About HVAC in Waco
Waco averages daytime highs of about 97°F in July and August, so air conditioning works hard through a long summer, while January lows average about 36°F and still call for heat. Texas HVAC contractors are licensed by the Texas Department of Licensing and Regulation (TDLR) as Class A or Class B air conditioning and refrigeration contractors, with license numbers that begin TACLA or TACLB. Ranked by license record and years licensed, never by payment. Checked 27 October 2026.
