Jones Services is now a NO CONTACT service company. Our plumbers, electricians and HVAC technicians are running NO CONTACT service calls. We literally stand in different rooms than our customers, emailing or reading out loud our findings. No handshakes, no paperwork, not even allowing customers to touch iPads. Our technicians wear disinfected gloves, use disinfected tools and whip down anything their gloves and tools touch after servicing equipment. We practice NO CONTACT at work now too. Technicians are not allowed in the office, equipment and parts are delivered to their trucks in the parking lot. Only one employee per vehicle. All company meetings are conducted via Zoom. Most office personal are working from home. Those in the office work apart from each other. No one wants to be quarantined with their toilets backing up, without water or electricity or heat or hot water and now without air conditioning or air filtration or air purification. We are doing everything we can to help all our employees stay health to protect ourselves and our customers.

"Any plumbing/heating issues I always use Jones. Although the price is a bit steep, the professionalism that I receive makes it worth every dime spent. I had no hot water & the next day I was able to get the work done. Any tech I have encountered has always been nothing less than a great! I had the pleasure of meeting initially meeting Mike, Matthew was the one that did the job. He was punctual & very professional from start to finish. Prior to starting the job, he confirmed the exact work he would be doing. Once the job was completed he took the time to do a walk-through, to which he was very thorough with providing an explanation of everything & patient with all my questions. Which didn’t make me feel like it was a rushed job & he more importantly didn’t leave any mess. It is always a pleasure doing business with them! They always meet my expectations."

"We have a smaller upstairs bathroom that had not been touched since 1975. The shower had been unusable for over a decade due to leakage. The space had to be completely gutted down to the studs and completely redone. The contractor we had used several times over the years retired, so we needed someone new who we could trust. Radical Renovations (Angelo) was recommended to us by N & S Supply in Kingston and I'm SO happy we hired him! He's professional, responsive, patient and finds solutions to all issues that invariably come up when you're dealing with old homes. Plus, the crew who he brought in to work with him was also pleasant and professional. I would absolutely hire Angelo again...in fact I already am!"

"⭐️⭐️⭐️⭐️⭐️ Kevin at Total Plumbing is the absolute best! Our Navien combo system was acting up, and another company (T Webber) told us it needed to be replaced entirely—for $7,000—even though it was still under warranty and this fee was just for their labor! Thankfully, we called Kevin for a second opinion, and we’re so glad we did! Kevin quickly identified the real issue and assured us the unit didn’t need to be replaced, just repaired with a few new parts. He fixed everything for a fraction of the cost and saved us thousands of dollars. His honesty, expertise, and professionalism are unmatched. Thank you for being so reliable and trustworthy, Kevin! Highly recommend Total Plumbing to anyone in need of an honest and skilled plumber!"

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.
