Jacksonville, FL
Heat pumps sized and installed for Jacksonville's climate
Standard, two-stage and variable speed heat pumps that cool through a long humid summer and heat efficiently on the few cold nights, installed with the permit pulled and the JEA rebate filed.
Quick answer
Is a heat pump a good choice for a Jacksonville, FL home?
A heat pump is usually the best choice for a Jacksonville home because heating design temperatures here are roughly 27F to 32F, well within a standard air-source heat pump's range, and the same unit handles cooling all summer. A qualifying 16 SEER2 system also earns JEA's $200 rebate.
Overview
One system for a cooling-heavy climate
Jacksonville sits in a cooling-dominant climate. The system spends most of its life running as an air conditioner, then heats on a few dozen cold mornings each winter. A heat pump does both with one outdoor unit, moving heat out of the house in summer and into it in winter, and it does the heating far more cheaply than electric resistance strips.
Sizing matters more than brand. A heat pump sized to the cooling load with a Manual J calculation runs long, steady cycles that pull humidity out of the air. Oversize it and it short-cycles, the house feels damp, and the compressor wears faster. On the heating side, a correctly set compressor lockout keeps the backup strips off except on the coldest nights.
Cost factors
What drives the cost of a heat pump installation
- Capacity and SEER2Tonnage comes from the load calculation; higher SEER2 and HSPF2 ratings raise equipment cost.
- Single, two-stage or variableVariable speed costs the most up front and handles humidity best.
- Matched air handlerReplacing the indoor unit keeps the system's AHRI rating and rebate eligibility.
- Ducts and electricalUndersized returns or an older panel can add work.
- Coastal grade optionNear the ocean, coated coils add roughly $500 to $1,000 to the outdoor unit.
Published 2026 Jacksonville figures put a full system replacement at $5,800 to $15,000 installed, most homes $9,000 to $13,000, before JEA's $200 rebate.
Options
Which kind of heat pump fits
| Type | How it runs | Humidity control | Up-front cost |
|---|---|---|---|
| Single stage | On or off at full capacity | Adequate when sized right | Lowest |
| Two-stage | Low stage most of the time, high on hot afternoons | Better | Middle |
| Variable speed | Ramps continuously to match the load | Best | Highest |
| Dual fuel | Heat pump plus gas furnace backup | Same as the heat pump chosen | Depends on furnace |
| Ductless heat pump | Wall heads, no ducts | Good per room | Varies by zones |
For JEA's rebate the matched system must reach 16 SEER2 and 8.0 HSPF2 on the AHRI certificate.

What we fix
Heat pump replacement
Most calls are replacements: an older heat pump that's lost efficiency, leaking refrigerant, or on its second compressor. We don't assume the same size is right. A new load calculation often shows the old unit was oversized, especially if windows, insulation or the roof have been updated since. The air handler and coil are usually replaced as a matched set so the AHRI rating holds, which is also what the JEA rebate checks. Old refrigerant is recovered and the equipment hauled away.
Variable speed heat pumps
A variable speed heat pump ramps its compressor and blower up and down instead of running flat out and shutting off. Here, that matters most for humidity. Long, low-speed cycles keep air moving across a cold coil, which pulls much more moisture than short blasts. They're quieter and hold temperature more evenly, and they cost more up front. We'll show you the difference on paper for your house before recommending one, including the rated SEER2 and what that means against your current unit.
Dual fuel with a gas furnace
Some Jacksonville homes have a gas furnace with a separate AC. Replacing the AC with a heat pump keeps the furnace as backup, and the system chooses the cheaper heat source by outdoor temperature. In this climate the heat pump carries nearly all the heating, with gas only on the coldest mornings. It makes sense when the furnace still has life in it. If the furnace is near the end too, a heat pump with electric backup is usually simpler.

Heat pump replacements in older south side subdivisions
Through the 1970s and 1980s, development ran south along the river through Mandarin and across Julington Creek into Fruit Cove. Many of those homes are now on their second or third system, and a lot of them started with an AC and electric strip heat or a small gas furnace. That history shapes the replacement: we check whether the original duct runs can carry the airflow a modern heat pump needs, and whether the existing furnace is worth keeping for dual fuel.

FAQ
Heat pump installation questions
Will a heat pump keep my house warm in a Jacksonville cold snap?
Yes. Design temperatures here are around 27F to 32F, which standard heat pumps handle. Backup strips cover the rare colder night.
Should I replace the air handler too?
Usually yes. A matched indoor and outdoor unit keeps the rated efficiency and rebate eligibility.
Is variable speed worth it here?
In a humid climate it's the best at pulling moisture out of the air, and quieter. It costs more, so we compare it on paper for your house.
Do you file the JEA rebate?
Yes. Qualifying ENERGY STAR heat pumps earn $200 for JEA residential electric customers, and we file the application.
Is there a federal credit for heat pumps in 2026?
No, the Section 25C credit expired December 31, 2025.
How long does a heat pump install take?
Most replacements are completed in a day. Duct changes or electrical upgrades can add a second day.
Can I keep my gas furnace?
If it's in good shape, a dual fuel setup keeps it as backup while the heat pump does most of the heating.
