Happy Father’s Day from LOUMIS Air

In our industry, we know a thing or two about keeping things running smoothly.

Dads do the same.

Whether they're leading a crew, supporting their families, or making sure everyone is taken care of, fathers are often the steady force that keeps everything moving forward.

Today, we celebrate the men who work hard, lead by example, and help create comfortable spaces for the people who matter most.

You Have a Backup Generator. But Is Your HVAC Ready?

When severe weather threatens, many businesses rely on backup generators to keep operations running. But here's something many facility managers don't realize:

A generator doesn't automatically mean your HVAC system is protected.
Large rooftop units, chillers, air handlers, and other commercial HVAC equipment often require significant po

Even if your building has power, HVAC equipment can still be affected by:
• Power surges and voltage fluctuations
• Improper shutdowns during outages
• Damaged controls and electronics
• Startup issues after extended downtime

Before storm season is in full swing, ask yourself:
✅ Which HVAC equipment is connected to backup power?
✅ Can your generator handle the startup load?
✅ Do you have a restart plan if power is lost?
✅ When was your system last inspected?

The businesses that recover fastest after a storm are the ones that plan before the weather arrives.

LOUMIS Air helps commercial and industrial facilities throughout Louisiana and the Gulf Coast prepare for storm season, minimize downtime, and protect critical HVAC equipment.

Another Critical HVAC Upgrade Completed by LOUMIS Air

Our team recently replaced leaking chilled water and heating water coils in a rooftop air handling unit at Slidell Memorial East. This project required careful planning, crane coordination, and experienced technicians to safely remove the old coils and install new equipment with minimal disruption to facility operations.

When chilled water or heating water coils begin to leak, it can lead to reduced system efficiency, higher operating costs, water damage, poor temperature control, and unexpected downtime. Replacing these components helps restore performance, improve reliability, and extend the life of the HVAC system.

At LOUMIS Air, we specialize in complex commercial and industrial HVAC projects including hospitals and healthcare facilities to manufacturing plants, marine applications, office buildings, and institutional facilities. When your operation depends on dependable climate control, experience matters.
