Comments on Ref Tools for Android

★★★★★ chordarrow1 · Sep 12, 2022

Taking an HVAC course to certify as an HVAC tech and this app already began helping me glide into the industry's discipline. Very useful tool.

★★★★★ Thomas Mallinger · Jun 4, 2022

Super cool app. All the industrial refrigeration techs I work with have it. It's a lot easier than carrying around different PT charts in your wallet. Also has manuals and documentation on all Danfoss products so if you run into an ICAD or EKC controller and don't know parameters you can access then through here.

★★★★★ Kraig Kimbrell · Nov 18, 2024

Great Application No more ziplock bags full of PT chart

★★★★★ Ryan Bonigut · Mar 18, 2024

Very handy lookup for T&P for lots of different refrigerants. Even has glide details and so on.

★★★★★ nambwinya matukuta · Jun 3, 2023

It's good app for air conditioner technician to know the level of gas and gas used to your machine

★★★★★ Rómer Z Avendano · Jun 27, 2022

The app is amazing 👏 However, I am looking for R441A, and it does not show that refrigerant data. It would be great to have it.

★☆☆☆☆ Mario Z. · Jul 9, 2023

The only reason I don't give it a better rating is because it doesn't have Greek as a language

★☆☆☆☆ Petrus Allen · Sep 30, 2025

Not about the app’s it about updating everything Time why every month

★☆☆☆☆ si thu · Aug 3, 2023

I can't download by cell phone, what's wrong.
