Options

What We Install

Every home is different. We match the right furnace type to your space, ductwork, and budget.

The most common heating system in the Pacific Northwest. Modern gas furnaces reach up to 98% AFUE, meaning nearly every dollar of gas becomes heat for your home.

  • Up to 98% AFUE efficiency
  • Variable-speed blower motor
  • Two-stage or modulating heat
  • Sealed combustion for safety

Electric Furnace

No gas line? An electric furnace delivers reliable heat with a simpler installation. Lower upfront cost, no combustion, and no CO risk. A solid choice for all-electric homes.

  • No gas line required
  • Zero combustion byproducts
  • Compact footprint
  • Lower installation cost

Dual-Fuel System

Pairs a new gas furnace with a heat pump. The heat pump handles mild weather efficiently; the furnace takes over on the coldest days. The best of both worlds.

  • Best of both fuel sources
  • Maximizes year-round efficiency
  • Heating and cooling in one
  • Lower operating costs than gas alone
