trane xv95 4 ton blower?

I am looking at replacing my 15 year old carrier system with a high efficiency variable speed unit.

I really like the trane xv95 but I just got an alternative quote from a Lennox guy who really seems to know what he is talking about. He measured the house and duct sizes and concluded that I need a unit with at least a 3.5 ton blower, preferably 4. He recommends the Lennox sl280v (uh090v48b).

My current carrier system has a blower indicator of 14 which he said equals to 1400/400=3.5 ton.

Lennox do not do a high efficiency 3.5 or 4 ton blower model so the best he could sell me is an 80% efficiency unit.

How can I determine what the blower size is of the trane xv95 unit?

This link below has some specs on the trane xv95 but I do not know how that compares to 3.5 ton blower capacity.

Welcome to the forums.

I'm not really sure what you're asking.

Trane xv95 is a generic trade name. There are many different XV95 model numbers based on features and size.

I guess my question is, is there a trane xv95 model that has a 3.5 or 4K blower motor.

Or how can I determine whether a unit has a 3.5 or 4K blower motor.

I'm still not following you..... 3.5 or 4K what ... blower motor ?

You're purchasing a complete system based on required size and load. The blower is sized based on cooling tons.

Do you have or want a/c?

The blower just needs to be able to move enough air to allow the furnace to run properly and not overheat, and the furnace should be sized so that it can maintain the setpoint on the coldest night of the year.

Now, if a/c is in the equation, it might be necessary to oversize the furnace to get sufficient airflow for cooling if you're in a mild climate.

The guy pushing lennox quoted a 90 000 BTU (a little lower in reality) furnace, which is on the large side. What size is the existing furnace? Where are you located? Is the house large (size?) or poorly insulated?

Lennox do not do a high efficiency 3.5 or 4 ton blower model so the best he could sell me is an 80% efficiency unit.
That's a lie - you should be able to get a 4 ton blower in any 80000*+ btu furnace. (some manufacturers offer a 4 ton drive starting at 70000 BTUs - goodman/amana comes to mind)

*At 70-80k, the manufacturer offers two versions - 3 ton drive or 4 ton drive.
