How to Prepare Your Home's Electrical System for Winter in Brew City

Around Milwaukee, winter changes how we use electricity at home. It's dark by 4:30, so the lights stay on longer. We spend more time inside, too, whether we're cooking Sunday dinner or watching the Packers. Meanwhile, the furnace, humidifier, and maybe a space heater or two are all running, often right alongside the holiday lights.

All that extra demand can show the weak spots in your electrical system. Getting ready for winter is mostly about finding those weak spots now, before the coldest weeks of January arrive.

Test Smoke and Carbon Monoxide Alarms

With the windows shut and the heat running for hours, working smoke alarms and carbon monoxide alarms matter more than ever. Press the test button on each alarm to make sure it sounds. If your alarms use batteries, put in a fresh set.

Next, check the date printed on the back of each alarm. Smoke alarms usually need replacing after about 10 years, while carbon monoxide alarms often last five to seven years. Finally, make sure no alarms have been taken down, painted over, or blocked by furniture or decorations.

Check the Outlets Used by Heating Equipment

Whether you have a furnace or an older boiler with radiators, your heat depends on electricity to run. Without opening anything up, look at the cords, switches, and outlets you can see near your heating system. Watch for scorch marks, damaged cords, or plugs that sit loosely in the outlet.

Check the outlets used by humidifiers, space heaters, and heated blankets, too, since these often run for hours in winter. A plug that feels warm or loose is worth having an electrician look at. Leave the inside of your electrical panel and heating equipment to a professional.

Use Portable Space Heaters Carefully

A space heater can make a chilly room in an older bungalow or duplex a lot more comfortable, but it needs careful use. Always plug it straight into a wall outlet. Skip extension cords and power strips, since most aren't built to handle a heater's steady power draw.

Keep at least three feet of space between the heater and curtains, bedding, or furniture. If the cord or plug is damaged, stop using the heater. Models with tip-over protection and automatic shutoff add another layer of safety.

Look for Electrical Problems Before Holiday Lighting Goes Up

Before you hang the lights, take a few minutes to look for any existing electrical problems. Small issues can get worse once holiday decorations add more load to your circuits.

Watch for these warning signs:

• Lights that flicker or dim
• Outlets that feel loose
• Outlet or switch covers that feel warm
• Breakers that keep tripping
• Buzzing sounds
• Burning smells

If you notice any of these signs, hold off on the decorations until an electrician checks things out. Holiday displays add load to circuits that may already be struggling, especially in older Milwaukee homes with fewer outlets and circuits.

Prepare for Winter Power Outages

Heavy snow, ice, and strong winds can bring down power lines across the Milwaukee area. Keep flashlights and fresh batteries where you can find them in the dark. Charge your battery packs before a storm so you can keep your phones running during an outage.

If you're thinking about a generator, plan ahead with a licensed electrician. A standby generator or a properly installed transfer switch lets backup power reach your home safely. Never plug a portable generator into a wall outlet. That can send power back onto the utility lines and put line crews in danger.

Always run portable generators outside, away from doors and windows. Never use one inside your home or garage, even with the door open, because carbon monoxide can build up fast. When the power comes back on, whole-home surge protection can help protect your electronics and appliances from power spikes.

Check Exterior Outlets and Covers

Snow, ice, and slush can all reach your outdoor outlets during a Wisconsin winter. When moisture gets into damaged equipment, the risk of a shock or short circuit goes up. Pick a dry day and walk around your home to check each outdoor outlet, including the ones on your garage.

Look for these problems:

• Broken or cracked covers
• Outlets that feel loose in the wall
• Damaged cords
• Missing weather covers

Outdoor outlets should have weather-resistant covers and GFCI protection, which shuts off power fast if it senses a problem. If yours are missing either one, an electrician can update them before the worst weather hits.

Does Your Panel Keep Up With Winter Demand?

Winter puts extra demand on your electrical panel. A single breaker trip often has an easy explanation, like a space heater and microwave running on the same circuit. In that case, unplugging one of them and resetting the breaker usually solves it.

A breaker that keeps tripping, though, needs a professional to take a look. The cause could be an overloaded circuit, a wiring problem, or a circuit breaker that's wearing out. Many homes around here still have older panels, or even fuse boxes. Age alone doesn't mean you need a new panel, but an electrician can check whether yours can safely handle your home's needs.

When an Electrician Should Take a Look

Many of these checks are simple things you can do yourself. Some signs, though, call for an electrical inspection from a licensed electrician.

Contact an electrician if you notice:

• Breakers that keep tripping
• Scorch marks around outlets or switches
• Outlets or switch plates that feel hot
• Buzzing or crackling sounds
• Sparks
• Burning smells
• Water near electrical equipment

Don't wait on these problems, especially in winter when your system is working harder. Turn off the affected device if you can do it safely, and leave the electrical repair to a licensed electrician. When it comes to electrical work, our motto is simple: don't do it yourself.
