What furnace installation & replacement involves
We size to the house, not the label on the old unit. That means a room-by-room look at the building, then equipment selection, then venting and gas piping to code — with the old system removed and hauled away.
Right-sized furnace replacement with proper venting, gas piping and airflow — not a swap-and-go.
Common problems and warning signs
- Persistent short cycling that survives every repair
- Venting that doesn't meet current code
- Efficiency well below what modern equipment delivers
- A second failure on the same major component
- You're already planning other work and want it done at once
What the repair involves
If the existing furnace can be repaired safely and economically, that's our recommendation — replacement is for equipment that's unsafe, obsolete or repeatedly failing.
When replacement makes sense
You get equipment options with real differences explained — single-stage versus two-stage, standard versus high-efficiency condensing — and an honest read on whether the upgrade pays back in this house.
