Water Heater Installation & Replacement in La Mirada & Norwalk
Power Pro Plumbing, Heating & Air installs and replaces water heaters across La Mirada, Norwalk, and greater LA and Orange County, handling seismic strapping, proper venting, drip pans, and temperature-pressure relief to California code.
Choosing the new unit is where we earn our keep. Size it to your household's actual hot water habits (too small means cold showers; too big wastes energy every day), pick the right fuel and efficiency tier, and decide between a traditional tank and a tankless upgrade. We'll lay out the options with honest math, including any current SoCalGas rebates on qualifying high-efficiency units.
Every installation includes haul-away of the old unit and a full system test. Right now, new water heater installations come with a 10-year warranty for the price of 6 — and free water quality testing with any water heater service or installation.
Current special: 10-year warranty for the price of 6 — residential only, expires 12/31/26. See all specials
What are the signs your water heater needs replacing?
Replace your water heater when you see these signs, before it fails, not after it floods:
- Age past 8–12 years for tank units — check the serial number if you're not sure
- Rusty or brown hot water: the tank is corroding from inside
- Metallic-smelling or tasting hot water
- Pops, cracks, and banging from sediment and loose components
- Water pooling under the unit — failure is close
- Repairs piling up on a unit near end of life
How do you choose the right replacement water heater?
The right replacement water heater comes down to four decisions:
- Type: traditional tanks cost less upfront and suit heavy simultaneous use; tankless units deliver endless hot water, save space, and last far longer
- Fuel: gas is typically cheapest to operate here; electric and heat pump water heaters fit all-electric homes (LADWP customers may qualify for rebates up to $2,500 on qualifying heat pump water heaters)
- Size: household size, peak usage, and fixture count set the capacity — we calculate it rather than guessing
- Efficiency: higher-efficiency units cost more upfront but repay it monthly; qualifying models can earn utility rebates
What does California code require for water heater installs?
Water heater installation in earthquake country carries requirements many quick-swap outfits skip: seismic strapping (required by California code), proper combustion venting, drip pan and drain line where needed, expansion tank requirements, and gas line sizing verification. Cutting those corners risks more than a failed inspection — it risks your home. Our installations are permitted, code-compliant, and tested end to end.
Water Heater Installation & Replacement FAQs
How long does water heater replacement take? +
A straightforward like-for-like swap typically takes two to four hours including haul-away and testing. Conversions — tank to tankless, or relocations — take longer and get an accurate timeline in the estimate.
What size water heater do I need? +
For tanks, it's driven by household size and peak usage — a family of four typically lands in the 40–50 gallon range, adjusted for habits like back-to-back showers or large tubs. For tankless, we size by flow rate and temperature rise instead. We'll calculate it properly during your free estimate.
Is there a deal on new water heater installations? +
Yes — currently a 10-year warranty for the price of 6 on new water heater installations, plus free water quality testing with any water heater service or installation (residential only; offers can't be combined; expire 12/31/26).
Should I switch to tankless when I replace? +
If you value endless hot water, space savings, and a 20+ year lifespan, it's worth pricing — and qualifying ENERGY STAR gas tankless units can earn SoCalGas rebates up to $1,500. The conversion involves gas line and venting work, so get a real estimate rather than a guess; we'll quote both paths.
