Hamilton County is currently experiencing heavy flooding, and homeowners across Sheridan, Noblesville, Westfield, Carmel, Zionsville, and Fishers should take a few minutes to check on their hvac systems, including gas furnaces, air handlers, heat pumps, and air conditioners . Flooding is one of the most common — and most overlooked — causes of hvac damage in Indiana, and catching the problem early can save you from an expensive repair or full system replacement.

Why Flooding Is Dangerous for Your HVAC System

Your hvac system houses sensitive electronic components, wiring, and controls. When floodwater rises around or into the unit, it can:

• Short out electrical connections and control boards
• Cause gas valves to leak gas into the home
• Introduce silt, mud, and debris into the coils and fan assembly
• Corrode internal components over time, even after the water recedes
• Create serious safety hazards if the system is powered on while wet

Running a flooded unit, even briefly, can cause damage that isn't always visible right away.

HVAC Flood Safety Checklist

If your HVAC system has been exposed to standing water during this flooding event, follow these steps:

1. Turn off power at the breaker and shut off the gas to the unit righht away. Never run or attempt to test a flooded HVAC system. Shutting off power at the breaker box protects both you and the equipment.
2. Wait until it's safe to inspect. Once floodwaters recede, check the unit for visible mud, silt, leaves, and storm debris.
3. Don't attempt a DIY restart. Electrical components and compressors that have been submerged need a professional inspection before the system is powered back on.
4. Watch for warning signs. After power is restored by a technician, listen for unusual noises, weak airflow, or reduced cooling — all signs of underlying flood damage.
5. Document any damage. Photos of flooding around your unit can help if you need to file an insurance claim.
