Replace your furnace when it is old, needs repeated or costly repairs, or has a cracked heat exchanger. Most gas furnaces last roughly 15 to 20 years. A licensed provider should size the new unit to your home and check the ducts, vent and gas line before installing.
Signs it may be time to replace your furnace
- The furnace is about 15 years old or older
- You have paid for several repairs in a short time
- A technician found a cracked heat exchanger
- Heating bills keep rising with no change in use
- Rooms are uneven, noisy or never get comfortably warm
- There is rust, soot or water around the furnace
- Replacement parts are hard to find or very costly
- You want better efficiency, quieter operation or a smarter thermostat
Replacement options to discuss
Gas furnace
The most common choice in many Houston homes. Furnaces list an efficiency rating (AFUE), and higher-efficiency models burn less gas for the same heat.
Heat pump
Moves heat instead of burning fuel and also cools in summer. Many Houston homes use one system for both seasons, often with electric backup heat for freezes.
Dual-fuel system
Pairs a heat pump with a gas furnace. The system uses whichever is more efficient at the time, which can suit homes that want strong heat in a freeze.
Right size and ductwork
A unit that is too big or too small wastes energy and wears out faster. Ask the provider how they size the system and whether your ducts need work.
What a good replacement visit should include
- A look at your current furnace, vent, gas line and electrical setup
- A load calculation or sizing explanation, not just "same size as before"
- Written options with brands, efficiency ratings and warranty terms
- Duct, thermostat and filter recommendations
- Permit and inspection details where the city or county requires them
- A clear installation timeline and a written total
Compare at least two written quotes when you can.
Do not wait if
- A technician says the heat exchanger is cracked. A cracked exchanger can leak carbon monoxide.
- A carbon monoxide alarm sounds. Get everyone outside and call 911.
- You smell gas. Leave and call 911 or your gas utility from outside.
- The furnace is no longer working and a freeze is forecast. Ask about temporary heat while you decide.
What affects the price of a new furnace
- System type (gas furnace, heat pump or dual-fuel)
- Efficiency level and brand
- Size and number of stages or speeds
- Ductwork, vent or gas line changes
- Permits, removal of the old unit and warranty options
Ask the provider for the price, any diagnostic or trip fee, and their Texas license number before they start work.
Houston timing tip
In Houston, the heating season is short, so many homeowners replace a furnace only when it fails. Planning ahead lets you compare quotes calmly instead of choosing in a rush during a freeze. Since many homes use one system for both heat and cooling, ask whether replacing the whole system makes sense.
Furnace Replacement FAQs
How long does a furnace last?
Many gas furnaces last about 15 to 20 years with regular care. Houston furnaces may run fewer hours each year than those in colder states, but age, dust and humidity still wear parts out.
Should I repair or replace my furnace?
Consider age, repair cost, safety and efficiency. A cracked heat exchanger, repeated breakdowns or a very old unit usually points to replacement. Ask the provider to explain both options in writing.
Can I switch from a furnace to a heat pump?
Often yes. A heat pump heats and cools, and many Houston homes already use them. A provider can check your ducts, electrical capacity and whether you want backup heat for freezes.
How long does installation take?
Many straightforward furnace swaps take a day or less. Changes to ducts, venting or gas lines can take longer. Ask the provider for a schedule before you agree.
