I have a Goodman high-eff furnace, 115 BTU/hr. The fan runs constantly but it has stopped blowing warm air. I'm getting 6 flashing lights as error code. What's this mean?

Remove the lower panel and look for a wiring diagram pasted to it. On that diagram there will be an error code diagnostic chart. Depending upon which model you have it could be an open overheat switch caused by a dirty filter or a bad fuse.

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

Gerge, if you go to website
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!

There is a little switch on the circuit board. Look closely at the wiring diagram and it will indicate which switch to adjust. If not, review the operating manual for details.

If the coil you have is rated at 30,000 Btu's and the condenser is rated at 36,000 Btu's; chances are it will work. However, make sure you have very good air flow thru the coil or things will freeze. If you can get the correct 36,000 Btu orifice to fit the coil, install it. Better yet, Install a 3 ton TXV (Thermal Expansion Valve).
