"We had a few cold bedrooms upstairs and a cold breakfast nook surrounded with windows off the kitchen. The rooms furthest from the furnace were either too cold or too hot depending on the season. And in my situation, we weren't able to install new ductwork in that area because we couldn't get to it. The new Arzel zoning system allowed us to use existing equipment and ductwork. Now, the heating and cooling is directed to the rooms that needed it rather than the whole house. The temperature in the upstairs bedrooms and the breakfast nook is great." — John Ugo

"Our home is one and a half stories with a finished walkout basement. We have very high cathedral ceilings in the living room and until recently, we had very uneven heating and cooling throughout the house. We had a few rooms that wouldn't cool in t he summer and wouldn't get warm in the winter. Plus, our infant's room and kitchen both face the south and were very hot. Our son still naps during the day and there was just no way to keep his room cool. So, we had to do something. We had all kinds of suggestions from tearing out the ductwork to replacing the entire heating and cooling system with one that was oversized. We were so frustrated we even tried installing a new system, but it still didn't do the job. I had heard about zone control for some time and finally called to learn about the Arzel system. Our Arzel zoning system was installed in one day and we noticed a big difference right away. We've already noticed that our heating bill is reduced about 10%. With my two small children, I had to keep the whole house warmer. Now, I can turn down everything except for the three bedrooms. It definitely works... my wife is very happy with it." — Dave Warpell

"Ours is a very large, two year old, 3 story home with a walkout basement and we had a major heating and cooling problem. The upstairs was unbearably hot in the summer and the lower level was freezing. The builder we used and even the equipment installer didn't know how to remedy the situation. We investigated every possibility, but didn't want to do anything to the house that would ruin its appearance. We learned about the Arzel zoning system through an advertisement and called to learn more. The company was great to work with. After they examined the situation, they assured us that the problem could be solved. Within a day, they had installed a complete 4-zone system and our new home has never been more comfortable. My husband says it's the best thing we've ever done to this home, he just wishes it could have been part of the original mortgage. We're very thrilled with the system and are extremely glad that there was something out there that could solve our problem." — Janet Falcon

"We own a good-sized, three story home that was built in 1995. Our biggest problem was the master bedroom. And, while summers are rather short here in Michigan, we'd have at least a month when my husband couldn't sleep because the bedroom was too hot. We looked into many options to try to solve the problem. We even called five or six different companies and none of them could come up with a feasible solution. Some recommended equipment attached to the outside, but we felt that would detract from the looks of the house. Finally, we heard about the Arzel system on the radio and wanted to learn more about it. It sounded like a perfect solution so we went ahead with it. We haven't been through a hot summer with it yet, but heating in the whole house is tremendously better... especially the master bedroom. We had Arzel zone dampers installed throughout our ductwork and now we can adjust the temperature down in rooms we don't use, and be comfortable in the ones we do use. We're very comfortable and like the fact that the system comes with a great guarantee which gives us time for a complete and thorough testing." — Mrs. Sandy Porter
