Our take on the EcoTemp 70,000 BTU 80% AFUE R-454B Gas Furnace (Upflow & Downflow)

The EcoTemp 70,000 BTU is an 80% AFUE single-stage gas furnace that runs on R-454B refrigerant-ready system designs and installs in upflow or downflow orientation. It uses a multi-speed blower and standard 115V single-phase power, and its 33 1/3-inch cabinet is short enough for tight closets. The best new price is $1,604.00 at The AC Outlet as of November 7, 2026, the only new price listed.

Pros
  • 70,000 BTU output suits mid-size homes
  • 80% AFUE keeps the price well below high-efficiency condensing units
  • Multi-position cabinet works upflow or downflow
  • Short 33 1/3-inch height fits low mechanical spaces
  • Multi-speed blower allows airflow tuning for ductwork
  • Standard 115V single-phase hookup simplifies wiring
Cons
  • 80% AFUE loses more heat up the flue than 90%+ models
  • Single-stage operation means full-blast heating cycles
  • No variable-speed blower for quieter, steadier airflow
  • R-454B readiness matters only if the paired coil and lineset support it
  • Professional installation and venting are required

Questions and answers

Is 70,000 BTU enough for my house?
It typically heats a mid-size home in a moderate climate, roughly 1,400 to 2,000 square feet depending on insulation and windows. A load calculation is the only reliable answer.
Is 80% AFUE worth it over a 90%+ furnace?
Yes if your climate is mild or venting a condensing furnace is hard. In cold climates the higher gas use of an 80% unit can offset the lower purchase price.
Can it be installed downflow?
Yes. The cabinet is multi-position, so it works in upflow and downflow layouts. The installer sets the orientation and venting to match.
Does it work with R-454B refrigerant?
The furnace itself is a gas heat source; R-454B applies to the air conditioner or heat pump coil paired with it. Confirm the coil and lineset are rated for R-454B.
What is the price history?
The only new price listed is $1,604.00 at The AC Outlet as of November 7, 2026. There is no second new price to compare against.
What else do I need to buy?
Plan on a matching evaporator coil or cased coil, a thermostat, venting, and a gas line. Installation labor is separate from the furnace price.
