Car AC Diagnosis at Ace Auto Repair in West Jordan, Utah

Your car’s air conditioning system may have a number of reasons why it is not blowing cold air. By catching problems early on, you may be able to prevent small problems from becoming larger. Regular maintenance will keep your AC system operating at peak performance! When you bring your vehicle to Ace Auto Repair, we will perform a comprehensive inspection of your car air conditioning system includes:

  • Testing for proper Freon levels
  • Testing for Freon contamination
  • Checking the system for refrigerant leaks
  • Clean condenser
  • Inspect AC belts, seals, and hoses for damage
  • Examining blower

Signs Your Car AC Might Not Be Working Properly

  • No air conditioning - One of the first signs that your car has an issue with its AC system is if you can’t feel hot or cold air coming out when it should. 
  • Weird noises - Behind a non-functioning air conditioner, the next easiest warning sign to spot is weird noises. Say you turn on your AC and start hearing banging or worse? A quick fix would again call upon professionals’ expertise if something needs fixing ASAP before there's major damage.
  • Nasty smells - Third, nasty smells. Turning on your AC shouldn't be an unpleasant experience but sometimes foul odors start coming out of the vents which could mean mold growth in that portion of the air conditioning unit itself.
  • Water stains - After running your air conditioning for a while, you will see water drain out. This is normal and indicates that the unit has been doing its job well! But if there's no sign of it draining - or instead just stains inside your vehicle- then something might've gone wrong with this process. 
  • AC leaks - The fifth and final warning sign is the air conditioning leak. Low pressure in your AC unit can be a sign of an impending leak, as well as coolant draining around your vehicle - even if it doesn't seem like there's anything wrong at first! 

If you suspect one of the above signs please get your vehicle checked by us, so that we may diagnose what's going on before more serious complications arise!

Reasons Your Car AC Might Not Be Working Properly

The Refrigerant Needs to Be Recharged 

This is the most common reason why your car might not be blowing cold air. There is a refrigerant that is responsible for helping the air conditioner remove heat from the air, ensuring that it blows out cold air. While it is possible for you to recharge your car’s refrigerant on your own, this could take an extended amount of time and you might end up damaging the air conditioner in the process. It is better for you to save time and avoid a larger auto air conditioning repair by trusting a trained professional to recharge your refrigerant quickly.

Leak in the Refrigerant System

Another reason why your car’s air conditioner might not be blowing cold air is that there is a leak in the refrigerant fluid. This might be hard to detect because the fluid instantly evaporates when it comes into contact with the air. This makes it hard to spot; however, a trained professional has specialized equipment that can be used to detect leaks. Some of the signs that the AC might have a leak in its refrigerant include:

  • There is a loud click when the air conditioner turns on
  • There is oil residue present around the pipe fittings and hoses of the AC system
  • There are hissing sounds coming from the system even when the engine isn’t running
  • It seems like the air conditioner is cycling between on and off quickly

A refrigerant leak is a serious problem because refrigerant itself is actually toxic. Therefore, it should only be handled using proper equipment in the hands of a trained professional.

Fans Are Failing

If your car’s air conditioner has fans that are failing, this can lead to a lack of cold air as well. Some cars have one fan while others have two. They need to work properly to not only keep you cool but your engine as well. If you think your fans might be broken, then you need to reach out to trained professionals for help with an auto AC repair.

Damaged or Failed Condenser or Car AC Condenser Leak

If you find your car AC not cooling or putting out less cold air than usual, these may be symptoms of a bad AC condenser. Or, leaks in car AC systems can cause these symptoms. Having your car AC not working properly can become a serious problem in hot weather. So, unsurprisingly, many people face replacing car AC condensers that start leaking during the summer. Here’s the simplest explanation of: 

  1. How a car AC condenser works
  2. How to identify a leak in the AC condenser
  3. What to do if your AC condenser is leaking 

How an AC Condenser Works

Almost all modern automobile AC systems operate with a condenser. The main function of this important component is converting nonliquid refrigerant into a liquid. Here’s how the auto AC condenser works within a car’s air conditioning system:

  1. When refrigerant passes from the compressor, it enters the condenser in the form of hot vapor. 
  2. As cool air moves through the AC condenser fins, it cools the refrigerant that is passing through.
  3. This creates condensation, which is the transformation of the vapor into a liquid. 

