What to know in Aliso Viejo

The Aliso Viejo housing picture

Sized to your household, installed to code — not just swapped

Most water heater 'installs' are swaps: same size tank, same old shortcuts, new sticker. We treat replacement as the one moment everything gets corrected — seismic strapping, venting, combustion air, drainage, gas line condition — because those details are cheap to fix during an install and expensive to discover during a home sale or an insurance claim. Sizing starts with how your household actually uses hot water: a two-person home and a five-person home with teenagers are different projects, and back-to-back showers going cold is a design failure, not a lifestyle problem. We'll walk the honest math on tank versus tankless versus heat pump water heaters — including which rebates apply — and Rheem warranty registration is handled for you before we leave.
