The basics
A gas furnace burns fuel (rated by AFUE); a heat pump moves heat electrically (rated by HSPF2). In mostly-mild Houston winters, heat pumps are often very efficient, with backup for hard freezes.
- Furnace: Burns natural gas; a heat exchanger warms air and the blower distributes it. Efficiency = AFUE.
- Heat pump: Runs the AC refrigerant cycle in reverse to bring heat indoors — efficient in mild cold, with electric or gas ('dual-fuel') backup.
- Repair vs. replacement signs: No/weak heat, short cycling, rising bills, age 15+ years, or any gas-safety concern like a cracked heat exchanger — get that checked immediately.

Your options
Furnace, heat pump, or dual-fuel — what fits Greater Houston?
Gas furnace
Strong, fast heat in deep cold; needs gas service. Doesn't cool, and venting/safety must be correct.
Heat pump
Heats and cools in one system; very efficient in mild winters. Efficiency drops in hard freezes, so backup matters.
Dual-fuel
Heat pump + gas backup — best of both for Gulf-Coast weather; highest upfront cost.
Higher AFUE/HSPF2 lowers operating cost but raises upfront price; payback depends on how cold your winter runs.
