Explanation:

Question 12

Mechanical contractors specialize in installing mechanical systems like HVAC/R in buildings. Manufacturers make the equipment, general contractors oversee overall construction, and distributors supply products. So a mechanical contractor is most likely to install HVAC/R during office building construction.

Air and water balance specialists work on systems in commercial/industrial settings (like large buildings) to ensure proper air and water flow. Product distributors, manufacturing, and residential environments don't typically need such specialists as much as commercial/industrial.

Releasing refrigerants to the atmosphere is prohibited by federal law (e.g., Clean Air Act) due to environmental harm (ozone depletion, greenhouse effect). Recycling or reclaiming doesn't allow release, and it's not just some states—it's federal.

Answer:

a) Mechanical contractor
