AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Possible causes include a failing fan motor, a loose blower wheel, or worn compressor bearings. Turn the system off at the thermostat and call a technician.

Dallas had an estimated 1,329,491 residents on July 1, 2025. In Dallas, the median home was built in 1980 with a current median value of $295,300. Around 42% of homes are owner-occupied. About 33% of households heat with natural gas vs. 65% electric. The Texas grid averages $0.15/kWh.

HVAC in Dallas, TX: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Texas licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Dallas Love Field (KDAL) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00013960), Dallas records an annual mean temperature of 68.0°F, approximately 3,124.8 annual cooling degree days against 1,991.6 heating degree days, 38.32 inches of annual precipitation, and only 1.7 inches of snowfall. The 1.6:1 CDD-to-HDD ratio defines Dallas as a cooling-dominated Zone 3A warm-humid climate. But the region’s defining HVAC risk factor isn’t heat — it’s severe weather: per the NOAA National Weather Service Fort Worth/Dallas Tornado Climatology, North and Central Texas averages 26 tornadoes per year, peaking at 7 per month in both April and May. Outdoor condenser units in the Dallas area benefit from impact-resistant hail guards and proper wind-load tie-downs.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Dallas city, Texas) report 528,038 occupied housing units with a median year built of 1980. Heating-fuel distribution: 65.2% electricity (344,045 units) dominates, with 33.0% utility natural gas (174,386 units). Like Houston, Dallas’s electric-dominant heating reflects the short heating season (1,991 HDD) and widespread heat-pump adoption — systems that serve the far-larger cooling load efficiently and handle the modest winter heating requirement as a secondary function.
Texas Dept. of Licensing & Regulation
Every HVAC contractor in Dallas must hold a current Air Conditioning and Refrigeration (ACR) Contractor license issued by the Texas Department of Licensing and Regulation (TDLR), governed by Texas Administrative Code Title 16 Chapter 75. The two classes are strictly defined: Class A “allows you to work on any size unit”; Class B “allows you to work on cooling systems of 25 tons and under, and heating systems of 1.5 million BTUs/hour and under” (residential and light commercial). Licensure requires “at least 48 months of practical experience in air-conditioning and refrigeration-related work under the supervision of a licensed air conditioning and refrigeration contractor in the past 72 months.” Insurance minimums are also tiered: Class A requires $300,000 per occurrence / $600,000 aggregate; Class B requires $100,000 per occurrence / $200,000 aggregate. For typical Dallas residential work, a Class B contractor is fully qualified and sufficient — Class A matters only for commercial projects above 25 tons.
DSIRE Database (NCSU + DOE)
Dallas electricity distribution is handled by Oncor Electric Delivery (the Transmission and Distribution Utility), but retail electricity service is provided by a Retail Electric Provider (REP) chosen by the consumer under the Texas deregulated market. Oncor itself runs residential energy-efficiency programs, including heating and cooling, under the Take A Load Off, Texas name; they are delivered through participating third-party service providers, and Oncor says most of its programs are available from January to November each year. To compare current rebate dollar amounts, use the ENERGY STAR Rebate Finder (EPA) filtered to your Dallas ZIP, or the DSIRE database for Texas residential incentives. Atmos Energy administers any natural-gas-specific rebates. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21). Permit fees for residential mechanical work are set by the City of Dallas Building Inspection Division; contact Building Inspection at 320 E. Jefferson Blvd, Room 118, for the current mechanical permit fee schedule.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
