Your vehicle's air conditioning system needs to be kept in working order


Keep your air conditioner working all year long.

Most vehicles today come standard with an air conditioning system.  Whether it is in your vehicle, home, office, or even your refrigerator, they all operate on the same principle, namely to cool and dehumidify the air. Simply put, your vehicle’s air conditioning system removes heat from the vehicle’s cabin and releases it to the outside air through a three-step process that includes pressurization, condensation, and vaporization.  

Think of when you step out of a shower or bath; your skin begins to feel cool regardless of the outside temperature as the water on your skin starts to evaporate, drawing heat away from your skin. The process of vaporization removes moisture and heat from the air in your vehicle, making cooler air available to be circulated by the blower fan.

One important point to note is the dehumidifying function of the process.  Your vehicles air conditioning system needs to be in working order even when outside temperatures do not require cooling as the system dries the air introduced into the passenger compartment, this is the reason the A/C system cycles when the defrost is selected on the vehicles climate control centre.  

The air blown onto the windshield has been dehumidified. Otherwise, moist air blown onto the cold windshield will cause frost to form on the inside, a potentially unsafe situation.

Air conditioning systems are fairly reliable when maintained as required.  The A/C system should have its refrigerant evacuated, filtered and a top-up of new lubricant on a regular basis.  

Specialized equipment and training are required to do this as system pressures can be quite high (over 300psi) on the pressurized side (known as the high side) and can be dangerous to the untrained or unqualified individual.
