Commercial HVAC Service
Restaurants. Retail. Property Managers.
Salaried technicians. Documented records. Priority response. MD Air serves Northshore businesses the same way we’ve served families — with employees who show up, every time.
About This Service
MD Air and Heat provides commercial HVAC service to restaurants, retail businesses, medical offices, and property managers throughout Northshore and Southshore Louisiana. Unlike residential contractors who “also do commercial,” MD Air’s team is experienced with rooftop units, multi-zone systems, and the high-demand operating environments of food service and commercial buildings. All commercial work is performed by salaried MD Air employees — meaning consistent service, documented records, and a team that shows up the same way every time. For priority commercial service, call 985-649-5379.
Who We Serve
Commercial HVAC Built for
How Your Business Actually Runs
Commercial HVAC isn’t residential HVAC with a bigger price tag. MD Air’s team knows rooftop units, multi-zone systems, and the demands of businesses that can’t afford a down day.
Restaurants & Food Service
Commercial kitchens destroy HVAC equipment faster than any other environment — grease, heat load, and 16-hour operating days. When your exhaust fails on a Friday night, MD Air responds. We service makeup air units, rooftop systems, and kitchen exhaust on Northshore and Southshore properties.
Retail & Strip Mall
A dead rooftop unit on a Saturday in July closes your store. MD Air serves retail tenants and landlords across Northshore corridors — single units or multi-tenant portfolios. One contractor, documented service records, priority scheduling.
Property Managers & Landlords
When a tenant texts at 9pm that the AC is out, you need a company that actually picks up. MD Air’s commercial accounts get priority scheduling, consistent salaried technicians, and full documentation so your property records stay clean.
Commercial emergency? We pick up 24/7.
📞 985-649-5379Medical & Dental Offices
HVAC downtime in a clinical setting is a compliance issue, not just a comfort issue. MD Air serves independent medical and dental practices with documented service records, IAQ upgrades, and technicians who understand the standard.
Rooftop Units & Multi-Zone Systems
RTUs, packaged units, and multi-zone commercial systems require a different skill set than residential split systems. MD Air’s technicians are experienced with commercial equipment — not learning on your building’s dime.
Commercial Maintenance Agreements
A documented maintenance schedule protects your equipment, your warranty, and your bottom line. MD Air offers commercial service agreements with scheduled tune-ups, priority emergency response, and written records after every visit.

📞 985-649-5379Why Commercial Accounts Choose MD Air
Not a Residential Company
That “Also Does Commercial.”
Any contractor can say they handle commercial work. What matters is who shows up, how consistently, and what record they leave behind. Here’s why MD Air earns commercial accounts — and keeps them.
Salaried W-2 Technicians — Consistent Every Visit
Commercial accounts can’t afford a different face every service call. Every MD Air tech is a salaried W-2 employee — trained the same way, held to the same standard, and accountable to this company. No dispatch-board subs who don’t know your system’s service history.
Documented Records After Every Visit
Every commercial service call ends with a written report of findings — what was inspected, what was done, and what to watch. That paper trail protects your equipment warranty, satisfies health inspectors, and gives your property manager documentation that holds up.
Priority Response & 24/7 Emergency
Commercial accounts get priority scheduling — not the same queue as residential calls. For emergencies, real people answer our phones 24/7 and dispatch the nearest available tech. When your dining room hits 85° at 6pm, you don’t have time for a voicemail.
Real Commercial Equipment Experience
Rooftop units, packaged systems, multi-zone commercial installs, makeup air units, exhaust systems — MD Air’s technicians are trained on commercial-grade equipment, not residential splits scaled up. We’re not guessing. We’ve been doing this since 1984.
Background-Checked. Every Tech. Always.
Every MD Air technician passes a full background check before joining the company. When an MD Air tech walks into your restaurant, your retail location, or your medical office, you know exactly who they are — and so do we.
NATE-Certified · Trane & Mitsubishi Authorized
NATE certification is the highest independent standard in the HVAC industry. As authorized Trane and Mitsubishi dealers, our techs receive factory-level training on the equipment they install and service — residential or commercial.
Commercial customers need to know the same person is showing up every time — someone who knows their system, keeps records, and doesn’t disappear between calls. That’s what a salaried team delivers. That’s always been the MD Air way.
