Claim This BusinessAbout Tankless Pro
Tankless Pro operates from Santa Clara, California, as a licensed and insured tankless water heater specialist serving the greater Bay Area. With a 4.8-star average drawn from 19 reviews, the company provides residential and commercial tankless water heater repair, replacement, and installation across cities including Santa Clara, San Jose, and Sunnyvale. Frank leads service delivery as the company's primary technician, handling everything from same-day replacements to complex warranty work on units including the Navien NPE 210S2. The team maintains 24/7 availability and uses high-quality materials on every installation to ensure system longevity.
What distinguishes Tankless Pro is their exclusive focus on tankless technology combined with brand partnerships across Navien, Noritz, Rinnai, and Rheem. Rather than serving every HVAC need, the company has concentrated expertise in on-demand water heating systems, including combi-boilers that handle both space heating and domestic hot water simultaneously. For Santa Clara homeowners considering radiant floor heating, Tankless Pro offers in-house design and installation of hydronic heating zones. Every technician completes an intensive training program, and the company stocks parts and labor pricing that reviewers consistently describe as transparent and below Bay Area market rates.
Customer reviews name Frank as the technician who handled their jobs, and those scenarios reveal the practical value of calling Tankless Pro. Jon Erickson needed a new Navien unit installed and found Frank's pricing beat other Bay Area contractors while still delivering knowledgeable installation. Wing Hui received a same-day quote rejecting an unnecessary recirculation pump, saving several hundred dollars on a Navien NPE 210S2 installation. When Jing Tu discovered a heat exchanger leak caused by a previous improper installation that voided the original warranty, Frank provided complete replacement with transparent pricing on both parts and labor across four competing bids. TG faced an urgent leaking water heater on a Wednesday morning and received a replacement by Thursday morning.
