  6. Technician is going to check your engine air filter, cabin air filter and all of your fluids
  7. The technician is also going to check safety related items as well (ie. Brakes, belts, radiator hoses)
  8. The Service advisor will then make a quote for you and then come up with the best options.

Air Conditioning System

The auto air conditioning system is a complex system that helps regulate the temperature and humidity levels inside your vehicle. It consists of several components that work together to cool the air and circulate it throughout the cabin.


The main components of the auto air conditioning system are the compressor, condenser, evaporator, and expansion valve. The compressor is responsible for compressing and circulating the refrigerant, which is the substance that cools the air. The condenser helps dissipate the heat generated by the compressor and converts the refrigerant from a gas to a liquid. The evaporator is located inside the vehicle and helps cool and dehumidify the air. Finally, the expansion valve regulates the flow of refrigerant and controls the temperature of the air.


In addition to these main components, the auto air conditioning system also includes other parts such as hoses, belts, and sensors. These components work together to ensure that the system is functioning properly and that the air inside your vehicle is comfortable and safe to breathe.


If you're experiencing problems with your auto air conditioning system, it's important to have it inspected and repaired by a professional. Common issues include leaks, worn-out components, and low refrigerant levels. A qualified technician can diagnose the problem and provide the necessary repairs to ensure that your auto air conditioning system is functioning properly.


By understanding the components and function of your auto air conditioning system, you can make informed decisions about maintenance and repairs. This knowledge can also help you identify potential issues early on and avoid costly repairs down the line.

1234yf Refrigerant

Repairs and recharges

1234YF Refrigerant is the new a/c refrigerant. Many automobile manufacturers started using this refrigerant as early as 2013. Az Auto Air has been servicing the 1234YF refrigerant since 2015. The 1234YF refrigerant is replacing the R134A refrigerant because it has a lower greenhouse effect. It is very important to have a professional repair facility handle your vehicles refrigerants system due to the fact that the 1234YF refrigerant is flammable under certain circumstances.

What to Expect when you bring in your car for service


  1. Bring your vehicle in anytime Monday through Friday till 3:30pm. No Appointment Necessary.
  2. We charge $150.00 for the a/c inspection. We will give you a written estimate for repairs. When you decide to have the repairs done with us, We will apply the $150.00 towards the repairs.
  3. We are going to preform an a/c inspection that includes checking all of the components.(ie Compressor, Condenser, Cooling fans, Mode, temperature and recirculation door, refrigerant levels.)
  4. We will also check all safety related items to ensure the vehicle is safe. ( ie Brakes, fluids, tires, belts, hoses.)
  5. If all it needs is an evacuate and recharge of the system we will also apply the $100 towards that as well.
  6. An evacuate and recharge of the 1234YF for a standard system is $350.00, If you have a dual unit system the price is $450.00.

Why the new refrigerant?

R-134a was originally the replacement for R-12 which was phased out when it was found to be harmful to the ozone layer. Years later, R-134a was found to contribute to global warming, and now it too is being phased out . Enter R-1234yf. R-134a and R-1234yf do have many similar properties. That’s because R-134a is a hydrofluorocarbon (HFC) while R-1234yf is a hydrofluoro-olefin (HFO) refrigerant. Both are composed of hydrogen, fluorine and carbon atoms. However, there are notable differences between the two refrigerants as well. While R-134a has a Global Warming Potential of 1300, R-1234yf’s GWP is less than 1.

Another difference is that R-1234yf is classified as mildly flammable, but put into context, it is interesting to note that it still has the lowest flammability of any engine component-related fluid.

Why is 1234YF so Expensive compared to R134a

The refrigeration cycles of the two refrigerants are similar because the pressure /temperature relationship of yf and R-134a are very similar. Both require the use of an SAE J2842 evaporator. The procedures for recovery and recycling, however, is a bit more complicated with yf due to the sophistication of the equipment. Vehicles with R-1234yf have different service fittings than R-134a vehicles to prevent any potential cross-contamination of the two refrigerants. That means new equipment is required to service yf vehicles. That equipment must also be approved by, and registered with, regional EPA offices. SAE standard J2843, “R-1234yf (HFO-1234yf) Recovery/Recycling/Recharging Equipment for Flammable Refrigerants for Mobile Air-Conditioning Systems,” establishes minimum equipment requirements for the recovery/recycle/recharge of R-1234yf refrigerant. In addition, technicians need to be Section 609 certificated to buy and work with 1234YF.

