Air conditioner suggestions

It's funny you bring this up because I was debating on making a video on air conditioning your grow room. Long story short, you may be better off continuing using central AC. Let me explain my recent experience with this... In my house, I have an upstairs zone for my central AC. That zone consists of 4 bedrooms - one of them is my grow room. I assumed that I was wasting more energy cooling the entire zone vs just my grow room so I purchased a 8,000 BTU portable air conditioner. The plan was to run my central AC less and the portable AC will cool my grow room. I should save $ since I'm only cooling one room instead of 4, right? Wrong. The portable AC pulls 800 watts when cooling and 80-100 watts with just the fan on (when the AC isn't running the fan within still runs). My portable AC increased by electricity bill by 20+ kWh each day! So not only am I spending more $ by running a portable AC, but I found out I still needed to run my central AC almost as much since it becomes uncomfortable in that zone if I don't run it as much as I did. Oh, and I can't forget to factor in the $300 I spent on the portable AC unit. Anyways, I returned my portable AC, got my $300 back, and have a lower electricity bill now. The only positive thing from having the portable AC is my temps were a little more stable. Although, I personally don't feel the additional cost is worth it. One more thing to mention.. Portable AC units suck out the humidity in the air so if you live in a dry environment like me, it will cause your humidity level to drop. If you live in a very humid climate, it may be a benefit since it will help lower the humidity. This is just my experience with it. A portable AC may work better for you in your environment then it does in mine.
