Auto Air Conditioning System Overview | ACDelco


Hi. Thanks for tuning in. I’m Peter Robert
from ACDelco and we’re here today discussing
the cold-hard facts about air conditioning
and how to ensure your vehicle keeps its cool
inside when it’s hot outside.
A vehicle’s AC system works just like the
refrigerator in your house. It removes heat
and humidity from the air by forcing refrigerant through a condenser that operates much like
a radiator to dissipate heat. The refrigerant
then flows through an evaporator, where it
absorbs heat from inside the vehicle and the cycle repeats itself.
While the basic operation of air conditioning is simple enough, it involves relatively complex
mechanical components that keep the pressurized refrigerant sealed and circulating within
a closed-loop system. A break in the system that releases pressure, allows the refrigerant
to escape. The failure of any of the other
components in the system can make for an uncomfortable
ride when it’s hot outside.
You might have a problem if:
• The air blowing out of the vents is cool,
but not as cold as it used to be
• The AC performance is spotty or intermittent – it may blow cold air briefly, but cut
out for a while before blowing cold air again • The vehicle’s floor is inexplicably
wet (there may be a plugged drainage hole)
• There’s a musty odor when the AC is
on – smells like a gym locker.
If any of these symptoms describes your vehicle,
you should have it inspected – if it’s
a GM vehicle, ACDelco offers a complete range
of GM original equipment components to get the system blowing cold air again – everything
from compressors and evaporators to the smallest valves and o-rings – ACDelco is GM original
equipment!
Because of regulations regarding the release of refrigerant from a vehicle, air conditioning
repair isn’t typically a do-it-yourself
project, but ACDelco professional service
center program participant are equipped to
inspect and repair your GM vehicle’s AC
system. Please visit acdelco.com and click
on “find a service center” to locate an
ACDelco service center near you.
One more thing, that little puddle of water
you see beneath your vehicle is a normal byproduct
of the air conditioning system. It’s the
water accumulated from the evaporator, which
exits the system through a drain in the bottom of the vehicle.
Thanks again for watching. We’ll see you
next time!
