# Maxx Water Heater Service

_Company profile on San Diego Water Heater Guide — verified 2026-06-10._

Maxx Water Heater Service is a small San Diego water heater operation on a verified C-36 Plumbing license issued in 2015, serving inland and north-city ZIP codes it lists explicitly — Rancho Peñasquitos, Carmel Valley, Poway, Rancho Bernardo, Scripps Ranch and neighbors. It advertises same-day installation and repair, free in-home estimates, Saturday hours, and installs Rheem, A.O. Smith, and Bradford White equipment. CSLB shows a current no-employees workers'-compensation exemption, which is worth understanding before booking.
