The "water leak" is most likely condensation from the coil, which means
he is most probably leaking combustion byproducts, ie carbon monoxide,
into the house also. You would need to tear the entire furnace down to
get to the heat exchanger coil. Some coils are fastened to the heat
exchanger with screws. There is most likely a seal you would need to
replace also.
Leave it to a competent hvac contractor as you could poison your family
with carbon monoxide if you don't do it to the letter.
