Each season asks something different of the wiring in a Dallas house, and each has a few things you can safely check yourself.
Weather in North Texas puts a house’s electrical system through four different tests. Spring brings lightning, hail and wind; summer keeps the air conditioner running for weeks at a stretch; autumn is mild and settled; and winter, usually gentle, can turn to a hard freeze within a day.
Two rules hold in every season. If a breaker trips, reset it once, and if it trips again, leave it off and call. If you see smoke or sparks or smell something burning, leave the building and call 911 first.
Spring thunderstorms are the season’s main test. Nearby lightning, a limb across a line or power switching back on after an outage can all send a surge through the house, and the damage may not show at once: a thermostat, a doorbell transformer or an air conditioner’s control board can fail some time later.
Surge protection works best in layers: a whole-house surge protector at the panel limits what comes in from outside, and plug-in protectors at computers and televisions handle what is left. During an outage, unplugging electronics and switching off large appliances spares them the jolt when power returns; one lamp left on shows when it is back.
Rain finds its way into outdoor outlets with cracked or missing covers. A GFCI that trips during a storm is doing its job; one that will not reset once things dry out needs a look. Before the season’s first pump, fountain or string of lights, press the test and reset buttons on each outdoor GFCI, and fit in-use covers that stay closed while a cord is plugged in.
After hail or high wind, look from the ground where the overhead line meets the house. A bent mast, a line pulled loose or a damaged meter base calls for a professional, and a downed line should be treated as live and left alone. Which side of the meter the damage sits on decides who repairs it: the utility, or an electrician doing storm damage repair.
Summer is the season of steady, heavy load. In a long hot spell the air conditioner can run most of the day for weeks, and heat makes every connection in its path work harder: a terminal only a little loose in spring can be running hot by late summer, at the breaker or at the outdoor disconnect.
Heat and load also find weak breakers. A breaker that trips on a hot afternoon may be worn, may sit loosely on the panel’s bus, or may be protecting a circuit that is simply overloaded. Note what was running when it tripped, since that often points to the cause. A breaker that keeps tripping calls for a repair, never for a larger breaker on the same wire.
Attics grow far hotter than the air outside. Old cable insulation turns more brittle, connections in attic junction boxes bake, and recessed lights not rated for contact with insulation can overheat where insulation is piled against them. Attic work is safest early in the day, whoever does it.
Garages hold heat too, which matters for EV chargers. Charging is a long, steady load, so a worn receptacle or a loose connection shows up as heat at the plug or the breaker, and some chargers slow themselves down when they run hot. A plug that feels hot or looks discolored is a reason to stop charging until the circuit and the charger installation have been checked.
Autumn brings some of the mildest weather of the year to North Texas, and with it the easiest conditions for planned electrical work. The air conditioner rests, attics cool enough to work in, and a few hours without power on part of the house is easy to live with.
That makes it a sensible season for projects that take planning: a panel upgrade before holiday cooking, lights and guests add to the load, rewiring an older house before the heating season, or new circuits for a workshop. Planned work begins like any other, with a visit and a plan you agree to.
It is also a good time to test smoke and carbon monoxide alarms, before the furnace and the fireplace see heavy use. Press each test button, replace batteries where the alarm takes them, and check the date on the back: most manufacturers call for replacing a smoke alarm about ten years after it was made. Smoke detector installation is part of our work.
Shorter days bring outdoor lighting back into use. Photocells and timers drift or fail, older fixtures let water into their sockets, and a GFCI that trips each evening when the lights come on points to moisture or a failing connection somewhere on the circuit. Holiday lights belong on outdoor GFCI outlets, with outdoor-rated cords and no more strands joined end to end than the packaging allows.
Winter in Dallas is short and mostly mild, but a hard freeze can arrive within a day and hold for several. Ice brings down limbs and lines, demand climbs as heaters across the region switch on, and outages can run long. It helps to know where the panel is, and which breaker feeds what, before that week comes.
Space heaters are hard on circuits. A typical heater draws about 1,500 watts on high, roughly 12.5 amps, which leaves little room on a 15-amp circuit shared with lamps, a television or a second heater. Plug a heater straight into a wall outlet, never an extension cord or a power strip, run one per circuit, and keep it about three feet from bedding, curtains and furniture. An outlet or plug that feels hot is a reason to stop.
When the power goes out, a portable generator must never be connected by plugging it into an outlet. A cord with plugs on both ends back-feeds the house wiring, can send power out through the transformer to lines where crews are working, and can start a fire when utility power returns. Run the generator outdoors, well away from doors and windows, with heavy outdoor extension cords to the few appliances that matter.
The safe way to run part of the house from a generator is a transfer switch or a panel interlock installed by an electrician, with an inlet on an outside wall. Either one separates the house from the utility before the generator feeds it, and lets you choose the circuits that matter: the furnace blower, the refrigerator, a few lights. Which one fits depends on the panel, and either usually needs a permit; where the panel is old or full, plan the connection together with a panel upgrade.
