Comfort Union replaced our furnace and tankless water heater, and we couldn’t be happier. We called other companies and Comfort Union was the best furnace company. They’re honest, hardworking people who truly care about their customers. We got a Carrier two-stage furnace and a Rinnai tankless water heater for our home. The team was patient, considerate and very helpful throughout the process. Highly recommend them to anyone in our beautiful city of Calgary! Thank you Ayoob, Amirt, Roshan, and Mohammed 🙏🙏🙏

I highly recommend Comfort Union! During a recent cold snap, I found myself without a furnace, and I received exceptional service. All of my options were clearly explained, and the team worked diligently until my home was heated again.
I felt valued as a customer and appreciated the honesty, expertise, and respect demonstrated by all. I am truly grateful for the service and support provided by Comfort Union. A sincere thank you to everyone involved.

We had called them for a furnace & AC tune-up and I couldn’t be happier with their service. Khan was friendly and extremely knowledgeable. He not only performed the tune-up but also repaired a damaged refrigeration line that was causing issues with our old AC unit. He explained everything thoroughly and provided helpful recommendations for future maintenance. My family loves their brand lol is quite adorable

Our furnace shut down early in the morning, and we called Comfort Union at 6:30 AM for an emergency furnace repair. A technician arrived within 2 hours, quickly diagnosed the problem, and found that our gas valve had caught fire. Since our furnace was 30 years old, it was time for a replacement. We had older parents so this had to be fixed immediately. By 2 PM the installation team arrived with Carrier furnace and not only replaced the furnace but also our 20-year-old water heater with new Bradford White. We are so grateful for their quick response, professionalism, and kindness.

Energy-efficient Carrier furnace paired with Bradford White water heater in a utility room.
