I was quoted 12-14k for new central heat and air which included all the duct work.

I'm in northern Indiana and had a very efficient heat pump/central AC unit and when the outside temp got below about 40 degrees I had to use my forced air furnace as backup because the heat pump couldn't extract very much heat from the outside air to bring inside temp up and keep it comfortable.

And for brand value I'd argue there is no "nike" of PMc, so many can fluff the feathers and cluck how great there brand value is but I say show me the client stream coming purely from brand, I call BS to that "cluck", and say it's open air and opportunity for any to create brand value in a market and take market share where there is any lacking options in PMc quality or availability. 

Something else to consider would be that you already likely have cleaners, handyman services and the like in Orlando area.
