"Plumber misdiagnosed the problem. I had to let him go as he was struggling to figure out problem and I had to hire another plumber. I paid In and Out for their time, even though problem wasn't solved. I won't use them again."

"When I needed to get a water heater replaced before a weekend after calling it on a Wednesday afternoon, they did it. Every other plumber called could barely send someone to give a quote! It can be hard to find a service company in San Francisco that behaves like they want your business so I was truly grateful. And while the job cost a lot more than I expected, they were able to help with the price because I was in a tight spot financially. Also, when I had an issue that I discovered later on with hot water not getting to the hydronic central heating, Adam came back to bleed the line when I was out of town! That's excellent customer service right there! They have a great team and they run a tight ship!"

FAQs for tankless water heater installation projects in San Francisco, CA

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
