Why Natural Gas Bills Spike in Alberta Winters
If you’ve lived through even one Alberta winter, you already know the feeling: that first December gas bill that’s two or three times what you paid in August. With furnaces running around the clock through stretches of –30°C, natural gas typically accounts for the single largest line item on an Alberta household’s winter utility bill.
The good news is that most of that bill is within your control. Small, inexpensive changes to how you heat your home, use hot water, and maintain your equipment can cut your natural gas consumption by 15–25% — and you don’t need to gut-renovate your house to get there.
Below are practical, proven ways to lower your natural gas costs heading into this winter, sorted by how quickly they pay for themselves.
Understand What You’re Paying For
Before you can cut your gas bill, it helps to know what’s on it. A typical Alberta residential natural gas bill has three main components:
- Commodity charge — the cost of the gas itself, priced per gigajoule (GJ). As of September 18, 2026, Get Energy’s 30-day floating discount average is $3.58/GJ, and the fixed Discount Advantage rate is $3.77/GJ.
- Delivery and transmission charges — set by your local distributor (ATCO Gas in most of Alberta), not your retailer. These don’t change when you switch providers.
- Administration and rider fees — small monthly charges including your retailer’s admin fee.
Because delivery charges are fixed regardless of who supplies your gas, the most direct ways to save are: (1) use less gas, and (2) make sure you’re on a competitive commodity rate. You can compare current rates on our rates page and learn more about gas pricing in our natural gas pricing guide.
Quick Wins: Things You Can Do This Weekend
1. Turn Down the Thermostat (Strategically)
Every 1°C you lower your thermostat saves roughly 3% on your heating bill. You don’t have to shiver — try these stepped adjustments:
- Daytime when home: 20–21°C instead of 22–23°C
- Sleeping: 17–18°C (a cooler bedroom actually improves sleep quality)
- Away at work: 16–17°C
A programmable or smart thermostat makes these setbacks automatic. Models like the Ecobee or Nest learn your schedule and adjust without you thinking about it. A smart thermostat typically costs $150–$300 installed and pays for itself in one to two heating seasons.
2. Seal Drafts Around Doors and Windows
Air leaks are the number-one reason furnaces work harder than they need to. Common culprits include:
- Gaps around exterior doors (check the bottom sweep and weatherstripping)
- Older double-hung windows — especially if you can feel cold air near the frame
- Where plumbing, gas lines, or electrical wiring penetrate exterior walls
- The attic hatch, if it doesn’t have a weatherstripped seal
Weatherstripping and caulking materials cost under $30 at any hardware store and take an afternoon to apply. For a detailed room-by-room approach, see our fall furnace and weatherization checklist.
3. Lower Your Hot Water Temperature
Water heating is the second-largest gas consumer in most Alberta homes after space heating. Your hot water tank likely came from the factory set to 60°C (140°F). If yours is higher, dial it down to 49–54°C (120–130°F) — hot enough to prevent bacteria, cool enough to save 5–10% on your water heating costs. The dial is usually near the bottom of the tank.
4. Use Exhaust Fans Sparingly
Kitchen and bathroom exhaust fans are necessary for moisture control, but leaving them running longer than needed pulls heated air straight out of your house. Run them only while cooking or showering, then switch off within 15 minutes after.
Medium-Effort Upgrades That Pay Off Fast
5. Replace Your Furnace Filter — and Keep Replacing It
A clogged furnace filter forces the blower to work harder and reduces heat transfer. In Alberta winters, check your filter every month and replace it when it looks grey or matted — most homes go through a filter every one to three months during heating season. A pack of standard filters costs $15–$30 and takes two minutes to swap.
6. Insulate Exposed Hot Water Pipes
If your hot water pipes run through an unheated basement, garage, or crawlspace, wrapping them in foam pipe insulation (about $1 per metre at a hardware store) reduces heat loss and means you get hot water faster — so you run the tap for less time.
7. Add or Top Up Attic Insulation
Alberta building codes have changed over the decades, and many homes built before the 2000s have attic insulation below current standards. The recommended level for Alberta is R-50 to R-60 in the attic. Blown-in cellulose or fibreglass is relatively inexpensive — professional installation runs roughly $1,500–$3,000 for a typical bungalow, but it can cut heating costs by 10–20% and usually pays back within three to five winters.

