Hydro Furnace Service & Installation

Why neighbors call Lutz
We've been doing this in San Francisco since 1929. Over the decades we've learned that the best plumbing service has less to do with clever marketing and more to do with showing up on time, diagnosing honestly, and doing the work right the first time.
Every Hydro Furnaces job we take on comes with our craftsmanship warranty, fully licensed technicians, and transparent pricing. If you've been burned by the industry before, we hope we'll be the company that restores your faith in it.

Common questions
How quickly can you get here?
It depends on crew availability, so Lutz Plumbing does not promise a set arrival time in San Francisco. Call (415) 621-4292 Monday to Friday, 8:00 AM to 4:30 PM, and the dispatcher quotes a realistic arrival window. If it is urgent, call rather than requesting online. After hours, leave a voicemail and a dispatcher calls back for genuine emergencies.
Do you handle permits?
Yes. Every job that requires a permit is permitted by us, signed off by DBI or SFPUC as appropriate, and the paperwork is handed to you when we are done.
What is your warranty?
Lutz Plumbing covers its workmanship on every hydro furnaces job with a signed warranty: if the work is not right, we come back. We also handle most manufacturer warranty claims on your behalf for the equipment we install.
