We thought we had a 'fixable' issue with our 2 year old furnace. Turns out we were dead wrong. After two attempts and a lot of 'B.S.' technical jargon (resulting in a $139.95 'service' fee & including a water heater service we never even requested)...turned out they still could not identify exactly the solution to the problem. Incidentally, I did present their own company coupon for $30 off 'ANY SERVICE'--which was promptly denied, because that only included services on major installations like 'pumps' (example they gave me, not one I made up). Approx. 3 hours after they left, my furnace began leaking water from the back--dripping at a rate of 3-4 drops a second--all over the basement floor. When we called, their primary focus was the service fee call for them to come out again, $95--which would only be waived if it could be determined that the malfunction was something they did. After much calling back and forth, they declined to come out, informing me that such leakage was 'normal' after such a service. I would have to wait over night and call them again in the morning to report if there was no change. Thankfully, I have no carpeting or flooring around the unit--if this leakage was so 'normal' why did they not explain that to me before they left?? One totally 'unhappy' customer. Do not ever use them for your boiler/furnace problems, unless you like being given the run-around & being ripped-offed.
