The Short Answer
If you are replacing an existing all-electric HVAC system in South Florida and you are buying a new system in 2026, a heat pump is almost certainly the better choice. That is not a blanket statement — there are real exceptions we will get into — but for the typical Broward County home with existing ductwork and an electric air handler, a heat pump gives you better efficiency, meaningful rebates, and no meaningful downside in our climate.
The market has already voted: heat pump market share in Florida climbed from 48% of new installations in 2021 to 61% in 2025. That is not marketing. That is homeowners and contractors running the math and landing in the same place.
Here is exactly how we arrive at that conclusion — and when we would tell you otherwise.
How Heat Pumps Work (and Why Florida's Climate Is Ideal for Them)
A heat pump is not a heater. It is a refrigerant cycle that runs in both directions. In cooling mode, it works identically to a standard air conditioner — it pulls heat from inside your home and dumps it outside. In heating mode, it reverses that process: it extracts heat energy from the outdoor air and moves it inside.
That last part surprises people. "But it's the outdoor air — it's cold." Here is the thing: even at 55°F, outdoor air contains a tremendous amount of heat energy. A heat pump can extract it efficiently. This is where the efficiency numbers come from: a heat pump delivers around 3 BTUs of heat energy for every 1 BTU of electricity consumed — roughly 300% efficiency. A standard electric resistance heating strip converts 1 BTU of electricity into exactly 1 BTU of heat. That is 100% efficiency, which is actually the worst possible outcome in thermodynamics.
Now apply that to Florida's actual winters. Our "cold" season runs roughly December through February. Average low temperatures in South Florida during that stretch are 55°F to 65°F. Heat pumps are highly efficient at those temperatures — there is no performance degradation until you get below 40°F, which we rarely see. This is why Florida is arguably the best climate in the country for heat pump performance. You get the full efficiency benefit of the heating cycle during exactly the conditions you will actually experience.
Central AC + Separate Heating vs. Heat Pump: The Real Cost Comparison
Let's put some numbers on this. A standard central AC system in South Florida runs your cooling with refrigerant, but for heat it typically relies on electric resistance strips built into the air handler. When those strips kick on — usually a few months a year — your electric bill notices immediately. A 10 kW strip heater running 3 hours a day for 90 days costs roughly $108–$135 at FPL rates. Not catastrophic, but not nothing either.
A heat pump running in heating mode for the same period, at 300% efficiency, delivers that same warmth for about $36–$45. That is a 30–40% reduction in heating costs. On its own, the annual dollar savings may be modest — $60–$90 per year depending on your usage. But combine that with the rebate stack below and the payback calculation changes significantly.

Side-by-Side Comparison
| Category | Central AC (with resistance heat) | Heat Pump Recommended |
|---|---|---|
| Install Cost | $3,500 – $10,000 | $4,500 – $12,000 |
| Efficiency Rating | Up to 21 SEER2 (cooling only) | Up to 22+ SEER2, HSPF2 10+ (heating) |
| Cooling Performance | Excellent | Identical — same refrigerant cycle |
| Heating Performance | 100% efficiency (resistance strips) | ~300% efficiency in FL temperatures |
| Available Rebates 2026 | FPL rebate (efficiency-based only) | $2,000 federal tax credit + $150 FPL rebate |
| Best For | Homes with gas heat or ductless situations | Most South Florida homes replacing all-electric systems |
The 2026 Rebate Stack: How to Get $2,150+ Back on a Heat Pump Install
This is where the heat pump math gets genuinely compelling. In 2026, two rebate programs stack together for qualifying installations:
- Federal Energy Efficient Home Improvement Credit (25C): Up to $2,000 tax credit for qualifying heat pump systems. To qualify, the unit must meet CEE Tier 1 standards — typically 15.2 SEER2 or higher for split systems. You claim this on IRS Form 5695 when you file your taxes.
- FPL High-Efficiency Heat Pump Rebate: $150 rebate for units rated 16 SEER2 or higher. Submit through FPL's rebate portal after installation. Processing takes 4–6 weeks.
Combined, that is $2,150 in rebates available on a qualifying heat pump install. If your system costs $7,000 installed, the effective cost after rebates is $4,850 — comparable to or better than a mid-tier AC-only system with no rebates.
Have your contractor confirm the model number qualifies for CEE Tier 1 before signing the contract. Get the manufacturer's certification statement — you'll need it for IRS Form 5695. Submit the FPL rebate the day after installation using your permit number and invoice. Don't leave $2,150 on the table because a contractor didn't walk you through the paperwork.

When Central AC Makes More Sense
We install heat pumps every day, but we are not going to pretend there are no situations where a straight AC replacement makes more sense. Here is when we would point you toward central AC instead:
You Already Have a Gas Furnace
If you have a gas furnace paired with a central AC coil, replacing just the AC with a heat pump is not a straightforward swap. The heat pump's reversing valve would conflict with the existing furnace control board, and in most cases you would need to replace the entire air handler as well. At that point the cost premium over a straight AC replacement climbs sharply. For a home that already has efficient gas heat, a high-SEER2 AC-only unit often makes more economic sense.
You Are Budget-Constrained Right Now
The heat pump upfront premium is $1,000–$2,000 depending on unit and configuration. If you have a tight budget and need the system replaced immediately, the $2,150 in rebates do not help you today — the tax credit comes back at filing time and the FPL rebate takes 4–6 weeks. A good AC-only install at a lower price point is a perfectly sound decision.
Your Existing Ductwork Cannot Handle It
This one is critical and gets overlooked far too often.
Do not let a contractor swap in a heat pump without verifying your duct system can handle it. Heat pumps in heating mode move air at slightly higher static pressure than AC-only systems. Undersized or deteriorated ducts that were marginal with your old AC unit can become a real problem with a heat pump, causing noise, reduced efficiency, and premature system wear. Any reputable installer should do a Manual J load calculation and a duct leakage test before signing the contract.
What About Ductless Mini-Split Heat Pumps?
Ductless mini-splits deserve their own conversation, but the short version: they are an excellent choice for additions, converted garages, older homes without existing ductwork, or supplementing a central system in a problem zone. In South Florida, we see them frequently in Florida rooms, home offices, and master suites where the central system cannot keep up.
A properly sized mini-split heat pump in a Broward County home runs at very high efficiency — many are rated at 20+ SEER2 — and they qualify for the same federal tax credit as ducted systems. For whole-home replacement, they require multiple indoor head units and a more complex installation, which pushes costs up. But for targeted comfort zones, they are hard to beat.
For heat pump installation across Broward County, we handle both ducted and ductless configurations and can tell you within 15 minutes of looking at your home which approach makes more sense.
Frequently Asked Questions
The Bottom Line for South Florida Homeowners
Heat pumps have earned their dominant position in the Florida new-install market. The cooling performance is identical to a central AC. The heating efficiency is dramatically better than resistance strips. The rebate stack in 2026 reduces the upfront premium significantly. And Florida's mild winters are the single best climate condition for heat pump performance — you never push the system into the low-temperature range where efficiency starts to drop.
For most Broward County homes replacing an all-electric system, the heat pump is the right call. For homes with gas heat already in place, or properties with serious duct issues, a standard central AC installation may still be the smarter play.
