Arzel HVAC System

We heat or cool our homes to keep our family comfortable. but, a single thermostat in the living room can’t always keep the upstairs cool and the basement warm. Fact is, you may feel a 12 to 15 degree difference in comfort levels within your home. Heat from the sun can make one side of your home significantly hotter than the other side. What’s more, homes with large rooms or rooms with large ceilings can be very difficult to heat or cool. One thermostat in a typical home just can’t maintain suitable comfort levels throughout the entire home.
Now there is a surprisingly simple way to make sure that every area of your home is comfortable, and not just the room with the thermostat. With the Arzel Zoning System, you divide your home into separate comfort zones that not only cut your energy bills, but also allows you to set the comfort level of individual areas. Each zone gets it’s own thermostat you set to whatever temperature you want for that zone. This unique and patented damper system in your ductwork controls the flow of conditioned air and makes each zone a comfortable custom zone.
