I’ve been very happy with this MRCOOL 36,000 BTU

Nicholas Dryden · June 2026

I wasn't sure what to expect at first, but this system has been great for my home. It cools every room well, starts quickly, and doesn't make much noise. My house feels comfortable all day, and I like that it doesn't seem to use as much power as my old unit. I'm really glad I decided to buy it.
