Listen to the old folks
You know how the older folks will keep telling you to stick to mitsubishi and the more established brands? Just do it. Prism is a fraud. I got my system 3 installed in Nov 2025, and less than a month later, the compressor was leaking water onto the unit below me. I requested for prism to rectify this and they state it is normal. My previous compressor didn't leak, the 4 units of compressors above my unit doesn't leak. I'll say it's normal for their compressors. Unless you want headaches and frustration, just stick to the more established brands
