Air Conditioning System
There are a variety of different air conditioning systems for cars, trucks and SUVs, but all work basically in the same manner. Warm air passes over a refrigerant, the heat
is transferred to a refrigerant, which then removes the warmer air from your vehicle cabin. There are a number of reasons why your air conditioning system may not function
properly. Corrections range from a relatively simple recharge to service of the compressor, evaporator, condenser and electrical controls.
Maintenance and Care:
Your vehicle's system should be checked annually by a trained technician. Symptoms of a low refrigerant charge include poor cooling and the compressor for the air
conditioner frequently engaging and disengaging, i.e., the air conditioning is constantly stopping and starting. Using an air conditioner low on refrigerant potentially
can cause damage to the system. Please refer to your owner’s manual for factory recommended maintenance intervals for your specific vehicle.
Also keep in mind that the air conditioning system also operates when the climate control system is set to defrost the windows. If you have any problems with defrosting
windows, have your vehicle checked out as soon as possible by a trained technician as a safety precaution. Bring your vehicle to the experts at AAMCO.
Heater Core
The heater core is the source of heat for the interior of your car, truck or SUV. It is technically part of the Cooling System in your vehicle.
Maintenance and Care:
Proper maintenance of your cooling system will help keep the heater in good condition. Depending on the type of coolant used in your vehicle, coolant typically should be
changed about every two years or 24,000 miles. Please refer to your owner's manual for factory recommended maintenance intervals for your specific vehicle. Typical signs of
a faulty heater core are poor output from the heater, coolant on your vehicle's interior floor, or a strange smell while the heat is on. Problems with a heater core generally
get worse with time, so if you notice any of these symptoms, have the system checked by the expert technicians at AAMCO.
Cabin Air Filter
Approximately half of late model vehicles now have a cabin air filter to clean incoming air for the car’s heating/ventilation/air conditioning system. This filter is
designed to trap dust, pollen, bacteria, and exhaust gases.
Maintenance and Care:
Please refer to your owner’s manual for factory recommended maintenance intervals for your specific vehicle. It should be noted however, that cabin air filter replacement
is not always noted in the owner’s manual, so a rule of thumb is replacement about every 15,000 miles. Bring your vehicle to the experts at AAMCO.
