"Called them on recommendation from Angi's list to diagnose and repair tiny (4 inch little puddle) water leak in front yard. Plumber said he shut off the water but still saw a bit of flow. Said only solution was to put in an entirely new main water line in a different area. Dug up out front yard, put in new line. Problem didn't go away. Came out 3 more times, each time puzzled why they had not solved the issue. On final call, he dug up some rocks (we are in Arizona) and found a small capillary tube from the irrigation system was cut and leaking. Turns out that was the cause of the puddle. None of the rest of the work was necessary, a complete mis-diagnosis. When plumber said he still read water running after it had been turned off, he made a mistake. There never was any other leak, rest of yard was bone dry (again, Arizona). Only issue was the irrigation line, he put a simple little rubber plug in irrigation line, problem went away! A mistake was made, owner won't own up to the mistake. I paid in full believing what they were telling me...until the problem was not solved. I tried to work out an amicable refund with the owner. He promised a call back after trying to get a return call for a week. Now refuses to call me."

Established in 1939, we do residential HVAC and plumbing the right way, not the easy way. At Goettl, we are total home comfort solution providers, enhancing the quality of life in the communities we serve. As Sadie Certified professionals, equipped with cutting-edge tools and technology, we deliver a superior customer experience, one home at a time.

"We purchased a new AC and a new water heater through Goettl within the past 5 years. Their techs are friendly, but management is horrible and WOW are they insanely overpriced for the quality of work. They placed the AC unit in a position where it is impossible to change the filter unless I take the door to the closet off. They replaced my hose bib, which two weeks later began leaking (which they admitted was their mistake). They came out to find the leak and in doing so had to cut into my inside wall. They had a restoration company come out to look at the wall (which was supposed to be fixed on THEIR dime for THEIR mistake) and neither management through Goettl nor the restoration company ever called me back - for over 3 months of trying to get in touch with someone to come fix the wall!!! My wall is still not fixed and I have realized I must do it myself if I want it to be done. Not to mention, I was scammed into signing up for their $20/mo service last March. They now want $120 to c"

FAQs for tankless water heater installation projects in Green Valley, AZ

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.
