"Mike installed a new underground gas line for our inground pool heater. He did and amazing job! He was so fast and hardworking but also personable and prefessional. He answered all of my questions in an easy-to-understand way for someone who isn't in the industry. I felt I could trust him and didn't feel I was being overcharged or taken advantage of. Will definitely be calling Mike again for any of our future needs. 10/10!"

"Great work. Pavel and crew showed up as scheduled and did an excellent job installing the new appliance which required modifications to the cabinet above and then ran the exhaust pipe through the attic to the outside. I have used them in the past and would highly recommend 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.
