System Failure After a Rolling Brown-Out
Understanding the difference between a Black-out and Brown-out.
A Black-outÂ
A blackout is an extended loss of power in a specific area. Until power is restored, all electrical appliances and systems in the affected area stop functioning.
A BROWN-OUT
A Brownout, otherwise known as a Rolling Brownout, is a deliberate reduction in voltage by the utility company to manage demand and avoid a total Blackout. This often results in dimming lights and reduced electrical appliance performance.
What to do if your HVAC Shuts Down After a Rolling Brown-Out
If your HVAC system shuts down during or after a rolling brown-out, it is essential to take specific steps to ensure it can restart safely and to avoid potential damage. Here’s what you should do:
- Turn Off the System – This prevents potential damage from power surges when the voltage returns to normal.
- Check For Damage – Inspect the system for any visible damage or tripped breakers. Reset any tripped breakers.
- Wait and Restart – After the voltage stabilizes, wait for a few minutes, then turn the HVAC system back on. Some systems have a built-in delay to protect the compressor, so it may take a few minutes to start.
- Call a Professional—If the system does not restart or you notice any unusual behavior (like strange noises or smells), contact a licensed HVAC technician for an inspection. A professional can perform a thorough inspection and address any issues that may have resulted from the brownout.
Preventative Measures for Future Protection.
Regular Maintenance –Â Schedule routine maintenance checks to ensure your system is in good working condition. This can help identify potential issues before they become significant problems.
Surge Protectors – Installing surge protectors can shield your HVAC system and other sensitive electronics from power surges that often follow brownouts and blackouts.
Back Up Power Solutions – Investing in a backup generator can keep your HVAC system running during prolonged outages, ensuring your home remains comfortable.
