What is a 2 zone HVAC system?
a Dual-Unit System. With a zoned system, one unit provides heating and cooling to multiple areas of your home. In a dual-unit system, you have two totally separate units that each operate a single zone with separate, unconnected thermostats.
Are dampers bad for HVAC?
HVAC dampers control the amount of air that flows through a section of duct work. When a HVAC damper goes bad, proper airflow is no longer achieved through the duct work. You may end up with too little or too much airflow through the duct.
Is it easy to install dampers?
A damper can control the flow of air in your ducts, changing the output to different levels of your home or different rooms as needed. However, it is not too difficult to install an inline damper, and below are some step-by-step instructions you can follow to add one yourself.
How long do zone dampers last?
Dampers can last around 20 years with proper maintenance.
Can you install a second thermostat?
You can help make a more evenly conditioned home by installing a separate thermostat in another part of the house. When two thermostats are wired to a heating or cooling system with a zone control and dampers installed in the ductwork, you have true separate temperature zones in your home.
How much does a 2 zone HVAC system cost?
HVAC Zoning System Cost
| Number of Zones | New Construction | Existing Home |
|---|---|---|
| Two Zones | $1,500 to $1,850 | $2,000 to $2,500 |
| Three Zones | $1,850 to $2,100 | $2,200 to $2,850 |
| Four Zones | $2,000 to $2,500 | $2,650 to $3,300 |
| Additional Zones | $225 to $350 per zone | $335 to $500 per zone |
How much does it cost to add a zone to HVAC?
Conditioning one room or zone comes at a significantly different price than heating and cooling an entire home with eight or more zones. Generally, new HVAC zoning equipment can range in cost from under $3,000 for a one-room cooling option up to $15,000 or more for multiple zone heating and cooling systems.
Do I need a zone controller?
Your home probably needs a zone system if: It has more than one level. Its foundation is a concrete slab. There are furnished rooms in the basement or attic.
Do all HVAC have dampers?
Typically in most homes, your HVAC dampers are located in the main supply trunks. Some homes have no dampers at all. Hopefully most homes have a damper in each one of the supply ducts. Your home may have a supply duct go to the right and you might have one go to the left off of your furnace.
How do zone dampers work?
The control panel regulates various temperatures in the house by activating dampers in the HVAC system. These dampers work like a valve system — opening and closing the air flow to your zones. Once the desired temperature is reached in that zone, the thermostat will alert the dampers to close and stop the air flow.
How often should dampers be replaced?
Dampers do not need to be replaced unless they are non-functional. It is crucial when determining the need to replace damper actuators, that parts are carefully inspected. Per the International Building Code, a damper should be tested at the time of commissioning, and again tested one year following the installation.
Can 2 thermostats work together?
You can put 2 thermostats on the same line and it would work but it would be kind of dangerous if one was flipped into cool mode and the other left in heating mode. It would also be a bit useless because you would have one thermostat dominating for the whole house.
Can 2 thermostats control 1 zone?
Thermostats in zoned systems can control the same heating and cooling system or each thermostat can control its own system. When multiple thermostats control one system, the house is divided into zones using dumpers in the duct work throughout the house.
Is zoned HVAC worth it?

Do I need two thermostats for two zones?
Sometimes, low voltage heating systems are broken up into multiple zones (through duplication of heat sources, or usage of dampers and ducts). Each of those circuits will require their own dedicated thermostat. If this is the case, we would recommend a separate learning thermostat for each zone.
Where are my HVAC dampers?
Go into your basement or attic and find the dampers. Usually, they are positioned somewhere in the “take-offs” or “branches” of the duct system. With manual-type dampers, they have either a rod that you can adjust using a screwdriver or a lever that you can turn by hand.
