Furnace Replacement Cost in Sherwood Park: 2026 Price Guide
If your furnace is getting old, noisy, or expensive to repair, the first question is almost always the same: how much does a new furnace cost? In Sherwood Park, the answer matters more than in most places. Your furnace runs hard for six months or more every year, and a breakdown at -30°C isn’t something you can wait out.
This guide covers real price ranges for 2026, what should be included in a proper quote, how to tell if high efficiency is worth the money, how permits work in Strathcona County, and how to plan a replacement before your furnace forces the decision in the middle of winter.
Quick answer: how much does furnace replacement cost in Sherwood Park?
Most Sherwood Park homeowners pay roughly $4,500 to $9,500+ for a complete gas furnace replacement in 2026, including installation. A straightforward swap of a high-efficiency furnace sits at the lower end. Upgrades that need new venting, ductwork changes, or a premium variable-speed furnace sit at the higher end. Replacing your furnace and air conditioner together typically costs more overall but saves on combined labour.

2026 furnace replacement price ranges
| Type of project | Typical installed cost* | Best for |
|---|---|---|
| High-efficiency straight swap (same location and venting) | $4,500 – $6,500 | Most homes replacing a 15–20 year old furnace |
| Upgrade from an old non-condensing furnace (new PVC venting and condensate drain) | $6,000 – $8,500 | Older homes with original chimney-vented furnaces |
| Premium two-stage or variable-speed furnace | $7,500 – $10,000+ | Larger homes, comfort-focused upgrades, quieter operation |
| Furnace and central AC replaced together | $9,000 – $15,000+ | Homes where both systems are aging |
Ranges include equipment, labour, standard materials, and the gas permit. Your actual quote will vary.
What should be included in a furnace replacement quote?
This is where many homeowners get caught out. Two quotes can be $1,500 apart simply because one includes things the other leaves out. A complete quote should list:
- The exact furnace model number, with its efficiency rating (AFUE) and heat output (BTU)
- Removal and disposal of your old furnace
- Venting: new PVC intake and exhaust pipes if needed, and proper termination outside
- Condensate drain setup, and a condensate pump if your drain is far away
- Gas line connection and leak testing
- Plenum and duct connections adjusted to fit the new unit
- Thermostat: whether a new one is included or your existing one is reused
- Gas permit and inspection
- Start-up, safety testing, and combustion check
- Warranty details: both the manufacturer’s parts warranty and the installer’s labour warranty
- Product registration, which is required to get the full manufacturer warranty on many brands
If a quote is just one number on a page, ask for it to be itemized. A reputable contractor will have no problem doing that.
7 factors that affect your furnace replacement cost
1. Furnace efficiency (AFUE)
AFUE tells you how much of your gas actually becomes heat. A 96% AFUE furnace turns 96 cents of every gas dollar into heat for your home. Most furnaces installed in Alberta homes today are high-efficiency condensing models at 95% AFUE or higher. Higher-efficiency models cost more upfront but cost less to run, which matters a lot in a Sherwood Park winter.
2. Single-stage, two-stage, or variable-speed
Single-stage furnaces run at full power or off. They’re the most affordable option.
Two-stage furnaces run on low most of the time and switch to high on the coldest days. That means more even temperatures and quieter operation.
Variable-speed or modulating furnaces adjust in small steps for the most consistent comfort and efficiency. They also cost the most.
3. The right size (BTU)
Bigger isn’t better. An oversized furnace heats the house in short bursts, turns on and off constantly (short cycling), wears out faster, and leaves cold spots. An undersized one runs nonstop on the coldest nights. Proper sizing should be based on a heat-loss calculation for your home, not just the size of your old furnace. Many older furnaces were oversized to begin with.
4. Venting and installation complexity
If you’re replacing a high-efficiency furnace with another one in the same spot, installation is simpler and cheaper. If your old furnace vents through a metal chimney, the new one needs PVC venting through an outside wall plus a condensate drain, which adds labour and materials.
5. Ductwork condition
A new furnace can’t perform well if it’s connected to undersized, leaky, or poorly designed ducts. Minor plenum changes are normal. Major duct repairs add to the cost but can solve long-standing comfort problems.
6. Brand and warranty
Premium brands and longer warranties raise the price. Pay attention to the labour warranty from the installer, too. A great furnace with a poor installation is still a poor investment.
7. Timing
Planned replacements in the fall are easier to schedule than emergency replacements during a January cold snap, when demand is at its peak and you may be without heat while you wait.
