As a manager for a Community Action Agency, I direct most staff members towards this course to get a better understanding of ASHRAE requirements within the WAP program

by Mike Devore, Engineering Manager, Greenheck 05/26/2022

Being new to the Ventilation industry, this course provided the knowledge to have meaningful conversations with others more experienced. Also, it brought a real awareness of the health risks caused by stale indoor air and straightforward solutions to improve our quality of life.

by Vernie Hellmann, Weatherization Systems technician/ Energy Auditor , Jefferson Franklin... 02/01/2021

I have been in weatherization for over 2 1/2 yrs and have been designing and installing ventilation systems and i thought i needed to learn more. This was the perfect course for me since i have already been using the free red calc tools. It helped me learn more of the tools that i did not know would be a great help in my work.

by Senai Hagos, Energy Auditor / QA Inspector, DOEE 01/28/2021

I'm very pleased to take this important course. I haven't been doing an Energy Weatherization Audit for few years and it was to the point and refreshing. The website is updated and all those new tools are so awesome. Hopefully, I will make your website too busy for this year and years to come.

by Jaime Soto 09/01/2020

Awesome class learned a lot and found much more information that I needed and clarified lots of questions I had. The online tools are new to me so having them is very helpful. Thank you.

by Cheng Vang, Assessor/Inspector, Fresno Economic Opportunity Commission 08/19/2020

Highly recommended to anyone that works in the weatherization program.

by Jeff Pello 06/17/2020

A very comprehensive and thorough overview of ASHRAE 62.2. I had pretty good understanding of the importance of ventilation and IAQ and this course certainly reinforced that view point and gave me new talking points when interacting with clients. The ASHRAE 62.2 standard was always something I had trouble wrapping my mind around. The way Rick presented the calculations and install strategies in the course will certainly stick with me. His RED tools are also awesome and something I will certainly incorporate into my business.

by Mohammed Hussain, Energy Auditor, Hanac Inc 06/08/2020

You need to know about venting and the right way this is the course to take. You will not regret, all of your question will be answer.

by Keith Bernard, Quality Control Inspector, Hanac Weatherization 05/15/2020

The course is very informative and it shows how much more learning, educating and implementation is needed in the field. Thanks for the direction to the tools available and the resources.

by Lee Newton, Owner, Newton Properties, L.L.C. 03/23/2020

This course was a great way to simplify the seemingly complex and make it understandable! Thanks!

by Larry Fitch III, Housing Specialist , Community Action Allegan 01/07/2020

I enjoyed the flexibility of the course. If i was stuck on one chapter i was able to move onto the next.

by Eric Wheeler, Home Energy Advisor, Opportunity Council 06/29/2019

The information that was new to me was highly relevant and helpful toward my objectives in taking the course. The instructor was quick to reply via the discussion boards and email, and his feedback was always helpful. I know I will be referring back to the course materials in the future as I apply the course to my work in residential energy efficiency.

by Austen Parsons, Housing Services Specialist, Community Action of Allegan 06/26/2019

I thoroughly enjoyed the course! I like being able to take things at my own pace and that's exactly what you can do here. Having to be out in the field outside of training, this online training is more flexible in that I can sit down for an hour or so and make some good progress. The course is readily available to look at and watch again at all times during the training and even for a year after it's finished! This makes it very convenient if I was unclear about a topic or needed something defined again for the work I was doing. Rick Karg was very good in responding to questions asked and added very helpful information to discussions or work submitted.

by Guy Caroselli, Home Performnace Manager, Bradley Mechanical 06/12/2017

I have been involved in this field for over forty years, done over 13,000 audits, fixed over 3,000 homes,trained utility staff and mentored other auditors. The format and content of this course was the best online experience I have taken. Highly endorse and recommend this course for those needing a clear understanding of complicated subject.

by Sydney Lambert, Supervisor, Kalamazoo Michigan Weatherization Program 05/31/2017

I really enjoyed this course. I was able to ask questions and get answers easily.

by Jamie Fereday, Energy Analyst, Sol Coast Consulting & Design 04/03/2017

by Jay Rezendes, Auditor/Inspector, Citizens for Citizens 04/03/2016

I would recommend this course to anyone still confused with Ashrae and Red Calc when Ahsrae began it was a big learning curve for all of us and I think courses like this will help people understand more of how important it is.

