It Can Get Warm Fairly Quickly
We had a 45+ year-old air conditioning furnace that was in place and seemed to work fine when we moved into our house five years ago. Long story short, the furnace was working/functioning but our air conditioner had not been functioning properly since November 2015. We didn’t think much of it since it was the winter months and the A/C wasn’t needed anyway. But, come the new year and just living in southern California, it can get warm fairly quickly.