8. Use Ceiling Fans in Reverse
Most ceiling fans have a small switch on the motor housing that reverses the blade direction. In winter, set the fan to spin clockwise on low speed. This pushes warm air that collects near the ceiling back down into the living space — especially helpful in rooms with high or vaulted ceilings.
Bigger Moves for Bigger Savings
9. Upgrade to a High-Efficiency Furnace
If your furnace is 15+ years old, it’s likely a mid-efficiency model rated around 80% AFUE (Annual Fuel Utilization Efficiency). Modern high-efficiency condensing furnaces run at 95–98% AFUE, meaning nearly all the gas you pay for becomes heat instead of going up the flue.
A new high-efficiency furnace costs $4,000–$7,000 installed in Alberta, but the 15–18% improvement in efficiency can save $300–$500 per year on gas, depending on home size and usage. If your current unit is approaching end-of-life, the payback is strong.
10. Consider a Heat Pump (Yes, Even in Alberta)
Modern cold-climate heat pumps work efficiently down to –25°C to –30°C and use electricity instead of gas for most of the heating season, switching to your gas furnace only during extreme cold snaps. With Alberta’s competitive electricity rates — Get Energy’s 1-year Discount Advantage rate is currently 6.57¢/kWh as of September 21, 2026 — a heat pump can reduce your gas consumption by 40–60% while keeping total energy costs comparable or lower.

11. Upgrade Windows in the Coldest Rooms
You don’t need to replace every window in the house at once. Focus on the rooms that are always cold — usually north-facing bedrooms or large picture windows. Upgrading from single- or double-pane to triple-pane, argon-filled windows in those areas can noticeably reduce drafts and lower the heating load on your furnace. Look for ENERGY STAR® certified windows rated for Zone 2 (which covers most of Alberta).
Lock In a Competitive Gas Rate
None of the tips above matter as much if you’re overpaying for the gas itself. Many Alberta households are still on the regulated Rate of Last Resort, which fluctuates monthly and has no price certainty.
With a fixed-rate plan from a competitive retailer like Get Energy, you know exactly what you’ll pay per gigajoule for the length of your contract — no surprises when the cold snaps hit. Here’s a quick comparison using current rates as of September 18, 2026:
- Get Energy Floating Discount Average: $3.58/GJ (30-day average)
- Get Energy Fixed Discount Advantage: $3.77/GJ
Switching takes about five minutes and there’s no disruption to your service — your gas still flows through the same pipes from the same distributor. Only the commodity supplier on your bill changes. See how it works on our switching page, or jump straight to today’s rates.
How Much Can You Realistically Save?
Let’s put some numbers to it. A typical Alberta household uses 100–140 GJ of natural gas per year, with roughly 60–70% of that consumed between October and March. Here’s what the savings look like if you stack a few of the strategies above:
- Thermostat setback (2°C average): ~6% reduction → saves $40–$60/year
- Air sealing and weatherstripping: ~5–10% → saves $35–$70/year
- Hot water temperature reduction: ~3–5% → saves $20–$35/year
- Attic insulation top-up: ~10–15% → saves $70–$100/year
Combined, that’s $165–$265 per year in gas savings alone — before factoring in any rate savings from switching to a more competitive plan. Over five years, you’re looking at $800–$1,300 back in your pocket.

Frequently Asked Questions
What uses the most natural gas in an Alberta home?
Space heating — your furnace — accounts for roughly 60–65% of residential natural gas consumption in Alberta. Water heating is second at 15–20%, followed by cooking and clothes drying.
Does turning down the thermostat at night really save money?
Yes. Lowering your thermostat by 3–4°C for eight hours overnight can save 5–10% on your heating bill. The furnace does run harder to recover in the morning, but the energy saved during the setback period more than offsets it.
Is it cheaper to heat with natural gas or electricity in Alberta?
At current rates, natural gas is still less expensive per unit of heat delivered by a standard furnace. However, a cold-climate heat pump running on electricity delivers 2–3 units of heat per unit of energy consumed, which can make electricity competitive or cheaper for heating. Our gas vs. electric heating comparison breaks down the math.
How do I know if my furnace is running efficiently?
Check the yellow EnerGuide label on your furnace for its AFUE rating. If it’s below 90%, you have a mid-efficiency unit. Other signs of reduced efficiency include uneven heating, frequent cycling on and off, unusual noises, and gas bills that keep climbing despite stable weather. An annual furnace tune-up ($100–$150) can restore lost efficiency and catch problems early.
Can I switch gas providers mid-winter?
Absolutely. There’s no service interruption when you switch your gas retailer in Alberta — your distributor (ATCO, for most areas) continues delivering gas through the same infrastructure. The switch typically takes one to two billing cycles. Visit our rates page to see current options.
