I would like opinions about the following, thanks in advance. I don't do this trade for awhile now (my knees are falling) A Carrier Heat Pump - 15 years in good maintenance - was not cooling, everything were working. I suggested the Technician, after 2 hours on and off cooling the compressor with water to check (I don't know what for two hours) that there, in the air handler unit was a TXV. He proceeded to remove the TXV, in doing so, because he only has over sized adjustable wrench, he had to pulled everything out for the wrenches to fit (he didn't have the proper wrenches) and in doing so he damaged the tubing in two places (small/capillary tubing to the evaporator) then he went out for about 2 hours to shop for a Dryer. He returned, installed the dryer and sweat the small openings in the tubing. The unit took awhile for cooling but when we left it was working.
Questions: (1) If the original TXV came with the equipment, was a good decision to remove it? (2) Shouldn't the technician have in the truck a dryer and not take 2 hours looking for? (3) Shouldn't the technician have the proper tools? (4) Shouldn't the technician charge 6 hours for his misdiagnosis? (5) For his butchered work, when in a non delicate way pulled the tubing out? (6) Will this work survive? We already paid, it is not the money, but I recommend this company a lot. I know the owner (he's a Carrier dealer) and never had problem with, but he grows and use now employees, that in my opinion, are practicing with customers money without supervision. I appreciate any inputs. Thanks
