"When I had a clogged drain, I chose Harmony to come out and snake it. I already knew the pipe was in bad shape since this is something Iâ ve had to deal with at least once a year. However, this time the issue reoccurred within just a few months. Harmony sent Adam to inspect the problem with a camera, and he clearly showed me where the line was damaged. He provided me with a detailed estimate and patiently answered all my questions, which made me feel comfortable and confident about the process. I decided to move forward with the replacement, especially since they offered 0% financing for 18 months, which made the decision even easier. Overall, the experience was truly five-star. The entire Harmony team, from the office staff to the technicians, was incredibly friendly, professional, and efficient. I couldnâ t be happier with the service I received. I recommend!"

FAQs for tankless water heater installation projects in Mckinney, TX

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.
