Summer AC Load and Your Electrical Panel
On a 90-degree July afternoon, your air conditioner, refrigerator, dehumidifier and maybe a pool pump are all running. That's when weak spots in your electrical system show up.
Request an electricianDimming lights
Lights dimming when the AC starts can mean a weak connection or an undersized service.
Hot breakers
Breakers that feel warm or trip in summer need checking.
Dedicated circuits
AC units, dehumidifiers and freezers should be on circuits sized for them.
Outdoor disconnects
The disconnect near the AC unit should be in good condition.
Hard-start kits
Some AC units benefit from start components that reduce startup surge; ask your HVAC contractor.
Panel capacity
Adding a second AC system or a pool may require more capacity.
Surges
Summer storms bring surges that damage AC electronics.
Get it checked
If problems show up every summer, have the panel inspected.
