Trane

Trane is a sibling business of American Standard and is owned by Trane Technologies. Trane gas and oil furnaces are engineered specifically for efficiency and temperature control. There's an ideal furnace for every house with one-stage, two-stage, and modulating furnaces. Trane furnaces are dependable, quiet, and guaranteed to keep you warm and comfortable even on the coldest days of the year.

It has two gas furnaces and two oil furnaces that provide consistent heat throughout the winter. The variable-speed fan of the XV80 oil furnace adjusts speed to give a steady flow of warm, comforting air. The Trane CleanEffects Air Cleaner, which is incorporated into the XP80, removes dust, pollen, and other irritants from the air. Both oil furnaces have an AFUE rating of 85 percent, which is excellent for oil furnaces.
