Rebates & Incentives
Stack every dollar you're owed
Yes, Charleston-area homeowners can still lower the cost of new HVAC and water heating equipment in 2026, but the landscape changed after the federal 25C tax credit ended for installations completed after December 31, 2025. Today the real savings come from your electric utility — Dominion Energy South Carolina, Berkeley Electric Cooperative, or Santee Cooper, depending on where you live — plus rotating Daikin manufacturer rebates and South Carolina's state-run HOMES and HEAR rebate programs, which are expected to launch during 2026. Holy City Heating & Air can tell you which utility serves your address, which programs your equipment qualifies for, and how to pair any rebate with Goodleap financing.
Program details verified as of July 2026 — always confirm current terms before you buy.
Heat Pumps
Yes. Heat pumps have the most rebate support of any purchase in the Charleston market: Dominion Energy South Carolina, Santee Cooper, and Berkeley Electric Cooperative each run residential heat pump or dual-fuel incentives, and South Carolina's income-based HEAR rebates for heat pumps are expected to launch during 2026. Daikin also runs rotating instant rebates on qualifying systems installed by a Daikin Comfort Pro.

Federal 25C Energy Efficient Home Improvement Credit (ended)
Federal (IRS)
Terminated — not available for equipment placed in service after December 31, 2025
The federal 25C tax credit, which covered 30% of the cost of qualifying heat pumps, air conditioners, furnaces, and heat pump water heaters up to annual caps, was terminated by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not allowed for any property placed in service after December 31, 2025 — so equipment installed in 2026 does not qualify.
If your qualifying system was installed on or before December 31, 2025, you can still claim the credit on your 2025 federal return using IRS Form 5695. For 2026 installations, look to utility, state, and manufacturer programs instead.

South Carolina HOMES & HEAR Home Energy Rebates (SC Energy Office)
State of South Carolina (SC Energy Office)
Not yet open as of July 2026 — launch anticipated during 2026; check current program status
South Carolina historically has offered few state-level HVAC incentives, and that's still largely true — but two federally funded programs are in development. The SC Energy Office is preparing the Home Efficiency Rebates (HOMES) and Home Electrification and Appliance Rebates (HEAR) programs, funded by the federal Inflation Reduction Act, with anticipated availability in 2026. HEAR is expected to cover electric heat pumps and heat pump water heaters, with larger rebates for low- and moderate-income households; HOMES rebates for whole-home efficiency work are listed by the state at $2,000 to $16,000 depending on income and verified energy savings.
As of July 2026 the rebates are not yet available and applications are not open. Check the SC Energy Office rebates page for launch updates and eligibility rules before counting on these programs in a project budget.

Dominion Energy South Carolina Heating & Cooling Rebates (EnergyWise)
Dominion Energy South Carolina
Active as of July 2026 — confirm current amounts and terms
Dominion Energy South Carolina offers rebates to its residential electric customers for ENERGY STAR qualified equipment in existing homes: published program materials list rebates of up to $500 for qualifying central air conditioners and heat pumps, $650 for replacing an electric furnace with an ENERGY STAR heat pump, $300 for duct sealing or duct insulation, and $750 for an ENERGY STAR certified heat pump water heater. Amounts and tiers can change, so confirm current figures on Dominion's site before purchase.
Equipment must be installed by a licensed mechanical contractor, and the rebate application with a detailed invoice must be submitted within 90 days of installation. Dominion's program does not allow fuel switching for the heat pump/AC rebates — the new unit must be the same equipment type as the one it replaces.
-
Santee Cooper Smart Energy Existing Homes Rebate Program (EmpowerHome)
Santee Cooper
Active for the 2026 program year (December 1, 2025 – November 30, 2026) — confirm current terms
Santee Cooper's Smart Energy Existing Homes program pays rebates to its residential customers for high-efficiency heat pump installations, including split, packaged, and mini-split systems that meet minimum SEER2 and HSPF2 efficiency requirements. Rebate amounts vary by equipment type, efficiency tier, and system size, and the home generally must be at least five years old.
Installations must be performed by a Santee Cooper Trade Ally — a contractor approved under the program — and applications must be submitted within the program year. Santee Cooper serves parts of the greater Charleston area, including some Berkeley County communities.
-
Berkeley Electric Cooperative Dual Fuel & Efficiency Programs
Berkeley Electric Cooperative
Active as of July 2026 — confirm current terms with the co-op
Berkeley Electric Cooperative — which serves areas including Johns Island, Daniel Island, Goose Creek, and Moncks Corner — offers up to a $1,000 rebate for members installing a new dual-fuel heating system (a heat pump with gas backup) when switching from gas heat, and a $500 rebate when switching from an existing heat pump to a dual-fuel system, limited to one rebate per home.
The co-op also offers a smart thermostat program with bill credits and a HomeAdvantage loan program with a 5% interest rate on qualifying energy improvements up to $20,000 — including heat pump, dual-fuel, and mini-split upgrades — with payments added to the electric bill.

