The 3 Best Furnace Brands for Calgary Winters

A good furnace that’s well maintained will last for 20 years or more. It’s a serious investment for any homeowner — and not just in terms of furnace installation costs

Your choice of furnace brand will impact your comfort for years to come and can make a difference in your repair and energy bills. That’s why it’s so important to do your research and find out which furnace is the best option for you.

Having serviced thousands of furnaces each year over our past 14+ years in business, we’ve seen every make and model out there. Based on our experience, we’d like to share our picks for the top 3 furnace brands available in Calgary.

Lennox is our top pick

Lennox is the brand we choose to offer to our clients. With proven durability, technological innovation, high-efficiency, and a reliable product, it’s a great fit for all types of homeowners. The other two brands we considered are strong contenders but, ultimately, with Lennox you get more bang for your buck.

How we chose the best furnace brand

We rated furnace brands based on the following criteria:

  • Their ability to generate sufficient heat even during the most unforgiving Winter cold snaps.
  • How long they last, frequency of repairs.
  • How easy they are to maintain (you don’t want to have to hunt down and custom order specialty filters).

On top of these factors, some will offer limited warranties and even come with other features like smart thermostats (accessible from your mobile device), advanced air filtering, and more.

As you read this, you’ll discover the top brands share a great deal in common.

  • Almost all offer an Annual Fuel Utilization Efficiency (AFUE) rating of 95% or higher. This is the percentage of heat produced for every dollar of fuel consumed.
  • They’ve been in business for over 100 years.
  • All are known for manufacturing quiet, efficient, reliable furnaces.

1. Lennox


  • Lennox products are known for reliability and durability. They’re built with high-quality materials and high-quality workmanship, meaning they’ll last for years to come. And they’re up to the challenge on even the coldest Calgary winter day.
  • Lennox offers a wide range of Energy Star® qualified furnaces.
  • As one of the largest brands on the market, Lennox has 2 large, corporately-owned parts distribution centres in Calgary, meaning they will almost certainly have parts for your furnace on hand locally for as long as you have your furnace.
  • There are many thousands of Lennox furnaces installed in Calgary. This means service companies have lots of exposure to Lennox furnaces of all ages, meaning they have probably seen an issue before and will know what the most effective fix is.
  • Lennox’s iComfort smart thermostats are leaders in home automation with Apple HomeKit and Android Home integration. If you’re a fan of smart technology, they offer lots of great add-ons and compatibility features.
  • Lennox has many indoor air quality options available through their Healthy Climate product line, including HEPA filters, humidifiers, UV lights, and their unique Pure Air System.


  • With their focus on quality and market innovation, they can be a bit pricier than lower-end competitors.
  • To qualify for a 10-year parts warranty on the Merit series furnaces, the homeowner must register the warranty with Lennox at the time of installation. Otherwise, the standard 5-year parts and 20-year heat exchanger warranty will apply. Although there is no cost to registering the warranty, if your installation does not make you aware of this or register it on your behalf, it can be missed. Elite and Signature series furnaces do not require warranty registration for the 10-year parts warranty or lifetime heat exchange warranty.
  • Quality comes at a price, so they are not the least expensive option available.

2. Trane


  • Trane furnaces are considered very high efficiency and are even Energy Star® certified.
  • Products are built to last and have a reputation for durability in all weather conditions.
  • A comprehensive warranty is offered for all Trane furnaces.


  • Very expensive equipment and repair parts are more expensive than competitors!
  • This brand doesn’t offer much for the tech-savvy user and doesn’t have many add-ons or additional features to offer aside from reliable furnace units. Trane’s proprietary Communicating Thermostat does not have direct Apple HomeKit or Android Home integration.
  • Trane has a smaller distribution centre in Calgary and relies on 3rd party suppliers to stock parts. Trane parts sometimes have to be ordered in if they have failed.
  • Fewer Trane furnaces are installed in Calgary than competitors, meaning service techs are less likely to have direct experience in servicing more obscure Trane models.

