These are comparable systems. I assume the Carrier furnace model is the 58CVA 70 KBTU model. It will require the Infinity controller, no substitute. Wifi Mdl available if interested. On the Trane, nice system as well. I assume the 80 or 60 KBTU XV80 furnace. It will require a true two stage thermostat, either the Trane XL900 or HW VP IAQ stat Mdl 9421. WiFi Mdl available if interested. On Trane condenser, you might check the XR17 AC model. What about filter media cabinets? You will need one. Both systems only best matching brand evap coils. No third party coils allowed. I wouldn't have a problem with either system. I probably would let price, dealer reputation, and your comfort with the dealer be my guide. I prefer authorized Carrier and Trane dealers. IMO

What exactly are you looking for in a system? What is your budget? You must use the the larger air handler to get the best performance/efficiency numbers. The Bryant 280 is the equivalent to Carrier's GreenSpeed Pump. It will be pricey and for your location, I don't think it's worth it. I still like the Performance configuration I listed in my earlier post. Regarding heat strips. Each KW heat strip yields 3420 BTUs. I would not have 15 KW unless it was staged in 5 KW increments. Electric service should be checked for capacity. I like the HP condenser, air handler, and heat strips to be on separate circuits. Here is a look at various Bryant Evolution model configurations with the Evolution 006 air handler. 5158824 Active Systems EVOLUTION EXTREME PURON HP BRYANT HEATING AND COOLING SYSTEMS 280ANV036****A FE4ANB006+UI 1200 875 650 35000 14.50 20.50 33400 13.00 31600 1 HRCU-A-CB 207 522 Yes 5462795 Active Systems BRYANT HEATING AND COOLING SYSTEMS EVOLUTION 15 PURON HP BRYANT HEATING AND COOLING SYSTEMS 285BNA036****B FE4ANB006+UI 1050 35400 12.50 15.00 33800 8.50 21600 1 HRCU-A-CB 276 754 Yes 5476675 Active Systems BRYANT HEATING AND COOLING SYSTEMS EVOLUTION 16 PURON HP BRYANT HEATING AND COOLING SYSTEMS 286BNA036****C* FE4ANB006+UI 1050 840 36800 13.20 17.00 35600 9.00 22600 1 HRCU-A-CB 262 754 5537737 Active Systems BRYANT HEATING AND COOLING SYSTEMS EVOLUTION 19 PURON HP BRYANT HEATING AND COOLING SYSTEMS 289BNA036****C FE4ANB006+UI 1210 925 36600 13.70 19.00 37000 10.00 22800 1 HRCU-A-CB 233 678 Yes I would weigh the cost on the Performance 16 or Bryant equivalent, Bryant 280 Extreme, and Bryant 286 Evolution 16 systems. You definitely want the Evolution controller with any of the Evolution systems. The Edge Thermidistat would be fine for Carrier Performance 16 or Bryant equivalent. The dealer who quoted the 002 air handler should be tossed overboard. IMO This post was edited by tigerdunes on Sat, Oct 26, 13 at 8:26

Carrier's Performance 17 AC is just fine. Warranty is same and this condenser is compatible with Infinity Controls. See below 24APA7 Performance Efficiency Up to 18 SEER Limited Warranty 10-year parts limited warranty when properly registered1 ENERGY STAR� Details All Carrier air conditioner products achieving system combinations of 14.5 SEER and 12 EER or higher meet the ENERGY STAR guidelines for efficiency. Proper sizing and installation of equipment is critical to achieve optimal performance. Air conditioners must be matched with appropriate indoor coil components to meet ENERGY STAR criteria.

I would move up to the Preferred series, whether 80% or 95+% efficiency. And you definitely want an ECM blower motor whether var speed or single speed. As of July of 2019 all newer furnaces (all brands) are made with ECM, It's only if some older models were sitting around in storage somewhere... otherwise there is no choice... the choice is being made for you. The up side is better efficiency, the down side is a motor that typically doesn't last as long as a PSC motor and costs more. The PSC motor of furnaces and AH's of yesteryear are going away. https://www.achrnews.com/articles/136459-fer-standards-require-electronically-commutated-motors
