"I hired Neli over a week period for 3 different appliances, my dryer, washing machine, dishwasher, and even kitchen sink! I had a fantastic experience: 1. I fixed my dryer with Thomas' excellent remote guidance, changing the timer and the switch! Fabulous guidance Thomas, with lots of money saved! I learned a lot in the process. 2. I determined that there was no dishwasher leak and in the process learned how to check for leaks and trouble shoot for some common repair issues. It cost $40.00 but as I had some water on the floor, I was ready to get a new dishwasher. Now, I am confident that it wasn't a leak and caused by putting in the dishes in a funny manner and not a repair issue. I am using the dishwasher now again with no problem. 3. I determined with Thomas' help that the washing machine had a major problem and could have spun out of control into my wall....no question, it was time to get a new washing machine! This was a well spent $40.00--I even got Thomas advice on purchasing a new washing machine and what to look for. 4. I checked the drainage on my kitchen sink and learned how to empty out the "trap" and that most likely, I am okay, but what to swap out if I have continuing issues with slow drainage. In the end, I saved lots of money, gaining and learning valuable experience! Absolutely fabulous service!"

FAQs for tankless water heater installation projects in Coxsackie, 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.
