I have lived in my house for almost 4 yrs, no issues with furnace to date. Trying to be a good Preventative Maintenance kind of guy, I scheduled a $60 tune up through Angie's List. A service tech came, 30 minutes late for the 2hr appt. window (so 2.5 hours after window started). He did call ahead of time to let me know he would be late and I appreciated that. He proceeded to do some air flow, gas pressure, and temperature testing as well as change all the return filters in my house. He was a very polite and professional guy. He concluded that my furnace worked great, I paid my $60, and he left. Three days later, the furnace started acting weird. It would shut off after about 15 minutes of heating. If the house only needed to be heated 1 or 2 degrees, this didn't matter, but if I needed the furnace to run for a longer period I was out of luck. I called back for a follow up appt. A few days later, a different service tech showed up, 15 mins early to the appt. window. This technician was much older, seemed to be quite a bit more knowledgeable, but was very unprofessional. He kept cussing at my furnace and telling me "why he would never buy a Lennox" for his house and that the "freakin' Engineers" at Lennox didn't know what they were doing. I happen to be an Engineer (albeit not for an HVAC company) and didn't appreciate this. He troubleshooted the condensate line, found no issues, and then narrowed it down to the gas valve. It wouldn't hold a very steady flame on low-fire mode, and would completely lose flame on high-fire. He cycle between low/high-fire modes many times using a jumper wire, which is probably standard practice, but seemed that it would be a bit harsh on the blower motor. He concluded that I needed a new gas valve and could have it in a few days. The office called me the next day and we scheduled an appt. for a week out. During the period before the next appt., my house understandably got very cold, and I decided to run the furnace just to gain a few degrees. I turned it on, continued doing whatever I was doing at the time, then had a smoke alarm in my house start beeping and saw some smoke coming from the main air return. I realized that the blower never kicked on, which must have caused the coil to get very hot. During the next appt., the same technician spent most of his time troubleshooting the blower. Same type of attitude towards my "@#$% Lennox". He concluded that the motor was fine, but the speed controller needed replacement. Painful news knowing that my furnace was working fine before my very first appt... The technician did advise me to buy a unit online, as Bailey's would likely charge me for a new controller and motor (they come as a package from Lennox) and it would be very expensive. I appreciated his honesty on that. I assumed that Bailey's would install the new controller for me, but I couldn't talk the main office into charging me less than 1hr of labor to install. It's literally two small bolts and an electrical harness connection, 2 minutes at most. I decided to do that part myself and save $120. So, at the 4th appt. and after 4 weeks of no heat in December, the technician replaced my gas valve and my furnace roared to life again. I'm now happy that it's over. Bailey's seems like a good company with good customer service. The first technician was either very inexperienced and damaged something on my furnace, or it was just a terrible coincidence. The second technician was rough around the edges but knowledgeable. I can't help but think that he may have damaged my blower controller, though. Or I'm just super unlucky.
