"It was an excellent experience! My old Kenmore fridge (probably from the 90s) quit cooling/defrosting. After looking to replace it and finding thanks to the pandemic refrigerators are on backorder for months, I called 3 appliance repair companies who didn't call me back. I found Neli and was able to set up an appointment at a time I picked.. An incredibly patient tech (Chris C.) came chat on at the appointed time. I waited about 5 mins as he was wrapping up another call. I walked me through the diagnosis using a virtual support app on my phone. He was able to help me with taking things apart, helped me use our multimeter, and diagnosed the problem. I can do this repair myself. He gave me the exact part numbers and told me what I need to do. All for $35 for an hour on a Sunday. I can't believe how great this was. I thought I had to replace my refrigerator, but for $35 + $111 in parts (I could have gone cheaper but chose OEM) my refrigerator will return to health. Their website lists the tools you will need for a diagnosis/repair, make sure you have them ready. For refrigerators, you need a screwdriver (flat & phillips), a socket set, a multimeter, and theoretically a pair of pliers but I didn't use them. Also make sure your phone is charged (lesson learned)."

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.
