Personally I like the free AC.
Once you optimize your job to be close to your home, many of the benefits of wfh disappear.
It seems like a no-brainer to do this in Arizona, but I don't know the economics.
Still need to work out the numbers on the solar panels so I can decide if I should buy them, or lease them.
I live quite frugally otherwise (balking at other numbers in this thread) and $150 per month in climate cost increase for the daytimes sounds perfectly normal to me. During the hot summers I spent twice that when living in an apartment in the big city.
Also consider most people rent and have little ability to impact insulation and efficiency in their homes.
Work from home doesn't mean you have to literally work from home. There are plenty of places you can work from, ranging from free like libraries or parks, to paid like coffee shops and co-working spaces. You can get your employer to pay for the latter.

Those optimizations become liabilities if you get a new job elsewhere.
Alternative framing: your life has been constrained by your career expectation of working in an office; you've optimised around that and found a local maximum.
Work-from-home doesn't remove that local maximum from you, but it creates an opening to find a higher maximum.
