Seasonal Electrical Maintenance for Hot Summers and Rainy Winters
Electrical systems around here get a hard year: long hot stretches when air conditioners run for hours, dry autumn winds that shake overhead lines and outdoor fixtures, and a short rainy season that finds every outdoor box with a bad cover. A few checks each season catch most problems while they’re still small.

Seasonal Checks
| Season | What to check | Why it matters | Do it yourself or call |
|---|---|---|---|
| Spring | Press test on every GFCI; look over outdoor covers | A GFCI can fail without anyone noticing | Yourself; call if one won’t trip or reset |
| Summer | Breakers and lights while the AC runs | Heat waves show whether the panel has room | Watch yourself; call if breakers trip or lights dim |
| Autumn | The service cable at the roof, outdoor fixtures, loose cords | Dry winds loosen lines and crack covers | Look from the ground; call for anything at the roof |
| Winter | Space heaters, holiday lights, outdoor boxes after rain | Overloaded outlets and wet boxes trip and heat up | Yourself; call if outlets feel warm |
Test Your GFCI and AFCI Outlets
Both kinds have a test button, and both should be tested about once a month. It takes a few minutes for the whole house.
- Plug a lamp or a night light into the GFCI outlet and switch it on.
- Press the TEST button. The lamp should go off and the RESET button should pop out.
- Press RESET firmly. The lamp should come back on.
- For AFCI breakers, press the test button on the breaker in the panel. It should trip to the middle or OFF; push it fully off, then on.
- If a GFCI doesn’t trip, won’t reset, or an AFCI won’t trip on test, mark it and call. It isn’t protecting that circuit.
Before a Heat Wave
- Run the air conditioner on a warm day and watch for dimming lights or a tripped breaker.
- Clear boxes, bikes and storage away from the panel so it can be reached fast.
- Plan the big loads: don’t run the dryer, the oven and the EV charger at the same time as the AC peak.
- Check that fans and window units plug straight into the wall, not into power strips.
- Know which breaker runs the AC, and label it if it isn’t.
What to Leave to an Electrician
Anything inside the panel, at the meter or up at the service mast is a job for an electrician and, for the lines themselves, the utility. The same goes for any outlet or fixture that’s warm, scorched or buzzing. If something on your checklist turns up a problem, our services page shows which visit fits.
Maintenance Questions
How often should a home’s electrical system be checked?
Test GFCIs and AFCIs monthly yourself. Beyond that, have the panel and wiring looked at when you buy an older house, before adding a big appliance, or whenever trips and flickers start to repeat.
Do smoke alarms count as electrical maintenance?
Hardwired alarms are on a circuit and have a battery backup. Press the test button on each one, and replace any that chirp or are past the date printed on the back.
What should I do after a wind storm?
Look at the service line from the street to your roof from a safe distance. If it’s sagging, pulled loose or down, stay away from it and call the utility first, then us for anything on the house side.