by Nathan Farris, Energy Craft 04/03/2016

I recommend this course for anyone who is either professionally interested or obligated to understand and implement the residential ventilation standard developed by the ASHRAE committee.

by David Leatherwood C.E.M, President, Intelepoint LLC 04/01/2016

by Ian Guttridge, Training Manager, Systemair Mfg 03/28/2016

This course is not just for the installer/contractor, I would recommend this course for anyone who is involved in home ventilation. I am in ventilation manufacturing and I learned a lot that will help me and my company in the future.

by Michael Salmon, owner, HRM Group, LLC 03/24/2016

the heatspring method is engaging and worthwhile. instructor was knowledgeable and approachable. excellent investment

by Dave Gross, owner, American Htg Clg Refr Inc 03/21/2016

I have been in the HVAC business for almost 30 years and ventilation was not part of our plan when installing furnaces or air conditioning. We always thought that it was money not well spent but after this class I see we were wrong,


Accessibility to Mr. Karg was immediate. The course was extremely comprehensible. A cornucopia of Ashrae 62.2 venting standards, techniques, equipment and design. A plethora of resources to consider. You will be confident in your knowledge of Ashrae 62.2 after this course.

by Jennifer Bayeur, Weatherization Auditor, Metropolitan Development Council 12/04/2015

Heat Spring makes it easy to learn. Thank you.

by David Watkins, Weatherization Program Coordinator, DuPage County Community Services 12/04/2015

I would highly recommend this course to anyone associated with the building science and home performance fields. Lots to learn here. Well put together.

by Rod Opp, Energy Conservation Program Coorinatoor, Nebraska Energy Office 12/04/2015

I was apprehensive at first, but overall I enjoyed this type of learning experience.

by Curtis Ecklund, Housing Assessor Supervisor, Rural Alaska Community Action Program 12/03/2015

Excellent! Great course. Instructor had a very good understanding of material. Focused on areas of ASHREA that are most practical & people in the industry can apply easily.

I agree with the courses philosopy and the reality that it will be a huge uphill battle to get people to listen.

This is a great introduction or refresher course for the ASHRAE 62.2 standard - The material and instruction provided a deeper understanding of ASHRAE 62.2 and IAQ.

by Brett Young, Housing Assessor, RurAL CAP 12/01/2015

If you want to really learn about the ASHRAE 62.2-2013 Ventilation Standards, then I would definitely recommend taking this course, Rick is a Great Instructor!

by Richard Sevigny, President, owner, Richard R. Sevigny and Associates 11/30/2015

As an architectural engineer, certified energy auditor, and certified general appraiser, I would encourage anybody with similar background and experiences to enroll in this outstanding course. This is cutting edge knowledge from the best individual resources.

by Bradley Wiesneth, Community Services Manager/Weatherization Coordinator, DuPage County ... 11/30/2015

This is the first course I have taken with HeatSpring. I will definitely be looking to see what else they offer in the future. Great Instructor, great information, great course!!!

by Tom Andrews, Owner, Andrews Home Energy Services, LLC 11/27/2015

This course really "drilled down" into the ASHRAE 62.2-2013 code in regards to how and why it is important. It is more than just getting moisture out of the bathrooms.

by John Simpson, WX Manager, Rural Cap 11/26/2015

I would highly recommend this course to any body who has used ASRAE calculations in the past or present. I wish I had the opportunity to take this course a decade ago as it explains things very clearly. Thank you, John Simpson; started out is temp WX worker and now manager for Anchorage and Juneau WX programs. Wow how 20 years can fly by :)

by Jonathan Pierson, Housing Assessor, Rural CAP 11/18/2015

by Mark Lyman, Weatherization Manager, Rural Alaska Community Action Program 11/12/2015

This course was excellent, a real wake up call to the dynamics and importance of ventilation. Mark Lyman

by Tim Ecklund, BPI QCI & Building Analyst, Rural Cap 11/03/2015

I definitely know more about ASHRAE6.2 2013 than I did before I took the class but more importantly I appreciate the reasoning behind the standard. ASHRAE is the minimum but not necessarily best practice.
