Same-Day Emergency HVAC in St. Helena

When cooling dies during a heat wave or heat quits on a cold night, waiting three days isn't an option. JVG offers same-day emergency response for St. Helena — call or text (707) 531-9216 and a real person answers, Mon-Sat 7am to 7pm. Emergencies move to the front of the line.

With up-valley summers that run hotter than Napa proper, we know which failures can't wait: homes with elderly family members, infants, or medical needs get priority, period. Our trucks carry the common failure parts — capacitors, contactors, ignitors, flame sensors, fan motors — so most emergency calls end with the system running the same visit.

Emergency work gets the same honesty as scheduled work: diagnosis explained, price in writing before repair, and no crisis upselling. Being a Napa-based family team, we're straight with you about arrival windows for St. Helena — and we keep them.
