About HVAC in Killeen
Killeen averages daytime highs of about 96 to 97°F in July and August, so air conditioning runs hard through the summer, while January lows average about 36°F and furnaces and heat pumps still get regular use. 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.
