About this collection

An 80% AFUE gas furnace converts 80 cents of every fuel dollar into usable heat, and it remains the practical choice for many homes: lower equipment cost than condensing furnaces, conventional venting, and a strong fit for milder climates, garages, and rental properties where a premium-efficiency furnace may never pay itself back.

This collection features MRCOOL VersaPro variable-speed 80% AFUE furnaces in outputs from 40,000 through 120,000 BTU, available standalone or bundled with a matched MRCOOL Universal, VersaPro, or Hyper Heat central air conditioner for a complete heating and cooling system. Variable-speed blowers run longer, quieter cycles that even out room temperatures and improve summertime dehumidification when paired with the cooling side.

Multiposition cabinets install upflow, horizontal, or downflow, and compact cabinet widths fit most existing plenums. If you are weighing 80% against 96% AFUE, or need help matching furnace output to your square footage and climate, reach out and we will run the numbers with you.
