We recently had Comfort Union replace our traditional hot water tank with an IBC Tankless Boiler and water softener system, and the difference is incredible! As a large family, we now enjoy constant, consistent hot water—even when running multiple showers and the washing machine simultaneously. The upgrade has been a game-changer for our household. From start to finish, the team delivered top-tier service. Asif provided a thorough in-home estimate, answering all our questions with expertise. The installation was seamless, and Muhamad followed up to ensure everything was working perfectly. Their professionalism, knowledge, and attention to detail made the entire process stress-free. We highly recommend Comfort Union for anyone considering a plumbing or heating upgrade. Outstanding workmanship, excellent customer service, and a solution that truly meets our family’s needs. Thank you!

I recently had the pleasure of working with Comfort Union for three major installations in my home—a new heat pump, a tankless water heater, and a furnace—and I couldn’t be happier with the entire experience!

Heat Pump Installation: From the first consultation, Comfort Union’s team impressed me with their knowledge and transparency. I decided to upgrade to a heat pump because I wanted to improve energy efficiency and take advantage of both heating and cooling from one system. The team carefully assessed my home’s layout and explained every step of the process, including how the heat pump would function in Calgary’s colder climate. They even took the time to break down the cost savings I could expect over time.

The installation was seamless. The technicians were punctual, professional, and clearly experts in their field. They worked efficiently, ensuring that all components were correctly installed, and even took extra care to tidy up after themselves. They walked me through the setup, explaining how to use the system, and answered all of my questions patiently. Now, I enjoy year-round comfort with a system that’s quiet, effective, and eco-friendly!
