Choosing a Dallas HVAC Installer
- →
Verify TDLR license. Texas requires all HVAC installers to hold a valid license through the Texas Department of Licensing and Regulation. Check at tdlr.texas.gov.
- →
Demand a Manual J calculation. Any installer who sizes your system by square footage alone is cutting corners. A Manual J accounts for insulation, windows, ductwork condition and sun exposure. Wrong sizing = comfort problems for the next 15 years.
- →
Confirm Oncor enrollment. Not every contractor is enrolled in Oncor's rebate program. Ask before signing. If they're not enrolled, you can't get the rebate — even if the equipment qualifies.
- →
Get 3 quotes minimum. Prices vary 30–50% between DFW companies. We find you one vetted installer who fits — free and no obligation.
- →
Ask about labor warranty. Equipment warranties (5–10 years) come from the manufacturer. Labor warranties come from the installer. A good company backs their work with 1–2 years of labor coverage. Great companies offer 5–10 years. This matters because a warranty claim on a compressor is useless if you have to pay $800 in labor to install it.
HVAC Installation Questions — Dallas
What SEER2 rating should I choose for Dallas?
16–17 SEER2 is the sweet spot for DFW. Going from 15 to 17 SEER2 adds $1,500–$2,500 upfront but saves $200–$400 per year on Oncor electric bills. Payback period: 5–8 years. Above 18 SEER2, the savings per dollar spent drop off unless you're getting significant Oncor rebates. For a 2,500 sq ft Dallas home, a 17 SEER2 system typically costs $7,000–$9,000 installed.
How long does HVAC installation take in Dallas?
Standard like-for-like replacement: 4–8 hours (one day). If you're adding ductwork, upgrading electrical or changing system type (e.g., adding a heat pump), expect 1.5–2 days. Scheduling lead times: 3–7 days off-peak, 2–4 weeks during summer. Pro tip: schedule your replacement in spring or fall for faster availability and occasional off-season discounts.
Should I get a heat pump in Dallas?
Heat pumps are a strong choice for DFW. They cool in summer and heat in winter efficiently. Dallas winters rarely drop below 20°F, which is well within heat pump range. You get the highest Oncor rebates ($500–$3,500) and federal tax credits (up to $2,000). The only downside: heat pumps produce gentler heat than gas furnaces. If you want that blast of hot air, go dual-fuel (heat pump + gas furnace backup).
Does the City of Dallas require a permit for HVAC?
Yes. Dallas building permits for HVAC replacement cost $410–$2,600 depending on project scope. Your contractor handles the permit application and scheduling the city inspection. The inspection happens after installation to verify code compliance. Never hire a contractor who suggests skipping the permit — unpermitted work creates liability issues and can affect home insurance claims and resale.
What Oncor rebates can I stack with federal credits?
You can combine Oncor rebates and federal tax credits. Example: $8,000 heat pump installation. Oncor rebate: -$2,000. Federal tax credit: -$2,000. Net cost: $4,000. That's half off. Add a smart thermostat ($150–$500) and Oncor gives another $50–$150 for that. The key is using a contractor enrolled in Oncor's program — they handle the rebate paperwork for you.
