Be ready to go through 1 every 3 years thats my normal time.. I grow ina grow tent in a shed in direct sun -- so my shit is always on, I even need it in winter diring ht eon cycle.
I recomend gettign one that you can also control without a remote, Im jsut glad mine came with 2 remotes, the batteries in the old one coroded because of my clumsiness of spilling water and not wiping it up.
I usually jsut go with whatever walmart model is on sale and that has a drain for the evaporated water.
Ive also had luck picking up portable ac units on craigs list for around 100 (compared to 400-500)
