Hi,
If you want to go 2 inch through the wall you can do that, but go with three inch from the furnace through the ell's and then reduce it down at the end, then you will be okay,,,,,2 inch all the way will probably give you nusiance trips of the pressure switch...

Goodman Model GMV950905DX-an electrical surge burned out the transformer which I replaced, also replaced the circuit board. The variable speed furnace will no longer kick into high speed and it will l


If I remember correctly, there are dip switches on that control board that can be set individually. It is possible that it is just a setup issue. The switch positions should be explained in the installation instructions. I know that some Goodman and Amana two stage furnaces can be controlled by a single stage thermostat, but the dip switches have to be set properly. If the switches are set correctly the furnace will run in low stage heat for approximately 5 minutes and if the thermostat hasn't satisfied yet, it will kick in to high stage heat. I hope this points you in the right direction!

Why does furnace heat cut back?


You might try checking your return filter. The new filters (pleated 3 month, ie real expensive ones) cut back your air flow 35% from the amount the regular 30 throw away allow. When air flow reduces the temperatur from furnace increases and can cause inadvertant high temperature limits to trip. If you are using a clean return filter, next you need to physically observe the air inlet side of your cooling coil to see if it is blocking air flow due to being dirty. If you have trouble with seeing the inlet, you might need to get a professional to take the air handler apart.

I'm considering installing a Goodman LP Gas Furnace:sizing? Ops?


Gerge, if you go to website www.energycodes.gov
you can do a heat load calc yourself. Basically, you figure out the sizes of walls, total area of glass. total doors to outside, ceiling area and types of building materials used. It is pretty easy and then you will know for sure. The contractor should be suppling you with one but if not use this, it is free!
