So... how does the Ultra-zone system work?

Each thermostat can turn the heating and cooling system on and off. If any one of these thermostats calls for heating or cooling, the Ultra-Zone system opens the motorized damper for that area and directs all the heated or cooled air to that location.

Installing zoning systems

The technicians at Tri-County HVAC are experienced at installing zoning systems in homes and commercial settings. We will make recommendations for zoning areas and explain the process of installing the motorized damper system and thermostats.

Zoning recommendations

  • Most homes needs a minimum of 2 zones-the living areas and sleeping areas
  • Adding more zones for the family room or kitchen will add comfort and energy savings
  • Part-time rooms like the basement and guest room can be turned off unless needed
  • The baby's room will have a different comfort level than rest of the family


Did you know you can save up to 30% or more on your energy costs by zoning?

Tri-County HVAC Save on Energy CostsMany people don't realize how much energy they're wasting when they have 1 thermostat controlling their entire house. Keeping every room at the same temperature usually means someone is too cold or too warm. Zoning is the answer to keeping everyone comfortable and it saves money.

What is zoning?

Zoning divides your home into areas with common heating and cooling requirements. Each zone is controlled by its own thermostat so you can set the temperature in each "zone" differently to make sure everyone is comfortable. Unoccupied areas can even be turned off to save more money on energy cost.

Tri-County HVAC uses the Ultra-Zone system by EWC Controls to provide personalized comfort for Portland area homes and businesses. Think about it - you don't have 1 light switch to control all the lights in your home so why should you only have 1 thermostat. Zoning solves the problem of cold basements and over-heated bedrooms.
