Our furnace would not heat up the interior in temps below 40F and would otherwise take a long time to heat the TT. Ran continuously all night in cold weather.
I pulled out a 4" duct that ran under the floor and came back up in the kitchen. This duct was partially collapsed and was uninsulated in the underbelly space and sat directly on top of the cold coroplast. I replaced the 2" duct to the bedroom with 4". Insulated the duct under the floor. Also sealed up ALL the gaps/holes through the floor. There was a 10x10" hole into the underbelly right next to the furnace which would have been sucking in cold air from outside.
Now it works like a charm and heats up quickly and keeps the interior comfortably warm. The first thing I noticed is how fast the air comes blasting out the vents now. The dealer said it was the sail switch and they replaced it but did nothing to help. Pics and detail on this thread. under-performing furnace Poor design and workmanship - plain and simple...
I would look at how your ducting is run and also if there are a lot of holes through the floor. Could possibly be a cause similar to what I found. The post above also suggests blocked ducting as a potential cause.
