Good Morning.
It was 77 before 6am this morning. Dew point is 73, so it’s steamy, although I haven’t been outside yet. Chance of thunderstorms today, likely tomorrow.
Yesterday was very uncomfortable to work outside. I capture the charge in the old condenser and got it disconnected by 8 or so, put the forks on the tractor and moved it around to the front by the lane. Brought the new condenser around back. Cleaned the area for the new one, put a bucket on the tractor and went to the stone pile for some 2a to make a level area and set some patio blocks.
By then my buddy arrived and we set the unit in place.
It’s the one on the left. I had the other heat pump running, so it was cool inside where we had to run the line set and mount the inside unit. Put up an easy up canopy for shade over the outside unit to do the wiring and connect the line set.
The old unit was straight AC and ran three inside units, the new one is a heat pump just does one that is upstairs. Originally the heat was from a propane furnace and the mini splits did the AC. About 10 years ago I added a 16 SEER heat pump and relegated the propane to back up duty. The new heat pump is 22 SEER, but only has a head upstairs. The plan is for the new unit to be the main source of heat and AC, with the ducted heat pump as the second stage, and the Propane as the 3rd stage or last resort.
At any rate, not too long after lunch, it was all connected, so we pressure tested the lines with 400 psi of nitrogen. It held pressure and no bubbles at the connections, so purged the nitrogen and evacuated it, it was tight and pulled down to 200 microns. Released the stored charge and fired it up. Wasn’t long until there was a steady stream of condensation.
By the time I put all the tools away I was beat. Today I’ll clean up the rest of the mess inside, and put the music room back together and connect all the stuff I moved to remove the old and install the new.
But that is after breakfast with the professor.
Considering that it will be 95 with a heat index over 100, doing inside chores is a good plan.
