United HVAC, Plumbing & Electrical

United HVAC, Plumbing & Electrical has earned a 4.9-star average across 856 reviews while serving Cupertino and the wider Bay Area for more than 25 years. The company holds active contractor licenses and insures every technician dispatched to a residential service call. Extended weekday and weekend hours run from 7 AM to 10 PM, and the team fields a live on-call rotation for pipe bursts, gas leaks, and full HVAC emergencies outside standard business hours.

This contractor has built a specialty around whole-home system conversions, including swapping aging gas water heaters for electric hybrid heat pump units before California appliance deadlines arrive. A membership program bundles priority scheduling, periodic maintenance reminders, and discounted service rates for enrolled homeowners, with one Cupertino reviewer crediting the program for streamlining a multi-phase ductwork overhaul that required coordination with a licensed asbestos abatement crew.

Customer reviews repeatedly call out named technicians for one-on-one project execution. Max Aiusha handled a water heater and water softener installation inside a 1961 home where he routed new piping around structural studs and coordinated extra monitoring hardware without cutting load-bearing members. Rinat followed up on the same property to install a pressure-reducing valve, an auto-shutoff sensor, and a reverse-osmosis filtration loop while replacing original cast-iron drain lines. Program manager Tim managed the full bidding and permitting timeline for an HVAC ductwork replacement, arranging a certified C-22 asbestos removal step before the new ductwork went in, and at least one reviewer subsequently enrolled in the company membership as a direct result of that experience.
