I was recently in a household where their multi split a/c was completely out of commission.
As an Heating, Ventilation, and A/C serviceman, there are particular things I expect to see in a a/c or furnace, however this multi split a/c was mission so numerous parts that I could hardly guess it. After inquiring, I found out that the Heating, Ventilation, and A/C shoppers had noticed the multi split a/c having issues and decided to be their own Heating, Ventilation, and A/C serviceman. They went to the cooling and heating contractor and purchased some heating and cooling device for sale. After finishing at the cooling and heating business, they went back household to their multi split a/c and started taking out the original parts and replacing them with Heating, Ventilation, and A/C parts they purchased from the cooling and heating business. These Heating, Ventilation, and A/C shoppers started watching a/c self help videos in an attempt to repair their multi split a/c on their own. They made one major mistake but, instead of watching videos on how to repair a multi split a/c, they mistakenly watched videos on fixing mini split a/cs. This is why the inside of their multi spit a/c was so messed up. They had replaced numerous of the normal a/c parts with the wrong ones. The most surprising part about this is that the a/c unit still worked a little! In all my years as a cooling expert, I have never to this afternoon seen anything like this messed up multi split a/c with mini split a/c parts
