guess I have (explitive deleted) myself
I have a ground source Water Furnace. In many ways I love it. Very economical to operate. But seems to need maintenance about once a year and that cost negates any operation savings. Oh, well.
But, that is not the problem. In my area we have only two heat/ac companies that work on Water Furnaces. One has a very bad practice of sending guys out who are not qualified to do the repair job. They will look at the unit and say "yep, it has a problem. But I have to make calls, we will send someone else later." A couple days later another guy comes and repeats the same statement. They once did this three times to me before I blew my stack. Then they sent a guy who was quailfied and did a proper repair job. Kicker is they billed me for all four service calls. This is their normal modus operandi. Crooks, pure and simple, IHMO.
The other company has been a pleasure to deal with. Well.....kinda, mostly. Their techs are very qualified and friendly. Work is excellent. Problem is they often do not send a bill for about a year and by then it is difficult to recall if the billing is accurate. Or they send a bill after a few months and follow up about a year later with more charges. Last time they did that it really ticked me off. After some discussions with them I filed a complaint with the Attorney General and learned they have multiple complaints against them for this practice.
So, I quit one company and alienated the other.
Problem is, where do I go for service next time I need it?
