Bought a house - do I need to upgrade?

Good evening everyone!

Due to a divorce, I am leaving my beloved Waterfurnace geo system behind to the ex.

I've bought a new place with a traditional furnace and A/C.

I am going to install an Ecobee (have one with my geo and LOVE it) to try and get as much efficiency out of it as possible.

Some info:

• Location - Waterloo, Ontario, Canada
• Furnace - Lennox Elite G26 (apparently 92% AFUE) - in good working order according to an inspection/test
• A/C - No idea...original to 1997 - working fine according to an inspection/test
• House - 1800 sq ft. backsplit - 3 bedroom

My main question is, if the furnace is already 92% AFUE, will I benefit from an upgrade?

I know on the A/C side of things, a newer unit will be more efficient, use less hydro etc...but then I'd have to change the furnace.

Anyway, any advice would be appreciated.
