In this video I explore whether or not my mini split heating/cooling system will work when the temperature dips below the listed operating temperature of the condenser. I found that, although it is technically working, it is not performing like you would want. Since mine is in my garage, it is not critical that it heats the space, but if this was in my house, it would be a cold night! Be careful if you are planning to only use mini split heat in cold climates. I hope this was helpful! Thanks for watching!
