American Kitchen and Bath, Inc. is a reputable full-service General Contracting business based out of San Jose, CA. We specialize in kitchen and bathroom remodeling. We not only design your kitchen and bathroom, we handle the entire project while offering innovative ideas and creative design solutions. Contractor's License #886059

"American Kitchen and Bath, Inc. completed my contracted improvements on time and within budget. And that’s what would be expected. Yes, I would recommend them. AKB went beyond the normal expectations. My project required a whole house renovation. It included replacing the electrical, plumbing, windows, flooring and interior and exterior paint along with a completely new kitchen and bathroom. I found AKB by reviewing the City of San Jose permit website and saw they had pulled more permits than other local firms listed in National Association of Remodeling Industry (NARI). I completed an online contact request, and Shawn responded within the hour. We made an appointment to discuss what I wanted and was assured they could do the work within the budget. The process of developing the scope of work was very detailed. There were a few subcontractors necessary for my project, and I was introduced to each contractor at this early stage. I could tell from these meetings that the contractors had a very good relationship with AKB. It also involved working very closely with their designer, Buffy. I had no vision as to what I wanted, but Buffy was able to tease out what I did not like. In no time, she knew exactly what would appeal to my taste. Both Shawn and Buffy remained part of my project all the way through to the finish. When the project started, the demolition, installing a beam, rough plumbing and electrical all moved along very quickly. We were scheduled for the first city inspection when the pandemic shelter-in-place order was given. I was reassured by Johans, the owner, that the minute the business was released from the shutdown, my project would proceed. After the shutdown and passing that first inspection, the work progressed at an amazing rate. The site supervisor, Ron, would save up all of his questions for our Friday meetings as well as email or texting which would allow me to make necessary decisions quickly. They made sure that every decision I made was followed. There was a great deal of plaster and drywall patching, interior and exterior trim work, refinishing of doors, and many other finishing touches that needed to be done. Ron made sure each detail was completed with care and craftsmanship. The quality of the work was exceptional. All AKB employees and subcontractors were very responsive and respectful of my house as well as my time. At the first meeting with Buffy at my house, she called my house a “gem.” The finished project is better than I could imagine. I was promised a new beautiful home and now have my dream home, my gem."

"Vincent and his assistant Sergei took on a difficult job of installing a stove top and a downdraft fan that posed some challenges of fitting into an existing counter space. An installer sent by the dealer failed at this task but they were careful and creative in finding solutions. We appreciated the attention to detail and their hard work - and the result was fabulous. Not least, the price was reasonable and both of them were easy and pleasant to work with. No hesitation in recommending their services."

FAQs for tankless water heater installation projects in San Jose, 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.
