Auto Air Conditioning Repair

Major Auto air conditioning repairs could be avoided or delayed if some components of the air conditioning system are well maintained and operating at 100 % efficiency.

Car Air Conditioning condenser location

The air conditioning condenser is a heat exchanger like a radiator. It is usually located in front of the vehicle. Other automotive air conditioning designs could have the a/c condenser positioned below the radiator ,on the side of the vehicle or on the roof of the cab.

Automotive air conditioning Repair

The modern design air conditioning condenser cannot be flushed or repaired for leaks. If the condenser is internally contaminated with debris from a compressor failure, stop leak sealer or desiccant bag ruptures, the condenser must be replaced with a new efficient design condenser to ensure a longer life of the air conditioning compressor, and the best performance out of the a/c system.

Auto Air conditioning Condenser Installation

The auto air conditioning operation will be impacted by the condenser design type installed. When replacing the ac condenser, it is vital for the auto air conditioning peak performance to have the fan assembly installed according to manufacturer specifications. Condenser fan assembly ,fan clutch and fan shroud must be replaced if they are suspected of being underperforming or damaged.

The auto air conditioning longevity depends on the proper operation of the ac condenser. The A/C system must be refrigerant charged (Freon) according to specification and the refrigerant must comply at least with the current purity standards. After the condenser is replaced the system must be oil balanced to compensate for the oil loss that goes inside the old condenser coil. The type of oil used, and the exact amount of oil is critical to ensure the best auto air conditioning system performance.

Forced Air and Ram Air automotive system.

The Parallel Flow air conditioning Condenser is the most efficient automotive design currently available and it has considerably improved the automotive cabin interior comfort, but It cannot rely only on the outside ambient natural air flow and temperature to achieve the task of desuperheating, condensing and  subcooling that happens along its coil passages and fins. It is  imperative that a condenser fan assembly forces the right amount of air through the condenser and at the right speed to help with these heat exchange process between the superheated refrigerant from the vehicle cabin and the outside ambient air.

Auto Air conditioning system and Engine Overheating

Just because the engine temperature isn’t elevated, doesn’t mean that the fan is working properly. The fan operation should be double checked with the impact of the fan assembly on the ac system in mind and not only the engine cooling system operation. Just because the fan is turning, and the engine is not showing signs of overheating condition it doesn’t necessarily mean that is turning fast enough for the proper operation of the air conditioning system. Poor fan clutch performance would increase the overall head pressure of the a/c system and may develop leaks from any connection of the hvac lines or compressor main seals.

Auto Air conditioning Repair and maintenance

Depending on the conditions the vehicle is driven the auto air conditioning condenser may need periodically scheduled maintenance.

  • The condenser coil must be clean
  • Free from road debris ,leaves and dirt
  • The condenser coil cannot properly operate with missing or bent fin.
  • Aftermarket modifications of the bumper, front grille and fresh air intakes affect the a/c condenser operation.
  • Aftermarket fan clutch or condenser fan assemblies out of specification must be corrected

Is my auto ac condenser operating properly

How do I know if my auto ac condenser is operating properly ?

To know if the auto ac condenser is operating properly we need a set of air conditioning gauges and accurate thermometer to measure outside ambient temperature ,condensing saturation temperature and subcooling temperature. The readings will be compared to a pressure/temperature chart for the corresponding refrigerant used in the vehicle. The readings must be in the range specified by the manufacturer and the pressure/temperature saturation chart.

The conditions for condensing are determined by the efficiency of the condenser and the heat load put on the condenser. A standard condenser ,has a condensing temperature about 30-35 F higher than the surrounding air used to absorb heat  from the condenser. Some condensers are more efficient than others and the relation between the outside air and the condensing temperature will be lower .Condensing temperatures and pressures are also dependent on the heat load given to the condenser to reject. The higher the heat load, the higher will be the condensing temperature and the corresponding pressure. The performance of the ac condenser will change according to the outside ambient temperature.

