Six rooftop units on one Santa Monica building (CSLB Lic. #952950). The scope on this job: replace the package units and ducting for units 1, 2 and 3, replace the ducting and reconnect units 4, 5 and 6, install drain lines for all six, and seal all the exterior ducting with white duct sealant over the grey. That last line is the one nobody asks about. Duct that leaks gives up conditioned air, and on a roof it gives it up straight to outdoors, so sealant on exterior duct is doing work, not just finishing the look. Free estimate: (818) 390-9943
