A Coastal Georgia heat pump quote is a stack of decisions wearing a single number, and this guide unstacks it. The bands run from a few thousand dollars for a single-zone ductless unit in a Starland apartment conversion to the deep five figures for a whole-home conversion on Isle of Hope, and the spread between honest quotes for the same house is usually explained by scope rather than greed. What follows are the bands, the variables that move a project between them, where the Georgia Power money belongs in the arithmetic, and the one line item this market adds that the inland markets never see: salt air.
The Bands
| Project type | Typical Coastal Georgia range |
|---|---|
| Single-zone ductless | $3,500 to $7,000 |
| Multi-zone ductless, two to four heads | $8,000 to $16,500 |
| Ducted changeout, usable ducts | $7,000 to $14,000 |
| Whole-home conversion, new or heavy ductwork | $13,000 to $25,000 |
| Dual fuel, heat pump plus gas furnace | $10,500 to $20,000 |
The bands are wide because the houses are. A Pooler two-story with clean trunks sits at the bottom of the changeout band; a Victorian District house asking for three heads and routing that respects a facade sits high in the multi-zone band for reasons a site visit makes obvious. Treat any figure quoted before a measurement as a genre of fiction.
What the Climate Charges For
Savannah's design nights sit in the upper twenties, the gentlest winter exam in this guide's family, which means nearly every quality variable-speed machine passes the capacity test in our cold-weather guide without a cold-climate premium. What the climate charges for is the cooling season, which runs longer here than almost anywhere the technology is sold: months of heat and heavy coastal humidity that make dehumidification at part load half the job description. The winter's contribution is the occasional real snap, a few nights that find lazy backup staging and bill it through strip heat, cheap to prevent at specification time.
The Salt Air Line
The islands and the waterfront streets, Tybee Island, Wilmington Island, Isle of Hope, Thunderbolt, add a variable no inland quote carries: the outdoor unit lives in salt air, and salt air eats coils and cabinets that were not specified for it. The competent coastal bid addresses it in writing: equipment placement out of direct spray where the lot allows, coastal-duty coatings or corrosion-resistant cabinet options where offered, and a maintenance rhythm that includes rinsing the coil. This costs little at specification time and buys years of equipment life. A bid for a Tybee address that never mentions salt has not visited Tybee.
Where the Rebates Fit
Georgia Power's Home Energy Improvement Program pays 50% of installed cost up to $1,000 for an air-source conversion, in application windows with hard closing dates, the most recent of which closed July 24, 2026, so the window check comes before the arithmetic. Elsewhere in this storefront's territory the map changes: TVA distributor money up to $800 in the far north, Jackson EMC's $400 around Gainesville, all mapped with conditions in our rebates guide. The correct position for any of it is last: price the project to stand on its own numbers, then subtract a rebate whose window and amount were confirmed at quote time and appear as a named line. A bid citing the federal credits that ended December 31, 2025 is stale on its face.
The Panel Question
The older stock, Historic District, Victorian District, Starland, Ardsley Park, often runs 100 amp service, and a whole-home conversion can force new circuits or a service upgrade with utility coordination and lead time attached. Panel work runs roughly $1,500 to $4,000 when needed, and the honest bidder opens the panel at the site visit and prices what they find. The evasive one discovers it after signing, as a change order. Ask in the first call: what will you check on my panel, and will any panel work be itemized?
Ducts, Measured or Routed
Pooler, Richmond Hill, Georgetown, Garden City, and the newer subdivision rings mostly carry reusable trunks, but builder-grade ducts sized to a construction budget can choke a heat pump's steadier flow, and in this climate undersized returns complain loudest in July. A static-pressure reading before sizing costs little and prevents the most common comfort complaint in the changeout band. In the historic stock, where usable ducts thin out, the cost driver becomes head placement and line-set routing, decided by someone who can point to work in houses like yours, ideally houses with review boards. Both answers belong in writing before a price does.
The Most Common Trigger: The Air Conditioner Dies in July
Coastal Georgia buys most of its heat pumps under duress, in summer, when the old air conditioner quits during a heat wave. That timing is exactly why the specification discipline matters. The replacement dollar was being spent anyway; the only question is whether it buys a cooling-only machine plus another decade of the old heating arrangement, or one variable-speed system that handles both seasons. The panic purchase copies the old tonnage and regrets it for fifteen years; the measured purchase takes one extra afternoon and gets the humidity right.
Dual Fuel and the Gas Question
Households on the gas mains with a functioning furnace face the closest race in the ledger, run honestly in our fuel comparison: gas is cheap heat, and the conversion cases that clear are usually calendar cases, the air conditioner at end of life buying a machine that heats too. Dual fuel, a heat pump carrying the season with the furnace held for the coldest snaps, is a legitimate configuration here, though at upper-twenties design temperatures the furnace's share of the year is small. One program footnote for the Hall County edge of the territory: Jackson EMC's rebate excludes dual-fuel systems, so members should see both configurations priced.
The Cheaper Levers First
Two line items routinely outperform an extra ton of capacity per dollar. Air sealing and attic insulation shrink the load the machine must cover, and in a region where the attic spends half the year at oven temperatures, insulation pays its way through every cooling month. A contractor who suggests envelope work before upsizing equipment is optimizing your money; one who solves every load with tonnage is optimizing their invoice.
Operating Cost, the Second Price
The purchase price is the number on the quote; the operating price arrives monthly for fifteen years. A properly sized variable-speed machine at Georgia rates undercuts strip heat and propane decisively and races gas closely, and it earns most of its keep in this market through the cooling season it replaces the old air conditioner for. The sizing keeps the operating price honest: oversized cooling short-cycles and leaves the house clammy through the longest season on the calendar, and that mistake is this coast's signature error.
Three Quotes, Read Correctly
Collect three bids and expect the market to sort itself. One arrives fast, low, and paperless; it has skipped the load calculation and its price is an estimate of your patience. One arrives high and thorough; make it justify its scope line by line, which a good contractor does without flinching. The signable bid usually produced documents before being asked: a room-by-room load calculation, published capacity at the design condition, the program window confirmed in writing, panel and duct findings recorded, and for the islands, the salt answer. The vetting sequence lives in our contractor guide. Price matters, but only between bids that passed.
The Short Version
Single-zone ductless from about $3,500; whole-home conversions to the mid twenties; the historic stock pays a routing premium, the subdivision rings pay for duct corrections when the measurement demands them, and the islands pay a small salt-air premium that repays itself in equipment life. Georgia Power's HEIP money is real but windowed, so it gets confirmed, not assumed, and subtracted at the end of arithmetic that already cleared. The climate charges hardest for summer. Spend the extra afternoon on the load calculation; it is the cheapest component in the entire project.
