    Loud what? Banging sound? When did it happen? As soon as the thermostat called for heat, or when the fan began blowing the air?

    The loud noise is when the fan starts to blow and the filters seem to get sucked in.

    you have a restriction in the duct. The noise is the oil canning I described. If your using high capacity filter and they are installed in the rooms rather next to the furnace they are to restrictive or plugged with dust. Remove them and see if there

    Yea, as usual I agree with Woodbridge. Let me tell you this though, just the simple fact that it is a Goodman furnace should have you concerned. If it is a air restriction this makes the heat exchanger more prone to fail as he said but in the ten year

    CR, guess you missed her reply. The contractor replaced the motor. My guess it was the frame that cracked that supports it.

    I have a Goodman furnace and AC. After the AC is on for 1-2 hours the furnace starts making a loud noise and the AC is not working well. The furnace seems to freeze up and there is water evident at the bottom of the furnace?
  • Woodbridge Environmental
    You are low on refrigerant in the ac system. When that happens the coil above the furnace gets so cold instead of cooling the air and removing moisture it freezes the moisture causing the water to turn to a block of ice. IN turn this stops the air from
