The purpose of this quiz is to test your basic knowlege of A/C systems.

• 1.

Our couplers only fit on one port. This port can be found by following the larger diameter aluminum line as it runs from the back of the compressor toward the vehicles firewall. Which port is it?

• A.

High Side

• B.

Low Side

• C.

Service Port

B. Low Side
Explanation
Always use the Low Side Port to add refrigerant. NEVER attempt to add refrigerant from the High Side Port

When using a gauge it's important to know the outside temperature and set the dial correctly. This is because:

• A.

As temperatures go up, system pressures rise.

• B.

As temperatures go up, system pressures drops.

• C.

As temperatures go up, high side rises and low side drops.

A. As temperatures go up, system pressures rise.
Explanation
When using a gauge, it is important to know the outside temperature and set the dial correctly because as temperatures increase, the system pressures also rise. This means that the pressure within the system will increase as the temperature increases. Therefore, it is crucial to adjust the gauge dial accordingly to accurately measure and monitor the system pressure.

Rate this question:

• 3.

Gauges are important for which of following reasons?

• A.

As a diagnostic tool, to make sure refrigerant is the problem

• B.

Prevents overcharging, which also leads to warmer air

• C.

I'll take both a and b Alex

C. I'll take both a and b Alex
Explanation
You should always encourage your customer to use a gauge when recharging their A/C. By using a gauge the customer is less likely to overfill the system.

Rate this question:

• 4.

A customer comes back into the store complaining that the needle on the gauge went straight to red when they attached it to the car. What should you do first?

• A.

You have the best return policy out there,so you take it back without questions

• B.

You tell them something is seriously wrong and recommend a good mechanic

• C.

You ask if the car is running with the ac set to max cool. You need the compressor to be working to get an accurate reading. If it's not, then you recommend a shop

C. You ask if the car is running with the ac set to max cool. You need the compressor to be working to get an accurate reading. If it's not, then you recommend a shop
Explanation
The correct answer is to ask if the car is running with the AC set to max cool. This is because the AC compressor needs to be working in order to get an accurate reading on the gauge. If the compressor is not working, it could cause the needle on the gauge to go straight to red. In this case, it would be recommended to take the car to a shop to have it checked by a professional mechanic.

Rate this question:

• 5.

A customer comes back into the store complaining that needle on the gauge is bouncing between the colored zones. They're confused, so you tell them:

• A.

The system is broken and you need a shop

• B.

The compressor is cycling on and off. This is normal for some cars. Wait until the compressor comes on and take the reading.

• C.

The compressor is cycling. This is normal for some cars. Wait until the compressor is off and take a reading

B. The compressor is cycling on and off. This is normal for some cars. Wait until the compressor comes on and take the reading.
• 6.

A customer comes into your store and grabs the cheapest can of straight gas and brings it to your counter. you should:

• A.

Ring him up. He looks like he knows a thing or two about cars.

• B.

Tell him that his system has a leak and show him A/C Pro with a gauge. It's good for the more common rubber leaks and the gauge will help you to know the proper charge level.

• C.

Recommend a good mechanic because his system is leaking and can't be repaired without one.

B. Tell him that his system has a leak and show him A/C Pro with a gauge. It's good for the more common rubber leaks and the gauge will help you to know the proper charge level.
Explanation
The correct answer is to tell him that his system has a leak and show him A/C Pro with a gauge. This is because the customer has chosen the cheapest can of straight gas, which indicates that he may not be aware of the potential issues with his car's A/C system. By informing him about the leak and recommending A/C Pro with a gauge, the customer can address the problem and ensure the proper charge level. This solution is more practical and helpful compared to simply ringing him up or suggesting a mechanic without any explanation.

Rate this question:

• 7.

A customer wants to know the difference between super seal and the other leak sealer products. you tell them:

• A.

It's super!

• B.

It seals rubber and small metal leaks that take two weeks or more to drain a system.

• C.

It only does rubber like the other products, it just more concentrated.

B. It seals rubber and small metal leaks that take two weeks or more to drain a system.
Explanation
The correct answer explains that super seal is capable of sealing both rubber and small metal leaks that take a significant amount of time (two weeks or more) to drain a system. This sets it apart from other leak sealer products, which may only be effective on rubber leaks or may not have the same level of concentration.

Rate this question:

• 8.

A customer comes in and wants to know how many cans of refrigerant they need for their system. You should:

• A.

Look up the make and model in your system. It should tell you how much it will hold. If it's not there, call IDQ Techline.

• B.

Sell them a vent thermometer and add refrigerant until the system is blowing around 35-45 degrees.

• C.

Explain that there's a difference between how much a vehicle will hold vs. how much it actually needs. Sell them a gauge because venting refrigerant in the parking lot doesn't get it all out. (And,of course, it's illegal!)

C. Explain that there's a difference between how much a vehicle will hold vs. how much it actually needs. Sell them a gauge because venting refrigerant in the parking lot doesn't get it all out. (And,of course, it's illegal!)
Explanation
The correct answer is to explain that there's a difference between how much a vehicle will hold vs. how much it actually needs and to sell them a gauge because venting refrigerant in the parking lot doesn't get it all out. This answer is correct because it addresses the customer's question about how many cans of refrigerant they need for their system. It explains that the amount a vehicle can hold is different from the amount it actually needs, and emphasizes the importance of using a gauge to properly measure and add refrigerant. Additionally, it highlights the illegality and inefficiency of venting refrigerant in the parking lot.

The #1 reason for compressor returns is oil starvation. this happens most often when the compressor is not properly hand rotated prior to installation. What should you always recommend to help prevent this?

• A.

1st charge with ice 32; it puts a force field around anything metal inside the system.

• B.

The specified pag oil for that particular compressor.

• C.

1st charge and the correct pag oil. One is not a substitute for other. You get the most protection with both.

C. 1st charge and the correct pag oil. One is not a substitute for other. You get the most protection with both.
Explanation
The correct answer is to recommend the first charge and the correct pag oil. This is because one is not a substitute for the other and using both provides the most protection. This helps prevent oil starvation, which is the number one reason for compressor returns. Properly hand rotating the compressor prior to installation is also important to prevent oil starvation.

A customer comes into your store and is circling around the A/C products with a bewildered look on their face. you should:

• A.

Look by and ignore them. You're off in 10 minutes

• B.

Wait for them to ask a question.

• C.

Walk up to them confidently because you've been through my class and ask them how long it took the system to warm up, and if the compressor is working. If it is, and it took more than two weeks you grab A/C Pro and Super Seal. It's the best you can do before replacing components.
