Zoned HVAC System

Zoned HVAC systems help keep your family comfortable and also help with efficiency.

Often, homeowners have to deal with uneven temperatures in different rooms of the house. This happens due to the positioning and layout of the home. For example, rooms at the top, attics, etc. often seem to be warmer than other rooms, while those on the lower grounds, like basements, end up much colder. Moreover, different members of the family could have different temperature preferences. For example, someone complains that the HVAC does not cool enough, while another family member simply ‘freezes’ when the conditioning is on.

These are common concerns with a traditional HVAC setup when one uniform temperature setting heats or cools the entire home. Customizing the temperature according to everyone’s need, or trying to ensure that the whole house is equally warm or cool can turn into a thermostat war, often reducing the efficiency of the HVAC.

At times, homeowners turn to quick-fixes like closing vents in rooms where the temperatures are unequal or where the different temperature is desired. Such quick-fixes can cause disturbances in the airflow of the HVAC reducing its efficiency.

Zoned HVAC Systems

Zoned HVAC setups eliminate the inability of traditional HVAC systems to provide customized conditioning. They use electronically controlled dampers and thermostats that help redirect and regulate airflow to specific areas or zones in the home.

Zoned HVAC systems are a great option for almost all types of homes. However, the best results, including energy and cost savings are seen with homes that have one or more of the following features:

  • High ceilings with open layouts
  • Areas and rooms that are seldom used
  • Garage rooms with lofts above them
  • Huge wall windows, or large windows
  • Rooms with more exposure to natural sunlight
  • Sunrooms
  • Multi-level homes
  • Basement garages or basement rooms
  • Open kitchens


Zoned HVACs allow customizations according to the frequency of use of the rooms in the house as well as according to desired temperatures. They take into consideration a number of factors that affect the cooling of a home-like shading, ceiling types, fans, heating appliances, cooking areas, rooms with more or less sunlight, etc. Each zone has duct dampers that can be regulated with its own thermostat.


Zoned HVACs offer energy efficiency as well as cost-efficiency. Zoned HVACs allow HVAC owners to use the AC as and when needed, in whichever room they are, as opposed to running the HVAC in the entire home. Energy efficient HVAC systems prove to be cost-effective too, as they enable up to 30% savings on utility bills.

Increased Comfort

With customized temperatures in different zones in the house, usage of the HVAC set according to the usage of the rooms, reduction in utility expenses, and energy use, HVAC owners can experience more comfort than with a traditional HVAC system.

In addition, technological enhancements such as wall mounted thermostats in each zone, remote controlled thermostats for changing temperature, humidity and fan speeds, add to the comfort.


Zoned HVAC systems also provide the flexibility of installation as a separate project and traditional HVACs can be retrofitted or converted into zoned HVACs as well. Installation and remodeling a traditional HVAC into a zoned HVAC is best done by a trained and professional St. Louis HVAC technician.
