    That is normally true with resi squirrel cage blower wheels. Remove a blower from the furnace & use a ply board or something to either put static on the air discharge, or restrict the air intake. Either one will reduce amp draw as the blades will be moving less air.

    With no static resistance, years-ago they would overload & bog-down completely.
    Modern day resi blower wheels may be designed so they might not bog-down.(?)

    We should check amp draw more often, if you know the amps it should draw delivering the desired CFM, if it is drawing less duct system is too restricted or dirty blades & E-Coil, if it is drawing too much more, there may be open supply ducts, etc.

    As we see it here on the doppler, the high pressure system is moving up from the gulf........BREAKING NEWS....If you don't use air conditioning, it apparently uses less amperage. Well those are staggering numbers Brian, however if you don't use electricity at all it has been known to decrease your electric bill.
