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.