Is a high-efficiency furnace worth it in Sherwood Park?
For most homes, yes, especially if you’re replacing a furnace that’s 20+ years old. Here’s a simple way to estimate your savings:
Savings ≈ 1 − (old AFUE ÷ new AFUE)
For example, replacing an older furnace running at about 65% efficiency with a 96% model:
1 − (65 ÷ 96) ≈ 32% less gas used for heating
If your household spends $1,500 a year on gas for heating, that’s roughly $480 a year back in your pocket. Over a furnace’s 15–20 year lifespan, that adds up to thousands, and Sherwood Park’s long winters make the payback faster than in milder parts of Canada.
(Your actual savings depend on your old furnace’s real efficiency, your home’s insulation, and gas prices. Your technician can help you estimate them more accurately.)
Repair or replace? A quick way to decide
Use the $5,000 rule: multiply your furnace’s age by the repair cost. If the total is over $5,000, replacement is usually the smarter investment.
- Example: an 18-year-old furnace with a $350 repair gives 18 × 350 = 6,300. Consider replacing it.
Also lean toward replacing if your furnace:
- is over 15 years old,
- needs repairs every season,
- has a cracked heat exchanger,
- heats your home unevenly,
- or your gas bills keep rising for no clear reason.

Why you shouldn't wait for your furnace to die in January
Most furnace replacements in Sherwood Park are emergency replacements. The furnace fails on the first truly cold night, and the homeowner has to decide quickly, with no time to compare options.
Planning ahead gives you:
- Time to compare furnace types, sizes, and quotes
- Flexible scheduling before peak season
- No nights without heat, and no risk of frozen pipes
- Time to arrange financing, if you need it
If your furnace is over 15 years old and has needed repairs recently, this fall is the best time to get a replacement quote, even if you decide to wait.
Furnace rebates and financing in Alberta (2026)
Let’s be honest about rebates. Alberta doesn’t currently have a broad provincial furnace rebate. The federal Canada Greener Homes Grant is closed to new applicants. Here’s what may still help:
- Manufacturer promotions: furnace brands often run seasonal rebates. Ask your contractor what’s available when you get your quote.
- Clean Energy Improvement Program (CEIP): in participating Alberta municipalities, eligible upgrades can be financed through your property taxes. Check whether your municipality currently participates.
- Contractor financing: monthly payment plans spread the cost of a new furnace over time. Sherwood Mechanical offers financing options for furnace replacement.
Be cautious of any company promising large government furnace rebates in Alberta. Ask for the program name and check it yourself.
Do you need a permit to replace a furnace in Strathcona County?
Yes. Replacing a gas furnace requires a gas permit and inspection under Alberta’s Safety Codes. In Strathcona County, gas permits are issued through the County’s online permit system. A licensed contractor normally applies for the permit for you and includes the cost in your quote.
Tip: always ask whether the permit is included. A quote without a permit may look cheaper, but unpermitted gas work can cause problems with your home insurance and when you sell your house.
5 red flags in a cheap furnace quote
- No model number listed, so you don’t know what you’re actually getting
- Sizing based only on your old furnace, with no questions about your home
- No mention of a permit
- Venting or condensate work left vague, which often turns into “extras” later
- No written labour warranty
The cheapest quote often becomes the most expensive furnace once callbacks, poor comfort, and early repairs are added in.
Frequently asked questions
How much does a new furnace cost in Sherwood Park?
Most homeowners pay roughly $4,500 to $9,500+ installed in 2026, depending on the furnace type, efficiency, size, and installation complexity.
How long does a furnace replacement take?
Most straightforward replacements are completed in one day. Installations that need new venting or duct changes may take longer.
What size furnace do I need?
It depends on your home’s heat loss, which is affected by its size, insulation, windows, and layout. A proper load calculation is more accurate than simply matching your old furnace, which may have been oversized.
What’s the best time to replace a furnace?
Before it fails. Early fall and spring are ideal because scheduling is more flexible and you’re not without heat. That said, a failing furnace in winter should be replaced right away for safety and comfort.
How long does a new furnace last?
Most gas furnaces last about 15–20 years with yearly maintenance. An annual furnace tune-up helps protect your investment and keep your warranty valid.
Should I replace my AC at the same time?
If your air conditioner is over 10–12 years old, replacing both together can save on combined labour and ensure the two systems are properly matched. See our air conditioning replacement service.
