Heat pump conversion
I'm very new to this community but I feel this might be the best place for some quality wisdom.
I recently put solar panels on my home, got PTO in March and it's been great ever since. Electric bill is typically no more than the monthly service charge from our poco. Our 2ton central air unit is working as it should right now but one day it won't and I'd like to go with a dual fuel heat pump when the time comes.
From what I've gathered, I'd like to go with an inverter based system (I really like the idea of the variable speed capabilities). I know there are a lot more variables when it comes to these complex pieces of tech though and that's where I get lost.
For context, I'm a new jersey licensed electrical contractor with 8 years experience in new construction, 4 years in solar and now I focus on residential service work.
I have an 8kw grid tied solar array with an 11.5kw SMA sunny boy smart energy so I can expand my solar production and add a battery in the future
My house is about 1800 ft², 2 stories, 3 bedroom, 2 bath, unfinished basement, brand new windows, 2x4 walls
ps we're also redoing the kitchen right now, I was planning on keeping the nest thermostat in the basement and using the remote sensor for the nest upstairs. but if that isn't a common solution for smart heat pump systems I would gladly run the required wiring up to the second floor now. iirc 18/6 is what I've seen but really unsure
