I have my water filtration system installed about 7 years ago by Home Comfort Centre. Recently the faucet has started leaking very slowly so I called Home Comfort Center and the saleperson Keith was extrememly friendly and helpful. He quickly found out that my system was still covered by warranty (parts) and arranged an repair appointment. The technican was very friendly and knowledgble as well. Overall the after-sale experience with Home Comfort Center has been good.
