Refuelling, repair and maintenance of the air conditioner

The car's air conditioning system directly affects the comfort of the driver and passengers at any time of the year. Modern climate control not only cools the air, but also maintains the correct humidity level and helps to eliminate fogging of the windows faster. 

At Hunter's Garage, we work with all car brands and perform a full range of work: from diagnostics and refueling, to complex repairs of compressors and lines, using professional diagnostic equipment and technical regulations of manufacturers. 

Car air conditioning repair services

Car air conditioning repair is needed not only in the event of a complete system failure. Often the problem begins with a minor freon leak, extraneous noise or unstable compressor operation. The main causes of malfunctions are corrosion of the mains, mechanical wear of the bearings, damage to the seals and depressurization of the system after prolonged operation.

At Hunter’s Garage we do not limit ourselves to simply replacing parts. If the unit can be restored without loss of resource, we perform repairs, which allows us to reduce costs for the car owner. We pay special attention to such elements as the compressor clutch, dryer and air conditioner radiator. In case of damage to the condenser, we repair it or replace the air conditioner radiator with a subsequent leak test.

Compressor restoration and system sealing

We perform compressor repairs using original components or high-quality proven analogues. After completion of the work, the system undergoes pressure testing and cooling efficiency control. This guarantees stable operation of the air conditioner even during peak summer loads.

Most often, we are contacted with the problem of noise, lack of cold or incorrect operation of the compressor clutch. The compressor and its restoration require high precision. We carry out defect detection of bearings, oil seals and piston group. It is important not only to replace the worn part, but also to flush the system if chips got into the main during a compressor breakdown. We also repair aluminum tubes (argon welding) and replace radiator cores, which allows the client to significantly save money compared to a complete replacement of components.

Symptoms indicating the need for repair:

• Extraneous noise or hum when the climate control system is turned on.
• Gradual decrease in cooling efficiency (air becomes warmer).
• Heavy fogging of the glass in the cabin even when the blower is on.
• Visual traces of grease on the air conditioner tubes or radiator.
• Spontaneous shutdown of the compressor clutch due to increased pressure.

Diagnostics and maintenance of the car air conditioner

Diagnostics of the car air conditioner is the foundation of the long-term operation of the system. Many car owners ignore the problem until the air conditioner simply stops working, but at this stage the compressor may already be damaged due to dry running. Our team uses professional equipment to check operating pressures, which allows you to see the real picture of the system's condition without disassembling key components. 

Antibacterial cleaning and filter replacement

Regular maintenance of the car's air conditioner helps to avoid expensive repairs and maintain the proper operation of the climate system. We pay special attention to checking the condition of the filters, the refrigerant level and the operation of the ventilation. Timely replacement of the cabin filter and cleaning the system significantly improve the air quality in the cabin.

We also perform antibacterial cleaning of the car's air conditioner using professional products. Fungus, bacteria and moisture accumulate in the evaporator, which cause an unpleasant odor and can provoke allergies. Modern equipment allows you to effectively clean the system without disassembling the interior elements.

Stages of professional diagnostics and maintenance:

• Connecting a manometer station to check the pressures in the low and high circuits.
• Checking the operation of pressure sensors and the electromagnetic clutch.
• Pressurizing the system with nitrogen (if there is a suspicion of a hidden leak).
• Antibacterial treatment of the evaporator with professional antiseptics.
• Checking the condition of the cabin filter and recommendations for its replacement.

Recharging car air conditioners

High-quality charging of a car air conditioner does not begin with pumping in refrigerant, but with proper preparation of the system. Before charging, we perform vacuuming — remove residual air, moisture and old freon. This is necessary for stable operation of the compressor and prevention of internal corrosion.

Working with R134a and R1234yf freons

We use modern service stations and precise electronic scales in our work, which allow us to fill the system strictly according to the factory parameters of a particular car. Different types of refrigerant are used for different generations of cars, in particular R134a and R1234yf freons. Each type has its own requirements for equipment,lubricants and maintenance process.

Modern cars require different approaches to refueling. Traditional freon R134a remains the standard for most cars, but new models (after 2017 release) increasingly use environmentally friendly gas R1234yf. This type of refrigerant requires different equipment, special connectors and increased safety measures during operation. We have the technical capabilities to service both types of systems, guaranteeing gas purity and the correct dosage of specialized oils (PAG or POE) that match the type of compressor in your car.

Why is it important to follow refueling technology:

• Vacuuming: Removes moisture, which when interacting with freon forms acid that corrodes the system from the inside.
• Weight accuracy: Underfilling leads to compressor overheating, overfilling — to a critical pressure jump.
• Adding oil: Provides lubrication of the moving parts of the compressor, which is critical for its resource.
• Pressure control: Final check of cooling efficiency (Delta T) after refueling.
• Tightness: Checking the spools (nipples) for leaks after the procedure is completed.
