Is this for heat or cooling? If it's heat you can lower the speed. If it's cool it needs to be ran on certain speeds according to your location, out door unit size, etc. If it's a new blower wheel it may be a lot cleaner then your old one which would make it move a lot more air. Your ducting could also be undersized which will cause inefficient system operation and high velocity air from the registers
It is for cooling and indoor unit. Blows cool just not adedquate enough air flow. Almost as if it was like someone blowing on you. Do you think there may be a something wrong with ductwork. This is an old unit at least 10 yrs or more? At first we head something rattling, the blower fan was making a lot of noise and found something like a piece of metal that fell down on blower wheel. Very strange.
I meant to say it is hardly blowing. Prior to working on it there was a hard banging noise and again hardly any air blowing. I was told last year during cleaning that I would eventually need a new motor and blower wheel.
When work began the motor would start the wheel then stop and I spoke to a AC man here where I work and he said as long as the motor was working I most likely needed a capicitor, replaced that, then seemed fine air worked cooled off house, set thermostat to 70 but next day it seemed the system just ran and ran and ran temp in house went up to 76.
My next step is to look at coil and clean that off and then if that doesn't work I guess I need to check ducts? I don't know how I am going to do that?
