Taco After Dark

Commercial HVAC Hydronic Series

Taco Comfort Solutions’ popular Taco After Dark program returns with a commercial HVAC hydronic twist! The Commercial training team, Rich Medairos and Brett Zerba, will host a 3-week commercial HVAC hydronic focused program beginning on June 23rd. This 3-week session promises to be highly interactive, highly informative and, like the residential-focused ones, highly fun.

The Taco After Dark sessions run one hour each and will start promptly at 7:00PM EST. The dates for this 3-week program are Wednesday, June 23rd, June 30th and July 14th. We are taking the week of July 4th off and going to the beach. Your host Rich and Brett will share with you all you need to know about HVAC hydronic pump curves, pump selection, Taco’s Project Builder, Expansion Tank Sizing and Selection and introduce you to the award-winning Hydronic System Solutions (HSS) software. The duo will remain online after the program to answer as many questions about commercial HVAC hydronics as the audience wishes. We look forward to seeing you there!

Taco Comfort Solutions is thrilled to bring its innovative and popular training series Taco After Dark back for the Commercial HVAC Hydronic Series. In the midst of lockdowns, quarantines, and social distancing, Taco would like to help you use this time to sharpen your skills. Together we are offering our full-day commerical training class to you, one hour at a time.

This Taco After Dark session is an energetic, informative and entertaining 3-week program and features practical, real world solutions to the challenges hydronics professionals face every day. And as the program’s name suggests, Taco After Dark is designed for the working man or woman with evening sessions that won’t interfere with the demands of heating season.

Attendees may register for each session individually, and each program will be recorded and archived for repeated viewing. Each session qualifies you for one PDH credit. YOU MUST ATTEND THE LIVE WEBINAR SESSION (NOT THE RECORDED SESSION) IN ORDER TO RECEIVE YOUR PDH CERTIFICATE. The link to the PDH certificate, along with a link to the recorded webinar session, will be emailed to you approximately 24 hours after the end of each webinar session.
