrate smart thermostats and implement energy‑saving controls.

  • Indoor air quality – For offices and labs we provide filtration upgrades, ventilation improvements and humidity control. Balanced ventilation is especially important in wine tasting rooms and research facilities.

 

Whether you operate a winery in Livermore or a corporate office in San Ramon, HR&M ensures your commercial HVAC system meets local building codes and delivers reliable comfort year‑round.

Josh installed a cooling system in our wine seller and then a new air conditioning system in our house. He was great, professional, clean and put up with our uncooperative dog, always with a great attitue. The units work great and highly, highly recommend him.

Josh was extremely timely in his response to my repair request. He did a wonderful job diagnosing the issue, and quickly had our system back up and running. I would definitely use him again in the future.
