I have a Bryant Plus 90 central air/heating unit. I am getting leaking water from under the inside unit and cannot figure out where the water is coming from. Can anyone help fix this problem or let me know if I need to call a professional. Also I cannot find where the air filter is to change it. Please help as I am not very handy.

It's condensation on the evaporator coil. There is a drain that is most likely plugged. Probably not a serious issue, but if you aren't handy a service call will fix it and find your filter for you.

Is this something that can be fixed easy? If so can you tell me how to do it? I still have water getting on my floor in the laundry room and if I can fix it with out calling a professional that would help

Is there a drain hose somewhere on your furnace... possibly going to a floor drain? If so, it connects to a drip pan somewhere in the evaporator compartment. Turn off the power so the blower won't come on and look for the drip pan or tray under the coil. Check for the tube and see if the outlet is plugged.
