What the reviews say
Water heater replacement & service
Reviewers praised clear upfront pricing for tankless service, same-day work after explaining what the water heaters needed, and prompt warranty service.
A 2026 BBB reviewer said an $18,000 tankless replacement quote was avoided with a $125 pump from another plumber. A 2026 complaint about a commercial-grade heater installed in place of the contracted model is 'Answered': the company said it was an upgraded residential unit at no extra cost. A 2025 invoice complaint was resolved after the company explained the charges.

BBB complaint
Customer name withheld · August 5, 2026 · Answered
The customer said a leaking heater was replaced with a commercial-grade unit rather than a residential one, that they could not reach the project manager for weeks, and asked for an exchange or refund of the difference and labor.
Company reply and outcome: On August 25, 2026, John Moore said the installed State unit was a residential upgrade at no added price because the contracted economy model was unavailable, and offered to install the original model once it is back in stock. BBB lists the status as Answered, not Resolved.
BBB complaint
Customer name withheld · December 19, 2025 · Resolved
A customer's spouse said the online invoice for a November 2025 water heater replacement did not match the $5,239.96 paid, alleging a $764.99 overcharge, and said a $149 check did not address it.
Company reply and outcome: John Moore said the signed estimate for the full job was $5,235.96, that staff had sent only the water heater portion of the invoice, and that the $149 was a membership cancellation refund. The customer accepted the explanation on December 22, 2025.
Ask before booking: Ask for the specific failed part and the repair cost next to any replacement quote, and confirm the exact heater brand and model in the contract.