Then, when you turn on your air conditioner, the cold liquid refrigerant is routed to cool the cabin of your car. (This is similar to the way your car’s radiator works.)

Symptoms Car AC Condenser Problems

A professional auto repair technician can identify the cause of your air conditioning problem. But, if your vehicle AC stops cooling or is only cooling very little, here’s how to check car AC condenser functionality, to identify a bad or leaking condenser in your car. Look for:

  • Reduced cooling: When a car AC is outputting significantly less cool air than usual, this is a big clue that can help you quickly identify the problem and get it corrected as quickly as possible. Diminished cooling is one of the major symptoms of AC compressor leaks or a bad compressor. A damaged condenser may constrict the flow of the AC refrigerant, causing the whole cooling system to perform less efficiently. This can significantly reduce the amount of cool air your AC system produces.
  • Visible Leaks: The clearest of all signs of a car AC condenser leak is leaking that you can actually see. Through years of use, a car AC condenser may start leaking, either due to damage or just the aging of this auto part. The refrigerant in an automotive AC system is under high pressure in the compressor and the condenser. This means, depending on the size and location of the car AC condenser leak, all the refrigerant can be lost. That can disable your vehicle’s entire air conditioning system. So, when you discover a leaking AC condenser in your car, you should have the part replaced promptly.

Car AC Condenser Replacement

All the refrigerant in a car air conditioning system must pass through the condenser for conversion to the cold liquid used to generate cooling in the cabin of your car. This means that if the condenser is leaking, the breach can be expected to negatively impact the output of cool air from the AC system. When that happens, you will need to replace your AC condenser to enjoy a comfortable level of air conditioning in the vehicle. 

So, if you are experiencing a loss of cooling due to a car ac condenser leak, have your AC system assessed by a professional technician, and have the part replaced if necessary.

Clogged Expansion Valve

In order to ensure that your AC system continues running smoothly and efficiently, it is important for you to regularly maintain the various parts within. One such part, in particular, is expansion valves which regulate how much refrigerant flows through them by opening or closing. If the expansion valve is stuck open or clogged, the AC system won’t cool properly. A clogged valve leads to the insufficient refrigerant, increasing the pressure in the system and causing the AC compressor to overheat. If the valve is stuck open, too much refrigerant is allowed to pass through the system and into the compressor. If the expansion valve fails, it can cause problems with the functionality and performance of the AC system – and if ignored, it can be expensive, with irreversible damages to other system components.

Additional Reasons Include:

  • Faulty Compressor
  • Damaged or Failed Evaporator
  • Freon Leak
  • Leaks in System Seals – Core Case Seals, Blower House Seal &/Or Evaporator Core Case Seals
  • Bad Blower Motor
  • Failed Switch
  • Vacuum Leak
  • Hose Came Loose or Damaged
  • Failed Blower Motor

How Does AC Work in a Car?

A car air conditioning system is made up of many different components that all work together to produce cold air. One important component is the compressor, which uses refrigerant to cool down the hot engine coolant (or anti-freeze), and then pumps it through an evaporator where it can release some heat. Car AC repair is necessary for any issues with your vehicle's AC system, so make sure you take care of any problems as soon as you notice them!

AC System Refrigerants

Previously, automobile air conditioning systems utilized R-12 as the refrigerant. R-12 (also known as Freon) is a highly effective CFC refrigerant that isn't flammable or poisonous to humans. During the late 1980s, researchers discovered that widespread use of R-12 was damaging the ozone layer in the atmosphere.

In the mid-1990s, manufacturers switched to R-134a. R-134a is an HFC refrigerant (hydrofluorocarbon) that does not have the ozone-depleting qualities of R-12/Freon. The newest refrigerant, R-1234yf, generates fewer greenhouse gases than the previous one.

Car AC System Parts

Automobile air conditioning systems have a few key components. Listed below are the main parts and their roles:


  • It's the system's power unit that distinguishes the low-pressure side from the high-pressure side.
  • Compresses low-pressure gas into high-temperature/high-pressure gas.
  • Mounted to the front of the engine and driven by a serpentine belt


  • It lowers the temperature of refrigerant while maintaining high pressure.
  • As the refrigerant cools, it changes from a gas to a liquid state.
  • It works similarly to an automobile engine radiator, using forced air (fan or vehicle movement) to transfer heat.
  • In front of the vehicle, behind the grill


  • Removes the water from the refrigerant by using a desiccant (drying agent).
  • Has some filtering capabilities that may be applied to a system.
  • Between the condenser and metering device, it is mounted on the high-pressure side of the system.

