Remote hvac work

I'm not sure If I'm posting in the right place but I wanted to see if anyone knows of remote hvac jobs or similar? I've been doing hvac/mechanical work for over 15 years and I've been searching of programs or training that focuses on either remote tech support and or equipment sales. I had a spine surgery not long ago, and I have a metal plate that goes from under my chin to my collar bone now, and was warned by my surgeon that I will need more spine fusions if i continue the work ive been doing. I've healed and can still do installs and other physically demanding work, but would like to transition to something less physical in the next year or 2. Any advice is greatly appreciated. Thank you
