What is a Zoning System and Why Would I Want One?

Schedule Now

Upgrading to a indoor temperature variations inevitable. Since heat rises, upstairs rooms are usually naturally warmer. Meanwhile, living spaces downstairs with exterior walls facing away from the sun may be simultaneously chilly. Continuously adjusting the thermostat to maintain a comfortable compromise throughout the whole house often means your HVAC system cycles on and off excessively, adding to wear and tear and decreasing system energy efficiency.

A zoning system divides your home into two or more distinct temperature zones controlled by independent thermostats, without the expense of installing a second furnace and air conditioner. Zoning also allows you to withhold heating and cooling from parts of the house that are unoccupied at certain times of day while still maintaining comfortable temperatures in occupied areas. Studies have shown that energy savings achieved by upgrading to a zoning system range from 15 percent to 29 percent.

Here’s how zoning works in a typical two-zone configuration:

  • Motorized dampers are installed in your HVAC ductwork to control the flow of heated or cooled air into pre-determined zones in the house. The dampers are operated by a central controller that receives signals from independent thermostats located in each zone.
  • In the default position with the system cycled off, all dampers are open. If the thermostat in Zone 1 signals for heat or cooling, the controller closes the appropriate dampers to Zone 2 and conditioned air flows to Zone 1 only. If the Zone 2 thermostat subsequently signals the controller, dampers leading to that zone open as well.
  • As the desired temperature setting at each dedicated thermostat is achieved, dampers leading to that zone are closed and heating or cooling ceases to flow into those rooms. When both zones are at the desired temperature, the furnace or A/C cycles off and all dampers in the system return to the default open position.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
