What is a Zoned HVAC System?
How Does Zoning Work?
The better way to set up a zoned HVAC system is with ductless mini-split units. These units come in a variety of styles and models, but basically, it’s a rectangular heating and cooling unit that is mounted high on the wall (or into the ceiling). That’s actually the first part, the indoor air-handling unit (evaporator). It’s hooked up to the second part, an outdoor compressor/condenser. Several of the indoor units can be hooked up to one outdoor unit. Each indoor unit is controlled with its own thermostat.
Reasons Why You Might Want a Zoned HVAC System
1. To solve the multi-level home heating/cooling problem (described above).
2. To balance the temperature in homes where one side of the house gets more solar heat than the other side.
3. To heat/cool only the parts of the home in use. (Why heat/cool a huge house if you’re mostly only using a few rooms?)
4. To get heating/cooling in new house additions / separate buildings without installing ductwork.
