Definitely worth adding to your app collection as it is another valuable tool at your disposal. ### 5/5 — Best HVAC app. *2021-10-17, version 3.30.2* Spending too much time on social media while you wait for that pressure test? Why not learn a little bit while you wait. This app is great and eons better than a Facebook HVAC group. ### 5/5 — Best HVAC app *2021-10-12, version 3.30.2* I don’t post much in this forum but I have found this app very useful with the amount of knowledge from all the technicians on this app I have learned a ton. I read through this app almost every evening when I get home from work just to see how much more information I can get and usually I learn something new in the HVAC and boiler field. And in the resource tab is a wealth of information if you are having an issue with something you will definitely get an answer either in the resource tab or on your post from another technician that may have run into the same problem. I am glad this app is available as I have followed HVAC know it all from the days on Facebook. ### 5/5 — Technical community and support in social media from. *2021-10-12, version 3.30.2* Since this app was created it has greatly helped me to stay sharp in the hvac field. And if I ever needed help there’s always someone out there with the experience to help guide me through troubleshooting. ### 5/5 — Best App for HVAC Professionals *2021-10-12, version 3.30.2* This is the only place I’ve found that has helpful conversations for people in the industry. Every other group on Facebook or LinkedIn or elsewhere have 50 joke comments and then two that answer the question that was asked. It is a helpful community that wants to build everyone in the trade up. I use this every day now. ### 5/5 — Best HVAC resource out there! *2021-10-10, version 3.30.2* It’s a super positive collection of industry professionals. From students to veterans. Residential to industrial. There is not a day that I don’t learn something new on there. As someone new to the service side of things this has been an absolutely invaluable resource. Thanks for bringing this together, Gary.👍 ### 5/5 — AMAZING *2021-10-10, version 3.30.2* there’s actually technicians that will help you and advise you on all sort of equipment. very helpful. ### 5/5 — Great place to learn *2021-10-10, version 3.30.2* I just graduated from HVAC/R school this year. I have asked many questions and been given great feedback from the experienced techs. Everyone is willing to share knowledge and pass on tricks of the trade. ### 5/5 — Awesome APP *2021-10-10, version 3.30.2* This app is a must have for the newbie to the seasoned technician. The professionalism and willingness to teach on this app is second to none. No question is considered stupid and no one ridicules you if your not sure of wrong about something you post. Only help and encouragement from these professionals on this app. For $10 bucks a year you can’t go wrong. I can’t say enough about the value of this app. Do your self a favor and download this now!! ### 5/5 — New to the trade! *2021-10-10, version 3.30.2* I’ve been working and learning HVAC for 1 1/2 years and I love this app! Lots of good information and stuff! ### 5/5 — HVACR *2021-10-07, version 3.30.2* I love this app not only do I look to this app for confidence and direction, I love the camaraderie. ### 5/5 — Awesome *2021-09-03, version 3.30.2* Great app for newer technicians wanting to learn from more experienced technicians. Just joined and loving it can’t say enough good things about it. ## Most critical reviews (10 lowest-rated) ### 1/5 — Nope *2024-10-19, version 4.34.1* You have to pay before even knowing what’s in the app ### 1/5 — Scam - forced to pay before testing *2024-06-30, version 4.34.1* The app forces you to make an account and pay (per month or year) before gaining access. You can’t even see if the app is worth it. From my experience, an app that makes you pay first must not be confident you’ll love the app. ### 1/5 — Requires a membership *2023-02-22, version 3.30.2* I absolutely despise apps in which they have made it free for download, and they go around spreading word about their app on various places on the internet. Once you get to download the app, you are met with a create account option, fairly normal, and then to even access the app you must pay a subscription fee. This should definitely be made clear beforehand and not deceive people by posting a pictures in the preview which make it seem like a free open community app. Maybe that’s why this hasn’t taken off ### 1/5 — Forced to pay *2023-01-12, version 3.30.2* App forces to pay upfront to take a look inside. While theres nothing interesting inside, few posts in a month. Waste of time and money ### 1/5 — Suspect App Ratings *2022-12-20, version 3.30.2* Part1 I won’t pay to try out your app, I have done this in the past for other apps then I had to wait around for a refund. Part2 The ratings are extremely suspect!! Every 5 star review is over a year old and the way each review is worded are similar with each other also another issue are the user names for the reviews. Definitely seems like another app developer paid for 5 star reviews to deceive us. ### 1/5 — Cost $$$ to join *2022-03-11, version 3.30.2* App description conveniently leaves out that they charge a monthly fee just to use the app. The app doesn’t mention this until after you've entered your information ### 1/5 — Free use? *2021-07-05, version 3.30.2* Apparently, they want you to commit to payment prior to “free” use. I guess you have to go through the hassle of cancelling before the second week if you don’t find it useful. Thanks, but no thanks. ### 1/5 — Just a chat room! *2021-04-02, version 3.30.2* You have to be kidding! This is just a chat room! Not for engineers! ### 5/5 — Excellent App! *2025-04-11, version 4.52.2* I have been following this content creator on YouTube for a while. I am glad to be part of this awesome community. ### 5/5 — Fantastic opportunity to disrupt air condition *2025-02-09, version 4.52.2* Knowledge is the most important component of being a quality service technician. In order to be successful as a business owner, you must also know where to find the answers. The HVAC Know It All app is a game changer. ## Most praised reviews (8 highest-rated) ### 5/5 — Great Community *2025-02-07, version 4.52.2* Just a bunch of awesome people in the trades sharing knowledge and supporting each other. ### 5/5 — The must join community for HVAC R tradespeople! *2025-02-07, version 4.52.2* If you get FOMO you should probably just join. Don’t be cheap it’s free. Great content almost everyday! If you know you know! Mic drop! ### 5/5 — It is *2025-01-27, version 4.52.2* Great ### 5/5 — Ok *2024-05-16, version 4.34.1* I work in residential I would love it learn more if only the residential group posted more ### 5/5 — Big help. *2023-01-18, version 3.30.2* This app has been a god send as I’m learning the trade. There’s no judgment, no one is rude, the environment is perfect for growth. Thank you so much for this. ### 5/5 — Amazing tool *2022-07-26, version 3.30.2* This HVAC app has helped me in so many ways as a HVAC tech. I’ve only been a tech for 10 years and learn something new every day from other professionals. Able to see other ways of doing things, some better some worse ha but you see so many things you never would think of. I live in Southwest Nebraska and we are in a little bubble here so only know what we see and are taught, but with this resource I have learned more than I thought I could from a simple app. Keep HVACing! ### 5/5 — HVAC *2022-04-12, version 3.30.2* Great app and info is good to ### 5/5 — Great App for Tradesmen *2022-03-02, version 3.30.2* This is a great app for tradesmen (particularly HVAC/R). There is a wealth of knowledge in the group with no hesitation to help someone out when they need it. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
