I truthfully don’t suppose what our sister was thinking; she tried installing her own Heating, Ventilation plus A/C system. Well, she absolutely didn’t do a horrible task until she was connecting the line sets with the ductless mini chop system. She didn’t connect the linesets slender enough and her system started leaking refrigerant. She ended up having to call an Heating, Ventilation plus A/C professional to fix the leak and clean up the spilled refrigerant as best as possible. It’s harshly dangerous to labor around spilled refrigerant, refrigerant poisoning can send you to the hospital and be life threatening. If our sister would have just let the Heating, Ventilation plus A/C professionals install her new Heating, Ventilation plus A/C system in the first site, she wouldn’t have been at risk. She says it was just a deranged mistake not to tighten the line sets well enough before charging the refrigerant. That was another issue I had, she used an auto refrigerant kit with an adapter to charge refrigerant to her system. She had a gauge and everything however it was while she was charging the refrigerant when she figured out there was a leak. It was clear that when she was refilling the refrigerant, the gauge was indicating that the refrigerant was lowering, so there was absolutely a leak, then fortunately, the Heating, Ventilation plus A/C professional was able to take care of the leak and the system was toiling great after everything was finished. It was absolutely a easy fix, however still dangerous! I’m just cheerful there are no more troubles with her Heating, Ventilation plus A/C system though, however I do have to supply her some props for doing most of the labor on her own.
