How furnace installation works
What a furnace installation job looks like in Gresham.
A furnace install isn't just a box swap. We start with a Manual J load calculation to right-size the system for the actual house — square footage, insulation R-values, window count, climate zone. Skipping that step is how most homes end up with oversized equipment that short-cycles and dies early.
Equipment-wise, we install Trane and American Standard high-efficiency gas furnaces (92–97% AFUE) by default, with a value-tier alternative when the budget calls for it. Vent sizing, gas-line check, combustion analysis, and electrical all get installed to factory spec. That's the reason warranties stay valid past year 10.
Permit pulled, inspection scheduled, manufacturer warranty registered in your name. Paperwork lands in your inbox before we leave the driveway. Free in-home estimate, Wells Fargo financing available.

- Energy Trust of Oregon offers rebates on high-efficiency 95%+ AFUE gas furnaces. Heat pumps qualify for substantially larger incentives.
