Furnace replacement in Leander, Texas
A furnace that runs a few weeks a year still wears out. Call to talk replacement with an independent contractor.
Signs that replacement is on the table
A contractor may raise replacement after finding a cracked heat exchanger, a failed control board on an old unit, or repeated no-heat calls in a few seasons. A cracked heat exchanger is a safety matter, so ask to see it.
- The heat exchanger is cracked or rusted through.
- Major parts have failed in two or three winters running.
- The furnace is noisy, uneven or short cycling after repairs.
- The cabinet or flue shows rust or soot.
What a replacement involves
The old unit is disconnected, removed and replaced with a model matched to the house's heating load. Gas lines, venting, the electrical supply and the thermostat are checked and connected to code.
In an attic or closet install, the contractor must also keep the condensate and flue paths clear and sized correctly. A high-efficiency model vents differently from an older one.
Sizing for a mild climate
Winters near Austin are short. The National Weather Service says January is Austin's coldest month, with normal highs in the low 60s and lows in the low 40s. An oversized furnace shuts on and off too fast, so ask for a load calculation instead of a swap by size.

The cost question
Cost follows the furnace's efficiency tier, whether the existing ducts and venting can be reused, gas and electrical work, and the permit. Get written scopes that name the same pieces and compare them side by side.
Questions people ask
Do I need a new air conditioner when I replace the furnace?
Not necessarily. The indoor coil often sits on the furnace, so ask whether the existing coil matches the new unit.
Should I replace a furnace that still runs?
Age alone is not a reason. A technician's inspection of the heat exchanger and the controls is.
