These guys are great. Solid quoting process and admin follow up. James and Perdomo showed up with all the gear and tools. James and I went over the paperwork, scope, and he took the time to explain those options clearly. They took care to protect surfaces and were clearly efficient in their work—I'm in Operations in a paint contracting company, so I know about these things all too well! They cleaned all ducts, air handler, and grills taking them all outside the building and washing them (they coordinated with building maintenance for that). Then they sealed all boots and the plenum with an antimicrobial coating using a pretty sweet Graco machine (we’ve got a few of those at work!) and also reduced air blower speed to address humidity. Here we are the next morning, a night of cool, clean air and the place looks like there wasn't a moment of interruption. Thank you James and Perdomo, thanks Ductz team. Give them a call!
