Hi we are johnny and Jackie from airdrie our furnace died and reached out to comfort union for a replacement the staff there was extremely polite starting with Ian who went over all the details and was true his word the technicians they sent Mohamed and Darryl were very professional and Mohammed stayed extra hours to make sure everything was right good job and much appreciated
I had Asif and Mo replace our 33 year old natural gas furnace with an IBC combi boiler, IBC air handler and Gree heat pump & coil. They took extra time to explain how the system works and addressed all my many questions!!! Thank you! Looking forward to reliable and safe heating, cooling and hot water for years to come.
Our furnace unexpectedly failed and we needed a replacement right away. Ian at Comfort Union made it a priority to provide a quote same day. The installation team lead by Mohammad were professional, took the time to explain the new furnace and left the house tidy. I would recommend this company.
Frequently Asked Questions About Furnace Installation & Replacement in Calgary
How much does furnace installation cost in Calgary?
Furnace installation in Calgary typically costs between $4,900 and $11,000 all-in, depending on the model, home size, and installation complexity. Single-stage furnaces run $4,900–$7,500, two-stage furnaces $6,000–$9,000, and modulating furnaces $8,700–$11,000. All Comfort Union quotes include equipment, labour, City of Calgary permits, and inspection, no hidden costs. Financing is available from $70/month with approved credit.
How long does a furnace installation take in Calgary?
Most furnace installations in Calgary take one day, typically 4–8 hours. This covers removing the old unit, installing the new furnace, connecting venting and gas lines, filing City of Calgary permits, and a full system test before the technician leaves. More complex jobs involving ductwork changes or venting relocation may require two days. Comfort Union confirms the timeline at your free estimate so there are no surprises.
Do I need a permit for furnace installation in Calgary?
Yes, a permit is required for virtually all furnace installations and replacements in Calgary. The City of Calgary issues a gas permit to a licensed gas fitter covering the appliance, venting, and gas line. Comfort Union handles all permits and City of Calgary inspections on your behalf, included in your installation price. You never deal with paperwork, we manage everything so your installation is fully legal, warranted, and documented.
Should I repair or replace my furnace in Calgary?
Use the $5,000 rule: multiply your furnace’s age by the repair cost. If the result exceeds $5,000, replacement is almost always the better investment. For example, a 15-year-old furnace with a $400 repair = $6,000, replacement makes sense. Under 10 years old with a minor repair, fix it. Calgary’s extreme winters also accelerate furnace wear, so furnaces over 15 years old typically benefit from replacement even before they fully fail.
What size furnace do I need for my Calgary home?
Calgary homes generally require 30–60 BTU per square foot. An average 1,800 sq ft Calgary home typically needs a furnace in the 60,000–80,000 BTU range. However, proper sizing requires a full Manual J load calculation, which accounts for your home’s insulation, ceiling height, windows, and layout. Comfort Union performs this calculation at your free in-home estimate at no charge. An oversized furnace short-cycles and wears out faster; an undersized one can’t keep up on Calgary’s coldest nights.
What is the best furnace for a Calgary home in 2026?
For Calgary’s climate, with winters regularly dropping to −25°C, a high-efficiency two-stage or modulating furnace rated 96% AFUE or higher is the best choice. Comfort Union recommends the Carrier Performance Series (97% AFUE, two-stage) as the best value for most Calgary homes, and the Carrier Infinity Series (98.5% AFUE, modulating) for maximum comfort and energy savings. Both include a 14-year parts and labour warranty and Lifetime Heat Exchanger Warranty.
How much can I save on energy bills with a new furnace in Calgary?
Replacing an old 60–70% AFUE furnace with a new 96–98.5% AFUE Carrier furnace typically saves Calgary homeowners $300–$700 per year in natural gas costs. Calgary’s long heating season often 6+ months means efficiency improvements have a larger impact here than in most Canadian cities. A high-efficiency furnace generally pays for itself in energy savings within 7–10 years, while providing significantly better comfort throughout.
Is financing available for furnace installation in Calgary?
Yes. Comfort Union offers 0% financing for 6 months on approved credit, with monthly payments starting from $70/month. A new furnace is a significant investment, financing lets you replace your furnace immediately without delaying until it fails completely, which in Calgary can mean a cold home in the middle of winter. Ask about financing options when you book your free in-home estimate.
What warranty comes with a new furnace installation in Calgary?
Every furnace Comfort Union installs includes a Lifetime Heat Exchanger Warranty, as long as you own your Calgary home. Parts and labour are covered for 14 years through our manufacturer-backed warranty, one of the longest coverage periods in the Calgary market. All warranties are registered on your behalf and provided in writing at the time of installation. If the system doesn’t achieve the promised temperature range, we replace it at no cost, that’s our Right-Size Guarantee.
How do I choose a furnace installation company in Calgary?
Look for a company that is a licensed Alberta contractor, carries WCB coverage, has verifiable Google reviews from real Calgary homeowners, and provides a written quote with no hidden costs. Ask specifically whether they handle City of Calgary permits, what warranty covers both parts and labour, and whether they perform a load calculation to properly size your furnace. Comfort Union is a Carrier Authorized Dealer, BBB Accredited, and holds Alberta contractor licence #16356719, all verifiable credentials.
