    Not cooling from squirrel cage blower
    Hi... my central air system does not seems to work. We cannot received any cool air at all! We have done everything. Please note the following:

    - we removed heat exchanger and cleaned thoroughly with special chemical which removed a lot of grease and dirt
    - the cold water going in the coil is cold enough
    - there is no temperature difference between the inlet and outlet line for the coil
    Water
    - neither inlet nor the outlet ducting is damaged
    - return is designed with the roof space that should act as a vacuum
    - cannot feel much air when hand is placed against the diffuser (inlet vents)
    Inside building
    - when door near to squirrel cage motor is opened an increase in airflowed is
    Noted in building
    - motor seems to spin at proper freqeuncy

    I would love some help and suggestions.

    Thanks!

    That makes me think you have a problem with the intake, maybe it's blocked or a dirty filter? Hang tight an expert should be along shortly. Good luck

    You have a cold water air conditioner in your house or is this a commercial building ? Cooling tower? Air flow may increase when front cover is removed, but only slightly. Please describe your system.
