Mobile Auto ac

I notice patterns. Seeing alot of 2020 and later model year cars using the newer r1234yf refrigerant needing recharge and or repairs. Higher rate of early compressor failures or what I consider to be early for the mileage im seeing. And amd always condenser damage leading to a leak as well. But thats been common for a long time.
Www.mobileautoac.com before the hest returns so you can stay cool this summer

So really good ac day today, may be a little sun burned atm. But alot of people seem to make appointments and never show, or not cancel or reschedule.
What should a small business do with that? Thinking of making a back up list for when im booked up and out on the weekend to give someone else a chance and getting that time slot..
