[ "ALL YOU NEED TO KNOW ABOUT CAR AC SERVICEIt is very uncomfortable to travel without AC in summer. The car temperature can go up to 60C, so you must check your Air Conditioning Northampton. Improper maintenance can cause numerous issues like odour, low cooling, failed compressor, etcComponents Of Car ACCompressorThe use of the compressor is to compress the refrigerant. It plays the role of a pump, pressurising and passing the refrigerant to the evaporator. It is powered by the drive-belt.RefrigerantIt is a fluid contained within the AC system coils, which is responsible for cooling. Tetrafluroethane or R134-a has become the most common car AC refrigerant, replacing Freon in 1993CondenserA condenser which is a mesh of coils is arranged in a zig-zag pattern to extract heat from the compressed gas with ease. It converts the gas into a liquid, thus acting as a heat exchanger.EvaporatorThe evaporator changes the state of the refrigerant from liquid to gas. It has the exact opposite role of the condenser. Located inside the car, it disperses the heat and lowers the temperature furtherExpansion ValveThe expansion valve and the evaporator work together and regulate the refrigerant pressure through the AC systemDryer/AccumulatorThe desiccant in the accumulator absorbs the moisture that gets into the cabin and the AC system.Car AC Service  WorkingWhen taken for AC servicing, the technician first checks the cabins temperature  the ideal range is 5C-10C. Then they will check to see how much refrigerant is left in the system. The ACs cooling ability depends on the refrigerant level; if its too low, then it adversely affects cooling. The mechanic uses a pressure gauge and a precision AC gas recharging machine to expel it and fill it up to the recommended levelThey also inspect the AC line and hoses to see if there is any leak or crack. They might use a UV dye for better detection. The compressor is the most crucial and expensive component of the car AC. It powers everything, and any malfunction will bring down the whole system. So, get it checked and serviced every year and replace the compressor oil tooThe technician examines the condenser for a clogged line or bent or damaged fins. If it is clogged, the condenser is washed in water with low pressure. They also check the dryer and see if there is any moisture build-up in the evaporator. The cabin filter is also cleaned. After every 15000km, it needs replacing.5 Common Car AC ProblemsCar AC not cooling enoughA failed compressor or low level of refrigerant can cause this. It will cost you quite a bit to fix this problem. Or, it can arise due to a clogged condenser (this leads to a decrease in the coils surface area, leading to less cooling)Bad odour from the ACIt is a problem faced by almost all car owners. When the AC filter has mould or mildew, it will give a faint smell, while moisture will give off a strong foul odour. You have to clean or replace the filter when this happens.If you get the smell of rotten eggs when the AC system is on, there might be a dead animal in the system. In this case, get a professional to help you in this matter.Loud whirring noiseIf the compressor is shot, it will emit a loud high-pitched whirring noise. This noise is generated from the engine bay. If you hear the sound from the cabins inside, you probably need to repair or replace the blower fan assembly.Water Seeping Inside The CabinWater forms when the refrigerant condenses when flowing through the evaporator. The drain tube lets the water flow outside; if it is blocked, water will accumulate in the cabinEngine OverheatingThe engine powers the compressor too. If the clutch on the compressor seizes, it puts an unnecessary load on it. It overheats the engineHow To Maintain Your Car AC At Home?Wipe The VentsThe dust on the AC vent accumulates eventually and clogs up the cooling coil. So, the cooling ability gets affected. To avoid this, clean the vent with a brush or a sponge.Clean The Cabin FilterThe cabin or HVAC filter behind the glove box gets clogged from dust and debris. Plus, the mildew and mould formed can give off a foul odour when you switch on the AC. Clean the AC filter and the fins with a brush; use a deodoriser before installationClean The CondenserSituated behind the cars front bumper, the condenser is made of aluminium fins and lines for fresh air intake. The fan aids the cooling of the refrigerant. To get optimum cooling, wash the condenser with mild pressure water. This will expel all the stuck leaves, debris, and dustThe servicing of the AC system is crucial; you cannot avoid it. So, you should have your car AC checked at regular intervals along with getting a full AC service once every year." ]
