"They’ve done a good job for us, and have been fair. Here’s our story: They fixed the motor on our furnace about a year ago. Furnace worked fine all winter. This year, however, when we turned our furnace on during the first cold evening, our furnace didn’t start. Turns out that the root cause was that a screw was no longer in place, for some strange reason. (Perhaps the screw vibrated out.) They quickly diagnosed the problem, replaced the screw, and best of all, didn’t charge! That’s really great service — taking responsibility, and giving the customer the benefit of the doubt and not charging them."
