Tankless Water Heater Installation:
I also had Comfort Union install a tankless water heater (Rinnai RXP199), and it’s been a game-changer for my household. No more waiting for the water to heat up or running out of hot water during long showers—this tankless system delivers endless hot water on demand! Their installation team was fantastic. They emphasized the importance of proper installation for efficiency and to protect the warranty, which gave me peace of mind knowing I was in good hands. I appreciated that they took the time to explain the maintenance needs to ensure the system stays in top shape for years to come. Plus, they added smart touches like installing a drier filter for extra protection against Calgary’s colder months.
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 🙏🙏🙏
