"I thought listening to recommendations on Angi would be the right way to go, man was I wrong. I called them about a water leak at a cutoff valve and when they arrived late, they charged me over $400 to replace the cutoff valve. Then gave me an estimate to replace water lines through the attic instead of having them under the slab as they are now, If water leaks in the attic would not you think that would make a worse mess and damage? But the kicker is they gave me an estimate of over $9,000 to do this which one person to do the work and would take one day? $9,000? Were the new water lines going to be made from gold or what? Never again will I call them."

Tankless water heater installations FAQs

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.