1234yf Warnings

  • 1234YF is a FLAMMABLE refrigerant, The flash point is high and not very likely that the refrigerant will catch fire, but there is a chance
  • 1234YF is very expensive to not get right. If there is

Engine Diagnosis and Repair

When your check engine light goes on, it’s your vehicle telling you that something is not right with it and that you should get it looked at. If the check engine light is flashing and you feel the vehicle running poorly, the vehicle is telling you to pull over and shut it down because something is not only wrong, it will cause very expensive damage to your ride if you don’t. Prevent further damage by having the vehicle towed to our shop.

AZ Auto Air Inc knows that the check engine light is one of the most misunderstood warning lamps on all vehicles since about 1996! Worse yet, you may find that some businesses in Tempe will plug into your vehicle, see what codes it is displaying and sell you parts that may not fix your vehicle based on those codes adding to the confusion about the check engine light.



As mentioned before, the check engine light is an indicator that lets you know that something is not quite right. When the tech gets a code, that code just tells the tech what sensor or system is not working correctly. So, if a code for an oxygen sensor is generated, it is telling the tech that the sensor is not operating properly, or the sensor is sending a signal that that is out of specification. It is not necessarily telling you that the sensor has actually failed. At this point a AZ Auto Air Inc technician will look up and perform a number of tests and readings to eliminate other possible causes for the code. When the testing is completed properly, the tech will have identified the actual failure which may not be the sensor at all.



In this case, if the cause is not the sensor, and the oxygen sensor is replaced, after a few miles of driving the check engine light will go on again and the same code will appear because the actual issue has not been fixed. This is why replacing parts just because the code points to them usually does not fix the issue.



AZ Auto Air Inc is one of the top shops in Tempe because our technicians will read the vehicle codes and use them to look for TSBs or other issues that your vehicle may have commonly. Next, our technician will perform a series of “pinpoint tests” as directed by the manufacturer of your ride. These tests may be electrical, or engine mechanical based on the pinpoint tests that are given. Once the cause of the check engine light is determined, we will contact you with an estimate of what it will take to repair your vehicle.



Upon authorization from you, we will repair or replace the part in question and rerun our code testing procedure after a road test to confirm that the diagnosis was correct, and that the replacement of the part fixed the issue. Note, occasionally there maybe more diagnosis required after the replacement of the initial part due to another failure in the system that the first may have overshadowed.

Digital Courtesy Inspections

Technology has increased the number of miles and time that can pass between visits to shops like AZ Auto Air Inc for service. Yet tires, brakes and other vehicle parts will still suffer from wear and tear as your ride is driven around Tempe. This makes performing a comprehensive vehicle inspection during each visit mandatory to maintain the safety and smooth operation of your vehicle.

Technology also provides digital inspections that give drivers like you a window into why a shop is recommending a repair or service on your vehicle. In the past, shops used paper inspection sheets that consisted of check marks on color swatches and illegible writing that supposedly told you the condition of the different systems on your vehicle. Making any sense of what was listed on these sheets was many times near impossible. You had to depend on the word of the advisor to understand what the numbers meant when it came to tires and brakes.



Digital vehicle inspections, sometimes referred to as DVIs, change this. When one of AZ Auto Air Inc techs performs this crucial inspection on your car or truck, he or she will use a digital tablet to make notes of findings and measurements. Even better, the technician will take multiple pictures, and even video, to give you the same point of view that they have. You will see what they see so that you can better understand the importance of what is being discussed. The tech even has the ability to draw on the pictures so that you can see exactly what they want to share with you.



AZ Auto Air Inc uses digital inspections from BOLT ON TECHNOLOGY so that you can make informed decisions on the repairs and services needed for your vehicle. Currently we are one of the few shops in Tempe that offers these inspections. Using these inspections, AZ Auto Air Inc wants to be sure that you fully understand what the condition of your car or truck is. Better yet, you can keep copies of these inspections for reference and comparison to future inspections. You can build a history of the repairs and maintenance you have performed on your vehicle building more value in your car or truck when it comes time to sell it.



Once the inspection is completed by the technician. Your service advisor will edit it and put together estimates on any work that they are recommending. The advisor will then text the inspection right to your smart phone where you can, with a couple of taps, see pictures, video and clear descriptions of what was found and what needs to be done. (If you wish, AZ Auto Air Inc can either email or print the inspection out for you if you wish.) You can be on the phone with the advisor while looking over your inspection and discuss the necessary items to take care of while having a complete idea of why.

