We had our HVAC's blower motor replaced today. After the technician left, I noiced that one intake works ok, but the other intake is just not taking in air. Could this be a blower problem or the intake problem ? I called up the technician and he mentioned that there could be a problem in the duct work, since if the motor works then it is not possible for one intake working and other not working. Is this correct ?
Any help in this regard will be appreciated.
