Auto Air Conditioning in Rockwood, ON

Car Air Conditioning Repair & Maintenance in Rockwood, ON

Air conditioning is essential in modern cars, providing a comfortable temperature and ensuring clear visibility throughout the year. Previously considered a luxury, it has become a standard feature in most new vehicles.

Air conditioning keeps the car cool and comfortable during the summer months and helps control evaporation in the winter, preventing windows from fogging up. However, like other components in your car, proper care and maintenance are necessary to ensure your air conditioning system’s longevity and optimal performance.

Regular maintenance, such as checking refrigerant levels, inspecting hoses and belts, and cleaning or replacing air filters, is crucial. Neglecting maintenance can lead to potential issues, such as reduced cooling efficiency, unpleasant odours, or even system failure.

You can enjoy a consistently comfortable driving experience regardless of the weather by prioritizing air conditioning maintenance and addressing any issues.

How Does Your Car AC System Work?

The car’s AC system compresses and circulates refrigerant, which absorbs heat from the air inside the vehicle. The compressor pressurizes the refrigerant, causing it to turn into a high-pressure gas. This gas then flows through the condenser, releasing heat and becoming a high-pressure liquid. The liquid refrigerant passes through the expansion valve, which reduces its pressure, leading to a drop in temperature.

Finally, the cold refrigerant flows through the evaporator, which absorbs heat from the air, cooling it down before recirculating it to the compressor. This cycle continues, providing cool air inside the car.

What Are the Most Valuable Parts of a Car AC System?

Compressor

• The power unit of the system that divides the low-pressure side from the higher end.
• Takes the low-pressure gas and squeezes it into the high temperature/pressure gas.
• Mounted to the front of the engine and driven by the serpentine belt.

Condenser

• Lowers the temperature of the refrigerant while maintaining high pressure.
• Upon cooling, the refrigerant changes from gas to liquid.
• Like an engine radiator, it uses forced air (fan or vehicle movement) to transfer heat.
• Installed on the front of the vehicle, behind the grill.

Dryer

• Removes water from the refrigerant using a drying agent named desiccant.
• It has some system-filtering properties.
• Mounted on the high-pressure side of the system between the condenser and metering device.

Metering Drive

• Either expansion valve or fixed orifice tube.
• Lowers refrigerant pressure, which quickly drops the refrigerant temperature.
• The refrigerant is still in liquid form after leaving the metering device.
• Mounted on the high-pressure side of the system, between the dryer and firewall.

Evaporator

• In the evaporator, the refrigerant returns to its gaseous state, creating a cooling effect.
• The air inside the car is cooled and dried as it passes through the evaporator.
• The only integral that fits inside the vehicle is behind the dashboard.

Path & Characteristics of Refrigerant

• Low-temperature, low-pressure refrigerant (gas) enters the compressor.
• High-temperature, high-pressure refrigerant (gas) from the compressor.
• The refrigerant cools to a liquid in the condenser.

Dryer

• The receiver/dryer removes water from refrigerant.
• The expansion valve lowers the pressure of the refrigerant.
• In the evaporator, the refrigerant returns to a gaseous state.
• Absorbs heat as the air flows over the evaporator; it becomes cool and dry.

Common Car AC System Failures

Common failures in a car’s AC system can include:

• Refrigerant Leaks: Refrigerant can leak from the AC system over time, resulting in reduced cooling performance or even complete failure.
• Compressor Failure: The compressor can fail due to electrical problems, mechanical failure, or lack of lubrication. A failed compressor will result in the AC system being unable to cool the air.
• Condenser Issues: The condenser can become damaged or clogged, restricting airflow and reducing the cooling capacity of the AC system.
• Evaporator Problems: The evaporator can develop leaks or get clogged, resulting in insufficient cooling or no cold air from the AC vents.
• Blower Motor Failure: The blower motor, responsible for circulating air through the AC system, can malfunction, leading to reduced airflow or no air movement.
• Electrical Malfunctions: Various electrical components, such as relays, switches, or wiring, can fail, causing the AC system to stop working properly.
• Sensor or Control Module Issues: Faulty temperature sensors or control modules can disrupt the AC system’s operation, resulting in inconsistent cooling or erratic behaviour.

Regular maintenance, such as refrigerant checks, component inspections, and timely repairs, can help prevent or address these common failures in the car’s AC system. If you experience any issues with your AC system, we suggest you book an appointment at our shop.
