"I was requesting an estimate to replace my main line from water meter to the house. They sent a tech out to do the estimate. The tech did not do any diagnostic work to figure out if I needed a new line or not. He measured the line length and said he'd give it to the office and have them send me a quote. He then charged me $94.30, That's $67.50 for a half hour of work, and $24.05 for miscellaneous supplies. On top of all that was a $2.75 charge for using a credit card, I wasn't given any other options to pay. What misc supplies are needed for a quote? Now over 2 weeks later I still haven't even received the quote I request, and was charged for. They definitely haven't done anything to win my business. I feel taken advatage of. Who charges for quotes?"

FAQs for tankless water heater installation projects in Alva, FL

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.
