What a full HVAC replacement includes
A full replacement typically means swapping out both the outdoor condenser and the indoor air handler or furnace coil, along with the thermostat and often the refrigerant line set if it's old or undersized. In Shreveport, most homes run a central AC paired with either a gas furnace or an electric heat pump, and the choice between the two affects both upfront cost and monthly operating cost given the region's mild winters and long cooling season.
Because cooling dominates the annual load here, many homeowners find a heat pump makes more sense than a gas furnace and separate AC, particularly if the home doesn't already have gas service. A contractor should size the new system to the home's square footage and insulation rather than simply matching the tonnage of the old unit, since older systems were sometimes oversized or undersized to begin with.
Cost by home size and system type
A straightforward 3-ton central AC or heat pump replacement in a home with existing, functional ductwork generally runs in the $4,800 to $8,200 range installed. Larger homes needing a 4- or 5-ton system, or installations requiring electrical panel upgrades to support a heat pump, run higher.
A full system replacement that includes both the furnace and AC side, common when both units are original to a home and reaching end of life together, typically runs $7,500 to $13,500 for a mid-size home, with the upper end reflecting higher-efficiency equipment or ductwork modifications.
Older homes and ductwork condition
Homes in Highland, South Highlands, and other historic neighborhoods often need ductwork evaluated as part of a replacement, since decades-old ducts may be undersized for modern high-efficiency equipment or leaking significant conditioned air into the attic. Sealing or replacing ductwork adds cost but is often necessary to get the full efficiency benefit of a new system.
Electrical panel capacity is another consideration for older homes, especially if you're upgrading to a heat pump or a higher-SEER system with a larger electrical draw. Get an electrician's assessment as part of the replacement quote if your home still has an older panel.
Permits and code compliance for replacements
A full HVAC replacement inside Shreveport city limits requires a mechanical permit through the Department of Public Works Permits and Inspections Division, with the fee scaled to the contract value of the job. Your contractor should handle filing this as part of the project and should be registered with the city as a trade contractor.
Confirm before work starts that the permit will be pulled, since skipping it can mean a doubled fee plus penalty if discovered, and it can also complicate a future home sale if the buyer's inspector flags unpermitted mechanical work.
Financing, incentives, and getting multiple quotes
SWEPCO's Louisiana HVAC Incentive Program can offset part of the cost of a qualifying high-efficiency system when installed through an approved contractor, so ask any bidder whether they participate and have them include the incentive amount in writing on the quote.
Get at least three quotes for a full replacement, and make sure each one specifies the exact equipment model, SEER2 rating, and whether ductwork work is included, since quotes that look cheaper on the surface sometimes leave out ductwork or electrical costs that get added later.
Typical cost ranges
| 3-ton central AC or heat pump replacement (installed) | $4,800 - $8,200 |
| 4-5 ton central system replacement (installed) | $6,500 - $10,500 |
| Full system replacement (furnace + AC, mid-size home) | $7,500 - $13,500 |
| Gas furnace replacement only | $3,200 - $6,000 |
| Ductless mini-split system (single zone) | $3,500 - $6,500 |
| New ductwork installation (whole home) | $3,500 - $8,500 |
| Electrical panel upgrade (if required for heat pump) | $1,800 - $4,000 |

Common questions
How much does it cost to replace an HVAC system in Shreveport?
For a typical mid-size home replacing both the AC and furnace, expect $7,500 to $13,500, depending on system size, efficiency rating, and whether ductwork needs work.
Is a heat pump a good choice for Shreveport's climate?
Yes, given the long cooling season and mild winters, a heat pump often makes more sense than a gas furnace paired with a separate AC, especially in homes without existing gas service.
Do I need a permit to replace my whole HVAC system?
Yes, a mechanical permit through the City of Shreveport's Permits and Inspections Division is required for most full system replacements inside city limits.
How do I know if my ductwork needs replacing too?
Signs include uneven cooling between rooms, visible damage or disconnected sections in the attic, and unusually high energy bills relative to the size of your home. A contractor can pressure test the ducts to check for leakage.
Are SWEPCO incentives worth factoring into my budget?
They can meaningfully offset the cost of a qualifying high-efficiency system, but only through SWEPCO-approved contractors, and amounts should be confirmed in writing before you count on them.
How long should a new HVAC system last in Shreveport?
With regular maintenance, 12 to 15 years is a realistic expectation given how many hours per year the system runs in this climate.
