Work from home today. A/C guys coming to install a new system. Took about half the day. Around lunch time I was getting a bit uncomfortable and couldn't even work effectively. I can't imagine how uncomfortable it must be in the attic.
New system on and blowing. The outside unit is much quieter, the inside unit is also pretty quiet, but the air it is blowing is strong and loud. Must be pumping a larger volume of air.
