Although standard heating and cooling systems, with one thermostat, are suitable for most residences, the reality is that some homes require different temperature and comfort settings for different areas of the building.

A standard HVAC system doesn’t allow much control. If your home has a standard HVAC system that is losing a lot of energy or simply not meeting the comfort and temperature standards of your home, a zoned heating and cooling system may be right for you.

What is Zoned Heating & Cooling?

Zoned systems have different thermostats for the different zones in the home. If you have different needs for different areas of the home, you will be able to change the settings for just that area only. By only heating or cooling the areas that you are occupying, you can will increase your energy savings and comfort.

Zones can be as big or small as you want, however, you should always consult a professional HVAC technician for the most efficient setup. It’s a delicate balance between what you need and what you want.

For example, if you wanted to have a separate heating and cooling setting for the upstairs bedrooms, a zoned system would allow you to keep the upstairs at a more efficient temperature when there is no one occupying that space.

How Does Zoned Heating & Cooling Work?

You may be wondering how this is all accomplished? Do you need separate heat pumps for each of your zones?

Well, it’s a lot simpler than you may think. When installed properly, a zoned heating and cooling system will be able to control temperatures in different areas of the home. It does this by controlling the dampers in your ductwork that leads to different zones. This option is usually best for homes with a healthy duct system in place.

But that’s the not only way to install a zoned heating and cooling system. Besides controlling the air flow in your ductwork, it is also possible to install a zoned HVAC system using ductless mini-split HVAC units that are installed into separate areas. Each ductless mini-split unit controls a different area of the home.

This is accomplished by having a condenser (heat pump) installed on the outside of the home, which is then connected to an indoor mini-split air handler inside the home. Additional indoor air handlers can be added to the various “zones” in the home. Sometimes additional heat pumps are necessary.

Benefits of Ductless Mini-Splits

1. Cost-Effective

Many times, ductless mini-splits are the best financial option for renovation work. Ductless zoning is great for when adding additional ductwork would be difficult and expensive. Additionally, the SEER (seasonal energy efficiency ratio) is almost always higher on ductless units, up to 26 SEER.

2. Quiet

No more noisy startups or bangs and clacks in your ductwork. Ductless units are quiet and unassuming.

3. Sleek and Attractive

Ductless mini-split are a lot smaller and most people prefer the way they look. There are even units that can run flush with the wall or ceiling to camouflage it even more. As zoned heating and cooling gets more popular, newer, fancier units will be brought to market so you can choose the exact look and feel for your new HVAC system.

In addition to increasing comfort and control, zoning systems also provide precise information about the current temperature and humidity levels in that zone.

Whether you go with duct zoning or ductless zoning, zoned HVAC system can provide massive energy savings. Depending on a variety of factors, including how large your house is and where it is located, ductless heating and cooling might be perfect for your home!
