Starting Out As An Apprentice

Like most of the trades, the HVAC field is a great area in which to do an apprenticeship. To make sure you’re going through a genuine program with a legitimate master, Oklahoma requires apprentices to register. There’s no testing involved in this. But you and the licensed HVAC contractor you are working with must complete a form.

You need to be at least 14 years old and legally able to work in the United States to undertake this program. There’s a $25 fee for your first card, which is valid for one year. To renew, the fee is $20.

You’ll also need to fill out a page verifying that you are lawfully in the USA. This page has to be notarized, which will cost a few more dollars. You can find the complete form – both the general registration and the affidavit of lawful presence, here.

HVAC/R Journeyman and Contractor Licenses: Work Allowed

HVAC/R licenses in Oklahoma fall under the broad category of “Mechanical” and are issued by Construction Industries Board. There are two primary categories in licensing for HVAC professionals. There are different classifications under each of these general levels.

HVAC Limited Journeyman/Limited Contractor

With this license, you are allowed to work on cooling products, equipment or systems up to 25 tons. For heating products, the limit is 500,000 Btu/h per appliance. You may also work on refrigeration, natural gas piping and sheet metal.

HVAC Unlimited Journeyman/Unlimited

As the name implies, this license doesn’t bind you to the same size restrictions mentioned for the Limited Journeyman license. So it allows you to work on any size heating or cooling unit.

Limited Residential Journeyman

This license is for you if you only intend to work on detached one- or two-family dwellings or townhouse-type dwellings not more than three stories high. They must have “separate means of egress” – in other words, you can’t work on apartment houses or buildings. Here you are allowed to work on cooling systems up to 5 tons or heating systems up to 150,000 Btu/h.

You can also install related accessories, such as clothes dryer ventilation, kitchen vent hoods, or exhaust fans. However, you cannot do welding, soldering or brazing; fuel gas piping, or final electrical connections.

There is no equivalent contractor license for this. You will need to apply as a Limited Contractor if you expect to only do residential work.

Refrigeration Journeyman/Refrigeration Contractor

This license allows you to work on refrigeration systems, equipment or products. Of course, you’ll also need Section 608 certification if you will need to purchase or work with refrigerants. That license is part of federal law through the Environmental protection agency.
