Looking for furnace replacement suggestions

Currently have a 2006 Heil 3 ton lowboy oil furnace. I’m thinking it’s at its end of useful life as it feels like I’m constantly replacing parts and being left in the cold. I have a Bosch heat pump installed in 2021. The Heil has a single speed blower so I’d like something variable speed to make the most of the heat pump/ac. I’d also like something efficient. Does anybody have a brand/model that they’d recommend or suggest steering clear of?

TIA!
