Furnace Replacement Calgary

Is it time to replace your furnace in Calgary? Don’t let the process overwhelm you. At Comfort Union, we’re here to guide you through every step of the furnace replacement journey. Here’s why choosing the right furnace replacement and service provider is essential:

Here’s why choosing the right furnace and service provider matters:

Upgrading to a newer, more efficient furnace can lead to significant energy savings, reducing your environmental impact and monthly bills.

Replacing old unit with modern up-to-date system help mitigate frequent repairs and inconsistent heating. A replacement furnace offers reliable comfort, keeping your home cozy year-round.

A modern furnace provides better heating performance, ensuring consistent warmth throughout your home without hot or cold spots.

Avoid the hassle and stress of dealing with an old, unreliable furnace. With a replacement unit, you can enjoy peace of mind knowing your new heating system is up-to-date and reliable.

At Comfort Union, we specialize in seamless furnace replacements, making the process hassle-free for you. Our expert techs inspect the old furnace for vital components like the heat exchanger or furnace air flow to determine whether your furnace needs replacement or not. If they’re repairable, we will let you know. 

Replacement Factors to Consider

Selecting a furnace with a strong warranty is critical due to the inevitable wear and tear on mechanical components. The speed of warranty processing can greatly affect comfort during the winter. Brands like ICP (Keeprite, Comfortmaker..) may take a few days for part replacements, which isn’t ideal in colder seasons. In contrast, Carrier & Trane excel with efficient warranty service, often resolving issues within hours.

Comfort Union’s Warranty Offer: Comfort Union enhances this with a 12-year warranty on units and a lifetime replacement for the heat exchanger on Carrier and Trane models, with regular maintenance. This commitment underscores the importance of choosing a furnace brand and installer not only for its product and service but also for the warranty and support backing it, ensuring reliability and peace of mind during its long lifespan.

When it comes to furnace breakdowns, the availability and cost of replacement parts are crucial considerations. Certain brands, like Lennox, are known for having proprietary parts that can be more expensive. This is a key factor to keep in mind when choosing a furnace brand.

Availability and Cost: Carrier and Trane stand out in the Calgary market for their extensive availability of parts at competitive prices. This is particularly important because, in the event of a malfunction, readily available parts can significantly reduce downtime and repair costs.

Market Share Insight: The Calgary furnace market has been largely dominated by brands like Carrier and Lennox for decades. This historical market presence has resulted in a wide network of available parts and service options for these brands.

Recommendation: For ease of maintenance and cost-effectiveness in the long run, we advise opting for brands with a substantial market share in Calgary. This strategy not only helps keep the repair costs down but also minimizes inconvenience or instant replacement to save homes during cold weather by ensuring that parts are easily procurable.

The question of which furnace brand outlasts others involves subjective analysis and varies based on industry experience. However, Carrier, Trane, and Lennox emerge as the front runners in terms of durability, according to industry insights and customer feedback.

Carrier and Trane: Built to Last Both Carrier and Trane are celebrated for their robust engineering, which allows their furnaces to endure neglect, harsh conditions, and still deliver unparalleled comfort with long lifespans. These attributes solidify their status as industry titans.

Lennox: A Strong Contender Lennox, while also highly durable, may have specific considerations regarding parts and maintenance that can affect its longevity and operational costs.

Why Durability Matters Choosing a furnace from one of these leading brands means investing in a system designed to offer reliable performance over many years. The ability to withstand harsh conditions and maintenance lapses without significant detriment to their operation places Carrier and Trane slightly ahead in the durability domain.

When it comes to selecting a furnace from the three major brands—Carrier, Trane, and Lennox—the decision often comes down to pricing and what the customer values most in their heating system.

Trane: Premium Pricing for Unmatched Comfort Trane stands out for being the most premium-priced option among the three. Customers who opt for Trane are typically those willing to invest more upfront for the brand’s reputation for unmatched comfort and reliability.

Carrier: The Durable and Balanced Choice Carrier is celebrated for its durability, offering a great balance between cost, efficiency, and long-term reliability. Its pricing is competitive, often seen as equivalent to Lennox, making it a preferred choice for those seeking a robust system without the premium price tag of Trane.

Lennox: Comparable Pricing with Carrier Lennox, with pricing similar to Carrier, also offers high-quality furnaces. The choice between Carrier and Lennox may come down to specific features, warranty terms, or personal preference based on the brand’s reputation and customer service.

At Comfort Union, we offer competitive prices for Carrier and Trane furnaces. Our efficient cost management allows us to pass on these savings to our customers, ensuring they receive high-quality heating solutions at the best value.

The quality of furnace installation is just as critical as the brand you choose. At Comfort Union, our installers are not only factory-trained but also carry the necessary licenses and certifications, ensuring that every installation meets the highest standards.

Emphasizing Proper Sizing and Installation One of the most common issues with furnace performance and longevity is improper sizing and installation. To address this, we conduct a thorough furnace commissioning report for every installation, ensuring the correct sizing and optimal setup for your home’s specific needs. This step is crucial for avoiding the inefficiencies and breakdowns that often result from mismatched systems or incorrect installation practices.

The Cost-Quality Correlation It’s important to recognize that the lowest price often doesn’t equate to the best value, especially when it comes to furnace installation. Companies that offer significantly lower prices may cut corners on materials, skip essential steps in the installation process, or have less qualified technicians. While it might be tempting to save money upfront, these compromises can lead to higher costs over time, including more frequent repairs, reduced efficiency, and even the premature need for replacement.