For example, if the outside ambient temperature rises to 105 F degrees , the condenser saturation temperature would rise to about 135 F

Symptoms of a bad or failing ac condenser

  • Higher relationship between condensing temperature and outside ambient temperature.
  • Higher A/C system head pressure
  • Lower A/C compressor capacity.
  • Condenser fan assembly operating on high continuously

 

How to properly install an ac condenser

 

When installing a replacement condenser,  measure the amount of oil found in the component that was removed, and then add that same amount of oil, back into the condenser prior to recharging. If oil has leaked out of the system, use the manufacturer’s recommended amounts.

  • Torque all fasteners to manufacturer’s specifications.
  • Replace o-rings
  • Evacuate and recharge the system
  • Check for leaks
  • Check A/C system performance.

Weak air flow from ac vents in car

Weak air flow from a/c vents in car

Weak air flow from a/c vents in a car could be caused by:

  • Underperforming A/C Blower motor
  • Restricted in cabin air filter
  • Restricted a/c evaporator core
  • Auto a/c system low on refrigerant charge(Freon)
  • Faulty Expansion device
  • Incorrect refrigerant charge after service
  • A/C system contaminated with moisture.
  • Auto A/C compressor operating constantly
  • ECU cycling control bypassed
  • A/C cycling control switches bypassed
  • Evaporator temperature sensor malfunction
  • In cabin temperature sensor malfunction.
  • A/C ducts restricted with debris
  • A/C ducts flaps partially closed

How much air should be coming out of vents ?

The amount of air that should come out from the vents will depend on the settings the driver has selected. In Automatic Temperature Control systems (ATC) the driver can choose a given temperature  and have this temperature setting maintained by the a/c and heater control system.

This Fully automatic systems usually control most of the specific functions of mode operation, temperature control, blower speeds and heater temperature control. The system will automatically maintain the desired temperature and quantity of air for each mode  and will route the airflow according to the need.

Why is my vent blowing weak air out.

One of these could be the reason why the vent is not blowing out enough air:

  • Fuses, fusible links, and wiring
  • Refrigerant charge and compressor operation
  • Coolant level
  • Heater core
  • Evaporator core
  • Blower motor control module
  • ECU
  • ECM
  • BCM
  • PCM
  • Ambient temperature sensor
  • Sun Load Sensor
  • Coolant temperature sensor.

The proper function of the ATC depends upon the electrical inputs of several sensors. The programming that enables the ECM  to provide control of the system naturally tells the engine computer how to interpret these signals. The ambient temperature sensor is located just behind the grille outside the vehicle. Its job is to sense the outside air temperature and to adjust the ATC accordingly. In cold outside temperature the a/c compressor may be blocked to prevent ac compressor damage due to lack of proper internal oil lubrication.

The sun load sensor is mounted on top of the instrument panel. It senses the intensity of sunlight and adjusts the ATC to meet the demand.

Coolant temperature sensor. Its signal may come to the programmer directly, or be communicated to the programmer by the electronic control module (ECM).

How to unclog weak air flow from ac vents in a car

Poor air flow from vents in a vehicle could be related to any of the issues mentioned above. With the right tools and training the vehicle could be operating up to specifications in no time.

How do you flush an auto AC system?

Most automotive manufacturers recommend closed loop flushing with air conditioning refrigerant as a flushing agent. A benefit of this type of flushing is there is no danger of flush contamination , since the flush agent being used is the correct refrigerant for the A/C system.

Avoid this type of auto ac system flushing

Over the years many different liquids have been used as non-approved flushes for a/c systems. The more common are:

  • Alcohol
  • Brake cleaner
  • Carburetor cleaner
  • Mineral Spirits
  • Penetrating oil
  • R-11, R-12, R-113
  • Gasoline

The use of unapproved chemical flushes can result in damage to rubber components in sealing washers, auto ac compressor shaft seals, O-rings and hoses.

At no time should these products be used as a flush agent. If a compressor failure is caused by non-approved flushing agent being left behind in the a/c system, it can void the compressor warranty.

How often should you flush your auto AC system?