Daikin Manufacturer Rebates & Instant Rebates
Daikin (manufacturer)
Rotating promotions — offers vary by location and time of year; check current offers
Daikin runs manufacturer rebate promotions on qualifying systems — such as Daikin FIT complete systems and ductless equipment — installed by a participating independent Daikin Comfort Pro. These promotions rotate through the year, vary by location and equipment combination, and are subject to change at Daikin's discretion, so no specific dollar amount is durable enough to publish here.
Because Holy City Heating & Air is a Daikin Comfort Pro dealer, we can tell you exactly which Daikin promotion, if any, applies to the system you're considering at the time you're buying. Daikin's rebate pages also include a search tool for utility incentives available in your ZIP code.
As a Daikin Comfort Pro dealer, we quote heat pump systems that meet the efficiency tiers utilities actually pay rebates on — not just the minimum code equipment. We'll identify which utility serves your address, point you to the right rebate application and current terms, and structure the remaining balance with Goodleap financing if you want to spread out the cost.
Air Conditioners
Sometimes. Dominion Energy South Carolina lists rebates for qualifying ENERGY STAR central air conditioners in existing homes, and Daikin's rotating manufacturer promotions can apply to qualifying complete systems. The federal 25C tax credit that once covered high-efficiency ACs ended for installations completed after December 31, 2025, so utility and manufacturer offers are the main path now.

Before you commit to a straight AC replacement, we'll compare it against a heat pump — in Charleston's climate a heat pump often costs little more, cools identically, and qualifies for more rebate programs. Either way, we'll walk you through which current utility and Daikin offers your chosen equipment fits and what documentation the program requires.
Furnaces & Heating
Rarely as a standalone purchase, but replacing electric-resistance heat opens real options. Dominion Energy South Carolina pays a rebate for replacing an electric furnace with an ENERGY STAR heat pump, and Berkeley Electric Cooperative offers up to $1,000 for qualifying dual-fuel systems that pair a heat pump with gas backup heat. A like-for-like gas furnace swap has little rebate support in this market in 2026.

If your heating bill is high because of old electric-resistance heat, that's exactly the situation these programs were built for. We'll walk you through the heat pump and dual-fuel options that qualify with your specific utility, explain the trade-offs honestly, and help you line up the program paperwork requirements before installation day so nothing disqualifies the rebate.
Water Heaters
Yes, if you choose a heat pump water heater. Dominion Energy South Carolina lists a rebate for installing an ENERGY STAR certified heat pump water heater, and heat pump water heaters are also on the equipment list for South Carolina's pending HEAR rebate program. Standard tank replacements generally don't qualify for rebates in the Charleston market.

Amounts and tiers can change, so confirm current figures on Dominion's site before purchase.
Equipment must be installed by a licensed mechanical contractor, and the rebate application with a detailed invoice must be submitted within 90 days of installation. Dominion's program does not allow fuel switching for the heat pump/AC rebates — the new unit must be the same equipment type as the one it replaces.
We'll size a heat pump water heater for your household, confirm the model meets the ENERGY STAR certification your utility's program requires, and walk you through the rebate application steps and deadlines — most utility programs require a licensed contractor's detailed invoice submitted within a set window after installation.
Indoor Air Quality
Not usually as a direct rebate. Utility programs in the Charleston area focus on heating, cooling, and water heating equipment rather than air purifiers, dehumidifiers, or filtration. That said, Daikin's rotating promotions occasionally bundle indoor air quality equipment with system purchases, and duct sealing — which directly affects air quality — does carry a Dominion Energy South Carolina rebate.

