compressor will suck out the RH too much. you will never be able to keep control of it. No sense trying to compensate for it. You can get a thermo-electric unit for cheap if you hunt for a scratch and dent. I got a new 28 bottle Newair that had a small dent in the back of it for $140. You cant even tell there is a dent. And it has performed flawlessly for 1 1/2 years now while running 24/7
