Beating the Heat: How to Keep Your London, Ontario Home Cool Without a Huge Hydro Bill
Summers in London, Ontario can get hot and humid fast, and keeping your home cool without watching your hydro bill spike is a challenge every homeowner in southwestern Ontario knows well. The good news is that with a few smart habits and small upgrades, you can stay comfortable all season without running your air conditioner around the clock. Here are practical, budget-friendly ways to keep your London, Ontario home cool this summer.
1. Time Your AC Around Peak Hydro Rates
London Hydro charges more during weekday peak hours, typically in the afternoon. Set your thermostat a couple of degrees higher during those hours and let it drop back down in the evening once off-peak rates kick in. A programmable or smart thermostat makes this easy and can noticeably lower your monthly bill.
2. Block the Sun Before It Gets In
South- and west-facing windows take the brunt of the afternoon sun. Closing blinds, curtains, or shades during the hottest part of the day, or adding reflective window film, blocks a lot of solar heat before it ever warms up your living space.
3. Use Ceiling Fans Strategically
Ceiling fans cool people, not rooms, by moving air across your skin. Set them to spin counter-clockwise in summer and only run them in occupied rooms. Pairing fans with a slightly higher thermostat setting is one of the simplest ways to cut cooling costs without sacrificing comfort.
4. Cook Outside When You Can
Running the oven on a humid evening heats up your kitchen and forces your AC to work harder. Take advantage of patio season and use the barbecue instead, keeping the heat outdoors where it belongs.
5. Seal Up Drafts and Gaps
The same weatherstripping and caulking that blocks winter drafts also keeps summer heat from sneaking in around windows, doors, and any spots where pipes or wiring enter your home. It's a low-cost fix that pays off in both seasons.
6. Check Attic Insulation and Ventilation
A poorly ventilated attic can radiate heat down into your living space, making upper floors uncomfortably warm. Proper insulation and ventilation, like soffit and ridge vents, help hot air escape. This is especially worth checking in older London homes and character properties.
7. Plant for Shade and Long-Term Savings
Trees or shrubs planted on the south and west sides of your property can significantly cut cooling costs as they mature. Even large potted plants or a pergola with climbing vines can reduce direct sun hitting your windows and siding.
8. Run Major Appliances at Night
Dishwashers, washers, and dryers generate heat and humidity, and they draw more power during peak pricing hours. Running them in the evening or early morning keeps your home cooler and takes advantage of lower off-peak hydro rates.
9. Get Your AC Serviced Annually
A well-maintained air conditioner runs far more efficiently than one with a dirty filter or low refrigerant. An annual tune-up before peak summer heat hits can prevent costly breakdowns and keep energy bills in check all season.
What Works Best for Your Home?
Every home in London, Ontario is a little different, and what keeps a century home in Old North cool might not be the same as what works for a newer build in the south end.
