Our take on the 88,000 BTU Modulating Upflow/Horizontal ECM Variable Speed Gas Furnace 97% AFUE 120/60/1 CFM: 1362

This is a two-part furnace: an 88,000 BTU input, 85,000 BTU output modulating gas furnace rated at 97% AFUE, with an ECM variable-speed blower and an upflow/horizontal cabinet. Modulating operation and a variable-speed motor let it run at low fire most of the time, which means steadier heat and quieter cycles than a single-stage unit. It uses non-communicating controls, so it works with standard thermostats rather than a proprietary communicating system. The best new price is $1,229.00 at Surplus City Liquidators as of November 7, 2026, and only one store lists it new, so there is no meaningful price history to compare against.

Pros
  • 97% AFUE condensing efficiency cuts gas use versus an 80% furnace
  • Modulating gas valve runs at low fire for steadier temperatures
  • ECM variable-speed blower is quieter and uses less electricity
  • Upflow/horizontal cabinet fits either orientation
  • 85,000 BTU output covers most mid-size homes in cold climates
Cons
  • Condensing design needs a drain and PVC venting, which raises install cost
  • Non-communicating controls rule out advanced communicating thermostats
  • Propane conversion kit 68W77 is not included
  • Only one store lists it new, so price shopping is limited
  • 165 lbs and a 21-inch-wide cabinet need two people and a wide path

Questions and answers

Is 85,000 BTU output enough for my house?
It suits most homes in cold climates up to roughly 2,500 to 3,000 square feet, but sizing depends on insulation, windows and ductwork. Have a contractor run a load calculation before buying.
Does it work on propane?
Yes, but only with the 68W77 propane conversion kit, which is not included. Budget for the kit and a qualified conversion.
What venting does a 97% furnace need?
It condenses, so it vents through PVC pipe and needs a drain for condensate. That usually means a different flue path than an old metal chimney.
Can I use my existing thermostat?
It uses non-communicating controls, so a standard single- or two-stage thermostat works. You lose the finer control a communicating thermostat would give.
What is in the box?
The furnace in its manufacturer packaging. The propane kit, thermostat, vent pipe and drain parts are separate purchases.
When is it cheapest?
Only one store lists it new at $1,229.00 as of November 7, 2026, so there is no price history to time a drop against. Compare install quotes as much as the unit price.
Where is the 88,000 BTU Modulating Upflow/Horizontal ECM Variable Speed Gas Furnace 97% AFUE 120/60/1 CFM: 1362 cheapest?
