What you need to know

Winter in Alberta brings colder temperatures, longer nights and naturally higher energy use especially for heating and lighting.听But small changes can make a big difference.

Here鈥檚 how to stay warm, save money and keep your home running efficiently this winter:

  • Maintain your furnace and airflow for steady, efficient heat
  • Seal up leaks and drafts to stop energy loss
  • Layer up, add humidity and use smart lighting to stay cozy while reducing waste
  • Spread costs evenly year-round with Average Billing

Short on time? Watch this quick video on simple winter prep steps that cut drafts, improve furnace efficiency and lower heating costs.

Choose a budget-friendly payment option

Heating demand peaks in winter, and so can your bill. To smooth out the highs and lows, consider our听Average Billing听option which lets you pay a rolling monthly average of your energy costs throughout the year.
That means fewer surprises during cold months and a more predictable budget overall.

Check your furnace and heating system

Your furnace does most of the heavy lifting in winter, so keeping it in good shape is one of the easiest ways to save energy and stay comfortable. Here鈥檚 what to focus on:

  • Install a furnace filter alarm to remind you when it鈥檚 time for a swap. Many models even whistle when the filter gets dirty.

  • Check your furnace filter every month during heating season and replace it if it鈥檚 dirty. A clean filter helps your system run more efficiently and use less energy.

  • Book a tune-up if your furnace is older or not running at its best. A professional maintenance visit can help improve performance without a full replacement.

  • Skip 鈥渃ranking the heat.鈥 Turning your thermostat way up won鈥檛 warm your home faster 鈥 it just makes your furnace work longer.

Heat only what's necessary

Save energy by focusing your heat where you actually need it most:

  • Close doors and vents in unused rooms to avoid heating empty spaces.

  • Skip uninsulated areas like garages, attics, and crawlspaces 鈥 they lose heat quickly and can drive up your energy use.

  • Use smart thermostats or programmable vents to control zones more precisely and keep your main living areas comfortable without wasting heat elsewhere.

Manage airflow for better efficiency

Good airflow helps your home heat evenly and keeps your furnace from working harder than it needs to.听Here鈥檚 how to improve airflow and heat your home more efficiently in winter:

  • Reverse your ceiling fan direction. In winter, set your fan to pull cool air up toward the ceiling. This helps push warm air back down into the room where you actually feel it.

  • Keep vents clear. Make sure furniture, rugs or appliances aren鈥檛 blocking air vents. Clear vents help your furnace move warm air efficiently throughout your home.

  • Use a heat recovery ventilator (HRV). HRVs improve indoor air quality by pulling out stale air and using its heat to warm up the fresh air coming in 鈥 giving you better ventilation without losing energy.

Maintain your fireplace and chimney

Your fireplace can add warmth and comfort 鈥 but it can also let heat escape if it鈥檚 not used efficiently.听Here鈥檚 how to use it efficiently and avoid unnecessary heat loss:

  • Keep warm air indoors. A chimney can act like an open window, letting heat escape. Always close the damper when the fireplace isn鈥檛 being used, and make sure the flue seal is tight.

  • Use smart fireplace habits. When you light a fire, open the dampers in the bottom of the firebox (if your system has them) or crack a nearby window slightly. Close doors to other rooms and lower your thermostat to around 10鈥13 掳C while the fire is burning.

  • Consider efficiency upgrades. Tempered glass doors or a heat-air exchange system can help circulate warm air back into your home.

  • Add more control. Installing a fireplace thermostat can help regulate heat output and prevent energy waste.

Seal up doors and windows

Even when they鈥檙e closed, doors and windows can let warm air escape and cold air sneak in.听Here鈥檚 how to keep cold air out and warm air in:

  • Check for cold spots. Place your hand on the inside of a closed door. If it feels noticeably cooler than your walls, it may be time to upgrade to a better-insulated door. This is especially important for entrances to garages, cold storage rooms and uninsulated basements.

  • Add low-cost insulation. A layer of clear plastic window film can make a big difference. It helps block icy drafts and adds extra insulation with very little effort or cost.

  • Use the sun to your advantage. Open curtains or blinds on sunny days to let in 鈥渇ree heat.鈥 Clean south-facing windows to maximize sunlight. Once the sun sets, close your curtains to help trap warmth indoors.

Quick win: Weatherstripping around door and window frames is an easy way to reduce drafts and lower heating loss.

Layer up and stay warm naturally

Sometimes the simplest habits can help you stay comfortable while using less heat.

  • Add layers. Put on a cozy sweater or warm socks and lower your thermostat a few degrees to save on your heating bill.

  • Use area rugs. Rugs help insulate cold floors and make rooms feel warmer, plus they cut down on noise and add a bit of comfort underfoot.

Upgrade to smarter lighting

Winter鈥檚 long, dark evenings mean your lights work overtime 鈥 but they don鈥檛 have to use more energy. Make lighting more efficient by installing automatic timers, motion sensors, dimmers, or solar-powered lights around your home. These small upgrades help cut electricity use without sacrificing comfort or brightness.

Add humidity for comfort and savings

Moist air feels warmer, which means you can stay comfortable even with your thermostat set a little lower. Adding a humidifier to your home can help maintain ideal indoor humidity levels in winter.

And here鈥檚 a bonus: houseplants and aquariums naturally add moisture to the air, giving your home a small humidity boost while keeping things cozy.
