This video shows how to set up AC diagnosis for the first time:

AC Diagnosis is an innovative Internet of Things (IoT) sensor at the forefront of diagnostic technology. It attaches to your car's central vent and allows users to determine whether their car is cooling efficiently. The diagnostic tool takes into account all outside weather conditions, temperature and humidity, calculates the optimal vent temperature, and communicates if the air conditioning is working properly (or not).

If the sensor doesn't show up please check the GPS/Location setting on your phone. The GPS/Location on your phone MUST be ON to connect the AC diagnosis sensor. If the GPS/Location is on and the sensor still doesn't show up please check the battery.

In this video, the founder of AC diagnosis, Marco Bonifaccino, explains how to diagnose the car air conditioner issue with AC diagnosis Smart sensor.

AC diagnosis gives back control to every car owner. Modern cars have become quite complex and they contain more technology than ever. If you are testing your car’s air conditioning performance without taking the outside weather conditions into account, it can be easy to misread the real A/C performance of your system. One of two things could happen: You might take your car to a mechanic and pay for a professional service even though it still works properly. The A/C system is not working as efficiently as it could but you don’t know that, which also means you are losing money at the pump because you are filling up more often. The AC diagnosis sensor takes into account all outside weather conditions, calculates the optimal vent temperature, and communicates if the air conditioning is working properly (or not). It does all of this in just a few minutes. This way you gain more transparency and control over your car, enabling you to save money and time, and giving you peace of mind.

Yes, you can test the car’s air conditioner that uses refrigerant R-1234yf. Go to “Settings” on the AC diagnosis app and select the type of A/C system you want to test the performance.

This video shows how to get started with AC diagnosis Snart Performance Sensor.

AC diagnosis works with all types of AC systems and vents and it is compatible with 2 types of refrigerant, R-1234yf and R-134a. All new cars coming off the assembly line today have R-1234yf refrigerant running through their air conditioning system. However, there are several models that still use R-134a.

AC diagnosis is available on our website https://www.acdiagnosis.com/

AC diagnosis mobile app is available for iOS and Android devices on the App Store and Google Play. Visit: www.acdiagnosis.com/getting-started, download the app, and get started on keeping your air conditioning working efficiently.

Yes, you can save the record any time you test your Air Conditioning. AC diagnosis app allows you to track: diagnosis result, temperature, humidity, air conditioning or car model, and add a note.

Yes, you can edit the saved records.

AC diagnosis is power by a CR2031 battery. The battery can be replaced when it’s over. If the battery is charged AC diagnosis sensor can work up to 5 years. The battery duration for the sensor varies depending on how often it is used. The mobile app provides the battery level.

Yes, you can use the tablet. Download the AC diagnosis app on your tablet and login with the same email you use on your smartphone. All the setting, include the test results, will be keep into your account.

Please, check your phone setting. When texts and numbers are very big on your phone, you might have set up a larger "display size". To read perfectly the diagnosis information the display size should be set up as "default". Follow the instuction below to change the setting on your phone: - Androis smartphone: Font size & display size - iOS smartphone: Change the font size on your iPhone, iPad, and iPod touch

AC Diagnosis is an innovative Internet of Things (IoT) sensor at the forefront of diagnostic technology. It attaches to your car's central vent and allows users to determine whether their car is cooling efficiently. The diagnostic tool takes into account all outside weather conditions, temperature and humidity, calculates the optimal vent temperature, and communicates if the air conditioning is working properly (or not). Thermometers (which have been around since 1714) only measure the overall temperature of your car's central vent, which can lead to an inaccurate reading causing unnecessary work and expenditure. This happens because warm air can blow through your AC when the outside temperature is hot and impact the performance of your air conditioning, even if your car's air conditioning system is in perfect working order.
