Water not draining right

[opie77]

I had a Colman furnace replaced last year with a Nor dyne unit.
I put the A-coil from the Coleman into the nor dyne. Had the system recharged. The a/c works great.

My problem seems to be that the a-coil pan isn't draining properly. I'm getting water on the front side of the furnace. When I had the coil out, I cleaned the coil and drip pan. The drip pan has no holes and the ell that attaches the tube to the pan is new.
I asked a local HVAC guy and he said I may have a slight vacuum inside the coil box that's not letting the water drain. He said to fix this I should install a p-trap. Also mentioned to watch the pipe with the a/c running to see if I can see water running out. Then shut the unit off and see if it drains then.

Does this make any sense?

Hi,

That is for above blower mounted a-coils and downflow/pull through coils found in electric furnaces.

Have you checked your drain line to ensure it is clear ?


Tape a wet/Dry Vac nozzle to end of drain line outside and pull out any obstructions.


Thanks,
