A video of the 2023 York TCD2B and 1994 Lennox HS19 condensing units at work. The Lennox is out of commission due to a major leak. Since it's March and still too cool out, I wasn't able to demonstrate the York, but I found some old footage of the Lennox starting and running from 2022.

The York is a 5-ton single stage unit with the dreaded LG scroll compressor and microchannel coil. Model TCD2B60S31SA, Serial C2C3489683, manufactured in Mexico. Installed July 2023.

The Lennox is a 3-ton (?) single stage unit with a Bristol reciprocating compressor. It was manufactured in 1994, but wasn't installed until later (around 1997) according to a coworker. Model HS19-413-6Y, Serial 5894A28511.

Both units use three-phase power.
