I had arranged with Abdul to have a tankless water heater installed and my old 50 gal tank removed . Ulmo and Tankeh arrived on schedule and the whole job was done to my complete satisfaction.
I would recommend them highly.

Professional company. I got a competitive quote. Technician came on time, completed the work and cleaned up after. Took about 2 hrs to remove the old tankless and install the new unit. A smooth process and I'm happy with the work. Thank you.

Kathy Toth
I had a regular hot water tank replaced with a tankless type by HVAC Ontario. Abdullah and Bilal were very helpful, courteous and professional from the start and even with after care. The technicians they sent who installed the furnace were very caring and professional as well. They walked us through how the system work. Awesome!
Neil Abam
Abdul and the team did a great job answering all our questions - took the time out to do a site inspection at our request. We never felt pressured about any of the decisions we needed to make. And ultimately our system works great! I definitely would recommend them to anyone. You wont regret it.
