Zoned heating and cooling for a big house

My beach house is over three thoUSAnd square feet and divided into a lot of smaller rooms.

I live in a area of the country where the weather is tepid and overly humid in the Summer and seriously frosty and snowy in the winter.

Attempting to keep a comfortable indoor temperature all year round is challenging and fancy. We need both a oil furnace and an a/c and the more than 2 units run most of the time. The ductwork is installed behind the walls and ceilings and affixs to more than 2 vents located in every room. For the first few years both of us lived in the house, both of us had one temperature control located in the residing room. To make fluctuations to the setting, both of us had to manually adjust the dial. Any raising or lowering of the temperature affected every room in the house. While the residing room was constantly perfectly comfortable, there were certain areas that tended to feel warm and others were chilly. We were also heating and cooling quite a few unoccupied rooms. The oil furnace and a/c were laboring way harder than necessary! Our weekly energy bills were way too high. Hoping to reduce costs and lessen wear and tear on the heating and cooling equipment, I looked into the update to zoned control. The cost of it wasn’t nearly as high as I expected. The replacement process was far less involved than I anticipated. I hired a local Heating and A/C supplier who implemented a series of valves into the duct system to direct the conditioned air to certain rooms. He added separate temperature controls into each room. These smart temperature controls allow access through an app on my smartphone. I’m able to customize temperature settings with a tap of my finger.
