What Most AC & HVAC Job Listings Don't Tell You
General overview for this role type; specifics vary by employer.
HVAC in Texas requires a state license at the company level, and technicians who handle refrigerant need EPA Section 608 certification. Many shops also want NATE certification for higher pay. You can start as an installer helper or entry technician and grow into diagnostics and system design. Pay is often hourly with strong overtime in summer, and service techs frequently earn commission or spiffs on repairs and system sales.
Seasonality drives this trade in Houston. Summer is brutal and busy, with long days, attic heat, and heavy on-call rotations when systems fail. Winter shifts toward heating checks, maintenance plans, and install backlog. New hires underestimate the physical toll of attic and rooftop work in extreme heat. You drive a stocked truck, carry gauges and recovery gear, and stay ready for after-hours emergencies. Steady demand and a shortage of skilled techs keep the field open to anyone who shows up and learns fast.
What to Expect Day-to-Day
General overview for this role type; specifics vary by employer.
A service tech starts with a dispatch list and a truck loaded with common parts. You roll to no-cool calls, check the thermostat, measure refrigerant pressures, test the compressor and capacitor, and inspect the coil and blower. You explain the fault, quote the fix, and get approval before the repair.
Maintenance visits fill much of the shoulder seasons. You clean coils, change filters, flush drain lines, and check amperage so a system does not fail in the next heat wave. Install crews spend the day setting condensers and air handlers, running line sets and ductwork, and brazing connections. Customer trust matters because many repairs are invisible to the homeowner. You document readings, photograph the work, and close the ticket in the field. Expect heat, ladders, tight attics, and a lot of driving between calls, balanced by the satisfaction of restoring cool air on a hundred degree day.

Becoming a Licensed HVAC Technician in Texas

Summer overtime is common while you climb.
