Hi my furnace is blowing cold air after I had a heating tech replace the inducer. My furnace was making a lot of noise when it would start and shut off and they came and looked at it and took the inducer apart and the wheel was breaking in the middle so they ordered a whole new inducer motor kit and put it in and now my furnace will only blow cold air. I was working just fine until they put the inducer kit in and now it will not heat my house. It will run without shuting off and I let it run for almost three hours the other day and it only heated the house two degrees. I looked at the burners and they are all lit and the blower is working but I'm not getting warm air. Thank you for your help. I have a natural gas furnace it is a Payne 350mav036080

It should be under a warranty, call them back.

I did and now they think it's my gas valve. I don't see how it can be my gas valve. It was working just fine and then they replaced the inducer motor and now it blows cold air. If it was my gas valve the burners would not light and stay lite would they.

No it doesn't sound like a gas valve to me either, but it is hard to guess what it could be.
