Oncor Rebates for DFW Homeowners
Oncor (the electric delivery company for most of DFW) runs the Take A Load Off Texas program with rebates for energy-efficient HVAC upgrades:
Heat Pump Rebate — $500–$3,500
Highest tier. Ducted and ductless heat pumps meeting efficiency requirements. Exact amount depends on SEER2/HSPF2 ratings. Stackable with the federal $2,000 tax credit.
AC Replacement Rebate — $200–$1,500
For qualifying high-efficiency central AC systems. Higher SEER2 = higher rebate. Stackable with federal $600 AC credit.
Smart Thermostat — $50–$100
For ENERGY STAR certified models. Some retail electric providers (TXU, Reliant) offer additional thermostat incentives that stack.
Federal Tax Credits (separate from Oncor)
Heat pump: up to $2,000. Central AC: up to $600. Gas furnace: up to $600. These are tax credits (not deductions) claimed on IRS Form 5695. They reduce your tax bill dollar-for-dollar.
What Drives HVAC Costs in DFW
Home size
A 1,200 sq ft bungalow in Oak Cliff needs a 2-ton system ($4,500–$7,000). A 3,500 sq ft home in Southlake needs a 5-ton system ($9,000–$16,000). Multi-story homes cost 10–20% more due to longer refrigerant runs and more complex ductwork.
Ductwork condition
Homes built before 1985 in East Dallas, Lakewood and Oak Lawn often have original metal ductwork that's corroded, leaky or undersized. Replacing adds $2,500–$7,000. Homes in newer suburbs (Frisco, McKinney, Prosper — 2005+) typically have modern flex duct in good condition.
Access
Attic air handlers are standard in DFW — but tight attic crawl spaces in older homes (especially pier-and-beam in Lakewood and M-Streets) make installation harder and costlier. Ground-level utility closet or garage installations are 10–15% cheaper on labor.
Time of year
June–August replacements cost 10–20% more. October–February gets you better pricing, faster scheduling and the company's A-team installers. If you know your system is aging, plan a fall replacement.

Get 3 quotes. DFW prices vary 30–50% for the same equipment. We find you one licensed contractor who fits your job and budget.
- 2.
Choose a heat pump. Oncor rebate: $500–$3,500. Federal credit: $2,000. Total potential savings: $2,500–$5,500. A traditional AC gets $200–$2,100 max. The math heavily favors heat pumps.
- 3.
Schedule off-peak. October through February. Better pricing, faster scheduling, more negotiating power.
- 4.
Use 0% financing. Most DFW contractors offer 0% APR for 18–60 months. A $8,000 system at 0% for 60 months = $133/month. Far better than emergency credit card charges.
HVAC Cost Questions — Dallas
Is HVAC more expensive in Dallas or Houston?
Roughly the same. Both metros have millions of people and fierce contractor competition. Dallas runs slightly higher for heating work (more furnaces, colder winters) and slightly lower for AC work (less humidity means fewer moisture-related repairs). The real cost difference is in rebates — Oncor (Dallas) offers $500–$3,500 for heat pumps while CenterPoint (Houston) offers $500–$2,000. For heat pump installations, Dallas homeowners actually come out ahead after incentives.
How can I reduce my electricity bill in Dallas without replacing my system?
Three moves with the best ROI: 1) Seal duct leaks — the average DFW home loses 25–35% of conditioned air through duct gaps, especially in unconditioned attics. Sealing costs $400–$1,200 and saves $200–$400/year. 2) Add attic insulation to R-38 if you're below that. Costs $1,000–$3,000 and cuts cooling costs 15–25%. 3) Switch electricity providers on powertochoose.org — a $0.02/kWh difference on a 1,500 kWh/month bill saves $30/month ($360/year).
Should I repair or replace my Dallas HVAC system?
The 50% rule: if the repair exceeds 50% of a new system AND the unit is over 10 years old, replace it. Any R-22 system should be replaced regardless — R-22 costs $100–$200/lb now. After 12 years in DFW's climate, expect the failure cascade — capacitor goes, then contactor 6 months later, then the compressor a year after that. When you factor Oncor rebates and federal credits, replacement is more affordable than most people expect. A $9,000 heat pump can net to $4,500–$5,500.
Do I need a permit for HVAC work in Dallas?
Yes, for installations and replacements. The City of Dallas requires a mechanical permit, which costs $100–$500 depending on scope. Your licensed contractor handles the application and city inspection scheduling. Repairs (capacitor swap, refrigerant recharge) don't need permits. Fort Worth, Plano, Frisco and other DFW cities have their own permit requirements — your contractor handles whichever jurisdiction you're in. Always verify TDLR ACR license before hiring.
What time of year is cheapest for HVAC replacement in Dallas?
October through February. Summer emergency replacements cost 10–20% more because every HVAC company is slammed and you lose negotiating leverage. Fall and winter installations get better pricing, faster scheduling (3–5 days vs 2–3 weeks) and the HVAC company's best crews (they're not stretched thin with emergency calls). If your system is aging, plan the replacement for October–November when it's cool enough to survive a day or two without AC during installation.
