## What is A/C Pro?

When the time comes to recharge your vehicle’s A/C, the A/C Pro® phone app is here to help you.

Step by step instructions, specifically tailored to your vehicle, guide you through the process. From locating the low side pressure port to letting you know when the recharge is complete, the instructions are seamless and easy to follow.

If you are using an A/C Pro® product with Smartcharge TM technology, the app will connect to the gauge via Bluetooth. The app then provides guided, adaptive, vehicle-specific instructions helping to eliminate guesswork. An integrated troubleshooting guide get back on track should the need arise.

Don’t feel like reading instructions? Alternatively, the app also provides handy instructional videos that are also specific to your vehicle’s year, make and model to help guide you through the recharge process.

Perhaps you just need help in locating the low side port. The app includes access to the low side port finder – a robust image database showing where low side ports reside for most vehicles.

The App also provides access to the A/C spec database, which provides refrigerant and oil specifications and capacities by vehicle.

And if you still need additional help using an A/C Pro® product, the app will connect you directly with our support team.

Thank you for choosing A/C Pro for all of your Auto A/C needs.

### 1/5 — Inaccurate gauge readings

*2026-07-22*

If you are downloading this app, you have already messed up. Return this product immediately and DO NOT use on your vehicle, the pressure will read incorrectly and in my Alice cause overcharging of the system. While it showed in all green on the app, not remotely close to the warning - it still managed to read inaccurately and over pressured. Stick to old fashioned gauges and return this product if you value your AC.

### 1/5 — Doesn’t work at all

*2026-06-30, version 1.1.7*

JSON errors when looking up vehicle.

### 1/5 — My Car Isn’t Included

*2026-06-24, version 1.1.7*

My 1969 Jaguar E-type isn’t included in the car lookup.

### 4/5 — Check the battery of your gauge

*2026-06-21, version 1.1.7*

The app works fine but the Bluetooth gauge itself has issues.

### 1/5 — Smart Gauge frozen

*2026-06-03, version 1.1.7*

The app locks up and Smart Gauge is not accessible.  The app is sending JSON error messages connecting to my login. I never received the message to enter my UPC.  Product is useless.

### 1/5 — App does not work

*2026-06-01, version 1.1.7*

App cannot load the files for any vehicle, it just displays an error, it’s unusable.

### 1/5 — This app is BS

*2026-05-27, version 1.1.7*

The app doesn’t even work. It’s hot as hell outside and all I’ve been trying to do is to get the damn app to even work.

### 1/5 — Junk

*2026-05-27, version 1.1.7*

Got error message every time I attempted to select my car model. I deleted the app. It’s useless.

### 1/5 — Asks too much information

*2026-05-20, version 1.1.7*

This is an app that just shows you videos and pictures for how to do something. Why do you need my location? Why are you asking for access to my photos? It makes no sense. Half the video didn’t load either.

### 2/5 — Clunky app

*2026-05-15, version 1.1.7*

I appreciate the video clips, but the instructions are difficult to read. With all that wasted space on the screen, why not give more room for the instructions. Ridiculous having to scroll to read more than two rows at a time.
