Expert Emergency HVAC Repair in Marin County, CA
When your heating or cooling system fails in Marin County, JM HVAC responds with emergency HVAC repair you can count on. We diagnose and fix the issues that stop systems cold: failed blower motors, refrigerant leaks, compressor failures, faulty ignition systems, clogged drain lines, and thermostat faults. Marin County homes range from mid-century Eichlers with radiant systems to hillside properties and older bungalows. Many run equipment that sees real stress from the county's coastal humidity and marine layer, which accelerates coil corrosion and strains components over time. We work on all system types, including forced-air furnaces, central AC, heat pumps, and ductless mini-splits. As a sole proprietor, JM HVAC means you get the same technician every visit, not a rotating crew. We assess your system, explain what failed and why, and repair it correctly the first time. Call JM HVAC when your system goes down and you need a licensed Marin County HVAC contractor on the job.
