Apprentice HVAC Installer FAQ
What does an HVAC apprentice installer do day to day in Oklahoma City?
I have my apprentices riding with a lead installer on real jobs from day one. You’ll be carrying equipment, running line sets and low voltage wire, setting condensers on pads, brazing copper, pulling vacuums, and learning duct fabrication and sealing. Mornings start at the shop in Kingfisher around 7:30, then the crew rolls out to the job. You learn by doing, with me or a lead installer watching every cut and every connection.
How much does an HVAC apprentice make in Oklahoma City?
I start apprentices at $18 an hour, with raises as your hours add up. The apprenticeship is a 3-year, time-based program, and when you complete it you are at journeyman pay, $30 an hour. Overtime is paid at time and a half, and I pay weekly. Full benefits kick in at 90 days.
How long is an HVAC apprenticeship before you become a journeyman?
My apprenticeship is a 3-year, time-based program, so plan on 3 years to journeyman. Oklahoma requires 3 years of documented HVAC field work plus the journeyman exam to get the state license. I sign off on your hours every quarter so your paperwork stays clean.
What schooling do I need to apply for an HVAC apprentice job?
A high school diploma or GED is the floor. I prefer applicants who went through Autry Technology Center in Enid or an OSU vo-tech HVAC program, because they already know refrigeration basics and tool safety. If you didn’t go that route, I still want to talk. Show up, be teachable, hold a clean driver’s license, and pass a drug test. I’ll teach the rest.
