I gave a 5 star rating only because of the actual work done by the workers. It was excellent. The schedulers however were not near as efficient. Every time I phoned they gave me a time of arrival that was unreliable. Once again I commend the workers for their skill, efficiency, courtesy and overall workmanship. I will consider Superior Plumbing on future jobs.

Great experience with Superior HVAC Gatineau. Booking was easy, communication was clear, and the technician was courteous and efficient. The HVAC system was checked properly and the repair was completed without delays.
