Summer utility bills in Ottawa are driven largely by cooling, especially in older homes that lose conditioned air more easily. Practical steps such as setting the thermostat a little higher, using ceiling fans, replacing filters, and reducing indoor heat from cooking can make a noticeable difference.

Even small habits add up: use blinds during the hottest part of the day, run full loads of laundry and dishes, and shift heat-producing chores to cooler hours. Shade trees and better sealing around doors, windows, and ducts can help older Ottawa homes feel more comfortable without overworking the air conditioner.
