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.

I highly recommend this team. Asif was incredibly helpful, clearly explaining the heat pump installation and the Greener Homes Loan process. Mohammed’s installation was top-notch; his attention to detail with the wiring and system integration was impressive. The entire process was smooth and professional. 5/5 for their great work, and I will definitely use their services again.

We hired Comfort Union in March 2024 to handle a full basement project—HVAC, a cold-climate heat pump, a Rinnai Sensei RX tankless water heater, gas-fitting for the dryer, stove, BBQ and furnaces, plus a Novo water softener and reverse-osmosis system. From the first phone call to the final walkthrough, every member of the team—Asif, Mohammad and the rest—was a pleasure to work with.
