Constantly changing the HVAC unit

As of recently, I have been changing my HVAC temperatures a lot.

While my family and I like normal and steady temperatures, since we have been having guests over, I have been changing the HVAC thermostat and raising the cooling temperatures.

It seems like a lot of guests like the house to be cooler, but my family likes our house to be much warmer, so this causes a few issues, and a few heated debates between my wife and I. Even my kids have been complaining recently. This is why I have been searching the internet for possible solutions, and I think I might have found one. I’ve been doing a lot of reading into zone controlled heating and cooling systems, and they sound like the perfect solution to our problem. A zone controlled A/C basically allows you to customize your different temperatures for different rooms, instead of the same temperature throughout the entire house. Since my business relies on having constant guests at my home, I really think this could benefit my family and I. I planned on discussing this with my wife, because the cost is pretty high, but it’s either that or we deal with a chilly house. The only other option is maybe a mini split ductless A/C for the guests, but I have a feeling that would be less efficient, which is why I believe that a zone controlled HVAC is the best of both worlds, since the guests can still be in a nice cool and professional house, but my family and I don’t have to suffer in a chilly house.