3. Carrier


  • Carrier offers a wide range of products to suit the needs of almost any price entry point.
  • Their top-end furnaces have some of the highest efficiency rates available in the industry.
  • Carrier offers a few more technological advances than Trane in their products.
  • Carrier has 2 corporately owned distribution centres in Calgary, meaning they have parts available.  


  • Inducer motors on new Carrier furnaces are some of the most expensive in the industry. An out-of-warranty inducer motor replacement can easily exceed $1,000.
  • Early versions of Carrier high-efficiency furnaces are prone to secondary heat exchanger plugging. We have found the Carrier Infinity Series and Bryant equivalent to having extremely high failure rates of the secondary heat exchanger with some of these furnaces needing a new secondary heat exchanger or furnace replacement after less than 10 years.
  • New carrier furnaces are extremely sensitive to the angle at which the furnace is installed. If the furnace has any backslope (possibly due to an uneven furnace room floor or a careless installer), the furnace has been shown to collect water in the secondary heat exchanger, leading to periodic and unpredictable shut down issues.
  • Carrier offers a disappointing warranty in comparison to its competitors, especially given its higher price point.
  • While Carrier does offer some technological features, they don’t have nearly as many features as Lennox’s iComfort thermostats or Indoor Air Quality products.

Furnace & Duct Cleaning Checklist




Quote guarantee

When we receive an online furnace or air conditioning quote request and the customer accepts the initial quote, we’ll send a comfort advisor to confirm the provided information and quoted price in person. 


If the comfort advisor finds any inaccuracies during the in person visit, we’ll revise the quoted price on the spot. After the quoted price is confirmed with an in person visit, the price is set. 


If there are unforeseen complications on the date of install, Advanpro will not pass the additional costs along to the customer. (See exceptions in Terms below.)



The guarantee is not valid if the customer provides inaccurate information when Advanpro seeks to confirm any information about the quote. This also applies to the on-site confirmation visit. 



In the exceptional circumstance that the chimney liner required for most furnace installations cannot be installed or gets stuck during installation, the guarantee no longer applies and we will provide a supplementary quote to complete installation. 


We do not warranty or guarantee customer-supplied thermostats.

Repair guarantee

If the diagnosed issue is not fixed by our initial repair, we will dispatch the first available service technician to return and fix it at no additional cost.


If we determine that there is an additional unrelated issue, there may be a charge for the additional repair.

Correct A/C sizing guarantee

If the air conditioner Advanpro installs is determined to be improperly sized for your home, we will supply and install the correctly-sized A/C condenser at no additional cost. 


Advanpro must be immediately notified of any install issues. The guarantee applies for 3 months, starting from the installation date. The guarantee no longer applies if, at any time after the quote or installation, modifications are made to the home that impact cooling requirements.

Correct furnace sizing guarantee

If the furnace Advanpro installs is determined to be undersized for your home, we will supply and install the correctly-sized furnace at no additional cost. 


Advanpro must be immediately notified of any install issues. The guarantee applies for 3 months, starting from the installation date. The guarantee no longer applies if, at any time after the quote or installation, modifications are made to the home that impact heating requirements.

Hot water tank types

Natural draft or atmospheric vented hot water tanks have a 3″ – 4″ steel vent pipe, which runs to a vertical chimney. The chimney is usually shared with standard or mid-efficiency furnaces.


Power vented hot water tanks have one or two black or white plastic vent pipe(s), which are 2″ – 3″ in diameter. The vent pipes usually exit from the side of the house.

A/C Tune Up

Regular preventative maintenance improves efficiency and extends the lifespan of your air conditioning system, with the following benefits:


  • Reduced electricity bills and operating costs. When the unit operates as designed, electricity usage is reduced.
  • Maximized cooling capacity. Home comfort on the hottest of days with minimum run time.
  • Minimized repair bills. Detect and fix small problems before they get worse.

