I am looking at heating and cooling options.

[pinballlooking]

I have a 2100 sqft house single floor outside Greenville SC it is about 12 years old. We currently have AC with gas heat. I put in 12.5 kW solar and I am looking at some options to use some elect for heating.

My AC is 4 ton single stage 11 seer about 12 years old not one service call in that time.
My gas heat is 92.6 efficiency they are both Goodman the air handler runs at one speed. Gas heat has run flawless for 12 years.

I have a guy that will put in whatever system I get and let me share in the work he is HVAC certified. He charges me a fair price.

I have 8 acres so geothermal is an option. My neighbor has a small excavator than he will work with me on renting it or give me a good price on digging the horizontal loop.
I have a tractor with a blade and I can cover up the loops so that saves time and money.
My HVAC guy has installed geothermal and will help me install it.

In the cold winter will geothermal keep up with heating or will in need heat strips?

Could I keep my gas heat but use the geothermal air handler?

The other option is a two stage heat pump or an inverter heat pump. Could I keep my gas heat I have now?

I am not really sure what way would be better. I work from home so we use heat and AC 24/7 all year.

I even considered a mini split system but I think my house has to many rooms and we have 2 kids that need conditioned rooms.

I ended up installing 3 single head mini splits and one duel head unit.
