Need quick answer on furnace question

15 years ago

I have a price I'm going with on my 2nd floor system for an 80% Trane variable speed 2 stage furnace (XV80) (coupled with a heatpump).

The contractor just called me and said he has a Trane XV90 he would give me for the same price (tuy060r9v3w). Looks to me like this is a older model but is a 93% variable speed 2 stage furnace. I think it's one they have in stock and would like to get rid of.

It's a "condensing" furnace which will be installed in the attic. There are already drain lines from there to my crawl space. I live in NC.

Is this a good offer?

what size is upstairs living space?

what size is the XV90? this is important.

what brand/size/mdl HP?

normally you don't place condensing furnaces in attics because of freezing issues. however, I wouldn't expect that to be an issue for a NC location.

About 1300 sq ft.

TUY060R9V3W: 37,000 - 56,000 output BTUh. I believe this is the correct size.

2.5 Ton Trane XR15 HP

sorry. I did not read your post close enough about the size of the XV90.

probably a toss-up. however you would probably never use the second stage of either furnace.

the XV90 is an upflow mdl. Don't you really need a downflow for attic location? might be something to ask dealer.

have no data to back it up but I would bet the XV80 would have lower operating costs just because of the 1st stg sizing BTUs.

what stat are you getting? it needs to be a two stg with dual fuel capability and outdoor sensor.

The XV90 can be configured for upflow, downflow or horizontal air flow, depending on where you need to install it in your house. Getting Honeywell IAQ stats.

not trying to be disagreeable.

I have the XV90 in an upflow mdl. Trane offered the XV90 in both upflow and downflow mdls-same in the XV95 and XV80. Must be reason for this.

It will be installed horizontally. Does this make a difference?
