1. General Safety Precautions
- Ensure personal safety first: Before checking any HVAC system, confirm that it’s safe to re-enter your home.
- Turn off power: Make sure to turn off the power to your HVAC system at the breaker before inspecting it to prevent electrical shock.
- Check for water damage: If your HVAC system has been submerged in water or exposed to flooding, do not turn it on until it's inspected by a professional.
2. Inspect Outdoor Unit (Condenser)
- Check for debris: Remove any leaves, branches, or other debris from around the outdoor unit.
- Inspect for physical damage: Look for dents, cracks, or other signs of physical damage to the unit’s structure.
- Check for flooding: If the outdoor unit was submerged, it may require a professional inspection. Water can damage electrical components.
- Clear the area: Ensure the area around the unit is clear for airflow, typically a 2–3 feet radius.
3. Inspect Indoor Unit
- Check for water damage: If the indoor unit (furnace or air handler) was in an area prone to flooding, inspect for any signs of water damage.
- Inspect the air filter: Replace the air filter if it’s wet or dirty, as a clogged or wet filter can lead to poor performance.
- Check for mold: High humidity and water exposure can lead to mold growth in and around the indoor unit. Look for mold near ducts or in the HVAC system.
4. Electrical System Check
- Inspect wiring and connections: Look for any visible damage to electrical components, wires, and connections around the HVAC unit. Exposed wires or burnt smells could indicate issues.
- Check the circuit breaker: Make sure the circuit breaker hasn’t been tripped during the storm. Do not reset it if you detect water damage or electrical issues.
5. Ductwork Inspection
- Inspect ducts for damage: Check for loose, disconnected, or damaged ducts, especially if your home experienced high winds or flooding.
- Check for leaks: If ducts were submerged, there may be potential leaks in the system that could reduce efficiency or cause water damage.
6. Test the System
- Turn on the power: Once you have confirmed there is no water or electrical damage, restore power to the HVAC system.
- Run a test: Start the system and monitor its operation. Ensure the air is flowing properly, there are no unusual noises, and the unit cycles on and off normally.
7. Professional Inspection
- Schedule a professional inspection: If your HVAC unit was exposed to water, high winds, or shows signs of damage, contact a certified HVAC technician to inspect and service it before resuming normal operation.
8. Additional Considerations
- Check the thermostat: Make sure the thermostat is functioning correctly and has not been damaged by water or power surges.
- Monitor for strange odors: If you smell burning, mildew, or anything unusual, shut the system down immediately and seek professional help.
