I must say that he was a real gentleman!

I have had a Eco King C200 since 2018 and been very happy with the unit until the last little while started acting up, after contacting the company I was put in touch with James one of their technician and I must say that he was a real gentleman with the whole process of walking me through all the steps and diagnosis the issues and providing me with the information needed to get parts and after a few changes to the unit with new board and new gas valve the unit is back up and running as it should.

Thank you so much for all the help and support and specially after hours and on the weekends.

I absolutely recommend people to reach out to Eco-King and consider their products, they absolutely stand by them.

For the last 3 days I was without heat and hot water as our 10 year old Eco-King stopped working.

I phoned a company who had their label on the unit and they recommended a full replacement and gave me a verbal estimate of $18,000!

I decided to phone Eco-King to see if they could put me in touch with someone to come out and I was transferred to James who walked me through a bunch of troubleshooting steps over the phone and came by the next day and got my boilers working in under two hours and the cost of time and materials.

Unlike the company that recommended an $18,000 solution without a care for me, Eco-King and James in particular really does care about the homeowner.

I absolutely recommend people to reach out to Eco-King and consider their products, they absolutely stand by them.
