Condensation leaking into furnace and DIY furnace evap replacement
Posted 24 October 2012 - 11:27 AM
This unit is old and I am guessing it needs to be replaced. the outside unit was replaced 8 or 9 years ago with a Goodman unit off of my homeshield warranty. I need to replace the blower motor as it is overheating and cuts off, slightly smoking after about 13 minutes. Just pulled the blower housing and about to pull the motor and source a replacement. I don't think the interior leaking had anything to do with the motor going out, as it was dirty, but dry.
I am thinking of a DIY replacement over a nice Texas fall weekend in November. How hard can this be? Mechanically it has to be easier than the cylinder head job I just did on my kid's Taurus. Seems like if I 1) match coil to compressor 2) have tech come and recharge freon and check pressures 3) am careful to make sure the installation is clean; it should not be too difficult. I am thinking I need a tech evacuate the freon before removing the old unit and then come out again to charge up the installed unit. Unless there is a way to collect the freon in the compressor? (read something about that somewhere)
Anyhow most important right now is clearing up the condensation leak since I am replacing the motor later today. But I am interested in opinions on DIY install as well.
As always thanks in Advance for any input!

As for replacing the coil, if you're going to have a tech come out twice and do all that why not just give him the replacement gig too. Won't be that much more.

make sure to plug any stand pipes at the indoor coil with tape or a rag before using the compressed air
this will do nothing for dirt on the coil itself but will get the water flowing and stop any further damage to the heater

COULD a dirty evaporator coil cause excessive condensation during humid times?

if you have an "a" coil the drain is only connected to one side of it , the other side has a drain line or some other way to get the water over to the side with the drain tube
this can be your problem
you also may have a crack in your plastic drain pan or a rust hole in a metal one
