In brief
On the Gulf Coast, heat pumps deliver 2.5–4 units of heat per unit of electricity vs. a furnace's 0.96 — a massive efficiency advantage in our mild winters. For most homes here, a heat pump is the clear financial winner.
August took us across Galveston, Tiki Island, Texas City, Pearland, League City, and Friendswood for 99 jobs, and about two thirds of them were diagnostics. Here is what that mix says about how buildings and equipment behave on 100 degree days, and what it is worth checking on your own system.

Every fall, when the first cool front drops temperatures into the 50s and homeowners in Friendswood start thinking about heating, the same question comes up: should I stick with my gas furnace, or would a heat pump be a better fit?
The answer, for most Gulf Coast homes, is more straightforward than you might expect. Our climate gives heat pumps a massive efficiency advantage that most of the country doesn't share — and many homeowners are paying significantly more than they need to for winter heating simply because a gas furnace came with the house.
Let's break down how each system works, where each one excels, and which one makes financial sense for your situation.
A heat pump doesn't generate heat — it moves it. In cooling mode, it works identically to a standard air conditioner: it absorbs heat from your indoor air and releases it outside. In heating mode, it reverses the process, extracting heat from the outdoor air and pumping it inside.
This is the part that confuses people. "How can it pull heat from cold air?" The answer is that even 40°F air contains a substantial amount of thermal energy. A heat pump's refrigerant, which is much colder than the outdoor air, absorbs that energy through the outdoor coil and compresses it to a much higher temperature for indoor delivery.
The key advantage: moving heat takes far less energy than creating it. A modern heat pump delivers 2.5-4 units of heating energy for every 1 unit of electricity consumed. A gas furnace, even a high-efficiency model, converts at most 0.96 units of gas energy into 0.96 units of heat — and that's before accounting for the cost difference between gas and electricity.
A gas furnace ignites natural gas in a combustion chamber and passes the hot combustion gases through a heat exchanger. Your home's air is blown across the outside of the heat exchanger, absorbing the heat, and distributed through the duct system. The combustion byproducts (carbon dioxide, water vapor, and trace gases) are vented outside through a flue pipe.
Furnaces are rated by AFUE — Annual Fuel Utilization Efficiency. A 96% AFUE furnace converts 96 cents of every dollar of gas into usable heat. The other 4 cents goes up the flue. That sounds efficient, and it is — but it's still fundamentally limited by combustion chemistry. A furnace cannot exceed 100% efficiency because it's creating heat from fuel.
Heat pump efficiency decreases as outdoor temperatures drop. At around 25-30°F, a standard heat pump reaches its "balance point" — the temperature where it can no longer extract enough heat to keep up with the home's heating demand without supplemental help. Below that point, a backup heat source (electric resistance strips or a gas furnace) kicks in.
Here's where the Gulf Coast gives heat pumps an enormous advantage: we almost never hit the balance point.
Friendswood's average winter low temperatures tell the story:
The temperature drops below freezing only 10-15 nights per year in a typical winter, and sustained freezes below 25°F are rare — maybe 1-3 nights annually. That means a heat pump operates at or near its peak efficiency for 95%+ of the heating season.
Compare that to a home in Chicago, where winter lows regularly reach single digits. Up there, a heat pump spends much of the winter at or below its balance point, relying heavily on expensive backup heat. The economics look very different.
Many homes in Towne Lake and Nottingham Country in Friendswood were built with gas furnaces as the standard heating system. This made sense from a construction standpoint — builders install what they know, and gas furnaces have been the default for decades. But for homeowners evaluating replacements, the calculus has shifted significantly.
Pro Tip: A heat pump replaces both your air conditioner and your furnace in a single system. When your AC needs replacement, that's the ideal time to evaluate switching to a heat pump — you're already paying for a new outdoor unit and potentially a new indoor coil. The incremental cost of a heat pump over a standard AC is often just $1,000-$2,000, and the heating savings pay that back quickly.
Despite the Gulf Coast's heat pump-friendly climate, there are scenarios where keeping a gas furnace is the better choice:
Existing gas infrastructure with a newer furnace. If your furnace is less than 8-10 years old and performing well, replacing it with a heat pump before end of life doesn't make financial sense. Plan for a heat pump when the furnace reaches replacement age.
Very large homes with high heating loads. Homes over 3,500-4,000 square feet with high ceilings and large window areas may have heating demands that exceed what a single heat pump can deliver during our coldest nights. Dual-zone heat pump systems or a dual-fuel approach can address this.
Areas with very low natural gas rates. If your gas rate is substantially below the regional average (sometimes the case with municipal utilities), the cost advantage of a heat pump narrows. Run the numbers with your actual utility rates.
For homeowners who want heat pump efficiency but aren't ready to give up their gas furnace entirely, there's a middle path: the dual-fuel system.
A dual-fuel system pairs a heat pump with an existing gas furnace. The heat pump handles heating above 35-40°F (which is the vast majority of our winter). On the rare nights when temperatures drop below the crossover point, the system automatically switches to the gas furnace.
This approach gives you:
When to Call a Pro: Choosing the right heat pump size and configuration for your home requires a proper load calculation — not guesswork. An undersized heat pump won't keep up on cold nights, while an oversized unit short-cycles and wastes energy. Ask your technician about heat pump evaluation and sizing based on your home's specific characteristics.
Let's look at approximate annual heating costs for a typical 2,200 sq ft Friendswood home:
Gas furnace (96% AFUE):
Heat pump (HSPF2 9.0):
Annual savings with heat pump: $150-$250
Those savings compound over a 15-year system lifespan to $2,250-$3,750 — which more than covers the incremental cost of choosing a heat pump over a standard AC system. And this doesn't account for the elimination of furnace maintenance costs, annual gas safety inspections, or the reduced carbon footprint.
For most Friendswood homeowners, the decision tree is simple:
Absolutely. In cooling mode, a heat pump dehumidifies exactly like a standard air conditioner — the evaporator coil condenses moisture from the air. A properly sized heat pump handles Gulf Coast humidity just as effectively as any conventional AC system. In heating mode, humidity isn't a concern because you're warming the air, which naturally lowers relative humidity.
With proper maintenance, 15-20 years is typical for quality equipment. That's comparable to a standard AC system's lifespan and usually longer than a gas furnace in our humid, salt-influenced environment. The heat pump advantage is that you're maintaining one system instead of two.
Your electric bill will increase, but your gas bill will decrease by a larger amount — resulting in lower total utility costs. The net savings depend on your specific gas and electric rates, home size, and insulation quality, but virtually all Gulf Coast homes see positive net savings with heat pump heating.
Newer heat pumps use R-410A or the upcoming R-454B refrigerant, both of which are more environmentally friendly than older R-22. If you're replacing an R-22 system, switching to a modern heat pump gives you better efficiency, better environmental performance, and eliminates the problem of finding increasingly expensive R-22 for recharges.
The Gulf Coast climate was practically designed for heat pump technology. If you're evaluating your heating options, the numbers almost always point the same direction.
