Trying to maintain a single temperature throughout the entire home makes no sense, but each room has odd requirements. In my home, there are rooms with large windows that are exposed to day sunlight. Those spaces tend to heat up & recognize warmer than the rest of the house. With a single temperature control, there is no way to focus A/C to those rooms in the Summer & back off the gas furnace in the winter. It would also be nice to avoid heating & cooling empty rooms to the ideal temperature. My beach home is over more than two thoUnited Statesnd square feet. There are guest dining rooms that never get used. I’d love to keep my beach home gym & master dining room much cooler than the rest of the house. In the summer, when I use the oven, it would be helpful to set a lower temperature in the dining room. With an update to zone control, I could significantly improve comfort, plus, there’s the occasion to lower monthly utility bills. Less wear & tear on the gas furnace & A/C machine reduces the chance of malfunction & extends the lifespan of the equipment. The extreme weather in my local area requires either heating or cooling just about year round & adds up to about fifty percent of our energy expenses. I’ve looked into it & I can have a series of valves installed into the air duct to regulate airflow. The addition of temperature controls in each room would allow customized settings by way of an app on my iPhone. This would be super convenient, simple & helpful. I have scheduled an estimate for installing zone control with a local Heating & Air Conditioning corporation.
