HVAC retrofitting services near me

Chillers are the backbone of large-scale cooling for commercial buildings, hospitals, data centers, and manufacturing facilities. At Dormatech Mechanical Systems, we specialize in all types of chiller systems, including air-cooled, centrifugal, magnetic bearing, absorption, and low/high pressure chillers. We also have dedicated expertise in MRI and radiation chiller systems, which require precise temperature control for medical imaging equipment.

Our comprehensive chiller services start with a thorough inspection and condition assessment. We perform tear-downs and open inspections to identify internal wear, corrosion, or component failure. Our predictive and preventative maintenance includes vibration analysis, oil and refrigerant analysis, and eddy current testing of tubes. We also offer tube and coil cleaning to restore heat transfer efficiency, and we handle start-up and commissioning for new installations. For facility teams, we provide owner's training to ensure your staff understands system operation and basic troubleshooting.

Why choose Dormatech? We are SBA certified, Title 24 certified, and registered with the CA Department of General Services. Our technicians are members of local UA unions 342, 343, 393, 467, and 38, and we adhere to MSCA standards. When you need reliable chiller performance in Northern California, our 24/7 emergency service means you're never left without cooling.

Packaged rooftop units (RTUs) are a common sight on retail centers, office buildings, shopping centers, and light commercial properties. Dormatech Mechanical Systems provides expert installation, repair, and maintenance for all major brands of RTUs, box cars, air-handling equipment, make-up air units, split systems, fan coils, and water source heat pumps. We understand that a broken RTU can mean lost revenue, uncomfortable customers, and even health code issues for restaurants or clinics.

Our process begins with a detailed diagnostic to pinpoint electrical, refrigeration, or airflow issues. We then provide a transparent repair or replacement recommendation. For new construction or retrofits, we handle custom design, ductwork installation and fabrication, humidification, indoor air quality upgrades, and tenant improvements. We also specialize in change-outs and retrofits that improve energy efficiency without requiring a full building overhaul.

What sets us apart is our commitment to ongoing performance. We offer start-up and commissioning services, plus owner's training so your team knows how to operate the system for maximum efficiency. Serving everything from high-rise buildings to sports arenas and research labs in Northern California, we bring the same level of attention to every RTU, big or small. And with 24/7 emergency availability, we're always just a phone call away.

Beyond traditional HVAC, Dormatech Mechanical Systems has deep expertise in a wide range of mechanical and specialty equipment. We service VRF/VRV systems (variable refrigerant flow), ABB drives, steam line repairs, compressor rebuilds, air compressors, steam boilers, boilers and furnaces, fan walls, variable frequency drives (VFDs), power exhaust fans, vane axial fans, pumps, actuators, dampers, and valves. This diverse capability makes us a one-stop solution for industrial and commercial facilities in Northern California.

Each piece of equipment requires specialized knowledge. For example, our compressor rebuild service can extend the life of a semi-hermetic or scroll compressor at a fraction of replacement cost. Our steam boiler repairs include tube replacement, burner tuning, and water level control troubleshooting. For fan walls and vane axial fans, we perform vibration balancing, bearing replacement, and motor testing. We also handle VFD programming and actuator calibration to ensure your mechanical systems respond correctly to building automation demands.

Our team is trained on major brands and follows all safety and code regulations, including Title 24 and Dept. of Industrial Relations standards. Whether you need a quick actuator swap or a complete steam line overhaul, we provide detailed estimates, clean workmanship, and post-service follow-up. With certifications including DGS and SBA, plus union affiliations, you can trust Dormatech for any mechanical or specialty equipment need in Northern California. Call our 24/7 emergency line anytime.
