Heating and cooling in Texas

Long cooling seasons with heavy moisture. Air conditioners and heat pumps run most of the year, and humidity control matters as much as temperature.

Texas requires air conditioning and refrigeration contractors to hold a license from the Texas Department of Licensing and Regulation (TDLR). The license number should appear on the contractor's vehicles, invoices and proposals; you can verify it on the TDLR website.

Summer is long. Dallas, Fort Worth, Austin, San Antonio and Houston all see weeks above 100°F or near it, and attic-mounted equipment works hard. Along the Gulf Coast humidity control matters as much as cooling.

Winter storms are rare but severe; the February 2021 freeze showed how fast heat pumps and pipes can be overwhelmed. Most Texas homes use heat pumps or gas furnaces with central AC.

Across Texas, AC sizing should follow a load calculation rather than square footage alone. Attic insulation and duct sealing often do as much for comfort as a bigger unit.

Texas city guides

Local details on housing, utilities and permits.

Dallas, TXDallas summers bring long stretches near or above 100°F, and attic-mounted equipment does most of the work. Winters are usually mild, but ice storms and rare deep freezes can overwhelm heat pumps.Houston, TXHouston's heat and humidity make air conditioning a year-round necessity. Controlling moisture is as important as cooling, and hurricane season adds power outages and flooding to the list of things that can damage equipment.San Antonio, TXSan Antonio has long, hot summers with humidity from the Gulf and mild winters with occasional hard freezes. Most homes rely on central AC with a gas furnace or a heat pump.Austin, TXAustin's summers run hot and long, with many days over 100°F, while winters are mild with occasional freezes. Rapid growth means a mix of older central homes and new construction with modern heat pumps.Fort Worth, TXFort Worth summers bring long runs of 100°F days, spring hail storms are among the most damaging in the country, and winter ice storms test heat pumps. Most homes use central AC with a gas furnace or heat pump.El Paso, TXEl Paso is a high desert city at about 3,700 feet, with hot, dry summers and cool winters. Evaporative coolers are still common, and refrigerated air and heat pumps take over for many homes, especially during the summer monsoon.Corpus Christi, TXCorpus Christi's coastal climate means heat, humidity and salt air nearly year-round, plus hurricane risk from June through November. Air conditioners run most of the year, and coastal corrosion shortens equipment life.Arlington, TXArlington sits between Dallas and Fort Worth and shares the region's long 100°F summers, damaging spring hail and occasional winter ice storms. Most homes are 1970s–2000s builds with attic air handlers and a gas furnace or heat pump.Tyler, TXTyler is in the piney woods of East Texas, where summers are hot and very humid and winters mild. Heat pumps and gas furnaces with central AC are both common, and dense tree cover brings heavy spring pollen.Waco, TXWaco summers bring long runs of 100°F days, and Central Texas storms bring hail and occasional tornadoes. Most homes use central AC with a gas furnace or heat pump.Irving, TXIrving, between Dallas and Fort Worth, shares the metro's long hot summers and damaging spring hail.

Long 100°F summers, North Texas hail and occasional ice storms define the work, and larger two-story homes often have two systems.Lubbock, TXLubbock sits on the High Plains at about 3,200 feet, with hot, dry summers, cold winter snaps, dust storms and hail. Central AC with gas furnaces is standard, and outdoor units take a beating from wind and dust.Beaumont, TXBeaumont, near the Gulf Coast, has long, hot and very humid summers and serious hurricane and flood risk; Hurricane Harvey flooded much of the area in 2017. AC runs most of the year, and dehumidification is as important as cooling.Denton, TXDenton, a college town north of Dallas, has long hot summers, spring hail and occasional ice storms. Its mix of historic homes near the square, student rentals and fast-growing subdivisions keeps HVAC contractors busy.McKinney, TXMcKinney is one of the fastest-growing cities in North Texas, with a historic downtown and large newer subdivisions. Long 100°F summers, spring hail and occasional ice storms define HVAC needs, and many homes have two systems.Frisco, TXFrisco grew from a small town to a large suburb mostly since 2000, so nearly all homes are newer two-story houses, often with two or three systems.
