Dallas rows are ConsumerAffairs' published local ranges; the last row is national.

Do this now: AC or heat out in Dallas

1. Check the thermostat setting and batteries, the filter, and the breakers for the indoor and outdoor units. If a breaker trips again, leave it off.
2. Over 90 F inside? The CDC says a fan can raise body temperature at those temperatures; get to air conditioning.
3. Call 911 for heat stroke signs: body temperature above 103 F, hot red dry skin, a fast strong pulse or confusion (Ready.gov).
4. Gas smell near the furnace or a CO alarm? Get out, then call 911 and Atmos Energy from outside.
5. Whole street dark? Report it to Oncor at 888-313-4747 before booking AC service.

Is it an emergency? Dallas heat and freeze

No AC in a Dallas heat wave, or no heat in a freeze, is an emergency when someone in the house is elderly, sick or very young. DFW Airport, the station for both Dallas and Fort Worth, averages 20.2 days a year at or above 100 F and 29.2 nights at or below 32 F, the National Weather Service lists. After hours, HomeAdvisor puts labor at $160 to $250 an hour nationally against $75 to $150 in business hours. See emergency AC repair in Dallas for heat steps and renters' rights.

Dallas mechanical permits and licenses

ConsumerAffairs says full replacements, new ductwork and HVAC-related electrical work in Dallas need a mechanical permit from the city's Building Inspection division. Dallas has adopted the 2021 International Mechanical Code with local amendments (Chapter 55); the Chief Plumbing and Mechanical Inspector is at 214-948-4464. The city's Mechanical Permit Without License checklist (revised July 2000) lets a residential owner do mechanical work without a TDLR license only on an owner-occupied homestead whose exemption is "granted and recorded by the Appraisal District"; incomplete applications are denied if not fixed within five working days.

Everyone else needs a TDLR-licensed air conditioning and refrigeration contractor. TDLR says state law bars cities from charging registration fees to TDLR-licensed contractors, but cities still charge permit fees. Look the license up on TDLR's ACR search.

Air moving but not cold? Check the filter and the outdoor unit first, then see AC not cooling. National part prices are on AC repair cost.

Furnace repair in Dallas: costs, and why Atmos rebates do not apply

Furnace repair in Dallas costs $133 to $505 for most jobs, HomeAdvisor's 2026 national range, with a $318 average; ConsumerAffairs puts a Dallas ignitor or flame sensor at $100 to $300. HomeAdvisor says furnaces last 15 to 30 years, and to start shopping when a repair passes half the price of a new one. If you replace a gas furnace inside Dallas city limits, Atmos's $300 to $350 furnace rebate does not apply; it covers North and Central Texas excluding the City of Dallas.

A gas smell or CO alarm means leave first and call 911 from outside. CPSC names home heating among the top sources of non-vehicle carbon monoxide deaths. See furnace repair and furnace replacement cost.

AC and heat pump installation in Dallas: $7,000 to $15,000 for a full system

AC installation in Dallas runs $7,000 to $15,000 for a full system with a furnace or heat pump, ConsumerAffairs reported in April 2026. Nationally, HomeAdvisor puts a new AC at $5,978 on average ($3,887 to $8,073) and heat pump installation at $6,087 ($4,236 to $7,942). For mini split installation, HomeGuide lists $2,500 to $6,000 for one zone and up to $15,000 or more for a multi-zone system.

Texas is in DOE's Southeast region, where a new split AC under 45,000 Btu/h must be rated at least 14.3 SEER2. No federal tax credit applies in 2026: the IRS says 25C does not cover property placed in service after December 31, 2025. Ask about Oncor's Home Energy Efficiency Program before you sign, and see heat pump installation cost, mini split installation and AC replacement cost.
