About Guido's Service

The company offers AC Services, Heating Services, Ductwork Services, Heat Pumps, Furnace Services, Thermostat Services, Emergency HVAC, and Maintenance & Tune-up. In practice, that might mean tracing why a cooling system keeps shutting off, inspecting a furnace's burners and ignition, sealing leaks in ductwork that wastes conditioned air, or installing a thermostat that runs equipment on schedule. A maintenance visit typically involves cleaning, testing, and checking for worn parts before they fail in the middle of a season.

Guido's Service has held California contractor license #892930 since 2007, which gives it more than 19 years in the trade. Vallejo's weather can swing from cool, foggy mornings to hot afternoons, so familiarity with local conditions helps when a system is being serviced, repaired, or evaluated for replacement.
