Nice condensing furnace install

[mark beiser]

I guess nobody read the installation instructions to find out how simple these were to convert to horizontal.
Talk about a pain in the ass working off a ladder in an attic..
There are THREE of these things up here like this!


The ac and furnace drains used to be tied together at each unit, then all 3 tied together before running down into a bathroom to connect into a sink drain.
Over the summer, the drain clogged where it connects to the sink, so the AC condensate for 11 tons of AC backed and into one of the furnaces and leaked out of the inducer housing of one of the furnaces while they were on vacation. It caused massive cieling damage.
We separated out all the drains so each furnace and each AC coil has its own drain running by itself to a connection to the house plumbing. Still looks like crap, but there is a float switch for each drain in each unit + 3 electronic water sensors for each system now. Thats 6 total float switches and 9 total water sensors, lol.


The furnace that all the water ran out of wouldn't fire in the heating mode when I went back for a PM, turned out the control board was bad. Another one had a bad pressure switch.
It got wierd when I called our Goodman distributor and had to argue with 3 different counter people about if there was such a thing as a GMN furnace before one of them bothered to actually look it up, lol.
We don't get to many condensing furnaces down here.

Yeah, but at least I can show the customer how bad thier systems are installed and give full retail pricing for correcting the problems becaus it isn't MY company that installed the crap, lol.

NOW WHEN YOUR SAYING CONDENSING FURNACE YOU MEAN A 90% FURNACE,RIGHT? WHY DIDNT YOU JUST PUNCH A HOLE THROUGH THE SIDE OF THE HOUSE FOR DRAINAGE OR USE A CONDINSATION PUMP? OR HAVE YOU NEVER HEARD OF THOSE IN THE HILL BILLY PLACE YOU WORK FOR?

True that. True that!


Damn that's much WORSE than the verticle install my co did that one time (heat pump). It was actually EASY to work on aside from climbing onto the clothes dryer to access...

Hey bud, we didn't install these, so watch the name calling. As for punching a drain through the side of the house, these are in the attic of a 2 story house, so that wouldn't fly. I split all the drains out from eachother and terminated them all into the house plumbing above wet traps, like codes require us to here.
It would be stupid to use a condensate pump on these systems. Gravity doesn't suddenly fail at 3am on a friday night.

LMAO! Simple = good

Real nice.

Let’s build some wood return cabinets that will hold this 130 degree attic heat so we can have some homemade dehumidifiers, because we all know the humidity is probably running about 65% in that house looking at that fine example of design experience.

Mark, tell me the inside of those returns were lined with duct board.

Maybe they installed them like that so they could work on the controls while standing up. ????

The idea of standing a condensing furnace vertical in an attic is great if you have the head room. But you don't install them on a wooden box! Set them in an emergency drain pan and pull return from the side(s).

If you lay them horiontal the Em. Drain pan has to be the size of Kansas to cover the entire rig.

[mark beiser]

I wouldn't even have a problem with the wooden boxes so much if they made them the same size as the bottom of the units and just tall enough to connect the ductwork to.
But no, these freeking morons had to make the boxes 3 feet tall and plopped the furnaces down on top of the 1/2" plywood that is now sagging.
I'm waiting for one of the damn things to fall through its box so I can sell them a new one installed correctly.

They used to all have Goodman 2 speed outdoor units. 2 of the 3 died. These systems are only 11 years old, with any luck, they won't last more than a couple more years.

I did kinda shoot myself in the foot a little though. The customer was using the top end 3M filters in return grills and media filters in the Air Bear cabinets. I shouldn't have told them to quit putting filters in the filter grills, it would have accellerated the need to replace these massivly oversized, poorly installed pigs.

BTW, if you havn't ever had to clean the split condensor coil on one of those POS Goodman 2 speed outdoor units from the early/mid 90's, do a little dance of joy.

[Steve Wiggins]

Are these upflows? If so why is the burner section at the top of the furnace? I don't understand.

Oh by the way if one of them falls through the floor you won't have a chance to replace because the house will explode.
