Too Hot to Handle: How to Prepare Your Home for Heatwaves and Power Outages

July in Canada used to mean sunny days and the occasional summer storm. Now, thanks to climate change, it’s starting to mean heatwaves, humidity, and rolling blackouts, especially in cities like Toronto, Montreal, and Ottawa. With energy grids under strain and temperatures hitting record highs, homeowners need to think beyond air conditioning.

The rising risk of power outages during extreme heat can compromise your home security, endanger vulnerable family members, and damage your property. But with the right tools and preparation, you can keep your home protected and safe, even when the power goes out.

How Heatwaves Impact Your Home Security

You might not think of your alarm system as something that could be affected by heat, but it is. Here’s why:

• Power outages disable traditional wired systems without backup
• Wi-Fi can drop, making cameras and smart home devices unreliable
• Hot temperatures can trigger false alarms on heat-sensitive sensors

In short, without battery backup or cellular communication, your system could go offline exactly when you need it most.

Smart Systems That Stay Online Even When Power Doesn’t

At Alarm Guard, we design security systems that are built to handle tough conditions, including heatwaves and blackouts. Here’s what makes the difference:

• Battery backup: Our security panels and key devices automatically switch to backup power during outages, so your system keeps working.
• Cellular monitoring: Even if Wi-Fi goes down, your system stays connected to the monitoring centre using a secure cellular network.
• Smart alerts: Get instant updates on your phone about activity, low battery warnings, or triggered sensors, no matter where you are.

It’s peace of mind when you’re away, at work, or even just trying to sleep through a muggy night.

Keep Seniors and Pets Safe During Power Failures

Heatwaves can be dangerous, especially for seniors, children, and pets. If your home loses power for hours or even days, indoor temperatures can climb fast. Here’s how to stay ahead of the risks:

• Install temperature sensors that alert you when indoor heat reaches unsafe levels
• Use motion-activated cameras to check on pets or elderly family members if you’re not home
• Ensure battery-powered smoke and CO detectors are part of your system, especially if portable generators are in use
• Set up wellness checks through Alarm Guard if an elderly loved one lives alone

Simple Summer Prep Tips

Before the next heatwave hits, here’s a quick checklist to keep your home secure and summer-ready:

• Test your backup batteries and replace any that are low
• Check that your system’s cellular connection is active
• Install leak detectors. Blackouts can sometimes lead to pipe or sump pump failures
• Set smart thermostats or fans on timers to avoid overheating if power returns suddenly
• Use mobile app controls to monitor your home if you’re travelling or away at the cottage
