Trane 90 furnace series reliability and comfort

[4388]

I have another question now regarding the reliability of Trane XV90 series - and also is there a real comfort/efficiency difference between XV90 and XL90?
As a matter of fact - is there a significant difference between 2-stage and sibgle stage heating? For us anything will be an improvement compared to our 30-year old furnace, but how much is enough?

2-stage variable XV is mych better then the single stage alot more comfort and energy savings with the variable speed blower DC

The 2 stage system will give you greater winter comfort. If used on a 2 stage stat, you'll get long run periods on a very quiet low fire/low blower. You are lots more comfy with a gentle heat than contantly going between full blast and off, like with a single stage furnace.

The variable speed blower of the XV offers better control of the amount of air being moved as duct & filter conditions change. It can be set to increase dehumdification in summer cooling season. Also it has a very low contant fan setting for moving air when not heating or cooling. This setting uses a fraction of the juice of a standard blower.

The XL90 is an expensive 2 stage furnace, there are many for less money. I guess I'd skip that furnace and either spend the extra for the XV90 or just stay single stage.

I have the XV90 in my home, and had it for 2 years. been happy with the comfort it provides. Neighbor house behind me has same floor plan as mine, and he got rooms that are cooler, and is planning on getting on before winter.

Get a two stage t-stat on ANY t-stage furnace.

I think in the long run you will be happier with the XV90.

Also i'd suggest getting the 10 years parts/labor warranity on ANY variable speed system in the market.
