Five HVAC Safety Tips for Our Emerald Coast Neighbors

A little friendly advice from your neighbors at Mills Heating & Air

When a storm rolls through the Emerald Coast, we all have the same things on our minds: Is everyone safe? How are our neighbors doing? And where do we even begin with the cleanup?

Once the skies clear and the power starts coming back on, it’s natural to want everything back to normal as quickly as possible.

But before you turn that AC back on, there’s something important we want you to think about: Is your system safe to operate?

Here at Mills Heating & Air, we’re not just HVAC professionals. We’re your neighbors. We live here, work here, raise our families here, and care about the same communities you do.

We’ve seen firsthand what storms can do to heating and cooling equipment, and we want to share a few things we’ve learned along the way.

Whether you call Mills or another trusted HVAC company, we just want you and your family to be safe.

Here are five things worth checking after a storm.

1. Power Restored? Don’t Rush to Restart Your AC!

Power outages and electrical surges are common during severe storms. Power surges can damage important parts of your AC system, even when everything looks fine from the outside. Once power returns, pay attention to how your system operates.

Watch for these warning signs:

• Unusual buzzing, humming, or grinding noises
• Burning or electrical odors
• A system that repeatedly shuts off
• An air conditioner that is not cooling properly

If you notice any of these issues, turn the system off if it is safe to do so and contact a qualified HVAC professional.

A Friendly Reminder from Mills: Avoid repeatedly resetting a tripped breaker. It could be a sign of an electrical problem that needs professional attention.

2. Was Your Outdoor AC Unit Submerged in Floodwater?

Flooding is one of the most serious threats to HVAC equipment during a storm. Even after the water recedes, an outdoor AC unit may have hidden electrical or mechanical damage.

If your HVAC equipment was submerged, DO NOT turn it on—even after the water is gone. Floodwater can damage electrical connections, motors, controls, and other components, and can leave behind contaminants.

Once the area is safe, have a qualified HVAC professional assess the damage and help determine the safest next step.

A Friendly Reminder from Mills: Just because an outdoor unit looks fine does not mean it is safe to operate. Have it inspected after flooding.

3. Look for Visible Storm Damage

High winds, flying debris, and fallen branches can damage outdoor HVAC equipment without anyone noticing right away. Once conditions are safe, take a look around your outdoor unit from a safe distance.

Look for:

• Fallen branches or debris
• Shifted or tilted equipment
• Damaged exterior panels
• Exposed electrical wiring
• Damaged refrigerant lines

Never reach inside the unit or attempt to remove debris caught in the equipment. If something does not look right, leave the system off and contact a qualified technician for professional AC repair.

A Friendly Reminder from Mills: Keep the area around outdoor equipment clear for airflow, but never try to move or straighten a damaged unit yourself.

4. Don’t Forget Your Air Filter!

Storm cleanup can stir up a lot of dust and debris, especially when damaged materials are being removed. Your HVAC filter helps capture airborne particles as air moves through the system.

Once your equipment is safe to operate, check the indoor air filter and replace it if it is dirty or clogged. A clean filter helps your system breathe easier and work the way it should.

A Friendly Reminder from Mills: If your home had indoor flooding or significant water damage, address moisture and possible contamination before operating the HVAC system. A filter change alone may not be enough. The EPA offers helpful guidance on cleaning up a flooded home safely.

5. Business Owners and Property Managers: Check Your Equipment, Too!

Commercial HVAC equipment can take a beating during severe weather. Rooftop units, condensers, and other systems may be affected by wind, flooding, or electrical problems.

From a safe location, look for obvious damage before restarting equipment that may have been affected. If something does not look right, it is worth having a qualified commercial HVAC professional inspect it before turning it back on.

A Friendly Reminder from Mills: Photograph visible storm damage from a safe distance. Those pictures may be helpful when coordinating repairs and insurance claims.

One More Thing: Running on Generator Power?

After a storm, many homes and businesses rely on generators while waiting for regular utility power. The CDC provides important generator safety recommendations to help protect your family from carbon monoxide poisoning. If you are using a generator, be sure to tell your HVAC service provider.

HVAC systems can require substantial electrical power, and generator connections need the right capacity and proper installation. Some service appointments may need to wait until regular utility power is restored. Never try to connect or modify HVAC electrical equipment yourself.
