Now I do HVAC on offshore drilling rigs and drill ships so I absolutely know what I’m doing but I’ve been listening to these guys podcast for years I can’t tell you how many times theses guys taught me something I never knew I didn’t know. Sometimes it’s some I knew but an easier way of going about it. Great for someone just getting started or not that far from retirement. Without a doubt, the most important thing on my phone. ### 4/5 — Needs Updating *2025-09-28, version 2.2.16* Needs update for A2L ### 5/5 — Check list no longer work *2024-10-15, version 2.2.13* Searched on the website and in the app for a contact us option but couldn’t find one. I can no longer get the checklist to load. Not sure if there’s an issue or if they were purposely deleted but they were extremely helpful. Hoping I get a response and fix to this. Thank you Bryan for everything you do to keep us techs educated! ### 5/5 — Good but checklist problem *2024-10-13, version 2.2.13* Greta app. I love it. However as of 10/12/24 the issue with the checklist not showing up is still a problem. Could this be fixed ? ### 3/5 — Tech Tips Not Working *2024-07-20, version 2.2.3* The screen is blank. If I search for something, I’ll see some articles and such, but nothing is displayed on the Tech Tips screen. I’ve deleted the app and reinstalled with no luck. i-phone 14 with the latest ios. ### 5/5 — Thank you *2024-04-13, version 2.2.1* I am a Maintenance Technician for a Property Management Company during the day and go to a trade school at night for HVAC. I listen to the podcasts and am very grateful for the information and knowledge shared during these podcasts. Very motivating! Thank you! ### 5/5 — Thank you *2024-04-12* I am a Maintenance Technician for a Property Management Company during the day and go to a trade school at night for HVAC. I listen to the podcasts and am very grateful for the information and knowledge shared during these podcasts. Very motivating! Thank you! ### 2/5 — Needs an update NOW *2023-02-25, version 2.0.1* Two stars because the articles are very well written yet I see a review from one year ago claiming the search button does not work. It still does not work. This app has great potential to help a lot of folks out but it needs to be fixed ### 5/5 — LITERALLY THE BEST APP *2022-09-01, version 2.0.1* Been a tech now for a few years. I don’t have the best group of guys to pass down solid knowledge and they tend to cut corners. I found this app and I have been actively reading every post my noggin can handle during my evenings relaxing. Bryan, I love the way you write man! I notice your casual humor 🤣🤣. Every post written by these guys keeps you focused. Not all of us techs are blessed to work with you guys but thanks to technology, we have the ability to learn from you all! Thanks a bunch! ### 5/5 — Very useful to stay current with the trade *2022-08-02, version 2.0.1* Absolutely amazing app, works great even on older phones.
