5 Things You Must Know While Choosing The Best Automotive AC Gauges

1. AC Gauge Size

When shopping for automotive AC gauges, be sure to consider the size of the gauge. Some gauges are very large and may not fit well in some vehicles. Conversely, some gauges are very small and may be difficult to read. Choose a gauge that is the right size for your vehicle.

2. AC Gauge Type

There are several types of automotive AC gauges available on the market. Each type has its own benefits and drawbacks. Some of the most common types of AC gauges include mechanical gauges, electric gauges, and digital gauges. Mechanical gauges use a needle to indicate the level of refrigerant in the system, while electric gauges use some type of lighting to indicate the level of refrigerant in the system. Digital gauges use numbers or words to indicate the level of refrigerant in the system.

3. Gauge Accuracy

Before buying automotive AC gauges, be sure that you get an accurate reading of your car’s AC levels. If you pay hundreds or thousands for professional services to recharge your car’s AC system and they find that there is no refrigerant left, then spend more money on tools with high degrees of accuracy so you won’t have to go through this process again. Accurate readings will save both time and money.

4. Auto Repair Shop Use

If you are hoping to buy automotive AC gauges for use in a shop, make sure that the gauges you choose can be used in this way. Some automotive AC gauges are only useful for one-time use, so they do not meet the needs of professional automotive repair shops. Shop owners need to be able to rely on their tools for accuracy and consistency. If your shop only performs occasional AC system checks, then purchasing automotive AC gauges is probably not worth it.

5. The Coolant’s Makeup

Before buying automotive AC gauges, consider what type of refrigerant your car uses to cool its air conditioner system. Many newer cars use R134a refrigerant because it does not deplete the ozone layer like other heavy-duty gases used in vehicles before it. However, many older vehicles still use R12 and R22, which must be recharged with oil-based additives. If you want to recharge your car’s AC system yourself, then consider purchasing automotive AC gauges that are compatible with the type of refrigerant in your vehicle’s air conditioner system.

Why Do You Need Automotive AC Gauges

1. Maintain Proper Temperature

One main reason for having an automotive AC gauge is to help ensure that your car or truck’s air conditioner is running at optimum performance levels. A faulty air conditioner can leave you feeling extremely uncomfortable while driving around town on a hot day. By keeping an eye on your automotive AC gauge, you can be proactive about addressing any potential issues with your AC system before they become bigger problems.

2. Save Money on Gas

When your car’s air conditioner is running at full capacity, it consumes more fuel than when it is turned off. If you have an automotive AC gauge, you can monitor how much power your AC system is using and make adjustments as necessary to help save on gas costs.

3. Keep Your Interior Cleaner

One of the lesser-known benefits of having an automotive AC gauge is that it can help keep your car’s interior cleaner. When the AC system is running, it pulls in air and circulates it throughout the vehicle. This helps to eliminate any odors that may be present inside the car and also helps to keep the interior surfaces clean.

Wrapping Up

With so many automotive AC gauges on the market, it can be hard to know where to start. That’s why we created this comprehensive list of our favorite products!
