Today I noticed that there is very little air flow coming from my vents in my house (almost none at all). I have a very old furnace (30+ years), yes I know it's old! We plan on replacing it by the fall. I can't live without my AC this summer!
I just checked the blower & blower motor - they both appear to be working. I pulled out the blower unit and it spins and does push air. The motor appears to be working as well. The motor runs 100% of the time at a slow speed, and when the furnace comes on, either for the AC or Heating, the motor spins up. Even when the motor spins up to a higher speed there is no air coming out of the vents. I took off a plastic plug that is in one of the large air ducts coming off the furnace about 2ft away, I could feel a slight breeze inside but it wasn't super strong. I took off a little vent on the side of the furnace and looked inside, It doesn't appear anything is plugged.
Any idea what could be the * Could it be the motor * How do I *
Thanks in advance for the help.
