WORKING CONDITIONS AND REQUIREMENTS

Climate Control Mechanics work in a variety of places and situations. They may work on ground floors, on roof tops, in customers' homes, or in office buildings. They usually are required to lift heavy objects as well as stoop, crawl, or crouch when making installations.

Some of the hazards of the trade are burns, falls, and electric shocks, falls, exposure to refrigerants, and the dangers that come from lifting heavy objects.

In Michigan, the average workweek for Climate Control Mechanics is 40 hours, usually from 8 A.M. to 5 P.M. Overtime is common during busy seasons and when equipment breaks down. Mechanics who work on both heating and air-conditioning units can be more sure of steady work than those who specialize in only one area.

Although most Climate Control Mechanics work in open (non-union) shops, many Mechanics join either The Plumbers and Pipefitters Union or The Sheet Metal Workers Union. To become members, workers must pass an examination requiring knowledge gained from about five years of work experience. Union members must pay dues.

You Should Prefer:

• Activities involving the use of equipment, processes, or methods

• Activities which bring satisfaction from working on/producing things

You Should Be Able To:

• Look at drawings/pictures/visualize how they would look as objects

• Work within precise limits or standards of accuracy

• Perform a variety of duties which may often change

• Rate information using measurable standards

Math Problem You Should Be Able to Solve:

The speed of a centrifugal compressor is changed from 1,000 to 3,000 rpm. If the compressor originally delivered 2,000 cfm, what will the new delivery be?

Reading Example You Should Be Able to Read and Comprehend:

In the conduction and convection mechanisms, the transfer of heat is associated with matter. For radiant heat transfer, however, a change in energy form takes place, from internal energy at the source to electromagnetic energy for transmission then back to internal energy at the receiver.

Writing Example You Should Be Able to Produce:

Prepare a written estimate for a heating unit installation for a potential customer.

Thinking Skill You Should Be Able to Demonstrate:

Should be able to demonstrate analytical skills and be detail oriented in installing, maintaining, and repairing climate control equipment.

To qualify as a Climate Control Mechanic, a person may become certified through a postsecondary program or complete a 4-year apprenticeship program. Self-employed Mechanics must obtain a mechanical contractor license from the State of Michigan. A local license may be required or may be an asset.
