A poorly maintained HVAC system is more than an inconvenience — it’s a long-term liability. At Calcasieu Mechanical Contractors, we help businesses across Baton Rouge, Lafayette, Lake Charles, New Orleans and Beaumont eliminate that risk with industrial HVAC preventative maintenance service programs designed to reduce breakdowns, control energy costs and extend the lifespan of your system.
Since 1988, we’ve provided Louisiana and Texas facilities with customized maintenance plans and 24/7 commercial HVAC service that puts performance, efficiency and safety first.

No two buildings are the same, and no two HVAC systems should be treated the same either. That’s why our commercial and industrial HVAC maintenance programs are fully customized to the needs, usage patterns and priorities of each client.
We begin every engagement with a building performance assessment, where our team benchmarks your HVAC costs against those of similar facilities, evaluates the current condition of your equipment and identifies potential maintenance gaps. From there, we develop a tailored maintenance strategy that aligns with your capital planning, energy goals and operational schedule.
Whether you manage a high-traffic commercial property or a 24/7 industrial facility, CMC ensures your HVAC system receives the right attention at the right intervals, with service documentation available any time through your dedicated client portal.
Our digital client service portal gives you complete transparency and control over your maintenance program. Through the portal, you can:
Maintenance checklists and records are uploaded in real time, keeping your operations team informed and in compliance with internal and external reporting requirements.
Our commercial HVAC preventative maintenance programs are built around a proactive, data-driven philosophy. Regular maintenance visits include filter replacements, lubrication, system calibrations, refrigerant level checks, safety testing and complete inspections of all moving parts and major components.
The benefits of this approach include:
These cost-saving benefits make HVAC maintenance for commercial and industrial systems one of the smartest operational investments you can make.
With decades of industry experience, CMC helps you think ahead. Our industrial HVAC maintenance plans include capital expense forecasting, helping you anticipate major repairs or system replacements before they become emergencies.
We evaluate lifecycle data, usage patterns, equipment condition and repair history to offer realistic budget recommendations. This insight gives you the ability to plan for large expenses, avoid reactive spending and maintain stable financial control of your facility’s mechanical systems.
Calcasieu Mechanical Contractors is committed to workplace safety and operational excellence. As an ISNetworld and Avetta compliant contractor, we maintain high standards across every aspect of our field and shop work.
Our technicians hold EPA certifications for commercial HVAC service, and we follow documented safety protocols for every inspection, cleaning and service call. Whether performing routine filter changes or inspecting complex packaged systems, we apply the same level of quality control and risk mitigation across all services.
When something does go wrong, there’s no time to waste. Our maintenance clients receive priority access to 24/7 emergency service, with discounted rates and faster response times.
Because our technicians already know your system, they can diagnose and respond to issues faster — minimizing downtime and avoiding unnecessary disruption. It’s one of the many benefits of having a trusted HVAC partner who’s already familiar with your equipment, layout and operational priorities.
As an Entergy Trade Ally, CMC can help you identify and take advantage of available rebate programs, control upgrades and system improvements that reduce your environmental footprint.
Our services help building owners take advantage of energy-saving technologies — including automation, demand-controlled ventilation and smart controls — integrated seamlessly with your commercial HVAC maintenance program.
