We bought an air conditioning and furnace system from Waterloo Energy Products several years ago and were very happy with their customer service. We've then, we moved to a new home that required a new furnace and AC. We immediately called Waterloo Energy and they came out to explain the different systems they have that were based on our needs. What I liked best is their incredibly knowledgeable, friendly customer service and they were patient with us after we asked 20 questions. Within a few days, our new Trane Furnace and AC was installed and it works perfectly. The service technicians who installed the unit were very professional, efficient, and knowledgeable. We've always get outstanding service.
