Had a local HVAC company check out our furnace a few days ago -- first time in almost 8 years ("if it ain't broke, don't fix it," and we have carbon monoxide detectors). The only thing he could find wrong was that the run capacitor's capacitance was down somewhat: 3.6uF instead of 5uF. I asked how much a replacement was: "$80 if it comes off the truck, but if you go to our office you can probably get one for less." Since I had replaced a dual capacitor on the AC for only about $20 a couple years back, I declined to have the capacitor replaced. I now have a new one I bought online for $6 + $3 shipping.