Metering Device

  • is either an expansion valve or fixed orifice tube
  • Reduces refrigerant pressure, which reduces the temperature of the refrigerant quickly.
  • After leaving the metering device, the refrigerant is still in a liquid state.
  • Between the dryer and firewall, it is installed on the high-pressure side of the system.


  • When the refrigerant in the evaporator reverts to a gas state, it creates a cooling effect.
  • When the cabin air enters the evaporator, it is cooled and dried.
  • The only component that is mounted inside the passenger compartment, behind the dashboard.

Path and Characteristics of Refrigerant

  • The compressor (gas) receives low-temperature/low-pressure refrigerant.
  • High-temperature/high-pressure refrigerant leaves the compressor (gas)
  • In the condenser, the refrigerant cools and changes to a liquid.
    • Still under high pressure
  • Receiver/dryer removes water from refrigerant
  • Expansion valve reduces refrigerant pressure
  • The refrigerant reverts to a gaseous condition in the evaporator.
    • Heat is absorbed; when air blows over the evaporator, it is cold and dry.

Frequently Asked Questions for Car Air Conditioner Repair and Recharge in West Jordan, Utah

Unlike some of your vehicle's other systems, there isn't a maintenance or service schedule for its AC. In short, the frequency that you'll need to service your car AC is directly related to its performance. If you notice that the system simply isn't blowing cold air like it used to, then it's time for an inspection by a professional.
Servicing an AC that has vents only in the front of the vehicle will be less expensive than one that is dual AC with vents in the backseat as well. At Ace Auto, our AC repair service package includes car AC diagnosis, leak check, valve replacement, if needed, and freon recharge. Call us with the make and model of your car for a price estimate.
Unusual noises coming from your air conditioner are often the first sign that something is wrong. If you hear a hissing noise after you turn the car off, you might be concerned but it's actually normal. It's simply your AC system equalizing the pressure by moving the freon. A loud squealing noise is another noise that is noticed. It can indicate that there is an issue with the serpentine belt. A buzzing noise that occurs when the AC is turned on signals that your AC compressor is starting to go bad. A sign that your system has been overcharged with freon, it won't cool properly and can lead to having to replace the entire compressor if it isn't addressed quickly. Clicking or knocking sounds could indicate that a component of the air conditioning has loose mounting bolts that need to be tightened properly. A rattling noise that is constant while the air conditioner is turned on could have a few different causes. The compressor clutch or the compressor itself could be failing. It could also be a sign that the serpentine belt or compressor clutch is going bad.
Finding a puddle of water under your vehicle can be troubling. It's even more concerning, though, when the water unexpectedly appears inside your car. Finding a few drips of water underneath your vehicle after you've been running the air conditioner is considered to be a normal occurrence. A puddle or an amount that increases over time, however, requires further investigation by a professional. Water that is found inside your vehicle could be a sign that your AC is leaking if you've been using it. There are a few different reasons that could be the cause. For example, the evaporator drain could be clogged with dirt or other debris or the seals that are part of your system could be failing. Both situations could allow water to make its way inside your car. Another possibility is that the evaporator core itself is leaking. This is often marked by a musky smell that comes from the vents. As experts who specialize in diagnosing issues and air conditioning repair, Ace Auto is the place to go for answers.
If your vehicle's AC compressor is failing, chances are you'll notice some signs. One of the most noticeable of these is that the air that your AC is blowing out isn't as cold as it once was. You might also hear grinding, squeaking or other loud noises when you turn on the AC. Your AC compressor might have an issue with the clutch. This could mean that the compressor is activated all the time and never turns off or it could result in the compressor not working at all. Some symptoms are most noticeable to those who are experienced at working on such systems. For example, damage and wear to the belts and/or compressor that is evident during a visual inspection could also be the reason for the compressor failing.
Not only is a damp smell that comes out of your AC unpleasant, but it can also spread allergens around the cabin of your vehicle. The AC & Heater Duct Cleaner offered by Ace Auto cleans and deodorizes the entire system, removing the bacteria, mold, stale air, and algae that sometimes collects there. In place of that unpleasant, damp smell will be a fresh, clean scent.
Servicing a vehicle's AC system not only requires expert knowledge but also specialized tools. Your AC system is a highly-pressurized environment that requires specific expertise in order to work on it safely. It is also illegal to allow the system's refrigerant to escape into the environment so it must be recovered.
There are various possible reasons why a vehicle’s air conditioning system may start producing less cool air. If your car’s A/C system is not cooling properly, you should get the system examined and have the necessary car ac repair done as soon as possible. Having a small timely auto air conditioning repair can frequently avoid much larger issues such as Black Death or other serious A/C problems. Here are some issues that can cause a vehicle air conditioning system to lose some or all of its cooling ability:
  • Freon is leaking from breech seal, hose, or failed O-ring or other component
  • Refrigerant charging hose clogged
  • Blower motor resistor not working or fan motor
  • Leaking vacuum line
  • Evaporator or condenser damaged or not working
  • Refrigerant needs to be recharged
  • Expansion tube clogged
  • Compressor clutch or compressor failed
  • Failed fuse, control, switch, relay, solenoid, or other part broken
A leak in an automobile air conditioning system that is detected early can cost less to repair. If a leak continues, it can cause moisture to enter the A/C system, which can lead to damage of major parts.
An important clue that your car air conditioning system needs attention is quickly diminishing performance when you turn on the A/C. Some potential problems that produce this symptom include:
  • Leaks in seals or other A/C components due moisture or damage
  • Blown fuse stopping power to some parts of the A/C system
  • Clogged expansion valve preventing refrigerant flow to the evaporator
  • Bad compressor clutch causing incorrect pressure in the compressor

