Frequently asked questions
What does a mechanical engineer do?+
Mechanical engineers design HVAC systems, machinery, thermal and fluid systems, manufacturing equipment, and building MEP. They handle everything that moves, heats, cools, or pressurizes.
Do mechanical engineers need a P.E. license?+
A P.E. is required to seal MEP drawings submitted for building permits and for most public-sector work. Product design and manufacturing roles often don't require licensure.
How are mechanical engineers different from industrial engineers?+
Mechanical engineers design physical systems and equipment. Industrial engineers optimize the processes, layouts, and workflows that use that equipment.
How do I find an HVAC engineer near me?+
Search by state — most jurisdictions require the engineer of record to be licensed in the state where the building sits, even if the firm is elsewhere.
Can I get an estimate before hiring?+
Yes. The AI Estimator generates a rough order-of-magnitude scope and cost in under a minute.
