Ongaro and Sons

What Ongaro and Sons does

Ongaro & Sons is a family-owned home services contractor founded in 1932 and headquartered in Petaluma, California. The company delivers HVAC, plumbing, electrical, and solar installation, repair, and maintenance services to residential homeowners and commercial customers across Marin, Sonoma, and Napa counties in Northern California, supported by three office locations (Petaluma, San Anselmo, Santa Rosa) and licensed, bonded, and insured field technicians. Its technical offering centers on industry-standard equipment from authorized-dealer partnerships with Trane (gas furnaces, heat pumps, air conditioning) and Mitsubishi (ductless mini-splits), augmented by SPAN smart-panel certification, EV charging station installation, whole-home rewiring, water heaters, boilers, radiant floor heating, hydro-jet drain cleaning, sewer and repiping services, and a recently added solar and battery-storage practice tied to California residential electrification.

The business generates revenue through six streams — HVAC services, plumbing services, electrical services, solar energy services, recurring maintenance-plan subscriptions, and an online store selling equipment, accessories, and service bookings on a Contractor Commerce platform. Pricing is predominantly project-based quotes after on-site evaluation, supplemented by promotional price points (e.g., $69 HVAC diagnostic, $700 off hydro-jet sewer cleaning) and third-party financing options; the maintenance-plan stream is the only subscription-priced line. Go-to-market is direct-to-consumer plus a dedicated commercial field-sales division, with leads sourced through 60+ localized SEO service-area pages, paid search and programmatic advertising, content marketing, referrals, social media, and an online booking and self-service estimate tool.

The company is privately held by the Ongaro family (Donald Ongaro and Ernest Ongaro listed as founders/owners), with no disclosed institutional investment, no funding history, and no M&A activity in the available data. It carries BBB A+, Diamond Certified elite status, Trane Comfort Specialist and PHCC credentials, and 2,705 Google reviews at a 4.8-star rating, and explicitly positions itself around California whole-home electrification, backup generation for PG&E public-safety shutoffs, and long-standing family-brand trust.
