8 Questions You Should Ask Before Buying A New Furnace In Edmonton

Considering installing a new furnace in 2026 and wondering how to ensure you get a top-notch installation? The key is asking the right questions. This guide covers eight questions every Edmonton homeowner should ask contractors before booking their new furnace installation. Keep reading to learn more!

Question #1: How Do You Calculate Sizing?

A properly sized furnace is crucial. In Alberta, HVAC technicians are required to perform Manual J calculations for every furnace installation. This technical assessment determines your exact heating capacity needs based on square footage, insulation, Edmonton’s extreme cold (-40°C), and air infiltration.

If your contractor recommends a furnace without a proper assessment, this is a bad size. Instead, look out for teams that conduct comprehensive testing that surveys all the key elements of your home.

Question #2: What’s Included in Your Quote?

We’ve all been there: a quote that feels too good to be true, only to be hit with hundreds of hidden fees once the job is complete. Your contractor should be transparent about their quoting process. Typically, a new furnace quote in Edmonton includes prices for:

The new unit
Installation labor
Removal/disposal
Permits
Venting (if needed)
Condensate drain
Ductwork modifications (if required)

If you receive a vague quote with limited details, it might be best to consider other contractors.

Question #3: Is My Ductwork Adequate?

Your furnace relies on ductwork to function properly. If your new furnace is not compatible with your existing ductwork, you’ll be looking at some serious issues down the line. The right contractor will inspect your ductwork during their initial consultation and recommend modifications separately, if needed.

Question #4: What Brands Do You Install?

While proper installation is the most important aspect of a new furnace, understanding the brands that a contractor stocks and supplies is also a good idea. Look out for reputable and trusted brands like Trane or Lennox. An added plus? If they are a preferred dealer through these companies. For example, Weiss-Johnson is a Goodman A-Plus Platinum Dealer and has additional partnerships with Daikin and Trane.

Question #5: What Are Your Warranty Terms?

If something goes wrong, you should have a clear understanding of what is (and isn’t) covered. Typically, manufacturers offer 10-year warranties on equipment. When it comes to labour, coverage can be more complicated. Your contractor should give you a clear and honest answer on what to expect. Additionally, ask about how manufacturer warranty claims are handled. Will your contractor offer assistance? Or will you have to take care of everything yourself? These insights can help inform your choice for new furnace installations.

Question #6: How Long Will Installation Take?

You need to know what to expect on installation day. A standard furnace replacement typically takes 6-10 hours (usually one business day). If your furnace requires new venting or ductwork modifications, plan for 8-12 hours or even two days.

Your contractor should be clear about timing and what to prepare for. They should also let you know they’ll protect your floors and clean up after themselves. Vague timelines or unrealistic estimates are signs of disorganization and poor installation.

Question #7: What Financing Options Do You Offer?

Not everyone has $7,000 to put towards a new furnace. The right contractor offers flexible financing options to make your replacement affordable. Look for contractors that offer 0% financing for 12-24 months, payment plans, or access to any applicable rebate programs.

Question #8: What’s Your Emergency Support Policy?

Furnaces fail at the worst possible times—like 2 AM on the coldest night of winter. Your contractor should offer 24/7 emergency support from October through April. Ask about their average response time (aim for 2-3 hours in Edmonton) and whether after-hours calls include additional fees.
