Overview of XB80

The Trane XB80 is a single stage gas furnace that achieves an 80% AFUE. (80% of the fuel used is converted to heat and the remaining twenty percent is lost during the combustion process.)

The Trane XB80 features multi-port, in-shot burners, and a one-piece heat exchanger. Its dimensions are: 40" high and 28" deep.

Trane has produced at least sixteen models in the XB80 series. The (single-stage) XB80 features a four-speed blower motor and can be converted from vertical to horizontal to fit different installation requirements. Trane produces a compatible air filtration system (the CleanEffects™ system) that removes 99+ percent of allergens from the air.

Keep me warm this winter with a good furnace!

I recently bought (this last fall) a new furnace for my house. My old furnace, a Coleman brand, finally gave up on the first cold night of the fall, so I knew it was time to buy a new one before the really cold weather came. I looked at many brands and models, and decided to buy a Trane xb80 furnace, as this is the model my neighbor had, who has an identical house. The neighbor stated that he too had looked at many different furnaces, but that decided on the Trane unit based on the cost, the output of the heat, and the quietness of the furnace. I couldn't be happier with my selection, as the furnace has worked flawlessly for the past few months,even when the temperature got down to below zero for a few days. The furnace has an air cleaner that filters the air that helps keep the dust and pollen from blowing through the house. The xb80 is also very quiet, and energy efficient. My monthly gas bill is abut 15% lower than it was last year for the same period of time. I would recommend this unit to any of my friends!

Trane XB80

I added a Trane xb80 2.5 ton system to my home when I remodeled 4 1/2 years ago to cover 4 bedrooms and 2 bathrooms, while the old Carrier Weathermaker 8000 (25 years old) covers the living areas. The hvac subcontractor recommended adding the additional sytem and replacing all ductwork in addition to re-routing to create 2 zones. I have not had a bit of trouble. All I have done to the system is replace the air filter about every 10 weeks. It is in the attic (above the study where I spend a lot of time) and I have not found it to be noisy. My Carrier finally died 2 days ago and I will be replacing it with a Trane xv80. I also have not had any trouble (until now) with the Carrier in the 10+ years I've lived in this house; however, I doubt you can compare reliability of any hvac company based on products 25 years ago. Companies and products change over time. The more recent Trane has proved to be reliable, so I will stick with Trane.

Question and Answer


What direction does the air flow in a Trane XB80?

Trane XB80. When replacing filter (in unit- goes toward top of unit), there are instructions to align an arrow printed on the side of the filter with the direction of air flow. Problem is, I don't know what direction the air flows in the furnace. Does the arrow face up or down when installing the filter?

From looking at the owner's manual it seems you have an up-flow furnace (the filter(s) are beneath the furnace). If so the air goes up through the furnace. However, if for some reason this is a down-flow furnace (filter(s) at the top of the furnace) the air flows down into the furnace.

Here is a how-to on changing the filter.
