SYMPTOMS

There are a few common things you might notice when your car’s air conditioner needs a recharge service or repair:

Hot Air Blowing
This is most commonly due to a refrigerant leak. A quick check you do at home is to start the car, turn on the a/c and see if the compressor comes on. If it does not, we know you have an electrical problem or a refrigerant leak. If it does, then it is likely you have a control or circulation issue. Another cause could be a control problem that is causing the heat to turn on.

No Air Blowing
A blown fuse is often the cause of this problem. Another possible, but rare reason, is a faulty dashboard fan or blower switch. If replacing the fuse does not repair the problem, you will need a certified electrician to diagnose the root cause of the problem.

Strange Smell
This problem is characterized by a musty or mildew odor when the fan is turned on. This condition can indicate that mold or mildew is growing in the evaporator box requiring a cleaning procedure to eliminate this smell.

Odd Noises
A drive belt makes the air conditioning compressor turn, and that keeps the cooling refrigerant circulating. If the belt is worn, stretched or cracked it can slip or break which can make noise or stop the compressor altogether. When this happens, circulation stops and the air conditioner quits cooling. It can also cause other serious damage to other engine systems.

Common Car A/C Terms & Definitions

AIR CONDITIONING TERMS

When discussing the automobile air conditioning system some terms and definitions commonly heard are:

Freon (R12)

Freon, also known as R12, was invented in the late 1920′s and then discontinued in the early 90′s when it was found to have a negative effect on greenhouse gases.

R134a

R134a has served as a improved replacement for Freon (R12) since the 1990s because it is environmentally friendly.  It is used to charge the air conditioning system in cars.

Compressor

The compressor is the core of your car a/c system. The compressor is a pump hooked to the engine and powered by a belt.  Refrigerant is compressed and then turned into a heated gas before being sent o the condenser.

Condenser

The condenser is where the natural heat from the air is bled off by dissipation.  The condenser absorbs the heat so that the refrigerant (r134a) can cool down to a liquid form.

Dryer

The dryer is the system filter and removes contaminants and moisture from the refrigerant.

Expansion Valve

The expansion valve is a filter system that controls how much refrigerant is sent to the evaporator.  In older vehicles, the refrigerant current slowed and measured using an expansion valve.  When the refrigerant moves through either system, it becomes vaporized and becomes larger in volume, quickly cooling.

Evaporator

The evaporator eliminates heat from the inside your vehicle. Refrigerant comes in through the bottom of the evaporator as a regular liquid. The warmer air moving through the evaporator blades makes the refrigerant boil. When the refrigerant boils, it gathers a large quantity of heat.  This heat is bled off the refrigerant to outside of the car, leaving cool air which fans blow into the passenger area.
