Replace the dying furnace once, not every 15 years

If your furnace or heat pump is about to croak, you are standing at the cheapest moment to switch. You were going to spend five figures anyway; the question is whether the new system ever pays you back.

Why a retrofit is easy

No flame means it fits where furnaces cannot

A WaterFurnace unit burns nothing, so there is no exhaust to vent and no combustion-air clearance to respect. It installs in closets, crawl-space corners, and rooms a fossil furnace could never occupy.

Already have ductwork? You are starting the race ahead of the pack; the unit connects to it directly. No ductwork? We install it. And if you have ever wanted warm floors in February, one of our units pairs forced air with radiant in-floor heating from the same box.

  • No combustion, no flue, installs virtually anywhere
  • Reuses your existing ductwork when you have it
  • Radiant in-floor heating available alongside forced air
  • Old equipment hauled out as part of the job
