About Restart HVAC
Restart HVAC operates as a licensed heating and cooling contractor serving Mountain View and the broader Silicon Valley region, including Palo Alto, Sunnyvale, and Santa Clara. Founded to address the area's unique climate demands, from chilly winter nights to scorching summer heat waves, the company has built a reputation over several years through 66 verified customer reviews that collectively award them a 4.7-star rating. Georgy leads a crew of credentialed technicians who handle everything from heat pump installations to furnace repairs, maintaining transparent pricing and clear communication throughout each service call.
What distinguishes Restart HVAC from neighboring contractors is their specialization in heat pump technology and their willingness to tackle complex configurations that other local companies decline. They install Mitsubishi variable-speed heat pump systems and heat pump water heaters (HPWH), offering homeowners in California access to state rebate programs for energy-efficient upgrades. Their expertise extends into commercial refrigeration, servicing walk-in coolers, wine storage units, and restaurant freezer systems, a niche that requires specialized training beyond standard residential HVAC work. The company provides detailed quotes that break down costs before any work begins, and they handle city inspection paperwork for customers.
Customer stories reveal the hands-on approach that defines this shop. When Juergen Pfaff's Mitsubishi system presented configuration challenges during installation, Georgy's team resolved every issue professionally. Julie Q received the most detailed quote among three competitors, and her installation completed ahead of schedule, passing city inspection without complications. Anil Patel needed urgent furnace repair after PG&E identified a malfunctioning burner, Georgy arrived the next day in a fully-equipped van, completing the fix on the first visit. The consistent thread across reviews: technicians who show up on time, explain options clearly, and stay until the problem is solved.
What Customers Say
5-star ratings dominate the 66 reviews, with heat pump installations and heat pump water heaters appearing frequently.

Multiple reviewers highlight same-day or next-day response times, and no negative reviews were identified in the sample.
