During the cold days winter it's nice to get cozy by the fireplace or curl up under a warm blanket.. or in the summer you might find yourself standing in front of the air conditioner vents or a fan for a little relief from the heat.   Is this because it's just not possible for your entire home to be comfortable?  It may be because you are concerned with the energy use or $$ being spent to keep the home cool/warm OR it may be that certain areas of your home just never seem to be comfortable.  If one or more rooms in your home seem to ALWAYS be outside your "comfort zone", Ecojay's SmartZone may be able to help.  Directing airflow (heat/cool) to the rooms that you want, can make rooms in your home comfortable when you want them to be.

Home comfort hack: Could ZONE CONTROL improve your home's indoor climate?

homeowners, Zone Control Infozoning supplyComment

Installing zone control in your home allows you to add thermostats to several areas (rooms) so temperature can be controlled throughout the house.  Most homes have only a single thermostat located in a "central" area.  This means the temperature of the whole house is determined at this one spot.  With zone control, temperature is measured and controlled in each zone for more comfort everywhere.

There are many reasons that zone control might be desirable (or even necessary). 

  • Homes with two stories where the upstairs is regularly warmer than downstairs during the winter can benefit from zone control.  
  • If a house has a fireplace that causes some areas of the home to get too cold when a fire is burning, zone control can help balance the temperature and keep those cold areas warm. 
  • Bonus rooms or unused bedrooms can be turned off with zone control when not in use.
  • Computer rooms or grow areas that need to be a different (more consistent) temperature than the rest of the house.

Zone control can balance temperatures to  create a comfortable living space throughout your home or create different temperatures throughout a building for varying needs.

Zoned climate control in your car… why not your home?

dual climate control

For many years, lots of car manufacturers have been putting separate passenger/driver/rear climate controls in cars.  In such a small space, this could be seen a “silly” feature because the passenger & driver are in very close quarters.  In most homes, however, heating and air conditioning systems still tend to have only ONE climate zone (one thermostat).  Dual or multiple climate zones for a home makes much more since than in a car but is not nearly as often implemented.  With SmartZone most existing heating & air conditioning equipment can be upgraded to have multiple climate controls (thermostats) in different areas.  You could have a thermostat in the kitchen, bedroom and living room… comfort everywhere.  Additionally, with SmartZone, areas that are not being used can be turned OFF to save energy.  All the parts you need shipped for free from ZoningSupply.com Zoning experts standing by to answer any questions you have or help with system design.

Zoning Return on Investment – Payback?

There is no short answer to this question with Zone Control.  Energy CAN be saved with zoning but it is also capable of increasing the comfort of a home.  Because of this, a zoning system can both save and cost energy depending on how the homeowner uses it.  User habits of operating the system primarily determine how much energy will be used or saved.
