"They tried to charge my dad $440 and replace the pipes for the sink. They initially told me $79 over the phone. The pipes did not need replacing, and he called someone else to do the job. Never again!"

"1. Very fast to respond to the the request 2. The staff was exceptionally nice, explained what they do and how they work. 3. Scheduled an appointment with a 2 hr window. 4. Repair showed up on time. (Two people) 5. They examined the problem and gave me a quote (fair and reasonable) 6. They went to work and resolved the sewer backup issue. Then they went ahead and cleared all the pipes of sludge until the water ran clear. They explained the issue was food residue buildup from the garbage disposal. That made sense since we has done a lot of summer and fall canning and used the disposal extensively. 6. They did a excellent job, very courteous and explained everything along the way. They used plastic to protect the surrounding area charged less than the estimate. 7. This is a family run business.

"Repair of small guest bathroom shower/tub area. Chose americraft bc they had no complaints on bbb and good reviews on social media. After obtaining quote greg came out to evaluate repair and answer questions. Our perception was that Greg lost interest when we didn’t want to change tub to shower or replace the bathtub. Just to keep existing tub. This would have brought quote down 2 to 3 thousand dollars. At this point Greg practically ran out of our condo. Never heard back from them. Our perception is that Americraft is not nterested if project is 10 thousand or lower. My wife may of scared him with either providing awareness of plumbing problems with common area or had all lights off except bathroom bc she’s embarrassed of our condo. Do not recommend for small projects."

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.
