There is a new model in the Trane Furnace lineup.  Better yet, this high efficiency furnace achieves a 95% AFUE rating, and is eligible for rebates.

This new single stage replaces the XR90.

You can find specifics on the new model HERE.

As of December 31, 09, the manufacturing and sales of mid efficiency furnaces will be no more in Canada.  One wonders when the U.S. will follow.

And will prices will drop on high efficiency?

However, this phase out may be a matter of concern to some home owners.  Especially those living in older homes.  There are code regulations for where, and how, a high efficiency furnace can be installed, so replacing an older furnace as of January 1, 2010 may be a costly nightmare.   Not only that, many older homes have undersized duct work, and these furnaces need the capacity for airflow.

So, heads up Canadians!  Do your due diligence now.  Maybe you need to buy a mid efficiany furnace while you still have the chance.
