A heat pump is an air conditioner that can run in reverse. In summer it cools like any AC. In winter it pulls heat out of the outdoor air and moves it inside. Florida and the Carolinas have leaned on them for decades, and they have become a common new-install choice in Houston.
Our mild winters are why. A heat pump's efficiency falls off once it gets below freezing outside, but Houston's average winter low is about 45 degrees and we see only a handful of nights a year below 32. That is the climate heat pumps were built for.
Here is how we'd make the call.
The fit, in two sentences
With all-electric utilities or an already small gas bill, a heat pump is almost certainly right for you. If you have cheap natural gas and a furnace under 8 years old, it gets closer, and keeping the furnace may win.
Why heat pumps make sense in Houston
1. The climate suits them
Heat pumps lose efficiency as it gets colder outside. At 50 degrees one runs at 250 to 350 percent efficiency, meaning each $1 of electricity delivers $2.50 to $3.50 worth of heat. At 30 degrees that drops to 180 to 220 percent. At 10 degrees, which is rare here, some units fall back to electric resistance strips at 100 percent.
Houston spends very little of the year below freezing, so a heat pump here runs in its efficient range for nearly the whole heating season.
2. The same equipment cools you all summer
You are buying an AC anyway, and a heat pump is an AC with a heating mode added. In our pricing, a full heat pump system comes in a little under a matching AC-and-furnace system because the furnace drops out of the quote.
3. No combustion safety concerns
There is no flue or gas line to worry about and no carbon monoxide source in the house, so there is no combustion analysis to run each year. Families with elderly parents or small kids tend to like that.
4. Utility rebates still help
The federal 25C credit ended for systems placed in service after December 31, 2025. CenterPoint Energy still offers incentives on qualifying high-efficiency heat pumps. Those rebates start at $200 and are applied on the install invoice through a participating contractor.
5. Future-proof against gas price volatility
With a heat pump, your heating cost follows your electric rate instead of the natural gas market. If you have solar or plan to add it, that matters more.
When a heat pump isn't the right answer
If you have a young, well-maintained gas furnace
Tearing out a gas furnace under 8 years old and in good shape to put in a heat pump rarely pencils out. You'd be throwing away years of useful life. Let it run, and bring the heat pump question back up when the furnace is due.
If your home needs duct or panel upgrades
Heat pumps generally want a bit more airflow than gas furnaces, and swapping out a gas appliance can mean more electrical capacity. An old duct system combined with a full panel can add a significant amount to the install, and that changes the comparison.
If your home is poorly insulated
A heat pump heats more gently than a gas furnace. Coming back from a deep overnight setback, say 60 up to 72 by morning, takes it longer. In a house that loses heat fast, comfort can suffer.
If you don't trust electric grid reliability
People around here still remember the February 2021 outage. A gas furnace with a battery backup on its controls can keep running when the power is out, since the burner needs very little electricity. A heat pump needs the grid. Some customers want gas heat as their backup plan, and we respect that.
Single-stage, two-stage, or variable-speed?
Heat pumps come in tiers, same as air conditioners. Prices below are installed, for a typical 3-ton home.
- Single-stage: $8,000 to $11,000, around 14 to 15 SEER2. Simple and dependable, with less comfort and humidity control.
- Two-stage: $10,500 to $15,000, 16 to 17 SEER2. Better humidity control and quieter.
- Variable-speed inverter: $14,000 to $20,600, 18 to 22 SEER2. Long, steady run cycles give the best comfort and humidity control and the lowest bills.
In Houston we usually point people to two-stage for value and variable-speed as the premium choice. Single-stage makes sense on rentals and tight budgets.
Cold climate heat pumps (CCHP)
Newer "cold climate" models hold rated capacity down to 5 degrees and keep reasonable efficiency to negative 15. For Houston that's overkill, and you'd pay a noticeable premium over a standard heat pump for capability our climate doesn't call for.
One caveat. If your auxiliary heat strips were sized small or left out, a CCHP gives you some margin during a once-a-decade Arctic blast like February 2021. A few customers want that insurance. Most don't need it.
What about hybrid (dual-fuel) systems?
A hybrid pairs a heat pump with a gas furnace. The heat pump carries the load until the outdoor temperature drops below a setpoint, usually 35 to 40 degrees, and then the furnace takes over. Mild-weather efficiency from the heat pump, brute-force gas heat in a cold snap.
In Houston it's a hard sell. The furnace would only fire during the few real cold snaps each year. Meanwhile you're paying for two pieces of equipment and maintaining both, and saving very little, because the heat pump alone would have covered nearly all of the season.
We install hybrids for customers who specifically want gas backup. As a value pick, we don't recommend them.
Operating cost comparison
For a typical 2,500 square foot Pearland home, here is how annual heating and cooling cost generally stacks up, highest to lowest:
- Gas furnace with a 14-SEER AC
- Two-stage heat pump (16 SEER2)
- Variable-speed heat pump (18 SEER2)
- Geothermal heat pump
For most homes the variable-speed heat pump costs less to run than a gas furnace and AC. Low natural gas prices narrow that gap. Solar widens it, since daytime electricity from the panels costs you close to nothing.
What about the "heat pumps don't get warm" complaint?
We hear it. Air coming out of a heat pump's registers runs around 90 to 100 degrees. From a gas furnace it's more like 110 to 130. Both will hold the house at 72, but the furnace air feels hotter on your hand.
A heat pump runs longer cycles at a lower temperature, and a furnace runs short hot ones. Over an hour they deliver the same heat. People switching from gas sometimes say the air "doesn't feel as warm" that first winter, and most come to prefer the gentler, more even heat once they're used to it.
If hot air at the register is a must, a hybrid system gives you furnace heat during cold snaps. So does staying with gas.
What we recommend by household type
All-electric home, no gas service: A two-stage or variable-speed heat pump. Easy decision.
Gas service, AC at end of life, furnace 8+ years old: Go to a heat pump system and retire the furnace. It costs about what an AC-plus-furnace replacement would, and you get better comfort and lower bills.
Gas service, AC at end of life, furnace under 8 years old: Replace the AC only and keep the furnace. Look at a heat pump again when the furnace dies.
New construction: A heat pump. No gas line or flue to pay for, and lower operating cost over the life of the house.
Severe weather concerns: A hybrid system, or stay with a gas furnace and AC. You give up some efficiency for the backup.
What we install
We lead with Goodman and Trane, and we're a Trane Comfort Specialist. Our heat pump tiers line up with the price list above:
- Choice: Goodman single-stage, 14.3 SEER2
- Priority: Goodman or Trane two-stage, 16 SEER2
- Premier: Trane variable-speed, 18+ SEER2, up to the XV20i
Choosing between the top two? Variable-speed if the budget allows, two-stage if it doesn't.
Every tier carries our 12-month parts and labor warranty. After that the manufacturer covers parts for a term that depends on the brand, and the warranties page has the current terms.
