First my sewer, now my furnace (Anyone know a furnace guy that has reasonable rates & quality work)

If you don't find someone let me know, I work in the commercial/industrial HVAC and I can find someone who does good prices. Glad to see some other people on here in the trade.

Ain't that the truth

Get a 96 % if you can vs a 80 %. The price difference will be paid in less than a year.... did it in 2 houses and i stand by my judgement.

I used marxair, and full replacement was less than 4k for a goodman.

I have to wonder if the difference would be noticed in a Drafty poorly insulated house built in 1942 but it of course is worth checking into.

80% furnaces are going to vent 20 cents for every dollar of gas burnt. 96% furnaces are going to vent 4 cents for every dollar of gas burnt. he save money but it depends on how many dollars of gas you burn a month to keep your house warm. If your home requires $100 to heat, your going to save about $16 a month. For my company I end up charging about $1400 extra for a 96% due to the increase in equipment cost, additional material and increased labor. They are more cost effective to put in during construction of a house then during a retro fit.

I would tend to agree with the 96% suggestion. At one point a fee years ago there was talk about banning the sale of 80%ers in the northern states. The only way I wouldn't do a high efficiency is it the vent was not possible to run or you get an 80% for dirt cheap. Ie: got my Trane 80,000 BTU 2 stage 4ton drive for 200$ just has a dent in the door from a hand cart.

My current furnace vents up a pipe within the original chimney to the roof. can you vent the high efficiency furnaces in such a manner or do they need vented horizontally out out of the basement to an exterior wall?

The 90% furnace needs to be vented with PVC out the side of the house.

The 80% can be vented into the "chimney" as long as it has a flue liner in there. Does your current furnace have a standing pilot? If so its probably vented into a masonry chimney with no flue liner. The chimney will need to have a flue liner ran down to be compliant. Sometimes the chimney is already lined and you don't need to do it. Sometimes the "chimney" is nothing more that a double wall flue pipe going up to the roof.

If its a masonry chimney, go outside and look to see if you have a metal pipe coming out the top of the masonry. If it does its already "lined" and you can vent a 80% furnace in it.

I don't want to high jack this thread, but what happens if your furnace is not in an area that allows venting out the side of the house and you want to upgrade to a 96%?

I had a pipe shoved down it when I had the water heater replaced.
