Seasonal Electrical Maintenance Checklist for NZ Homes

What to Check in Summer vs. Winter

The changing seasons in New Zealand affect your home's electrical needs. Summer brings high humidity and long daylight hours. Winter brings frosty mornings and more heater use. Each season poses unique challenges—and risks—to your electrical systems.

This guide breaks down seasonal electrical maintenance tips for NZ homes and shows how regular inspections keep your household safe and help your systems last longer, avoiding expensive fixes. At Mako Electrical, we believe in routine care. A yearly electrical check-up can spot issues and keep your home running well throughout the year.

Why Seasonal Maintenance Matters in NZ

New Zealand's climate changes a lot across regions—from the subtropical Far North to the snowy South Island. As seasons change different parts of your electrical system face stress. Think about it: you need heaters and electric blankets in winter and fans, air con, and outdoor lighting in summer. This can wear out circuits, trip breakers, or even make fires more likely over time.

Checking your home each season helps you spot small issues before they grow into bigger (and pricier) problems. More than that, it keeps your family safe.

What to Check in Summer: Staying Cool and Efficient

Summer in NZ can put a strain on your home's electrical system when you use fans, air conditioning units, and outdoor features like garden lights or pool pumps more often.

Here are the main areas to check in summer:

1. Outdoor Lighting & Power Outlets

With BBQs, garden parties, and longer evenings, you'll use your outdoor lighting and sockets more in summer. Keep an eye out for:

• Wires that have cracks or are exposed

• Lights that flicker or cause circuits to trip

• Water getting into outdoor sockets

If you see damage or old fittings, you might need to schedule an outdoor electrical inspection.

2. Surge Protection

Summer storms happen a lot in NZ, and they often cause power surges. One lightning strike can destroy appliances . Surge protectors help shield your devices—this matters if you work from home or own pricey electronics.

Check that your surge protection system is current and set up at the switchboard level. Mako Electrical provides surge protection installation and testing to help you feel safe.

3. Fans and Air Conditioning Units

Summer's the time to check these systems, whether you have ceiling fans or heat pumps in cooling mode. Look at:

• Filters for dust buildup

• Wiring for wear signs

• Circuit loads if you run multiple appliances at once

If your heat pump hasn't been cleaned or inspected for over a year, you should book a maintenance visit.

What to Check in Winter: Staying Warm Without Risk

Winter brings a surge in energy use. You run heaters more often, use the dryer more, and keep indoor lights on longer. This extra load makes winter upkeep crucial.

1. Heating Systems and Wall Outlets

Electric heaters, heat pumps, and underfloor heating systems need close attention. Older homes often face issues with overloaded circuits.

Check:

• Whether outlets feel hot or make buzzing sounds

• Any discoloration or burning smells near power points

• Lights that flicker when big appliances start up

Winter is the best time to get Mako to check your electrical safety to stop sudden power cuts—or something even worse.

2. Switchboard & RCD Testing

Cold months lead to more use of appliances that need lots of power like kettles, dryers, and electric blankets. Your switchboard must be in good shape to handle this load.

Get your residual current devices (RCDs) checked to ensure they can still spot problems. If your board is old or doesn't have RCDs, think about letting Mako Electrical upgrade it.

3. Electric Blankets and Appliance Safety

Before you plug in electric blankets, look them over for:

• Frayed cords

• Broken controllers

• Uneven heating when on

These small problems can start fires. Unplug electric blankets when you're not using them, and buy new ones if they look worn out.

Tips to Keep Your Home Safe All Year

Some jobs depend on the season, but you should do others all year:

• Check smoke alarms once a month

• Get an electrician to inspect your whole house every year

• Look for signs of mice or rats—they often bite wires and insulation

• Write clear labels on your switchboard so you can find things fast if the power goes out

Mako Electrical can help you create a yearly plan just for your home so you don't forget anything important.

Promoting Regular Check-ups

Your home's electrical system needs consistent care just like your car needs regular servicing. A lot depends on safe efficient power - lights, appliances, home security, and even your work-from-home setup. This makes it worth your while to invest in seasonal inspections.

Customers who choose yearly checks often avoid unexpected breakdowns and gain from early spotting of system problems. Mako Electrical offers priority booking and service reminders to keep you protected from one season to the next.
