"They claimed it was a week long job, but then came in and did the work in one day. I paid over $400/hr for the work they did. They claimed to do the work with the proper permits, but they didn.t I was left holding the bag, trying to get the work permitted after they did the work. The work has been sitting there for about a month as I try to get the work inspected and get this nightmare behind me. I am so naive and trusting. Never again. I would never recommend William Parish Plumbing, quite the contrary"

FAQs for tankless water heater installation projects in Cary, NC

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.
