In the War Over the Thermostat, Zoning is the Clear Winner

By Alix Penning

Zoned temperature control has been popular in office buildings, hotels, and businesses for years. Recently there has been steady growth in the number of people using zoned HVAC systems in their homes, and it’s easy to see why. A properly zoned HVAC system saves money, is better for the planet, gives you better air quality, and is more comfortable than a home with a traditional central air conditioning system.

A traditional system blows air through all the ducts at once, sending hot or cool air to every room in your home until the main thermostat reports that the temperature request has been fulfilled. A zoned system uses little doors in the ducts called dampers to channel forced air to the room that requested a temperature change. The dampers open and close, directing the air to the room that needs it and bypassing the parts of the house that don’t. This is all controlled by individual controls which communicate with a central system that controls the dampers and activates heating or cooling.

Save Money

Utility bills can drop up to 30% when a properly zoned system is installed. Controlling the temperature in just one room as opposed to the entire house is a big part of that, but it’s not all of it. Many ducting systems lose air and temperature through inefficiencies like leaks and improper insulation. Zoning decreases loss from your duct system by using less of the ducting, which reduces the wear and tear of the ductwork.

Save the Planet

By heating and cooling only the rooms that are needed, you’re saving energy over a home with traditional central air. You’re also reducing the amount of waste that ends up in landfills, since the ducting in your zoned system won’t need repairs as frequently. This is especially true in two-story homes, which usually need more cooling upstairs and more heating downstairs.

Breathe Easier

Keep dust, pet hair and dander, mold, and other debris from spreading around. Using a zoned system prevents allergens and irritants from traveling around your home. So, dog hair doesn’t end up in rooms the dog isn’t allowed into, and the kids’ bedrooms don’t supply the entire house with dust.

Be More Comfortable

Do you have a room in your home that’s always hotter than the rest of the house? Does someone in your family always run a little colder than the rest of you? With a zoned home you can tailor each room’s temperature individually, and avoid arguments about whether it’s too hot, too cold, or if someone should put on a sweater. Even better, with many Wi-Fi thermostats you can control everything from your computer, tablet, or other personal device. No debating about who’s going to get up and turn the temperature up or down.

Imagine this: It’s a warm night in the middle of summer, and you’re about to go to bed.

You walk through the house to lock up and take a few seconds to switch off the downstairs lights before you head up to your room. As you walk up the stairs you use your smartphone to turn off the downstairs thermostats, and set your bedroom’s temperature to 70°F.

Before your head hits the pillow, the control panel has closed the dampers downstairs, opened the ones to your bedroom, and turned on the AC system. Your bedroom is now being cooled to your perfect sleeping temperature, and your unoccupied living room is not.

It’s not magic, or a dream. It’s temperature zoning.
