About Hot Swap

Engineered for efficiency.
Backed by rebates.

Hot Swap is Southern California's Hot Water Heroes. We're a licensed C-10 electrical and C-36 plumbing contractor specializing in high-efficiency hot water solutions for homeowners, multifamily communities, and commercial properties. From same-day residential tank replacements to large-scale central plant upgrades, our team handles design, permitting, installation, rebates, financing, and ongoing support.

We work directly with TECH Clean California, SoCalGas, LADWP, SCE, SDG&E, PG&E, SMUD, and other utility programs to capture rebates that often cover most, sometimes all, of the equipment cost.
