JBL Home Improvements, Inc, located in St. James, is a family owned and operated remodeling business specializing in residential projects. Owner & Contractor David Kaplan, General Manager Jill Kaplan, along with their team of talented professionals, are dedicated to providing outstanding workmanship and customer service to homeowners who live in their community.

"The project ran smoothly, on time, and on budget. Dave and his team were professional, clarified issues before they became problems, and left no loose ends. The project involved the demolition of existing built-in cabinets and a massive, green-tiled shower that was designed with one purpose in mind - growing mold. We increased the footprint of the 10x11 sq ft room by reclaiming space from an adjacent oversized walk-in closet, which made a perfect alcove for a new free-standing tub. The tile installation was done to perfection, and the installation of all components, including the neo-angle door was completed without issue. To their credit, the team helped us isolate a crack in the new Kohler toilet and installed the replacement part without complaint. We're looking forward to working with JBL on our next project."

FAQs for tankless water heater installation projects in Centerport, 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.
