Furnace Replacement Cost in Sherwood Park: 2026 Price Guide

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. (Prices are typical ranges for the Edmonton region.

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?