What is “Black Death?”

This mechanical problem spreads like a disease through your car’s A/C system. Black Death starts with the breaking down of refrigerant in your air conditioner compressor. The refrigerant serves to lubricate the system, not unlike the way motor oil lubricates the engine. When the refrigerant decomposes, the loss of this lubricant leads to friction in the compressor, which leads to rapid and severe wearing.
The wearing causes sharp metal particles covered with the grime of the disintegrated refrigerant to circulate through and damage the entire air conditioning system. Soon, the A/C system quits generating cold air and ultimately may produce no airflow at all.
If your car’s air conditioner has begun generating less airflow, you should have your A/C system examined and get minor car air conditioning repairs done. This can prevent potentially serious damage to the A/C system. Sometimes, mildew or mold can accumulate in the air A/C system’s evaporator core, due to moisture residue that can form while the system is performing its process for generating cold air. When this occurs, it can be more difficult for air to reach the air vents, resulting in weak airflow. Potential causes of weak airflow include:
  • Loose blower hose (duct)
  • Open blower housing seals
  • Burned out ventilation fan
  • Open evaporator core case seals
There are not usually any dashboard indicator lights or symbols for warning car owners of A/C system trouble. However, there are some vehicles with Driver Information Centers (DICs) which may include status indicators for numerous operating processes in the automobile, including the air conditioning system. See your vehicle owner’s manual for information. Have routine air conditioning system checkups and maintenance, in order to help prevent potential performance issues and keep the system running as designed.
Locating a car A/C system leak involves examination with some specially designed tools for auto air conditioning problem detection. Many refrigerants come pre-mixed with a specially formulated dye that is visible under UV-A light. Your auto air conditioning specialist can use the black light to examine the A/C system for detecting any issues that become highlighted by it. An additional tool, called a sniffer is a device that detects the chemical ingredients of the refrigerant, for purposes of discovering problems in the A/C system.
Moisture, damage, or just aging takes a toll on the rubber hoses and/or seals as well as other parts in an automobile air conditioning system. The rubber parts can lose elasticity as they age. This can allow moisture to seep into the A/C system, or it can let freon escape. Moisture can destroy A/C systems.
When moisture becomes mixed with the A/C refrigerant, it can produce an acid that is corrosive to the parts of the air conditioning system. For example, parts that are designed to remove moisture from the car A/C system, such as the accumulator or drier, can become damaged by moisture in the system and will no longer function after a leak occurs that exposes the A/C system.