Investing for Long-Term Peace of Mind Considering that a well-installed furnace can last 20+ years, investing a bit more upfront for professional installation is wise. This investment not only ensures your system operates at peak efficiency but also provides greater peace of mind, knowing that your home will be comfortably heated for many years to come without unnecessary interruptions or additional expenses.

When considering furnace brands, it’s often advisable to choose a reputable and premium brand for long-term reliability and cost-effectiveness. Lesser-known or budget brands might initially appear to be a more economical choice, but they can sometimes lead to higher costs over time due to the following reasons:

  1. Cost of Repairs and Parts: Furnaces from lesser-known brands may have higher repair and parts costs. This is often because their parts might be less readily available, or they may require specialized knowledge for repairs.
  2. Durability: Premium brands typically invest more in research and development, leading to more durable and efficient products. This often translates to fewer repairs and a longer lifespan for the furnace.
  3. Warranty and Service Support: Established brands generally offer more comprehensive warranty terms and reliable customer support. This can significantly reduce the hassle and expense of dealing with potential issues.

Furnace Installation FAQs

What is average cost of new furnace?

For most Calgary homes, you can expect the price range for a new furnace to fall between $5,500 and $6,800, including installation for homes with little to no ducting adjustments and no chimney liner upgrade. 

How long does furnace installation take?

The duration of furnace installation depends on various factors, including the complexity of the new equipment installation and the condition of existing ductwork and air conditioning systems installed in your home. Typically, a professional HVAC company technician can complete a standard furnace unit installation within a day (6-8 Hours). However, if additional work like duct modification or upgrading air ducts is needed, it may take longer. 

Why is furnace installation so expensive?

Furnace installation costs stem from various factors. It covers not just the furnace but also skilled labor for installation, which involves handling gasfitting, ducting work, plumbing, venting, electrical systems, multiple tools, and fully stocked vans that cost $80-$100K. Additionally, costs for furnace installations often include updates for better efficiency and compliance with Calgary’s building codes, like fitting advanced, energy-saving furnaces or adding smart thermostats and air conditioners. Operating a professional furnace company also incurs significant overheads, including insurance (general, property, WCB, auto), software subscriptions, marketing, payroll expenses (CPP, EI), health benefits, inventory management, warehouse rent and staff, fleet and fuel expenses, uniforms, tools, city of Calgary permits, accounting, legal, taxes, regular employee training, warranty cost, and consumables. They make up to 20-30% cost per job for a smaller company like Comfort Union while larger companies can be upwards of 40%.

Is Single Stage or 2 Stage Furnace Better?

In deciding between a Single stage and 2-stage furnace, consider your climate, home size, and efficiency needs. A single stage furnace, less expensive upfront, operates at full capacity when on, suitable for milder climates and smaller homes but less energy-efficient. A 2-stage furnace, more costly initially, runs mostly at a lower setting, providing more consistent and efficient heating, ideal for larger homes and colder regions. Choose a single stage for budget-friendliness and milder climates, or a 2-stage for improved comfort and efficiency in colder areas. 2 Stage low fire runs 80% of the time saving you money in the long run. The cost difference between the 1 Stage vs. 2 Stage is usually $500-$1,100

Absolutely thrilled with Comfort Union! A friend recommended them, and it turned out to be an excellent suggestion. We were on the hunt for an efficient air conditioner with a higher SEER rating and a quiet unit, preferably with side discharge (smaller footprint). From the start, the team at Comfort Union was fantastic. They booked us for an estimate, walked us through our options, and recommended a GREE Flexx cold climate heat pump. The 20 SEER rating, 55 dB noise level, and variable speed compressor made the GREEE heat pump a smart investment over an air conditioner.Installation was a breeze—they completed everything in just one day. The crew was incredibly professional, and they also installed an Ecobee smart thermostat, which required fishing wires up to the second floor. They took the time to educate us about the system and ensure everything was running smoothly.I'm extremely satisfied with their work and highly recommend Comfort Union to anyone in need of HVAC services in Calgary!Kenneth

I spent almost one year to find the best HVaC replacement company and finally landed with Comfort union .I initially thought it was a small job but then realized the magnitude of work and effort it goes into it ..Asif initially came to my house , explained to me everything in detail including what is code of guidelines expected by city of Calgary , that showed his knowledge on the whole process ..Then came his brother Moore for installation - you will never find such a wonderful person who knows in and out of the HVAC and moreover the most patient person I have ever seen .. he did the whole installation with absolute craftsmanship and love for the work he did .. the best part was his perfectness and every work he did was so perfect and tidy !Finally, came Khan ji - to do the final inspection to add perfectness over the perfectness carried by Moore .. He did inspection and made sure everything was 200% correct ..Overall , I would recommend comfort union over any other service provider …Replaced my furnace , water tank and my humidifier …

I had an issue with my furnace, went to reset my main breaker to power cycle trying to troubleshoot it... Breaker crapped out so I was sitting on an electrical, and furnace problem.Gave these guys a call and they were able to come out within 2 hours. Required a full main breaker replacement, and new gas valve on my furnace. They diagnosed it in only a couple hours, and fixed everything the same day.Had a great experience, the technicians that showed up were professional, and very knowledgeable. I'll definitely be using these guys when I eventually have replace my aging furnace.
