I have a furnace blower that takes a long time to start up and sometimes
it just wont start. We replaced the motor, but still the same behavior.
I forgot to check the capacitor though. Could a bad cap cause that? Its
also quite loud when it is running.

Not sure what to do now? My next step is going to be to replace the cap
since I don't know what else it could be. ANy tips will be appreciated.

Is it a direct drive or belt driven blower motor?

Belt drive? I'd check the bearings on the blower unit. They do need
lubrication periodically.

Call a HVAC service company. You're just guessing. Lets see, you replaced
the $200 fan motor, but didn't replace the $25 capacitor. Not good.....
