A & A Plumbing

A&A Plumbing holds a 4.4-star rating across 15 homeowner reviews, positioning them among evaluated plumbers serving the greater Sunnyvale area. Established in 1947, this company has maintained continuous operations for over seven decades, expanding from its Sunnyvale base to serve communities including Palo Alto, Mountain View, Cupertino, and Santa Clara. Their status as the oldest plumbing company in Sunnyvale is reinforced by current licensure, with State License # 801323 confirming their bonded and insured standing.

The company distinguishes itself through specialized heating and cooling solutions, including geothermal systems and Mr. Slim ductless heating and air conditioning units, alongside traditional plumbing services. Their team holds factory training credentials and backs all work with a guarantee, while also maintaining certified backflow prevention testing authority for both Sunnyvale and San Jose jurisdictions. Active membership in the Better Business Bureau of Silicon Valley and the Sunnyvale Chamber of Commerce provides additional consumer protection and local accountability.
