Welcome to our Technical Page


Our TAS Ed. HVAC Training Program is Here

We call our new Training Program “TAS Ed. HVAC Training” because helping technicians improve their HVAC knowledge and skills is our focus. Now that we have added Alan Velleman to be our primary phone & field support specialist, Randal can expand our catalog of training classes.

This Fall, along with our regular offering of Fall seminars, we have rolled out a series of FREE Goodman / Amana equipment specific installation & Start-up and Service & Troubleshooting classes to provide contractors and their technicians the information they need to be more knowledgeable and efficient at “Installing and Servicing” Goodman, Amana and Daikin Equipment and right after the New Year we will be offering certified Daikin mini/multi split classes in our Derry location with our live Daikin Units.

While these classes are geared for Goodman/Amana equipment and some information is specific to our equipment, a lot of the information and testing applies to most residential furnaces. We hope you take advantage of this opportunity to get some good training for a great price, FREE! 

Most classes in our catalog can be done at our facility or yours except the Daikin Certified Install & Service Classes and the Amana S Series Installation & Service Classes. If you would like to have Goodman/Amana equipment Installation & Start-up or Service & Troubleshooting classes or some of our other training classes at your companies facility or in our Nashua or Derry classrooms, please call Randal at 1-603-845-1710.



We have a Daikin Mini/Multi Split Installation Class on 1-29 & 30, 2024 from 5 to 9 pm in our Derry, NH Classroom. See flyer for Details.
