Thanks for all the info by the way. It was helpful.

There are a lot of variables. But in my opinion, the least expensive way to go, both the initial cost and the life cycle cost, is to buy a single speed HVAC system vs a variable speed system. This may change over time because way more single stage units are sold today than variable speed systems. If variable speed systems become more popular, the cost will come down as it does for almost everything.
