There's also the option to have a mini split attached to whole-home duct work. That's what I was referring to.

Agree fully.

I doubt that a mini has the velocity to use central ductwork.

Now, i think that they are hooking up mini outside units to standard air handlers. That works.

Is current heat source Gas or electric?

edit - i see its gas, i would stick with conventional with gas furnace. electricity prices are too volatile IMHO

My heat pump is dirt cheap to operate compared to regular AC.

Compared to electric heat, yeah.
There is an auxillery elec heat strip that comes on with h pump, when in defrost mode, and when set point and actual temp get far apart, but yeah, overall cheap heat.

A heat pump is slightly more complex than a straight AC but not by much, but there are a few more things that can go wrong with them.

If you are use to gas heat, many find the heat generated by the heat pump not to be quite as comfortable (air temperature exiting supply registers with a heat pump may be in the 90 F range vs 130 F, give or take, with a gas furnace). Do you have have “cheap” natural gas vs electric rates? Low electric rates and high gas rates many will chose to go with a heat pump, but if electric rates are higher and gas rates low, AC with gas furnace is the way to go. In heating mode, you would have to figure the cost per BTU of heat generated with electric vs gas using your current utility rates.

Now there is a 4th option, you can go dual fuel, which is a heat pump coupled with a gas furnace (slight more expensive than the other two replacement options) - at mildly cool temperatures, say down to freezing, you use the heat pump to provide heat, but much colder temperatures, then the gas furnace wiill provide heat. The thermostat will control the function of each.

I have company coming to the house tomorrow to change out my HVAC - I’ve opted to stick with straight AC with gas furnace, which is what I have now.

I was faced with the same exact situation a couple of years ago. I chose to replace the entire system. You are gonna have to do it soon regardless, so you might as well bite the bullet and get some improved efficiency out of the deal. I wouldn’t go with a heat pump though….gas heat all the way.

Check your power company and your gas company for incentives.

Dual Fuel inverter heat pump if you want the best both worlds. Still have the ability to keep your house warm in a freeze blackout with a 2000 watt generator. I've been impressed with the heat output of the Bosch inverter heat pump in the upper 30's stretches we've had this year.
