How May 1st Electricity Changes Affect Your Appliances – Tips from Arni Services
Starting May 1, 2025, Ontario’s electricity rules switch to summer time-of-use (TOU) periods, which could affect your bill if you’re not ready. At ARNI Services, we fix appliances like fridges, washers, and air conditioners across Ontario every day, so we know how much power they use. This blog post explains the May 1st changes in plain words, shares real numbers on appliance energy costs, and gives you clever tips to save money while keeping your appliances in great shape. Let’s get started!
What’s Changing on May 1st in Ontario?
On May 1, 2025, the Ontario Energy Board (OEB) shifts to summer TOU periods, which run until October 31. This changes when electricity costs more or less, based on when you use it. According to the OEB, here’s how it works:
- On-Peak (11 a.m.–5 p.m.): Highest rates, because air conditioners and other appliances spike demand in the hot midday.
- Mid-Peak (7 a.m.–11 a.m., 5 p.m.–7 p.m.): Medium rates, when usage is moderate.
- Off-Peak (7 p.m.–7 a.m., weekends, holidays): Cheapest rates, when demand is low.
For example, running your dryer at noon (on-peak) could cost twice as much as running it at 8 p.m. (off-peak). If you’re on a tiered plan, the summer threshold drops to 600 kWh/month from 1,000 kWh in winter, meaning you hit the higher rate sooner if you use a lot of power. Ultra-low overnight plans don’t change. Check with your utility, like Hydro One or Alectra, for your exact plan

How Much Power Do Your Appliances Use?
Appliances like fridges, dryers, and ACs are big energy users, and the summer TOU periods make timing matter. Here’s what common appliances use yearly, based on 2024 OEB and ENERGY STAR data:
- Refrigerator (10+ years old): 600–800 kWh/year (newer models: ~350–450 kWh).
- Clothes Dryer: 600–800 kWh/year (depends on load size and vent condition).
- Washing Machine: 100–250 kWh/year (hot water cycles use more).
- Window Air Conditioner: 500–1,200 kWh/year (varies by size and use).
Let’s say on-peak rates are $0.20/kWh and off-peak are $0.10/kWh (OEB’s 2024 TOU estimates). Running a dryer for one hour on-peak costs $0.60, but only $0.30 off-peak. Over a month of daily loads, that’s a $9 difference just for one appliance! With summer’s on-peak hours hitting midday, your AC or fridge could push bills higher if they’re not efficient.
Clever Tips to Save Money and Protect Your Appliances
We’ve fixed thousands of appliances at ARNI Services Appliance Repair, and we’ve got some unique tricks to help you save energy during Ontario’s summer TOU periods. These aren’t your usual tips—they’re straight from our repair toolbox:
- Try the “Evening Cool-Down” for AC
Summer’s on-peak hours (11 a.m.–5 p.m.) are brutal for air conditioners. Pre-cool your home by running the AC early (7–9 a.m., mid-peak) and use fans to keep air moving during on-peak hours. This cuts AC use when rates are highest. Also, swap your AC filter every 1–2 months—a dirty filter makes it use 10–15% more power, per ENERGY STAR. - Test Your Fridge with a Paper Trick
A weak fridge door seal leaks cold air, making it run harder and spike your bill. Close the door on a piece of paper—if it slides out easily, the seal’s bad. A new seal can save $50–$75 a year, especially during on-peak hours. Keep coils dust-free too; a quick vacuum every six months boosts efficiency. - Use a Sock to Speed Up Drying
Dryers are energy hogs, and clogged vents make them worse. Clean the lint trap every load, then toss a clean, dry sock into heavy loads like towels. It absorbs moisture and cuts drying time by up to 10%, saving energy. We also recommend an annual vent cleaning—clogged vents waste power and cause 15,000 dryer fires a year, says the National Fire Protection Association. - Set a “Night Owl” Laundry Schedule
Move big appliance use to off-peak hours (7 p.m.–7 a.m.). Many washers and dishwashers, like those from Samsung or LG, have delay-start buttons. Set them to run at night or early morning to hit the cheapest rates. This also reduces strain on your appliances during hot midday hours, extending their life. - Spot Energy Leaks with a $5 Outlet Tester
Small appliances like microwaves or toasters draw “standby” power even when off. Grab a cheap outlet energy monitor (available at Canadian Tire) to see what’s using power. Unplug culprits or use a power bar you can switch off. This can save $10–$30 a year, which adds up with summer TOU rates.
Why Appliance Repairs Save More in Summer
With midday on-peak rates, an inefficient appliance can cost you a fortune. A fridge with a bad seal or an AC with a clogged filter uses way more power, and summer heat makes it worse. At ARNI Services, we’ve seen a single repair—like fixing a dryer’s thermostat—cut energy use by 20% and prevent a $1000 replacement. Regular maintenance, like cleaning vents or checking seals, keeps your appliances running lean and your bills low.