When an auto A/C system has become contaminated with air, moisture, flushing agents, the automotive ac compressor oil is contaminated with an incorrect type of oil or from debris from an internal auto ac component failure , or the system has been overcharged with oil, dye,  it must be flushed.

What happens if you don’t flush the AC system in your auto?

The debris created from internal auto ac compressor failure can accumulate and become trapped in the various a/c system components , and restrict the flow of refrigerant and oil. When used in a quantity beyond what the dye manufacturer recommends, dye can modify the viscosity of the ac compressor oil and becomes contaminant. Air as a contaminant may cause decreased auto ac cooling performance, create car ac compressor noise, or increase system pressures. Contaminated auto a/c systems may cause hvac compressor failure, air conditioning hose and line damage due to excessive heat and high pressure and overall automotive a/c system performance decrease.

  • Brake cleaner
  • Carburetor cleaner
  • Mineral spirits
  • Penetrating oil
  • R-11, R-22, R-113
  • Gasoline

Automotive AC system contamination with liquid flush agents

The use of unapproved chemical flushes can result in damage to rubber components in sealing washers , compressor shaft seals , O-rings and hoses.

Automotive A/C compressor internal damage

Unapproved chemical flushes when mixed with the auto ac compressor oil , it will alter the viscosity of the oil as well. Any material left behind in the a/c system after flushing will dilute the lubricant and cause performance issues , increased compressor noise and premature compressor failure. If compressor failure is caused by non-approved flushing agent being left behind in the a/c system it can void the compressor warranty.

Why do I have to flush my auto A/C System?

In the early years of auto A/C repair, system contamination was associated with debris from an internal auto ac compressor failure. Over the years, the types of auto air conditioning contamination  have expanded. This would include items such as:

  • Metal and Teflon
  • Sealant
  • Moisture
  • Compressor lubricant
  • Leak detection dye
  • Air
  • Refrigerant
  • Solvent-based flush agent
  • Lubricant additives
  • Non-approved flushes

Auto A/C system contamination

Metal and Teflon :Metal debris can be created from any metal component inside the compressor self-destructing , and Teflon can come from the Teflon seals on the a/c compressor pistons.

Sealant: Refrigerant sealers have been used in automotive applications for years. Sealants can act as a stop-leak for auto ac refrigerant lines, or they can act as a conditioner for automotive ac O-rings. When sealant is added to an automotive air conditioning refrigerant system , it remains in solution and when the leak is found , the sealant reacts to moisture in the atmosphere, filling the hole. If air or moisture is present in the auto ac system, the sealant will gel. Sealant can plug an orifice tube, TXV, and tubes in an auto ac condenser or evaporator.

SEALANT USE HAS NOT BEEN APPROVED BY ANY VEHICLE MANUFACTURER OR A/C COMPONENT MANUFACTURER. WHEN AN AUTOMOTIVE AC COMPONENT FAILS UNDER WARRANTY, THE WARRANTY COULD BE VOID IF IT IS DETERMINED THE SEALANT CAUSED THE PART TO FAIL.

Moisture: Moisture can enter the auto a/c refrigerant system from three sources- the atmosphere ,contaminated PAG oil or contaminated Refrigerant.

Compressor Lubricant : Automotive a/c Compressor lubricant becomes a contaminant when an incorrect type or a non-approved lubricant is used. Mixing two or more different types of car a/c compressor oils can also create a contamination situation.

Leak detection Dye: When used in a quantity beyond what the dye manufacturer recommends, dye can modify the viscosity of the auto ac compressor oil and becomes a contaminant.

Air: Air can enter the automotive ac refrigerant system from a leak or when an insufficient vacuum is pulled during the refrigerant recharge process. Air can also be introduced into the system through the use of recycled refrigerant that contains air in it.

Refrigerant :Auto A/C Blend refrigerants are not approved by vehicle manufacturers as a replacement for R-12 or R-134a.

Lubricant additives : Unless recommended by the vehicle OEM , careful consideration should be given to the use of any of these products . While some additives may not harm an A/C system, others may have a negative impact on them.
