It was a good question. I guess the next step would be to measure the blower diameter, motor hp, and furnace/A-H rating, maybe take a look at the run cap rating. What would beenthere do in this predicament?
Ok, Some people won't spring for a new furnace at the same time.
But I have never seen a furnace with a 2 ton blower. Minimum around here is 3 tons.
So I'd be safe that it has a 3 ton drive.
I have seen two in my lifetime and I'm not even in the field.
They exist (a lot of older furnaces have small blowers), so don't assume that it's 3 ton drive.
It must have to do with climate; where I am, heating is a necesessity, a/c is just a luxury which doesn't get used much.
General public's attitude towards our energy predicament:"I reject the reality of finite resource depletion and substitute it with my own; energy is infinite, we just need an alternative storage medium to run the cars on. The economy can grow indefinitely - we just need to "green" everything! Technology is energy! Peak what?"
