This company will rip you off in the most shameless way. To stop two simple valves from leaking? This job can be done by an inexperienced home owners in 30 min. With Lanz, you have a choice between their "plain" service with 90 days warranty for $368, or "platinum" service for more than $600. There are "gold" and "silver" in-between. Much more expensive than my doctor (without insurance) or my lawyer. When you call, you talk to a receptionist, explain your problem, she does not listen because she does not know a thing about plumbing. At this point she transfers you to another receptionist, who pretends to know something about plumbing, and you repeat your story. Then the technician comes, totally unprepared, charge you $69 for listening to you and leaves till next visit. Shop around and avoid these guys!
