"Devin came to do routine maintenance on our generator. He arrived on time, and immediately introduced himself. Devin explained what was involved in the maintenance process. After that he got right to work. He didn’t maintenance, and ran the generator to make sure everything was in good order. He asked if I had and questions about what he had done or anything at all generator related. He then finished the paperwork, shook hands and left. He was friendly, courteous and professional. I would be glad to have Devin return for future service. Great job!!!"

"The master of the dishonest upsell! I have had 4 interactions with this company and the most recent left me shaking with anger. At least the first 3 times they sent someone out they were friendly and lied through their teeth. Jeff Sxxxxxx was nasty, aggressive, and unprofessional. He took everything personal and would not repair a part broken by a previous employee of auchinachie because how is that fair to me? He would not honor the warranty I was promised because apparently the previous plumber had been lying about that. He made me feel unsafe, taken advantage of and like a fool for ever trusting them. Every other interaction has been one of constantly adding money to the bill with no warning and so they were kind. When I finally asked them to honor their commitments, I was told he was there to help me but was not going to help if I had an attitude about it."

FAQs for tankless water heater installation projects in Elmira, NY
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.
