This particular cabin air filter came from a Volvo class 8 truck and it hadn’t been changed for three years! It was retired in favor of a replacement. We wanted to share this photo with you to show you how cabin air filters do their job
The purpose of desiccant in a mobile air conditioning system is to absorb and hold
moisture. Moisture in a system (above an acceptable level) can lead to corrosion and
degradation of the lubricant.
If on a humid day, you turn on your car’s A/C system and a fine mist blows out of the vents, don’t be alarmed.
Some odor treatments are merely feeble attempts to cover up odor. They are doomed to fail. Almost all odor treatment products fail to provide a long-term residual effect that can reduce the reoccurrence of odor. Here is a brief description of the performance capabilities of various odor treatments by product type.
/C system odors typically result from uncontrolled growth of bacteria and other microorganisms in the evaporator part. Nasty little beasts like aspergillus, cladesporium and penicillium grow on cooling coils and other areas. How do these beasts get there?
They are naturally present in outdoor air and are drawn into the system through the evaporator during system operation.
A 1990 amendment to the Clean Air Act has forever changed the way air conditioning systems are serviced. It is believed that the release of CFC-12 to the atmosphere is responsible for depletion of the earth’s ozone layer.
Check your owner’s manual to see if your car has a cabin air filter. If the answer is yes you may want to make a note to check with your service professional to see if it should be replaced.
ATC systems contain what we’ll refer to as three major component groups. These are: The Controller – The “brains” of the system; The Sensors – Supply the controller with pertinent…
Inside your vehicle, beneath the instrument panel, there is a unit referred to by different names depending on the vehicle manufacturer, but often referred to by the generic names “the plenum assembly” or “the case/duct assembly.”
The expansion valve’s place in the system is at the evaporator inlet. Like any other valve, its job is to control flow; in this case, the amount of refrigerant entering the evaporator.
