About HVAC in Tyler
Tyler's 1991-2020 normals at Tyler Pounds Field show average highs of 94 to 95°F in July and August and January lows near 37°F, so homes here need dependable cooling through a long, humid summer and heat on winter nights. 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 27 October 2026.
