What Are Zoned Air Conditioners and How Do They Work?

Control the temperature of each section in your home with zoned air conditioning. This notable technique utilizes dampers within the ductwork to manage and redirect airflow to specific areas. Unlike central AC systems that only use one thermostat, the zone air conditioning system treats each room differently to provide comfort according to your needs.

When it comes to HVAC zoning and AC repairs, it’s important that you get an expert’s help. AHWA is one of the most trustworthy AC repair companies across Phoenix, Arizona, and other surrounding areas. And to better grasp, this kind of setup, continue reading below.

How Does Zoned Air Conditioning Work?

Before anything else, it’s important to prepare the layout of your home. It should be divided into specific sections, which are called zones. There could be two or more zones, depending on your preferences. Each zone comes with its own thermostat to control the temperature of the area. Meanwhile, each of these thermostats is linked to one primary control panel.

Now that you understand the relevance of creating zones, it’s time to learn more about the damper, which serves as the instrument to regulate air volume and steer it to a specific section. This movable plate is a pivotal component when it comes to air conditioning zoning because it maintains airflow in different zones. It is placed inside the ducts to easily respond to air requirements in a particular area, opening and closing as needed.

On the other hand, if you have a ductless system rather than a central AC system, then the dampers will be set at the air outlet or air handlers instead. Often, these are attached to the walls to provide an easy connection to the outdoor pump. And with the refrigerant lines, the air navigates through the walls.

With the air handlers’ location, dampers can easily open. Using the built-in thermostat, each works independently to provide air according to the zone’s call. When the area reaches its desired coolness level, the dampers immediately close.

What are the Factors to Consider?

There are several things to take into account for zoned air conditioning. While a trained HVAC personnel is ideally the best person to plan this out, it’s important that you have an idea of the key features and components beforehand.

Below are the relevant factors to consider in advance:

  • The square footage of your home
  • The number of zones and how each section is laid out
  • The placement and size of the windows
  • The insulation capacity of the home

After assessing these vital aspects, you also need to evaluate the parts used for zoning air conditioning. These are broken down as follows:

● Indoor unit – Serving as the main air conditioning system, the indoor unit is generally placed in the roof cavity. As the primary component, it holds other vital parts such as the heat exchange coil, filters, fans, and remote thermostat.

● Outdoor unit – Located outside, this unit works hand in hand with the indoor system, driving refrigerant between these two units. Additionally, it is tasked to discard the heat acquired from the indoor section. In comparison, the indoor unit carries the compressor as well as the heat exchange coil and fan.

● Vent – The vents are responsible for delivering air to a particular zone. It passes through the ceiling, maintaining the air pressure in your home while also filtering out dust and debris. This comes in various styles, depending on the design that fits your home.

●  Control unit – Moving forward, the control unit manages the entire air conditioning system. In general, this wall-mounted unit controller is centrally located. The zone controller, on the other hand, is responsible for monitoring and regulating the scheduled air conditioning unit as well as the zones.

Most advanced systems come with their own controls for easy access. On top of that, these high-end control units allow you to manage the temperature at your fingertips via smartphones and tablets.

● Sensors – Measuring the temperature of the zones, sensors aim to regulate the cooling levels of a certain area in your home. To effectively manage the temperature, there are specific types of sensors used. These include sensors for pressure, humidity, and air quality, occupancy, among others.

● Dampers – also called zone motors, dampers generally control the amount of airflow that enters a zone. This valve-like component is also utilized to break off the central air conditioning to a vacant area in your home.

● Zones – Aside from the primary parts, it’s also important to evaluate the zones covered by the system. And as mentioned earlier, plotting a layout of the zones in advance is a vital step in zoned air conditioners. This way, you get to maximize the space as well as enjoy the maximum benefits of zoned air distribution.

What are the Benefits?

Talking about zone air conditioning, there are several advantages when you zone the HVAC system.

1. Better performance, especially for second-story house

In terms of efficiency, zoned HVAC is pretty much more efficient in cooling. This setup is widely utilized to avoid uneven temperatures in the home. Hot spots are often caused because there is only one unit that controls the system. By dividing your home into zones and adding necessary zoning components, airflow is not restricted to only one location.

2. Lesser energy

Did you know that zone air conditioning uses less energy than a central unit? Compared to having only one central thermostat, a zoned HVAC system only utilizes energy that is needed by a specific area. You can easily control the temperature of a specific section, hence lesser energy than having to cool the entire home. Once the area reaches the desired temperature, the air handler maintains the condition.

3. Lesser utility bills

With lesser energy, this also signifies lesser utility expenses. Save money on electric bills by only using the thermostat of a specific zone and shutting off areas that aren’t needed to be cooled.

4. Customized cooling temperature

More than its energy efficiency and extra savings, zoned air conditioners offer better control of the cooling aspect of your home. It provides extra comfort because of the multiple thermostats, allowing you to manage the temperature of each area according to your preferences. So, if you want everyone to be satisfied, let them regulate the airflow as well as the cooling sensation on their own by setting up a zoned air conditioning system.
