By this point in the summer, most of us in the Catawba Valley have had the AC running non-stop for weeks. It's easy to not think twice about it — until a breaker starts tripping, or you notice the lights dim a little every time the compressor kicks on. 


I get calls like this every August. Someone's had their AC running fine for years, and suddenly it's tripping the breaker two or three times a week. Nine times out of ten, it's not actually the AC unit that's the problem — it's the electrical system trying to keep up with a load it wasn't really built for. 


Here's what's usually going on. Older homes, especially ones built before central air was standard, often have panels sized for a different era of electrical demand. Add a modern AC system — especially if it's been upgraded to a larger unit than what was originally there — and you're asking a panel that was fine for lights, outlets, and a window unit to now handle a lot more. 


A few signs it's worth having looked at:

  • Your breaker trips specifically when the AC kicks on, especially on the hottest days
  • Lights flicker or dim briefly when the compressor starts
  • The breaker feels warm to the touch (a real warning sign, not just an inconvenience)
  • Your panel is 20+ years old and you've added AC, an addition, or other major appliances since it was installed

None of this means you need to panic. Most of the time, it's a straightforward fix — sometimes it's just a matter of the AC being on a circuit that's shared with too much else, other times it does mean the panel itself needs an upgrade. Either way, it's worth having someone actually look at it and diagnose the real cause, rather than just resetting the breaker over and over through August and hoping it holds. If your AC's been giving your breaker a workout this summer, give us a call. We'll figure out what's actually going on and give you a straight answer on what it'll take to fix it.