Filters

To help your ride last as long as possible and to give you the best miles per gallon, AZ Auto Air Inc will check and inspect all the major fluids and filters on your vehicle during our comprehensive digital inspection. Free flowing filters will keep your driving smooth and problem free.

Engine Air Filter: Your engine needs lots of clean air to make it run. Of course, the engine draws this air from the atmosphere all around us. As a resident of Tempe, you know that there are different types of materials that float in the air such as pollen and dust. The engine air filter needs to remove these debris from the air before it gets into the engine where they will cause accelerated wear to occur, shortening the engine’s life.

Over time the engine air filter will become clogged with these debris resulting in a reduced air flow into the engine. If allowed to go long enough, this reduction in air flow will cut power and fuel economy for your vehicle. At AZ Auto Air Inc we will inspect and replace the filter when it is needed in addition to cleaning out any other materials that we may find in the air filter housing.

Cabin Air Filter: Many vehicles today are equipped with a cabin air filter that helps remove pollen and other debris from the air that you AC and heater system bring into your car. Being that these air filters remove pollen from the air you are breathing, you are less likely to be distracted by allergies when you drive making you a safer driver.

Cabin air filters are sometimes hard to get at so other shops may not check them. We at AZ Auto Air Inc want you to be comfortable and safe so we will check it during our inspections and let you know if it is time to replace it. If not changed when needed, these filters can limit the function of your AC, heat and defrosting of your vehicle resulting in discomfort or unsafe driving.

Fuel Filter: Though many gas stations do their best to be sure the fuel you buy is as clean as can be, it is possible that some debris can get into the fuel. These debris can affect how your fuel injectors function causing loss of power, rough idle, and other issues since the injectors have very small ports that can clog easily.

The fuel filter is generally located under your vehicle, so during our digital inspection we will be sure to check it and recommend the replace of the filter when it is due. Because the fuel system can be under pressure, we at AZ Auto Air Inc do not recommend drivers to change the filters themselves. AZ Auto Air Inc will depressurize the fuel system and use the proper tools to remove and replace the fuel filter when needed.

Hybrid/Electric Car Battery Filter: The drive battery in a hybrid or electric vehicle is one of the most expensive components of these vehicles. Heat is one of the worst enemies of these batteries so many hybrid and electric cars have a blower system and/or even an AC system built in to help keep the battery from getting too hot. An air filter is used to protect these systems from dirt and dust build up that will reduce the efficiency of these cooling components. AZ Auto Air Inc in Tempe will inspect and recommend these filters when they are needed helping keep you drive battery cool.

Fluids

Your vehicle uses several different fluids to make it do what it does. Engine oil goes through the most use and abuse, so this is why it and the oil filter need to be changed more regularly than other vehicle fluids. So, let AZ Auto Air Inc tell you about the other fluids we check and service for you during each digital inspection we perform on your vehicle.

An automobile has several different fluids that are critical for the proper functioning and maintenance of the vehicle. These fluids perform various functions, and their importance cannot be overstated. Some of the most important fluids in an automobile are:

  1. Engine oil: Engine oil is perhaps the most important fluid in an automobile as it lubricates the engine components and prevents them from wearing out. The engine oil also helps to cool the engine by carrying heat away from it.
  2. Transmission fluid: Transmission fluid is important because it lubricates the transmission components and helps to transfer power from the engine to the wheels. It also helps to cool the transmission.
  3. Brake fluid: Brake fluid is essential for the functioning of the braking system. It transmits the force from the brake pedal to the brake components, enabling the vehicle to stop or slow down. It is important to ensure that brake fluid is at the correct level and in good condition to ensure that the brakes function properly.
  4. Coolant/antifreeze: Coolant/antifreeze helps to regulate the engine temperature by carrying heat away from the engine and dispersing it through the radiator. It also prevents the engine from freezing in cold temperatures.
  5. Power steering fluid: Power steering fluid is important because it assists with the steering mechanism, making it easier for the driver to turn the steering wheel.
  6. Windshield washer fluid: Windshield washer fluid is used to clean the windshield of dirt and grime, ensuring that the driver has a clear view of the road.

In conclusion, these fluids are important because they help to ensure that the vehicle operates smoothly and efficiently. Regular maintenance of these fluids, such as checking and changing them at recommended intervals, is critical to prevent damage to the vehicle and ensure safety while driving.
