About Dantas Sergio

The work covers AC Services, Heating Services, Ductwork Services, Heat Pumps, Furnace Services, and Thermostat Services. Emergency HVAC calls and Maintenance & Tune-up visits are also part of the lineup.

Dantas Sergio holds California contractor license #1083833, issued through the state contractor registry, and has been licensed since 2021. Tustin residents can expect the same attention to detail whether the call is about a noisy blower motor, leaking ducts, or a thermostat that no longer holds its setpoint.

If you are comparing local HVAC pros, look for clear communication, a written estimate, and a willingness to explain what needs attention now versus what can wait. Dantas Sergio aims to offer exactly that for Tustin homeowners.
