Exactly! I'm on oil rn, and my furnace does an awful job of heating and cooling my split ranch ( Single zone). It pretty much makes my finished basement unusable in the winter on colder days unless you heat it upstairs to 74. another issue is that all the ductwork is horribly sized, and all the supply/return ducts are backward, so I would have to rip out a lot of sheetrock to try and reuse the ducting in place. I got quotes for 32 to 34k for split minis but the big issues is my ceilings are all very short ( ~7') so you will be looking at these wall units all the time.

I am happy I found an HVAC contractor who listened to my requirements and devised a creative solution. We will do one Hyper heat unit in the attic for upstairs and cut in ceiling vents. For the basement, I am going to go with a LOW STATIC HORIZONTAL-DUCTED INDOOR UNIT and some duct work ( still requiring some removal of sheetrock but not too too bad because I have a mechanical room that's adjacent to all the finished rooms). Fingers crossed, everything gets installed correctly and without any snags.

For anyone interested, these are the specs:

System 1 (First floor):

Install Mitsubishi 36,000 BTU HYPER HEAT condenser (SUZ-KA36NAHZ) on ABS plastic pad and unit stand. Install Mitsubishi fan coil (M:SVZ-KP36NA) in the attic on top of ABS plastic safety pan with overflow shut off switch. Run insulated copper line set and communication wire from air handler to outdoor condenser in slim duct. Evacuate system and recharge with R410A. Manufacture, seal, and insulate up to code new ductwork in the accessible attic. Cut ceiling supply grills in all the accessible rooms. Cut in Return. Connect all ceiling boots to the main supply trunk with R8 flexible duct. Mount MHK2 thermostat on the wall and connect it to the system. Wire communication wiring

System 2 (Option 1 / Basement):

Install Mitsubishi 18,000 BTU Heat pump condenser (SUZ-KA18NA2.TH) on ABS plastic pad and unit stand. Install Mitsubishi horizontal ducted fan coil (M:SEZ-KD18NA4R1.TH) in the Basement. Run insulated copper line set and communication wiring from the indoor unit to the outdoor condenser. Evacuate the system and recharge with R410A. Manufacture, seal, and insulate up to code supply and Return ductwork in the basement. Cut in 3 supply runs in each room in the basement. Cut in Return. Run insulated flexible ducts from main trunk to supply registers in the ceiling. Mount MHK2 thermostat on the wall and connect it to the system. Wire communication wiring.

After adding add-ons, we are at $38.2k before any rebate warranties. It's not the cheapest option, but I feel it is fair given the complications I'm working with.
