What we do
Complete mobile climate control service
From a reefer that won't pull down to a bus with no A/C — one call covers diagnostics, parts, and repair.
Preventive Maintenance
Scheduled PM programs, pre-trip inspections, belt and filter service, and controller updates that catch failures before they become spoiled loads.
Bus & Fleet HVAC
Heating and air conditioning for transit buses, shuttles, work trucks, and fleet vehicles. Leak detection, compressor replacement, and full system recharges.
Tesla A/C Service
Mobile A/C and heat pump service for Tesla Model S, 3, X, Y and Cybertruck — no cooling, weak airflow, refrigerant leaks, electric compressor and octovalve faults, cabin filter service. Plus other EVs and hybrids.
Controller Diagnostics & Software
Deep diagnostics on APX, Advance, and legacy controllers — alarm history, data downloads, firmware updates, and configuration of setpoints and modes.

About us
Independent, technical, and hands-on.
Mobile Climate Control Services is an independent transport refrigeration and mobile HVAC service company. We spend our days inside Carrier and Thermo King units, Tesla and EV thermal systems, fleet HVAC, and the electronics that run them — so when something goes wrong, we've usually seen it before.
We work with owner-operators, regional carriers, food distributors, and transit fleets who need a service partner that shows up, fixes it right, and explains what happened.
Service area & reviews
Covering the whole Bay Area, 24/7
North Bay to South Bay, Peninsula to East Bay — and beyond on request.
