About HVAC in McAllen
McAllen's 1991-2020 normals at McAllen Miller International Airport show average highs of about 99°F in July and 100°F in August, with summer nights near 79°F and January lows around 53°F, so air conditioning runs most of the year and heating is needed only on occasional cold fronts. In Texas anyone who installs, repairs or maintains air conditioning, refrigeration or heating systems must hold an Air Conditioning and Refrigeration Contractor license from the Texas Department of Licensing and Regulation (TDLR), issued as Class A or Class B with an environmental air conditioning and/or commercial refrigeration endorsement. Ranked by license record and years licensed, never by payment. Checked 28 October 2026.
