Commercial Kitchen Hoods And Exhausts
Not all HVAC companies have the experience or knowledge to service or install a kitchen hood and exhaust system. John has more than 20 years of expertise in kitchen hood design, maintenance, and installation. John not only installs kitchen hoods and exhaust systems, but he also has the skill set to balance the system with the properly sized make-up air unit (MAU). Have you ever had trouble opening a restaurant door, as if it's being held by a vacuum? There's a good chance their MAU is not properly sized to the exhaust fan. Not only does it inconvenience their patrons, but draws conditioned air out of the building. That increases their utility bills!
Do You Need Help With A New Or Current Kitchen Hood and Exhaust System?

Sheet Metal Fabrication Services
John's Mechanical Services has a full sheet metal fabricating shop. They produced ventilation duct from galvanized steel, stainless steel, aluminum, and rolled steel for oil-saturated exhaust fumes. Is an industrial look with spiral duct what you're looking for? John's Mechanical Services can install that too! From fabricating residential supply and return duct, exhaust venting for kitchen exhaust hoods and machine shop fumes, to painted spiral duct fittings and large insulated commercial ductwork, John's can tackle your next fabricated sheet metal needs.
Duct Balancing And Building Analysis Services
Without proper duct balancing, the required amount of air to properly condition the space it's servicing will not be met. Couple that with a leaky building envelope, you'll continue to have energy efficiency troubles. Few HVAC shops have the skill sets to balance their ductwork, let alone have an on-board certified Building Analysis Professional. They'll blame the equipment or the architecture for the issues. John's has those skill sets.
With over 20 years of experience in duct design and balancing, you can trust John's Mechanical Services to transform your plans into a functional ventilation system that meets or exceeds ACCA Manual D and SMACNA Manual D guidelines. Are you ready to ensure your facility is as energy efficient as it can be? Have John perform a comprehensive building analysis. He will provide solutions that meet your needs and budget.
