Step 3: Apply for TDLR Journeyman License

About This Market
Corpus Christi's HVAC market runs hot—literally and figuratively. You've got 8,320 licensed HVAC shops across Texas, and a solid chunk operate in or service the Coastal Bend. Demand here stays strong year-round because of the climate: scorching summers, mild winters, and salt air that corrodes systems faster than inland markets. Residential AC replacement is the bread and butter—most units hit 12-15 years and fail in July when every other contractor is slammed. Commercial work exists (small office buildings, light industrial, hospitality), but residential dominates. Costs trend higher than inland Texas due to labor competition during peak season and material logistics to the coast. A median HVAC tech in Texas earns $28.43/hour ($59,134/year), but Corpus Christi contractors often pay 5-10% above state average to retain talent and fill emergency calls. Competition is real but manageable—it's not Houston or Dallas density, and reputation + response time matter more than rock-bottom pricing.

What's the busiest season for HVAC work in Corpus Christi?
June through August is peak—extreme heat and high humidity overload systems, and every residential and commercial unit that's on its last leg fails in summer.
