I submitted the report and the team responded to me directly with each report. The first time was due to me entering the incorrect model number and there even gave me the correct model none I was looking for so I could retry my search. The second time was truly equipment they didn’t have their database, not only did they email me all the info personally, they added it to their database by the end of the next day so it was searchable. I’m in several online forums and groups with other HVAC professionals, when someone asks about equipment I always share screenshots from this app and every time I get asked to share the link to this app by other techs…. It’s been well worth the money! I would like to see future updates include links to documents such as instillation manuals and tech support numbers. **Developer response:** Thank you for taking time to review the app and for sharing the app on other forums. I will keep in mind your request for links to installation manuals. Right now lots of data updates as manufacture prepare for new refrigerants to meet the EPA regulations. So adding features will have to wait a while. ### 5/5 — Fantastic app!!! *2023-11-26* Whether you are in sales or a tech, this is a fantastic app that will give you essential information such as blower tonnage and manufacture date.

They have 95% of the info you need and if it’s not in there you can email it to them and they were personally find the info for you if they can. This is easily worth the $10. **Developer response:** Thank you for the great review! I am working on that other 5%. ### 5/5 — A must have app *2023-07-26* I am a residential HVAC estimator and having this app in my pocket makes it so much easier to know what’s already in a customers home. The devs are very responsive, if something is missing and you request it to be added you generally hear back within 48 hours. Well worth the little money paid. **Developer response:** Thank you for the great review! The program is really good at residential equipment and it helps to show the age of the existing equipment to homeowners to let them know it time for replacement. Lots of my customer think their system is only 8-10 years old then I show them their system is over 15 years old, make the sale a lot easier. ### 5/5 — Great app. *2023-06-07* Great app for field techs and sales reps. Not perfect but the best thing out there. It keeps getting better with time. **Developer response:** Thank you for taking time to give a positive review.

I'll keep it for myself. but I would like more information about each unit, so that it would be enough to enter the model and get the most complete information about the device. rather than search different websites. Thank you. **Developer response:** Thank you for taking the time to review the app. We are constantly adding more data to the data base and updating the application about ever two-three months. We are looking into creating a repo of documents on our website that decoder app can link to via the model number. We have to make sure this repo conforms to copyrights laws before proceeding.

Having this information off hand helps your sales (so it will pay for itself 100x over), and it has an easy to read layout, as well as an export feature. Top marks to the developer! To the developer: Your response to a recent review is what made me confident enough to buy it. It showed that you are still engaged. Top marks on design, execution, and simplicity. Suggestion?
