Turned on my large AC unit yesterday for the first time in 2018, and it had a rough time starting up as the fan didn't want to move. As soon as it did I heard that dreadful, distinctive sound of bad bearings. Super loud and grindy. It happens to me with almost every modern unit, I rarely get two seasons out of them. I ALWAYS get the longest third party warranty they offer, in this case a 5 year in home repair warranty where if they can't fix it, they deliver and install a new unit at no charge (I just bought this motherfucker in 2016). The warranty was almost half the cost of the ac unit, but totally worth it, dude already had to come out last summer to take it apart and vacuum it out, something us mere mortals can't do or it voids the warranty. A tech is coming today, so I had to move trays of clones into the grow space and shop vac up all leaves, and make sure all grow related stuff is put away. Always stress and drama when repair people are scheduled to come over, but that is the grow life in an illegal State. The tech is going to turn it on for 30 seconds and declare it fucked, then order a new one for me. They can't simply take my word for it and need a tech to confirm, I'm a mere mortal. Sigh...