We'll be straight with you: most IAQ equipment is a comfort and health investment, not a rebate play. Where savings do exist — duct sealing rebates, or a Daikin promotion that includes IAQ add-ons with a system purchase — we'll point them out, and Goodleap financing can cover IAQ work bundled into a larger project.
Maintenance & Tune-Ups
Routine tune-ups themselves aren't rebated, but related improvements are. Dominion Energy South Carolina pays rebates for duct sealing and duct insulation in existing homes, and Berkeley Electric Cooperative offers smart thermostat bill credits and a low-interest HomeAdvantage loan for whole-home efficiency improvements including ductwork and insulation.

During a maintenance visit we can flag rebate-eligible issues — leaky ductwork is the most common one in Charleston homes. If we find a problem worth fixing, we'll explain which utility program applies, what testing or documentation it requires (Dominion, for example, requires before-and-after duct leakage testing for its sealing rebate), and let you decide with the numbers in front of you.
Incentives reduce what you finance — pair them with Goodleap financing and our typical pricing ranges to see the whole picture, or browse the Daikin catalog these programs most often apply to.
Rebate questions, answered straight
Is the federal tax credit for heat pumps still available in 2026?
No. The 25C Energy Efficient Home Improvement Credit was terminated by federal legislation signed in July 2025, and per the IRS it does not apply to any equipment placed in service after December 31, 2025. If your system was installed by that date, you can still claim it on your 2025 tax return using Form 5695 — but 2026 installations do not qualify.
Does South Carolina have a state rebate for HVAC or heat pumps?
Historically, South Carolina has offered very little at the state level for HVAC, and as of July 2026 that's still mostly the case. The SC Energy Office is developing the federally funded HOMES and HEAR rebate programs, which are expected to launch during 2026 and will cover heat pumps and heat pump water heaters with income-based rebate amounts — but applications are not yet open. Check energy.sc.gov/rebates for the current status.
Which utility rebate applies to my Charleston-area home?
It depends on who bills your electricity. Dominion Energy South Carolina customers can use the EnergyWise heating and cooling rebates; Berkeley Electric Cooperative members — common on Johns Island, Daniel Island, and in Goose Creek and Moncks Corner — have the dual-fuel rebate and HomeAdvantage loan; and Santee Cooper customers have the Smart Energy Existing Homes heat pump rebates. We can confirm your utility from your service address before quoting equipment.
Can I stack a utility rebate with a Daikin rebate and financing?
Often, yes. Utility rebates come from your electric provider, Daikin instant rebates come from the manufacturer, and Goodleap financing is a payment method rather than an incentive — so the three generally don't conflict. Each program has its own equipment and paperwork requirements, though, so we'll confirm your specific system qualifies for each one before you sign anything.
Do rebates apply to repairs or maintenance visits?
Not to the visit itself. Rebates in this market attach to equipment and improvements — a qualifying heat pump, a heat pump water heater, or duct sealing and insulation work. Dominion Energy South Carolina's ductwork rebate is the most maintenance-adjacent program, and it requires a licensed contractor plus before-and-after duct leakage testing.
What paperwork do utility rebates require?
The common pattern across Charleston-area programs: installation by a licensed contractor (Santee Cooper additionally requires an approved Trade Ally), a detailed installation invoice, and an application submitted within a deadline — Dominion Energy South Carolina, for example, requires submission within 90 days of installation. We'll walk you through what your utility's program needs so a missed document doesn't cost you the rebate.
Are the rebate amounts on this page guaranteed?
No — every program on this page is controlled by its provider and subject to change without notice, and figures shown reflect what providers published as of July 2026. Always confirm current amounts and eligibility rules on the official program page linked in each listing, or ask us to check the current terms when we quote your project.
