A new furnace for a 2,000 sq ft house is quoted after an in‑home assessment because home layout, ductwork condition, and efficiency goals set the total installed price. The largest factor is properly sizing the furnace (BTUs) to your heating load and selecting an efficiency rating that fits your utility and comfort targets. Fuel type and whether you’re replacing only the furnace or an entire HVAC system also change scope. We install and replace furnaces across the Austin area and size systems for local conditions as part of the quote. Free estimates are available, and current offers can reduce costs, including a free Lennox furnace with a qualifying Lennox system purchase.
Your written estimate should spell out:
- Static pressure readings and any duct repairs needed.
- Venting and gas line requirements specific to your home.
- Installation location constraints (attic, closet, or garage).
- Optional upgrades like whole‑home HEPA filtration or attic insulation.
