Customer Service at its best

Garry was incredibly nice and took the time to assist in resolving an issue and even contacted the company to have additional filters sent to the house due to the unique size and my difficulty in finding at the home improvement locations. Truly exceeded expectations.

Great friendly service

Very knowledgeable and had lots of tips. I just wish I hadn't cut him off on the hot water heater flushing tip. Maybe he'll see this and let me know? Great service!
