How To Know If Your Car’s A/C Evaporator Needs Maintenance


Particularly in the hottest months of summer, one of the most grueling and frustrating things to deal with as an automobile owner is a broken air conditioning system. To keep the interior of your car cool, a multitude of components work together. Your vehicle’s A/C evaporator is one of the most crucial components. While, without warning, problems can arise, it is still one of the heartier components involved.

With proper A/C evaporator maintenance, you can keep your system running better and longer. Let’s take a look at some regularly scheduled maintenance suggestions and how to know if A/C evaporator maintenance is needed.

Automotive A/C Cleaning Suggestions

A cleaner automotive air conditioning system works better and lasts longer. Today’s automotive technicians suggest sticking to a preventative maintenance program for cleaning the A/C system in your vehicle. Here are a few suggestions:

  • At least every couple of months, use high-pressure water to spray the A/C condenser.
  • At least once every year, change your cabin filter (or more depending on excessive automobile usage, the cleanliness of your environment, etc.).
  • At least twice every year (once if you don’t use your vehicle very often), the A/C evaporator in your vehicle should be cleaned to reduce future problems.

Faulty or Failing A/C Evaporator – Signs and Symptoms

It’s relatively easy to diagnose any number of automotive air conditioning system problems. It might take a longer time for the interior of your vehicle to cool down, for example.

It’s also simple to diagnose lackluster performance from your vehicle’s A/C evaporator. That said, here are four things that you could be experiencing if there is a problem with the A/C evaporator:

  • Temperature Variations: You may notice that the temperature in your vehicle is fluctuating, even though you’ve done nothing to adjust it. Though it isn’t remaining constant, the air can still be cool, however.
  • Non-Activation of the Compressor: Refrigerant runs through your system – and cool air through the vehicle – courtesy of being circulated by the compressor. To operate, a predetermined set pressure is relied upon. Reduced pressure can be caused by a leak, and the system won’t blow as efficiently. There could be an A/C compressor problem if weak airflow is experienced.
  • Strange Odor from the Vents: If, blowing out of your vents, you detect an odd odor, a small refrigerant leak might be coming from the seals, the core, or the coils. Your cabin may be filled with an odor that some describe as a “sweet smell.” If you turn the air higher, the smell will get stronger.
  • Temperature and Airflow Issues: The core or A/C evaporator may be leaking if you find that no air is blowing at all or what air is blowing is weak. The effectiveness of your entire A/C system is impacted by this problem. Generally speaking, greater impact will be experienced the larger the leak.
