Services - Air Conditioning
Air Conditioning (A/C) in your vehicle (car, truck, SUV or
van) is simply the process of removing heat from matter. All matter above the
temperature of 459 degrees F contains energy in the form of heat. Heat always
moves from hot to cold.
The function of the air conditioning system in your vehicle
is to improve upon the efficiency of this process of moving heat. To accomplish
this, the A/C system uses three methods of removing heat from your vehicle:
Radiant, Conduction and Convection.
How does this work?
- The heat in your vehicle is
blown across the evaporator coils using convection;
- The heat is absorbed into the
cool refrigerant (Freon, R-134A, etc.) inside the coils using conduction;
- The refrigerant moves the heat
to the condenser using convection;
- This heat is absorbed into the
condenser fins using conduction;
- The heat then transfers back
into the atmosphere using radiation;
The other important components include the regulation of
humidity and understanding how air movement affects our comfort. Therefore, in
order for your air conditioning system to be most effective it must do the
following three things:
- Remove heat from the interior of the vehicle;
- Remove moisture from the interior of the vehicle;
- Provide movement of air in the interior of the vehicle.
What’s going on if your air conditioner is not
Simply stated, one of the primary components of your air
conditioning system has broken down. A/C failure usually falls into one of three
- Component Failure resulting in a lack of sufficient
refrigerant to remove heat from the car is the most common failure and occurs in
about 60% of all A/C failures. This is caused by a leak. One of our trained
technicians can verify this by either using an electric leak detector or by
injecting ultraviolet dye into the A/C system along with using an ultraviolet
- Electrical Problems represent approximately 30% of A/C
failures. This can cause the compressor and fans to stop. Electrical failures
could be caused by a failed sensor or the on-board automotive computer.
- Improper Refrigerant Charge causes approximately 10% of A/C
problems. For a variety of reasons, when this occurs, the mixture of refrigerant
to oil is out of balance.
What if you are experiencing one of these issues?
|Your air blows but
is not cool.
Could be caused by any one of these
- Low Freon caused by leak
- No power to compressor
- Compressor failure
|Your air does not
Could be caused by any one of these factors:
- A/C controller on dash failure
- Fan/blower switch failure
- Bad blower motor
The Best Way to determine what is actually wrong with your
A/C system is to have one of the experienced technicians at Alabama Auto
Repair perform a professional A/C diagnostic inspection. Following the
inspection, Alabama Auto Repair will provide you with a written
estimate that will explain what we found and advise you regarding any needed A/C
repairs or service.
