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.

"Excellent work - on time and professional and even took time out to reprogram the thermostats"

Total Plumbing offers a variety of plumbing services to meet your needs. Our family owned business guarantees your satisfaction. Services offered include, but are not limited to, hot water heater installation and repair, water softener installation, plumbing leak repairs, and new appliances and fixture installation. Contact us by phone, text, email, or the Angi app to schedule an appointment to service your plumbing needs.

"⭐️⭐️⭐️⭐️⭐️ 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!"

FAQs for tankless water heater installation projects in Walden, NY

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
