Hi I wondered if anyone could offer their opinions on my situation. My dad has an established domestic refrigeration repair business which he has run on his own for over 25 years. He has recently passed away and I am thinking of carrying on the business. He did start to teach me but got too ill to continue. I am wondering how easy it will be to pick up the techinical side? I have worked with vehicle air conditioning and am technically minded. I am researching F gas courses and think this will be a good place to start? it seems a mad opportunity to let go -the phone is still ringing daily and he hasn't worked or advertised for over 2 years. he was the only engineer in the area so there is no real competition. I also wondered about the decline in repairs as the cost of replacing such items is getting ever cheaper? any advice would be greatly appreciated. thanks
