"Had a water heater go out on a Saturday. A friend of mine gave me Shane's contact information. He was out of town but sent Marco out to my home within 30 minutes of talking with him. Marco ended up installing the water heater first thing Monday morning after the part that was ordered didn't remedy the situation. Marco was pleasant, and effecient. He was concientious and went over usage with me afterwards. Shane was quick to stay in touch and follow up as well. Would highly recommend"

"The owner, Joe Ward, personally performed and oversaw all services alongside his team each day. He provided a fair and transparent estimate for the complete remodel, including a Tub-to-Shower conversion. With 35 years of experience, Joe inspired confidence in choosing him and his company for our project. His artistry and expertise were evident throughout the process, as he guided us in selecting options that resulted in a stunning and enduring design. Joe’s honesty and dedication shine through in his meticulous attention to detail, ensuring every aspect—from plumbing and electrical work to flooring and paint—meets his exacting standards without cutting any corners. He works exclusively with his trusted team, eliminating the need for unfamiliar contractors and maintaining consistency with the same crew each day, all led by Joe himself. Punctuality and communication were flawless, and his team treated our home with respect, thoroughly cleaning up at the end of each day. My trust in Joe is absolute, and I look forward to hiring him again for further updates to our over-100-year-old home. If I could, I’d gladly award him 1,000 stars! Thank you, Joe, for your exceptional work. We are in love with our bathroom and forever grateful we chose you!"

All American Home Remodeling, Inc. was founded by Chris King in late 2001 as a sole-proprietorship. On January 1, 2003, All American Home Remodeling became a Corporation. To date, the company has grown to consist of 11 full time employees (5 Project Managers / 4 Assistants), 1 Sales Consultant and an Office Assistant. The goal of All American Home Remodeling, Inc. is to keep the lines of communication between the remodeler and the home owner open so as to keep the flow of the job on schedule and so that the customer is 100% satisfied at the completion of the job. All American Home Remodeling's success is driven by reasonable pricing and quality work that is done in an efficient manner. The company prides itself in the excellent workmanship of the remodeling staff. This is proven by the number of repeat customers since the company's inception.

"We remodeled our kitchen and mudroom with All-American. Our experience was great from the beginning to the end! Chris gave us a quote that was reasonable and did his best to stick to it. Kelly helped us design our space and went through several drafts as our vision changed. This project took 3-4 months to complete and the guys on our team were reliable, honest, hardworking, polite and flexible. We have two young children and a neighborhood full of kids. The work was done during the summer and Chad, our team leader was so thoughtful and careful with the children who were around. All American uses their own staff for the whole job. Chad was there every day and saw our project from through to the end and Chris stopped in about weekly to check the progress. Chad had 15+ years of construction experience and it showed. All American uses the expertise of their staff as well, calling in specialists for plumbing, flooring and electric as needed. Chad was patient and willing to work with us to tweak our project as needed. He talked us through our options and guided us to local or online resources to select our materials. All American has good working relationships with local distributors demonstrating their professionalism as a business partner too. Our kitchen and mudroom turned out beautiful and transformed our spaces into rooms that are much more useful for our family."

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
