I may need to get my HVAC unit replace. Don’t know where to begin. Any recommendation on a system that will pair well with solar?

I am also looking at Bosch BOVA60HDN1M20G 4-5 TON HEAT PUMP to replace an ancient two 5 ton ( oversized ) Carrier AC and Furnace system.If you are willing to spend a few $ then I would go for an inverter based system like Bosch or Daikin. I have both and they run super quiet and very efficiently. My Bosch (3 ton) has a 20.5 SEER rating, runs at 56db and the compressor can run as low as 25% output- which means it starts up running on super low (and efficient) to see if it can get the job done, if it needs more power it then increases in 1% increments until it hits the right balance. We installed it and a hybrid water heater (which I hate) at my lake house and our bills are down 75% this year. To be fair a good chunk of that is the WH and we are only there 5-6 days a month but still super impressive (and they replaced 7 year old systems).
Did you find some local Bay area authorized installers for the Bosch heat pump? When I looked up on the Bosch site, I could only find one of the few listed that actually did HVAC, and that one curtly told me the Bosch BOVA/BOVB were very backordered. This was back in the spring though, the supply chain and demand might be quite a bit different now.I am also looking at Bosch BOVA60HDN1M20G 4-5 TON HEAT PUMP to replace an ancient two 5 ton ( oversized ) Carrier AC and Furnace system.
Did your Bosch replaced an existing AC/Furnace and if yes, did you reuse the existing line set ?
How much square feet your Bosch is heating/cooling ?
I am in Bay Area and have a 3375 sq ft two storied 1992 built home with good insulation. I am wondering if two 4-ton or two 3-ton Bosch system will be good - one for each zone ( floor ). I called HVAC contractors for estimating the project , but none are ready to do calculation following any process ( Manual J etc ). I am apprehensive of trusting their guesstimates.
I also couldn't easily get anyone to provide a ManualJ calculation, so I did it myself using the nearly free software from CoolCalc. IIRC, after carrying out the calculation, I paid $10 to allow the calculation to be transferred to a PDF file. When I did this a couple of years ago, the $10 allowed 5 or 10 different scenarios, which was useful because I was considering whether to add insulation. Actually using the software, as well as making the measurements of exterior wall sizes and window sizes, took about me about 5 hours. There is a learning curve for the software. I also spent perhaps 10 hours watching videos and reading up on the calculation before starting.I am also looking at Bosch BOVA60HDN1M20G 4-5 TON HEAT PUMP to replace an ancient two 5 ton ( oversized ) Carrier AC and Furnace system.

I ran across this video recently and it has me really intrigued.

I would want to get a setup that would utilize my existing ducting rather than wall mounted head units, but being able to install additional solar panels (say on a pergola) that are not part of my interconnected system would be so amazing.
In the summer I use a portable AC unit in my office; replacing that with the 12k BTU version and a couple solar panels would further reduce my net grid use.
Yes, it replaced an existing dual fuel AC/furnace. It is installed on my lake house which is roughly 2100ft. They used the existing lineset and ductwork but abandoned the chimney and ran a PVC pipe instead. It does a fantastic job.I am also looking at Bosch BOVA60HDN1M20G 4-5 TON HEAT PUMP to replace an ancient two 5 ton ( oversized ) Carrier AC and Furnace system.
