Replacing a Furnace in Austin: What to Know First

Most gas furnaces in Austin sit in the attic or a hall closet, with the air conditioner’s indoor coil mounted right on top. So a furnace replacement is rarely just about heat: the furnace blower also moves the air for your AC all summer long. When we replace a furnace, we treat the furnace, the coil and the ductwork as one system.

Gold Eagle Services has served Central Texas homes since 2017 as a Mitsubishi Electric Diamond Contractor and GE Elite Dealer. We install new gas furnaces, heat pumps and dual fuel systems that pair the two.

Want to see your options before anyone visits? Build your system online to compare a gas furnace, a heat pump or a dual fuel setup for your home and request an estimate. Our local team reviews every build and confirms the details at an in-home visit.

When Is It Time to Replace Your Furnace?

A furnace that still lights isn’t always a furnace worth keeping. Replacement is worth a conversation when you see:

  • A cracked heat exchanger or other safety finding from a technician
  • Repeated repairs to igniters, flame sensors, control boards or the inducer motor
  • A blower that struggles to move air in summer as well as winter
  • Rooms that never get warm, or short cycling on cold mornings
  • Rising gas bills without a change in how you use the heat
  • An older AC and furnace that are both nearing the end of their life

If your furnace stopped working tonight, start with our furnace and heating repair page. Plenty of furnaces need a part, not a replacement, and when that is the case we will say so. For a deeper look at the decision, read Repair or Replace? Deciding What’s Best for Your HVAC System.

Gas Furnace, Heat Pump or Dual Fuel: Which Fits Your Home?

If your home already has natural gas, you have three main paths when the furnace needs replacing:

  • A new gas furnace paired with an air conditioner. Strong, hot heat on the coldest nights in a setup you already know. Best when gas is in place and you want to keep it.
  • An all-electric heat pump with backup heat strips. One outdoor unit heats and cools, and you can remove gas from the HVAC system. See Heat Pumps vs. Electric Resistance Heat.
  • A dual fuel system: a heat pump for most of the year and a gas furnace for the coldest days, controlled by one thermostat.

Austin has a long cooling season, a short heating season and the occasional hard freeze. That mix is why many homeowners look hard at heat pumps and dual fuel when a furnace fails. Read Can a Heat Pump Keep Up With a Texas Freeze? for how heat pumps handle cold snaps, or compare all three side by side in Build Your System.

How We Size and Install a New Furnace

An oversized furnace short cycles and leaves some rooms cold; an undersized one runs nonstop on a freezing night. We size new equipment with an ACCA Manual J load calculation instead of copying the old nameplate. A furnace replacement with us includes:

  • Manual J load calculation and a check of your ductwork and returns
  • Matching the furnace blower to your AC or heat pump coil
  • Gas line, venting and combustion air checked against code
  • Condensate drain and PVC venting for high-efficiency condensing furnaces
  • Permits and inspections where required
  • Start-up testing, including combustion and carbon monoxide checks at the equipment
  • Thermostat setup and a walkthrough of your new system

If the ducts are leaking or undersized, a new furnace cannot fix that on its own. In most Austin attics that means checking the ductboard plenum and flex runs while the old furnace is out. Learn more about our ductwork services.

80% or 95% AFUE: Which Furnace Efficiency Makes Sense in Austin?

AFUE tells you how much of the gas a furnace turns into heat for your home. Standard furnaces are rated around 80% AFUE. Condensing furnaces, rated 90% and above, pull extra heat out of the exhaust before it leaves the house.

In colder climates, the higher efficiency usually pays for itself. In Austin, with only a few months of real heating, it depends on your home. A condensing furnace also needs PVC venting and a condensate drain, which adds work in an attic installation. We put the higher purchase price next to the gas it saves, so you can see whether the upgrade earns its keep in your house.

Replacing the air conditioner at the same time? The outdoor unit and coil carry their own efficiency ratings (SEER2, plus HSPF2 for heat pumps), and new systems use newer refrigerants as R-410A is phased down. See What Do SEER and SEER2 Mean?.

What Does a New Furnace Cost in Austin?

What drives the cost of a furnace replacement:

  • Furnace size, based on your home’s load calculation
  • Efficiency (80% or condensing 90%+ AFUE) and single-stage, two-stage or variable-speed blowers
  • Whether the AC or heat pump and the indoor coil are replaced at the same time
  • Venting, gas line and condensate work
  • Attic or closet location and access
  • Duct repairs or modifications
  • Permits and inspections

Frequently Asked Questions

Many gas furnaces in Central Texas last 15 to 20 years or more, because our heating season is short. Age alone is rarely the deciding factor. Condition, repair history, safety findings and the age of the AC paired with it usually matter more.
