For me, it is about stress and time (and money). I hate to say this because I don't want to upset anyone (really just trying to help, not perfect), but we created HomeSpark.AI to try to reduce the stress/time/money blackhole from personal experience. What my contractor was doing didn't feel right, so I had to hire a "auditor" of sorts who wrote a 47 page report of the issues. Didn't relief the stress but did relieve the uncertainty. Then I said that has to be an easier way with AI. I just ran into this issue with an oil pressure gauge for my whole house generator. The AI gave me the part, video and where to buy/cost for part. $30 and 20 minutes later installed - before that I had no idea other than call a guy. Sorry not trying to shill anything , just hope to be helpful.
