The AC company said it wasn't big enough to do the entire 8 zones at once but if we went larger you are wasting $$$ having a system that is typically larger than you need to efficiently cool to your requirements. Having said that you can open every zone and it does cool the entire house, particularly if you just run zones in the areas you are in to remove the heat load first then open the remaining zones. If you take your plans to several AC companies you should get a feel for what is required. I got several quotes. Most quoted for a 16kw system (based on their own calcs) one quoted for a 20kw system that in hindsight would have cost us significantly more to purchase and run over time. There is a sweet spot for initial cost and running and it is not wise to just think that bigger is better, but it definitely sounds like yours is on the small size for the size of the house. Thanks ! That’s helpful. I’ll probably be looking at at least 6 to 8 zones too . So something that can handle the load of them all running at once would be ideal, although it would be quite rare that we would hav them all running except for maybe times when I have people over on either extremely hot or cold days . But I’ll definitely contact some ac companies and get a feel for what would be the minimum size unit we would need . Not sure if that works?
