HVAC Rebates and Energy Efficiency Programs in Texas
Replacing an HVAC system in Denton is a major investment — typically $6,000 to $15,000 depending on the system. But between federal tax credits, utility rebates, and manufacturer incentives, Denton homeowners can knock $2,000 to $5,000 off that cost in 2026 if they know where to look.
Here’s what’s actually available right now and how to claim it.
Federal Tax Credits (25C)
The Inflation Reduction Act extended and expanded residential energy tax credits through 2032. For HVAC equipment installed in 2026, you can claim:
| Equipment | Credit | Annual Cap | Minimum Efficiency |
|---|---|---|---|
| Heat pump (ducted or ductless) | 30% of cost | $2,000 | CEE Tier 1 (SEER2 16+, HSPF2 9+) |
| Central air conditioner | 30% of cost | $600 | SEER2 16+ |
| Gas furnace | 30% of cost | $600 | 97% AFUE |
| Boiler | 30% of cost | $600 | 95% AFUE |
| Insulation and air sealing | 30% of cost | $1,200 | Meets IECC standards |
| Home energy audit | 30% of cost | $150 | Qualified auditor |
Key details:
- These are tax credits, not deductions — they reduce your tax bill dollar-for-dollar
- The $2,000 heat pump cap is separate from the $1,200 cap on other improvements, so you can claim both in the same year
- Credits reset every year, meaning you can spread upgrades across multiple years to maximize savings
- File IRS Form 5695 with your tax return
Texas Utility Rebates
Your electric provider may offer additional rebates on top of the federal credit. The two most common in Denton:
CoServ Electric (serves most of unincorporated Denton County, Lantana, Argyle, Corinth)
- Up to $500 for qualifying ENERGY STAR heat pumps and central AC
- Rebates for smart thermostats ($50–$75)
- Apply within 90 days of installation with proof of purchase and AHRI certificate
Denton Municipal Electric (DME) (serves City of Denton proper)
- Seasonal rebate programs for high-efficiency HVAC — amounts vary by year
- Free home energy assessments for Denton residents
- Contact DME at (940) 349-8700 or visit denton-energy.com for current offers
Oncor (if your area is in Oncor territory)
- Residential rebates for qualifying AC and heat pump installations
- Smart thermostat rebates
- Check oncor.com/rebates for current programs
How the Savings Stack Up
Here’s a realistic example for a Denton homeowner replacing a 15-year-old 10-SEER system with a new 17-SEER2 heat pump:
| Item | Amount |
|---|---|
| New heat pump system (installed) | $10,500 |
| Federal 25C tax credit (30%, capped at $2,000) | -$2,000 |
| CoServ rebate | -$500 |
| Net cost after incentives | $8,000 |
| Estimated annual energy savings | $400–$700 |
That’s $2,500 back in your pocket on day one, plus lower bills every month going forward.

The efficiency ratings that matter for rebate qualification:
- SEER2 (cooling efficiency) — Minimum 16 SEER2 for federal credit. Most new systems range from 15 to 22 SEER2.
- HSPF2 (heat pump heating efficiency) — Minimum 9 HSPF2 for the $2,000 heat pump credit
- AFUE (furnace efficiency) — 97%+ for the $600 furnace credit. Standard new furnaces are 80% or 96%.
For Denton’s climate, a 17–18 SEER2 heat pump hits the sweet spot between upfront cost and long-term savings. Going above 20 SEER2 adds significant cost with diminishing returns unless your home is large or your ductwork is in the attic (where Denton’s 150-degree summer attic temps eat into efficiency).
Denton-Specific Considerations
- Attic ductwork — Most Denton homes have ducts in the attic, which can lose 20–30% of conditioned air. Sealing and insulating ducts is eligible for the $1,200 insulation credit and often delivers a better return than upgrading the equipment alone.
- Two-stage and variable-speed systems handle Denton’s wide temperature swings (30 degrees in winter to 105 in summer) far better than single-stage units. They also dehumidify more effectively during our humid spring months.
- Permit required — The City of Denton requires a mechanical permit for HVAC replacement. Your installer should handle this. If they suggest skipping it, find a different installer.
Bottom Line
Between the 25C tax credit, utility rebates, and energy savings, 2026 is one of the best years to upgrade your HVAC system in Denton. A qualifying heat pump can save you $2,500+ in incentives upfront and $400–$700 per year in energy costs. Just make sure your installer files the right paperwork and your equipment meets the minimum efficiency thresholds.
Frequently Asked Questions
What HVAC tax credits are available in Texas for 2026?
The federal 25C Energy Efficient Home Improvement Credit covers 30% of qualified HVAC equipment costs, up to $2,000 per year for heat pumps and $600 for central AC or furnaces. This credit resets annually, so you can claim it every year you make qualifying upgrades.
Does CoServ or Denton Municipal Electric offer HVAC rebates?
Yes. CoServ offers rebates up to $500 for qualifying high-efficiency AC and heat pump installations. Denton Municipal Electric (DME) runs seasonal rebate programs — check denton-energy.com or call DME at (940) 349-8700 for current offers.
Is a heat pump worth it in North Texas?
For most Denton homes, yes. Modern heat pumps with variable-speed compressors handle North Texas winters efficiently down to about 25 degrees. Below that, auxiliary heat strips kick in. Given Denton's mild winters, a heat pump typically reduces combined heating and cooling costs by 20–30% versus a traditional AC + gas furnace setup.
How do HVAC installation costs in Denton, TX compare to the wider North Texas region?
HVAC installation costs in Denton are generally competitive with the wider North Texas region, typically ranging from $6,000 to $15,000 depending on the system type and home size. While some larger metro areas might see slightly higher averages, Denton's market is influenced by local labor costs and the specific equipment chosen. Factors like ductwork modifications and system efficiency significantly impact the final price.
What is the ideal time to replace an HVAC system in Denton, Texas to maximize rebates and avoid peak season rush?
The ideal time to replace an HVAC system in Denton is typically during the fall or early spring, before the extreme summer heat or winter cold sets in. This allows contractors to have more flexible scheduling, potentially offering better rates, and ensures your home is prepared for Texas's demanding weather. Federal tax credits are available year-round, but utility rebates from DME or CoServ might have specific application windows, so it's wise to check current programs.
Does the City of Denton, TX require permits for HVAC system replacements?
Yes, the City of Denton requires permits for most major HVAC system replacements and new installations to ensure compliance with local building codes and safety standards. Your licensed HVAC contractor is responsible for obtaining the necessary permits before starting work, which typically involves a plan review and inspections. This process helps ensure the system is installed correctly and safely for your Denton home.
Can Denton homeowners claim federal HVAC tax credits if they do a DIY installation?
No, most federal HVAC tax credits, including the 25C credit, generally require the equipment to be installed by a qualified contractor. The IRS specifies that the installation must meet specific energy efficiency standards and be certified. DIY installations typically do not qualify for these significant financial incentives due to warranty, safety, and certification requirements.
What are the most energy-efficient HVAC options for homes in Denton County dealing with extreme Texas summers?
For homes in Denton County, variable-speed heat pumps and high-SEER2 central air conditioning systems are among the most energy-efficient options for tackling extreme Texas summers. These systems can precisely adjust cooling output to maintain comfort, significantly reducing energy consumption compared to older, single-speed units. Pairing them with smart thermostats and good insulation further maximizes efficiency and savings.
