The repair tech experience was fine. He answered my questions, and although I was disappointed to pay $89 for him to just look at things and tell me the thing was doomed, that's the way it goes. He also said they would credit that toward the cost of a new furnace, should I get one from them. So I scheduled an appointment with their sales person. This was a young guy who did not know what he was doing (and also arrived late). He was slick, polite, and wore shoe protectors but didn't do his job very well. He told me that the intake vent was too small, and made specific suggestions on how I should cut the furnace closet door and add another vent. Had I followed his instructions, I'd have started mixing return air with combustion air and probably poisoning myself with CO. Fortunately, I knew better and got second opinions. He confirmed that he'd given me dangerously wrong information in a phone conversation the next day, after I'd done a bunch of research and sent him email asking him about it. He also said due to new city codes, they would have to move my hot water heater outside, and repipe everything. He could not cite the actual codes, and I could not find what he was talking about in the city records. They wanted to charge me $2,600 for a new gas furnace (the cheapest option possible for a 1,040-square-foot-home) plus another $2,500 for a hot water heater, moved outside. I said I couldn't afford all that, and agreed to the furnace install only. All this talking took about three hours, and they had another young, slick guy show up to give me the hot water heater quote. Both of them had to call their dads to get information, and neither really seemed to know what he was doing. They took some measurements, then left after charging $1,266.82 to my credit card, a down payment of half the price of the furnace installation. We scheduled the installation for first thing Monday morning, and I cleared my morning for it. Monday morning, I did not hear from anyone for hours, until I called the sales guy to see what was going on. He said that he did not know what was going on, and that he'd call the installer and get back to me. The installer called and told me that they could not install the furnace without also moving the hot water heater, because the whole closet would not be up to code. I pressed him for details about that, and he gave me a story that seemed like a runaround and lacked any specific facts. I think they just wanted the easiest way forward while making the most profit. I've had three other contractors since then — all of whom must comply with city codes, and all of whom must get permits and inspections for installations around new hot water heaters — tell me that this story about the need to move my heater outside is a lot of bunk. Anyway, Intelligent Design refused to do just the furnace, and after leaving me hanging all morning and only telling me this when I called them after waiting around for hours, the installer said he would refund the payment I'd made to my credit card right away. A week later, I noticed that no payment had been returned to my card, so I called their office. They said that a check would be sent out Friday (last Friday, nearly a week ago). No one ever told me that they'd keep the charge on my card and send a check to refund my money until now. So now they've kept my money, sitting on my credit card balance, for more than two weeks, and still have not returned my money for the job they refused to do. I called just now, and when I threatened to file a dispute of the charge with my credit card bank, I was told that the check just went out in today's mail. Since then I've received quotes for both the furnace and the hot water heater for more than $1,000 less each than they were asking. This seems to be the most expensive game in town, by magnitudes. If they'll even do the job. I cannot believe this company has received so many great reviews. Maybe they used to do much better, and things have turned. I don't know, but this has undermined my trust in Angie's List a bit. This is the worst service experience I've ever had around my home.
