the same, no. close, probably. It all comes down to the contractor's supply house price, their mark up, and what their labor rate is. Ask the 2 contractors (both of them!) for an apples to apples comparison, and for a break down of the costs. Just remember typically you get what you pay for. Also ask about the different warranty each one comes with parts? labor? parts and labor?

The carrier is a huge furnace - hope you've got a large house or no insulation.

Trane XV95 is better - it has full variable speed blower (carrier has a multi-speed ecm) which delivers consistent airflow as dampers get closed, filters get dirty, etc.

Multi-speed ecm has the efficiency of a variable speed blower, but similar functionality to a regular motor.



Brand isn't important - proper sizing, installation, and setup are critical.

Ask about combustion air from outside, 2-stage t-stat, duct transitions, filter type, chimney liner if required etc.

txs so very much; have 4300 sq ft. this is the larger of the two furnaces in our home.
other info: Carrier dealer is local used to new home installs- mine is 18 years old; trane dealer is national company; I have been told that trane parts are hard to get

How large is the smaller furnace?

Are the ducts in the attic or unheated crawlspace?

Did the contractor do a load calc on the space heated by the the furnace to be replaced?

What size is the existing furnace?

If the existing furnace is mid efficiency, you can replace it with a 80k high eff unit and get the basically same output.

100k x 80% = 80k output

80k x 95% = 76k output


You won't miss the 4k btus - it's probably oversized if the house is properly insulated.

Your ductwork was probably never sized for a larger furnace than what's there, so purchasing a 100k unit is not a good option.

100k input high efficiency replaces a 115-120k input mid efficiency.
