Frequently asked
I specialize in mechanical ventilation solutions for factories and industrial plants. My work includes servicing and installing equipment like industrial exhaust-fan hoists, makeup-air unit service platforms, duct static smoke-test kits, and explosion-proof motor test meters. I focus exclusively on the mechanical systems that keep manufacturing environments safe and properly ventilated.
Yes, I provide a dedicated 24/7 emergency line specifically for urgent no-heat/no-cool calls affecting industrial facilities. While my normal business hours are Monday through Friday from 7am to 5pm, this separate emergency number ensures that critical ventilation problems in your plant or factory are addressed immediately, even outside of regular business hours.
I’ve been operating Orlando Mechanical HVAC, Inc. since 1995, which means I’ve spent over three decades providing mechanical ventilation support to industrial clients throughout the Chicago metropolitan area. That’s 31 years of hands-on experience working with factory environments and their unique mechanical needs.
Absolutely — I regularly work on and test explosion-proof motors using tools such as an explosion-proof motor test meter. My background includes handling complex industrial ventilation challenges, including systems that must meet strict safety codes and environmental standards for hazardous locations in manufacturing facilities.
