Had a call a supermarket last week, the store was too hot and no air was moving. It was on a 40 ton split system. I found the compressors iced up and triped out on low suction pressure. Went up to the air handler and found the wheel in bad shape.

damn, that's not going to be cheap
Two guys and one day to pull the roof off the air handler pull out the junk and install new. I'm not looking forward to it and of course it's been in the 80º's and really nice weather. When the new blower wheel arrives it's going to be snowing that day.
Had a job just like that beginning of September. NOT A FUN JOB but I got it done. I'm guessing you'll probably have to replace the bearings and the shaft. Does it have two blowers, or is it just the one? The one I worked on had two, but I couldn't convince the customer to replace both blowers. They just wanted the bare minimum done.
It's just got one blower wheel it's 3' wide by 2' in diameter. I bid for new shaft and bearings as well. If you going into that far might as well do it right and make everything new.
You got that right. I feel bad when I know that the customer is making a bad decision by not replacing the whole thing, because if it has to be taken out again, it will cost just as much but hey, it's not my money.
Sounds easier than the job I had to do, because it was a double whammy. Your wheel is bigger than mine were, but have fun! Disassembly is much easier than re-assembly. Are those pillow bearings?
Yep I love pillow block bearings. Just hit'em with a 10 lb sledge hammer and the carrier is off and out of your way.:grin2:Quote:

At least you don't have a 20 year old Carrier, 20-ton air handler that was enclosed by three walls!!! Only access was to the belt and control side of that unit. Had to punch out access in two other walls to install new wheel, shaft, pillow block bearings and pulleys. Count your blessings, you have it easy!
Idmth44: Yours is worse than mine was! Mine was from 1973, but I at least had access to everything!
there's something ya don't see every day...
That's just an off-set blower wheel :P
Looks like someone shot a rifled slug through it! Sure it wasn't deer season on the roof. Wouldn't have wanted to be anywhere near that when it let loose...
