I'm usually very handy diagnosing problems around the house, and have learned how my furnace works (intimately, from previous problems!) and made repairs myself. Over the winter, though, nothing I could figure would make the furnace quit working, and it was cold! So I gave in and called Neal Harris, because they were local to the Waldo neighborhood. I am generally very skeptical and not so very trusting of repair persons. However, the problem turned out to be the motherboard of the furnace (little wonder I didn't figure that out). I was right beside him as he diagnosed the problem, there was no hinky business going on to rip me off, and sure enough when he said the cost (which seemed really high to me) was really reasonable, I did some checking from online and calling parts stores, and in fact he could have charged an extra hundred bucks and still been competitive. No gouging, and when the part was in they were out the next day to install it. Also, the repair persons are obviously supposed to try to up-sell a service contract (very expensive, really) for preventative maintenance and discounts on repairs, etc., which I would never buy, but there was no hard push about it, he basically filled in the amounts on the documents, of what it would cover, and just said I could look at it later, and if I was interested to call. I appreciated that.
