Signs Your Furnace Needs Repair

If you’re not familiar with some the warning signs that a gas furnace can send out when it needs a repair, read on! Your furnace might be saying “fix me” when:

  • There are lingering smells: It’s normal to smell fuel when you turn on your furnace for the first time each season. But it’s not normal when the smell of fuel hangs in the air for days or even hours. When that happens, you should turn off the furnace and call Comfort Union. We’ll get to the bottom of the problem.

  • Your gas furnace or heat pump is making weird noises. Some noises can be normal. But when your furnace is raising a ruckus, it’s telling you something is wrong. Our furnace technicians will have your system playing sweet music in no time.

  • It takes several tries to start your system: A system that sputters several times before starting may not be there for you when you need it most. This problem could be the result of a faulty thermostat or disconnected wiring.

  • The flame is yellow: Your pilot light should be blue. Any other color is a red flag and could mean your furnace has a ventilation problem.

  • Uneven Heating. If your thermostat is set properly, but your house isn’t warm enough, something is definitely wrong. Let us make it right

Furnace Calgary Repair FAQs

Who Should I Call for Furnace Repair Services?

Contact a licensed gasfitter or HVAC technician for furnace repair services. Technicians trained specifically for different equipment brands are crucial for accurate diagnostics, saving you money and avoiding hassle. They possess the necessary expertise to handle each unique system efficiently.

What is the Average Cost of Furnace Repair in Calgary?

In Calgary, the average furnace repair cost ranges from $400 to $1,400. About 50% of repairs average around $600, while the other 50% lean towards a $900 average. The cost depends on parts, availability, and labour time. Choosing a professional company with readily available parts can prevent additional costs from poor workmanship.

How Can I Repair My Furnace Myself?

It is strongly advised not to attempt furnace repairs yourself unless you are a licensed gas or HVAC technician. Gas-fired equipment can be hazardous, and improper handling, especially if the heat exchanger is malfunctioning, could lead to dangerous situations like flame bursts. It’s best to leave such repairs to professionals. 

What are the Costs Involved in Emergency Furnace Repair?

Emergency furnace repairs typically cost about 30% more than standard repairs due to overtime charges for technicians and potential overnight fees for part procurement from the manufacturer in the city, ranging from $100 to $200.

How Do I Repair a Gas Furnace?

Repairing a gas furnace should always be left to professional, licensed technicians. It’s city bylaws and against manufacturer guidelines to attempt DIY repairs on gas furnaces due to the serious risks involved.

What Does Furnace Repair Entail?

Furnace repair involves diagnosing the system through a series of checks, and making sure all electrical connections, wiring, gas, and pressure levels are optimal and according to the manufacturer’s specifications. It also includes locating the necessary parts and evaluating replacement vs. repair options.

How Much Should I Budget for a Furnace Repair?

For newer, warranty-covered high-efficiency furnaces, budget between $400 and $900 during regular hours. For older furnaces, expect costs to be slightly higher, typically around $600 to $1,400. Some repairs can be extremely costly such as out-of-warranty heat exchangers, potentially reaching $2,100 to $2,800 including warranty and labour.

How to Repair a Furnace Heat Exchanger?

Attempting DIY repairs on a heat exchanger is not advisable due to the technical expertise required and the potential safety risks involved with gas-fired equipment. Professional technicians have the training, experience, and tools necessary to handle such repairs safely and in compliance with local regulations and manufacturer guidelines.

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.
