About Nguyen Viet Hung

Beyond air conditioning, the company provides Heating Services, Furnace Services, and Heat Pumps, so one contractor can handle a system that switches between heating and cooling. Ductwork Services address leaks, poor airflow, and uneven room temperatures, while Thermostat Services cover installation, programming, and troubleshooting of controls that drive the whole system. Emergency HVAC calls are handled for urgent breakdowns, and Maintenance & Tune-up visits help catch worn belts, dirty coils, and low refrigerant before they become costly failures.

The company works within San Jose and nearby communities, where mild winters and hot, dry summers put steady demand on cooling equipment. Local familiarity helps the team plan visits efficiently and respond to the climate patterns that affect homes in the Bay Area.

Nguyen Viet Hung holds California state contractor license #1081497 and has been licensed since 2021, which gives customers a public record to verify. Anyone comparing local HVAC pros is encouraged to request written estimates, ask specific questions, and review credentials before deciding.
