For example, you may spend a day repairing a furnace, installing a central air conditioning unit, or constructing an air handling system in a newly constructed building.
Education: High school diploma is required. A diploma from a trade school can also be significant. HVAC/R technicians need strong math and reading skills to review and follow instructions and blueprints.

Utility Technician
