Industries: Commercial Building Upgrades
Cold Temp Solutions provides mechanical system upgrades for commercial office buildings, multi-tenant industrial complexes, retail centers, mixed-use developments, and institutional facilities across the San Francisco Bay Area and Northern California. Upgrade services cover rooftop unit (RTU) replacements, chiller plant modernization, cooling tower replacements, air handling unit (AHU) retrofits, building automation system (BAS) upgrades, variable frequency drive (VFD) installations on HVAC fans and pumps, refrigerant transitions from phased-out HFCs to lower-GWP alternatives, split system replacements, and heat pump conversions for buildings seeking to reduce natural gas dependency in alignment with California’s decarbonization goals. Cold Temp Solutions holds California CSLB license #1043411 under the C-20 Warm-Air Heating, Ventilating and Air-Conditioning classification and self-performs mechanical installation, refrigerant piping, and controls integration work — providing property owners and facility managers a single contractor accountable for design, permitting, installation, and commissioning of commercial mechanical system improvements.
Commercial mechanical system upgrades in California frequently qualify for financial incentives that reduce net project cost and improve return on investment for building owners and property management groups. Cold Temp Solutions evaluates PG&E Deemed Incentive program eligibility for qualifying HVAC equipment replacements — including high-efficiency rooftop units, VFD installations on AHU supply and return fans, electronically commutated (EC) motor retrofits, and economizer repair and recommissioning — and assists clients with incentive application documentation submitted to PG&E on the owner’s behalf. Equipment replacements must comply with California Title 24 Part 6 (California’s Building Energy Efficiency Standards) and, for systems using regulated refrigerants, the California Air Resources Board (CARB) HFC phasedown regulations and the federal American Innovation and Manufacturing (AIM) Act — which phase out high-GWP refrigerants including R-410A on an accelerating schedule through 2025 and 2026, creating mandatory replacement timelines for buildings with aging HVAC equipment that can no longer be legally recharged with phased-out refrigerants. Cold Temp Solutions quantifies projected annual energy cost savings and simple payback period for each proposed upgrade using facility-specific utility rate data and metered baseline consumption figures, giving ownership groups the financial data needed to prioritize capital improvements by return.
Cold Temp Solutions integrates upgraded HVAC equipment with building automation systems (BAS) using open-protocol platforms including Tridium Niagara N4, BACnet/IP, and Modbus TCP — enabling property managers to monitor energy consumption, equipment runtime, zone temperatures, and fault conditions from a centralized dashboard or remote access interface without dependency on proprietary vendor software. For multi-tenant commercial buildings, BAS integration supports tenant billing submetering, demand-controlled ventilation (DCV) tied to occupancy sensors to reduce outside air conditioning costs during low-occupancy periods, and automated after-hours HVAC scheduling that eliminates the energy waste of systems running at full capacity in unoccupied spaces. Commercial upgrade projects are completed for office buildings, Class A and B commercial real estate portfolios, light industrial and R&D facilities, retail centers, hospitality properties, and municipal and institutional buildings throughout Contra Costa, Alameda, Contra Costa, Santa Clara, San Mateo, Marin, Solano, and Sacramento counties. Property management companies overseeing multi-site Northern California HVAC fleets are encouraged to contact Cold Temp Solutions at (925) 374-4014 or inquiry@coldtemps.com to discuss a portfolio-wide mechanical assessment and upgrade program.
