Get Paid to Upgrade Your A/C: The 2026 Oncor Incentive Guide for DFW
If your air conditioner is over 10 years old, you are sitting on a potential goldmine.
As of January 14, 2026, the Oncor Home Energy Efficiency (HEE) Program is officially open for the season. As a local Authorized Service Provider for Oncor, Greentech Engineering has analyzed the new 2026 program manual to bring you the exact numbers.
This year, the incentives for upgrading to a high-efficiency system are substantial—reaching as high as $3,400 for larger systems. But be warned: these funds are limited and distributed on a strict first-come, first-served basis.
How Much Can I Save? (2026 Incentive Caps)
Unlike standard manufacturer rebates, Oncor incentives are performance-based. This means the more energy-efficient your new unit is (SEER2/EER2 ratings), the higher your potential payout.
Here are the official 2026 incentive caps per system size:
- 2 Ton: Up to $2,000
- 3 Ton: Up to $2,600
- 4 Ton: Up to $3,200
- 5 Ton: Up to $3,400
Note: These incentives are paid directly to us (the Service Provider) and passed on to you as an instant discount on your invoice. You do not need to mail in a rebate form!
Why We Are Prioritizing Forney & Little Elm This Year
While Greentech Engineering services the entire DFW Metroplex, we are seeing a "Perfect Storm" for eligibility in two specific communities right now.
📍 Forney, TX (Kaufman County)
Forney's massive housing boom between 2005 and 2010 means thousands of homes are now hitting the critical 15-year mark. If you live in neighborhoods like Devonshire or Windmill Farms, your builder-grade unit is likely at the end of its life. Replacing it now with a high-efficiency 4-ton or 5-ton unit often qualifies for the maximum incentive tier.👉 [View our Forney HVAC Service Availability]
📍 Little Elm, TX (Denton County)
The unique humidity from Lake Lewisville puts extra strain on older compressors, leading to early failure in areas like Paloma Creek or Sunset Pointe. Upgrading to a modern variable-speed Heat Pump isn't just about the rebate—it's about humidity control. New SEER2 systems handle our lake climate significantly better than older single-stage models.👉 [View our Little Elm HVAC Service Availability]
Am I Eligible? (The Checklist)
To qualify for the 2026 Oncor HEE Program, you must meet three strict criteria:
- Oncor Service Area: You must receive electricity delivery from Oncor. (This covers most of Dallas, Forney, Little Elm, Plano, and Frisco).
- Retrofit Only: This program is for replacing an existing, working central A/C or Heat Pump.
- Warning: Do not remove your old unit yourself! We are required to take "Before" photos of the unit’s nameplate and installation to prove eligibility.
- Efficiency Standards: Your new system must meet 2026 federal SEER2 standards. For example, a new heat pump must have a minimum SEER2 of 14.3 and HSPF2 of 7.5.
The "Authorized Service Provider" Difference
This is the most critical part: You cannot apply for this program yourself.
Oncor regulations require that all paperwork, load calculations, and eligibility checks be submitted by an Authorized Service Provider like Greentech Engineering. We handle the entire compliance process for you:
- Meter Verification: We verify your eligibility instantly using Oncor's portal.
- Manual J Load Calculation: We ensure your new unit is sized perfectly for your home’s square footage and exposure.
- Inspection: We perform the required QA/QC inspections to ensure your installation meets Oncor’s strict quality standards.
Frequently Asked Questions (FAQ)
Q: Can I replace a broken unit and get the incentive?
A: Yes, but the old unit must still be on-site so we can document it. Do not let anyone haul it away before we arrive!
Q: Is this a tax credit?
A: No, this is a utility incentive that reduces your upfront cost. However, many high-efficiency units also qualify for the federal 25C Tax Credit (up to $2,000), meaning you can potentially stack both savings.
Q: When does the program end?
A: The program officially closes on December 4, 2026, OR when the budget runs out. In previous years, funds have run out by late summer, so we recommend booking your evaluation early in the year.