HRV Cleaning

In Calgary, all homes built in 2016 or later have a Heat Recovery Ventilator (HRV). Some homes built or renovated after 2013 may also have an HRV. 


An HRV efficiently replaces stale indoor air with fresh outdoor air, all year round.


As with any other air-handling equipment in your home, your HRV should be cleaned regularly to ensure the best possible indoor air quality.


If you aren’t sure if you have an HRV, call our team to find out how you can tell.

Duct Work Sanitizing

If you or your loved ones suffer from respiratory issues or allergies, or you’re concerned about the quality of the air that you are breathing, then our sanitizing treatment will give you the reassurance that your ductwork is sterile and free of debris that could negatively impact your respiratory and overall health.


Microban is our hospital-grade sanitizing solution, which kills 99.99% of germs, viruses, funguses, molds, and other pathogens.


We also offer Benefect, an all-natural sanitizer made from plant extracts, which also kills 99.99% of germs, viruses, funguses, and molds. ​

Exhaust Flu Stack Cleaning

Mid-efficiency furnaces produce a sand-like, mildly-corrosive byproduct. This substance condenses in the exhaust flu stack and collects over time near the inducer/venter motor, restricting exhaust gas flow. Eventually, it enters the inducer motor and causes premature wear on the furnace.


Exhaust flu stack cleaning removes the build-up to reduce the chance of motor failure and maximize the life span of your furnace. Preventative maintenance ensures your furnace runs efficiently all Winter long — without costly no-heat emergencies. 

A/C + High-efficiency Bypass

The secondary heat exchanger in a high-efficiency furnace or A/C coil has delicate, closely spaced fins that must be protected during your furnace and duct cleaning.


For furnaces that require a bypass, we temporarily install a filter above the heat exchanger or A/C coil, and position our duct vacuum above the filter.


This bypass procedure prevents damage by ensuring all dust and debris in your supply duct work is collected before reaching the heat exchanger or A/C coil.


Standard furnaces without A/C don’t have secondary heat exchangers or A/C coils and don’t require the bypass procedure.

Furnace Tune Up

Regular furnace tune ups are essential to maximizing the lifespan and efficiency of your furnace, so you can rely on it to keep you warm all Winter long.​


During our 30+ point inspection, we check all furnace systems to identify components that are worn out and need replacement. Replacing parts before they break — preventative maintenance — maximizes heating efficiency, avoids no-heat emergencies, and saves on costly service calls. 


Home furnaces can last for 20 years or more if well-maintained. A professional furnace tune up every two years helps to preserve your investment for decades.

Reverse Octopus Whip Tool

The reverse octopus whip has eight 16” flexible tentacles, which whip around blasting high-pressure air in all directions as it moves through your duct work.


The tool agitates and dislodges the most hard-to-reach dust, debris, and contaminants, moving them toward our duct vacuum for collection and disposal.

Brush Cleaning Method

Our high-speed rotary brushing equipment sweeps the entire interior surface of your duct work, ensuring that all dust, debris, and pet hair are vacuumed away.


Physically cleaning the entire length of your duct work ensures that no contaminants are left behind, increasing your indoor air quality and peace of mind.

Dryer Vent Cleaning

Dryer fires are a top-five cause of house fires. Cleaning your dryer vent regularly greatly reduces the chance of a dryer fire, plus the following benefits:


  • Reduces clothes drying times
  • Lowers utility bills through greater efficiency
  • Extends the life span of your dryer
  • Lessens the amount of allergens in your house

Back Skipper Tool

The back skipper is a 1” diameter rounded ball connected to a long, flexible high-pressure airline.


The 1” ball has jets that discharge high-pressure air, pulling the tool and airline through the length of your duct work.


The high-pressure air moves the dust and debris toward our duct vacuum, where it is collected for disposal.​
