If your car’s -air conditioning system isn’t working](, it can be hard to find out why since so many of its problems can share symptoms. Luckily, a trusted mechanic can help you inspect your car’s air conditioning system to get to the bottom of it.
How much it costs to have your car’s air conditioning system inspected can vary, but it commonly falls somewhere between $100 and $300.
It’s a real bummer when your air conditioning stops working in hot weather. It’s also hard to figure out what the culprit is on your own. That’s why car insurance super app Jerry has put together this rundown on car AC inspections.
The exact cost varies between different Mercedes-Benz models. For example, newer vehicle models are usually made with more expensive materials, so recent or high-end models will cost more, especially if your service requires a part replacement. Use the table below to estimate the cost for your own vehicle.

How does a car’s AC system work?

When different parts of your car’s air conditioning system stop working, many of them will exhibit the same symptoms. To get a better sense of what might be wrong with yours, it helps to know generally how the system works.
Your car’s air conditioning system has a low-pressure side and a high-pressure side. The AC system’s compressor controls the pressure, and the compressor clutch turns it on and off.
On the low-pressure side, the system’s refrigerant is in a gas state. When it passes through the condenser to the high-pressure side, the refrigerant becomes a hot liquid.
From there, it passes into the receiver/dryer or accumulator (your car either has one or the other), which filters excess moisture and debris from the refrigerant. Then the coolant continues on through the expansion valve or orifice tube (again, your car has one or the other), where its temperature cools and returns to its gas state on the low-pressure side. The cycle continues.
While this refrigerant continues cycling through the AC system, the evaporator is where the air actually gets cooled, and then the blower motor sends that luxuriously cool air out to you through your car’s cabin vents.
If your AC system isn’t working properly, a mechanic can inspect it for you to get to the root of the problem.

How to inspect a car’s AC system

Here are some of the problems a mechanic will look for when inspecting your AC system:
  • Too much or too little refrigerant
  • Leaks
  • Poor pressure regulation
  • Electrical problems in the AC system
  • Electrical problems related to the AC controls in the cabin
  • Mechanical problems with any AC components

When do I need to have my car’s AC system inspected?

Since your car’s air conditioning system is a sealed system, inspection is only recommended when you’re experiencing a problem with it. Many problems with different components of the AC system can share symptoms, so an inspection from a trusted mechanic can help you narrow down what the problem really is.
Common air conditioning problems include:
  • You hear strange sounds, like clicks, while your AC is on
  • You notice inconsistent temperatures in your car while driving
  • The AC system blows only hot air or kind-of cold, but not chilled air
  • You notice a mold or mildew odor when your AC runs
  • You notice a leak that could be coming from your AC system
It’s true that a working air conditioning system isn’t necessary for your car to run properly, so getting it serviced isn’t necessarily an urgent issue if you can stand the heat. However, depending on the problem, foregoing service could lead to further damage to other parts, which could cost you more money in the future, so it’s still better to get it checked out sooner than later.
