Removed and replaced 50 ton VAV roof-top units
A pair of 20 year old Trane units replaced on a Saturday, new units powered up 6 hours after shutting the old units down!
Integration with the Siemens Building Automation system, via Trane BacNet option, took longer to sort and commission than actual unit replacements. ps; blue boot covers were removed each time we left the roof to prevent tracking mess into the building.

Harbor East client -
Removal and replacement of a plate-frame heat exchanger:
