Zoning & Ductwork

The Benefits of Zoning

Comfort
• Solves the problem of rooms that are too cold or too hot
• Allows you to set the temperature you want, when you want it, where you want it

Conservation
• Only condition occupied zones
• Save up to 30% when combined with programmable thermostats

Convenience
• Flexibility of a thermostat in each zone
• No need to return to the dining room to adjust the thermostat for the whole house

Some Rooms TOO Hot…
Other Rooms TOO Cold?

The Solution is Zoning

Are you tired of some rooms being too cold while others are too hot? Do you find yourself constantly fiddling with the thermostat, space heaters and fans? You wouldn’t have one light switch for your entire house, why have one thermostat?

Zoning offers the easy, affordable, economical solution. Zoning is simply a way of dividing your home into areas with similar heating and cooling requirement, with each zone being controlled by its own thermostat.

Every home has at least two zones; the living area and sleeping area, which are seldom used at the same time. Others are typically divided between upstairs and downstairs; master and kid’s bedrooms, formal living room, dining room, family room and kitchen. Each area is often occupied at different times and has different heating and cooling loads. The result is total comfort, no matter where you are inside your home.

Energy Savings You Can Bank On!
When combined with programmable thermostats, Zoning allows you to conserve energy, up to 30% which can add up to hundreds of dollars in savings per year.

How Does Zoning Work?
Each zone in your home has dampers in your ductwork that open or shut based on your heating/cooling requirements. These dampers are controlled through the thermostat for that particular zone. When you don’t need to condition the air, you save energy because the dampers close the ductwork in that zone of your house. If you combine your system with automatic setback thermostats, you’ll save even more money because you can program each thermostat to automatically provide different temperatures during various times of the day. This truly provides the temperature you want… where you want it… when you want it.
Zone Control Frequently Asked Questions

What is a zone control system?
It is a system of more than one thermostat, electrically connected to a control panel which operates a number of dampers in your forced air heating/cooling system. Conditioned air is then distributed to various parts of your home as needed.

What are the major components of a zone control system?
Control panel, thermostats and dampers used in conjunction with your existing forced air system.

What are the primary benefits of a zone control system?
Comfort, convenience, and energy savings. The system maintains various desired temperatures throughout your home, thereby eliminating the need for constantly resetting your thermostat. Energy savings are accomplished by reducing the energy requirements to seldom used areas of the home; a zone system ensures that only the necessary amount of energy is used throughout the home.

Why does the fan continue to run after the thermostat stops calling?
The system fan may continue to run, after a heating or cooling call has satisfied for two reasons. 1) The fan switch on a thermostat may be set to the “Fan On” position for continuous blower operation. 2) Most systems on the market have a fixed fan purge after a heating and cooling call. The fan purge designed to expel any remaining conditioned air into the living space.

Who would install a zone control system?
Typically 2-story homes with large square footage. A representative from Buschur’s Refrigeration can help you determine if a zone system is right for you.

What is the most popular “size” zone control system?
Usually two to four zones, depending on the home’s floor plan which may tend to form separate areas. For example, a single-story home with a master bedroom on one end, living area in the center and a family room in a separate wing. Or a two-story home with two or more distinct zones such as an “attic” room or room over the garage, or a two-story with multiple roof lines. A tri-level home is another popular design which may contain a lower level “bonus” room which is ideally suited for zone control.

Can zone control be installed in an existing home?
Yes it can. A representative from Buschur’s Refrigeration can help to determine the best way to accomplish this.

Is there any service required with a zone control system?
No. If you buy a reputable brand with a published warranty from Buschur’s Refrigeration, you can expect many years of trouble-free performance. Only changes in living habits might require adjustments from time to time.

Is there an advantage to installing a zone control system in the home as it is being built?
Yes. It is much easier to run wiring through open framework and between floors, therefore resulting in substantial savings in installation costs. In addition, required ductwork sizing and system balancing are also easier and less expensive to accomplish while the home is under construction.


Proper Duct Design & Sizing

Every home is different… specific calculations must be made for each installation. A “Manual J” heat load calculation will be figured according to the construction of your home, insulation, window area, and other heat or cooling factors. We will compute the exact needs of your installation in order to give you maximum performance with the lowest possible operating cost.

Requirements will also be calculated for accurate sizing of the air distribution system for each room to assure constant temperature and humidity control and comfort. Heat loss, heat gain, or cooling load will be weighed with accurate, tested measurements so that the right amount of air at the proper temperature and humidity level reaches all rooms.

Undersizing
Undersized equipment often leads to inadequate heat or cooling so severe that rooms are either too warm or too cold. Unit life may be shortened because the equipment is operating at maximum capacity continuously.

Oversizing
Oversizing leads to long on and off periods then sudden blasts of hot or cold air with inconsistent room temperature and humidity levels. Cost of operation is high and frequent service bills possible.

Accurate Sizing
Comfortable temperature and humidity levels are constant, reducing operating and service costs, and increasing the life of the unit.


Thermal Board

Toughgard® Duct Board with Enhanced Surface
