I think that I've finally narrowed my proposals down to these 2.
Lennox 97% modulating gas furnace, 66,000 btu- model SLPUH070V36B
Lennox XP 17 3.0 ton heat pump
Lennox evap coil, model cx34
lennox touch screen iaq programmable thermostat
air plenum with Merv 16 filter with uv light set up
Carrier infinity furnace model 58mvc060f114 3 stage variable speed furnace
carrier performace 16 ser dual stage condensor, model 25HPA636
carrier evap coil CNPVP3617ATA
Infinity thermostat control
infinity air purifiier
honeywell large bypass advanced humidifiers
I did have a manual J and an energy audit performed. FYI, the Carrier proposal is $8,000 more. I know by looking at the specs that the Lennox heatpump is only a 1 stage, whereas the carrier is 2 stage.
