"5 stars for the final product, 3 stars on the customer service experience. I contacted Akraba fully aware of their minimum but had a number of tasks and wanted to have the work done by professionals rather than trying to DIY it. This included replacing a window that would not open, replacing an interior double door with one that would lock, repairing the cosmetic damage around a skylight, and replacing a ceiling fan. Louie and Ily reached out immediately, listed to our concerns, requests, and HOA requirements and were able to not only provide a quote for the needed work but also quoted out replacing our fence at a more than reasonable price. While we did have some minor issues with the workers they sent (primarily regarding scheduling), Louie was very reassuring throughout the process and personally came to review and address each concern. Now that the work is complete both we and the HOA are happy with the work they did would recommend them to anyone that needs large projects done."

FAQs for tankless water heater installation projects in Sunnyvale, 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.
