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 every 90 days as skills check out. 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.

How do I apply for an HVAC apprentice job with Hartzell’s Heat and Air?

Call or text me at 405-375-4822, or fill out the application on this page. I read every one myself. If your background fits, I’ll bring you in for a sit-down at the Kingfisher shop, no suit required. I run a small crew with 4.8 stars and 300+ Google reviews, and I hire slow on purpose. Serious applicants only.

Dave Hartzell owner Hartzells Heat Air Kingfisher Oklahoma

I started working for my dad in electrical and HVAC/R in 1978-79, 47 years in the trade now, including 12 years at a Watonga HVAC company learning the trade from the ground up. I opened Hartzell’s about 15 years ago.

That’s still how I train, on real jobs, with experienced techs, starting with the basics and building up. No shortcuts.
