As a homeowner, you rely heavily on your HVAC systems. The quality of your heating, cooling, and ventilation and the performance of the units that control them largely determine your comfort and efficiency levels. Because HVAC is such an integral part of your home, there’s no reason to have anything less than the best.

For many homeowners, an HVAC zoning system is the top option. However, not everyone has heard of a zoning system or understands how it differs from others. We’re here to help.

As your trusted and experienced HVAC contractor in Canton, Green Energy Mechanical Inc. knows exactly what it takes to ensure better home functions. We’ll explain what a zoning system is and how it can benefit your and your entire building.

Unzoned vs. Zoned HVAC System

Unzoned HVAC systems utilize a singular thermostat to control the temperature of the entire home. When you set the thermostat, the system will send air through ducts into each room to heat and cool the home to the same temperature.

On the other hand, an HVAC zoning system can accommodate multiple different temperature preferences within the same home. It typically utilizes multiple thermostats, often either in each room or on each floor. 

How an HVAC Zoned System Works

But how exactly does the zoning system work? Let’s say, for example, that a home has four family members in separate rooms, and their temperature preferences vary—two are comfortable with the current temperature, and two want their rooms cooler. The zoning system can make it happen.

Each person sets their thermostat to their desired temperature. The air conditioner will then send cool air throughout the ducts. Dampers within the ducts will open and close, sending cool air to the two indicated rooms and blocking cool air from entering the other two. 

Main Benefits of an HVAC Zoning System: Comfort and Efficiency

An HVAC zoning system may be the practical choice for your building. It can benefit you and your home in two main areas: comfort and efficiency. 

Increase Individual Comfort

The obvious benefit of an HVAC zoning system is that it can increase the comfort of every individual in your home. This is especially true if family members have different heating and cooling preferences. The zoning system will allow everyone to customize temperatures to suit their needs, providing consistent comfort throughout the year.

Maximize Whole-Home Efficiency

Likely the less obvious of the two main benefits is the HVAC zoning system’s ability to maximize the energy efficiency of your entire home. With an unzoned system, you have no choice but to heat or cool the entire home at the same time, even if certain rooms aren’t in use. For example, if your family is gathered in the living room during winter and you want to stay cozy, you’ll need to waste energy heating the entire home.

Because you can choose which room or rooms you want to heat or cool, an HVAC zoning system produces significant energy savings. You’ll have a more efficient home and see a decline in your monthly utility bills. 

Is an HVAC Zoning System the Right Choice For Your Home?

An HVAC zoning system is the best solution for more comfort and efficiency for many types of homes and families. Some situations for which you might want to consider zoned cooling and heating include:

  • You have family members in separate rooms that have different temperature preferences
  • You have a multi-story home
  • Your attic doubles as a living space
  • You have a basement that you want to keep at a different temperature than the main floor
  • Your home has several large windows that affect indoor temperature 
  • You have a room over the garage
  • There’s a sunroom in your home

Of course, HVAC zoning systems aren’t right for everyone. If you have a single-story home, a small floor plan, or each member of your family has similar temperature preferences, then the zoning system may not result in significant energy savings. If you’re not sure whether zoning is the ideal choice, have an HVAC professional inspect your home and provide their option.
