Thank God! A 5-man hvac crew arrived a little after 9:00 AM, and they drove away in their pickup trucks a few minutes ago: roughly half past Noon. They were friendly, efficient, and cleaned up after themselves very well. I sit here now enjoying cool air blowing through the vents, with a brand new central air unit, a brand new furnace, and a new little wall thermostat.
And the adventure continues.
