Evelina74 tigerdunes is correct, the refrigerant system is (supposed to be) a closed loop. It does not need additional refrigerant unless it's leaking. It's not just the access to the roof that prevents you from verifying that he added anything, you would need a lot of equipment and know-how and to have checked things before he did any work. But the bottom line is that if a system is low on refrigerant then it's leaking (assuming it was charged properly to start). It's not an acceptable practice just to add some refrigerant -- you have to find and repair the leak. But the other issue is that it's not easy to determine the proper charge on an existing system. Many repair techs just "wing it" and guess because they were never trained to do it correctly. On a system with a TXV (many systems now) the only correct way to determine the correct charge is using the sub-cooling method. Ask your service tech: 1.) how did he determine that it was low? 2.) where was it leaking and how did he fix it? If he answers anything but using the sub-cooling (or superheat if you don't have TXV) method for question 1 then he should not be working on your system at all. If he didn't find a leak and didn't look for a leak then he shouldn't be working on your system at all. I think the answer to both questions in this case will turn out to be, "he shouldn't be working on your system at all". The link below explains the sub-cool method of determining the proper charge on a unit. I don't expect anyone who's not an HVAC person to understand it completely, but I post it so people get that it's more involved than "feeling the pipe and seeing if it's cold" or "I looked at my gauges".

I don't care for frozen fish, but I like chicken filets or fingers. I dip chicken breasts pounded out whole or in strips in seasoned flour, egg and fresh made bread crumbs seasoned with fresh grated parmesan. Freeze on parchment covered trays. When frozen, package in freezer containers or freezer bags.

Mark, Overseas I've seen special outlets that are like power boards in themselves, or you can get those adapters that plug into a double outlet and give you six outlets, designed for low-drain appliances just like you propose. This would be a way perhaps of avoiding code violations since I doubt you could just hang an extra 8 outlets off what's probably supposed to be a dedicated circuit, or you could just provide an extra, dedicated circuit. I like your idea in principle, anyway. In order to calculate the load, which will mostly be small except the computer. printer and coffee maker. The first two will probably be small but the printer might draw a bit if it's a laser. In order to calculate your total load, it's ampsxvolts=watts, but in your case you don't want to use the output voltages you've quoted me, as that doesn't really tell us how much current the adaptors will use. Most will say "120v 150ma" or something similar - a ma is a millampere. I suspect none of the plug packs will add up to very much. If the outlet's in a cabinet - again, check if this is legal, it may be easier and again more legal, to nicely mount a plug-in power board in the cupboard, plugged into the outlet you put in there - that way you can get 8 or 2x4 outlets, without wiring in all those outlets- when you say 6 to 8 do you mean 3 or 4 doubles, or do you really mean 6 to 8 doubles? That's a lot. Make sure heat's not going to be a problem, perhaps if there's going to be an airspace over the cupboard, you could cut a nice ventilation hole at the top and cover it with a grille.

By federal law it should be as simple as asking the company to repair the leak and if they didn't comply,calling EPA. Correct me if I misread EPA regulations. My understanding is failure to correct leaks this size (or asertain improper install or other reason for low charge) subject's service company to fine. One more example of an giant size agency created by government that does absolutly nothing other than create new laws, jab sharp sticks into citizen's sides while selectivly inforcing laws they created.
