Warm weather or cold, North Carolina drivers still need to think about their sedan’s air conditioning. Most people don’t service their air conditioning until after it fails. At Eurobahn Motorsports, we can advise you on your vehicle manufacturer’s preventive maintenance schedules for BMW service, just as we do for transmission service, oil changes and so on.
Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the sedan’s air conditioning system allow the refrigerant to escape and the system can’t cool the air as well. We see that a lot at Eurobahn Motorsports in Greensboro.
The refrigerant also contains a special oil that lubricates air conditioning components, and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all North Carolina car owners know that air conditioning repairs can be costly. At Eurobahn Motorsports BMW, we recommended that the air conditioner be run regularly, even during winter months, to keep the parts and seals lubricated.
BMW Air conditioning service at Eurobahn Motorsports starts with a visual inspection of the components for signs of damage or leaks. The compressor is driven by a belt from the engine, most often the serpentine belt, so it’s inspected for cracks or wear. The air conditioning compressor and other components are checked for proper operation. Then comes the leak test. If a leak is detected, often in a hose or connection, it’s repaired and the system is retested.
Then the old refrigerant is evacuated and the system is recharged with clean, fresh refrigerant. A final test insures that the sedan’s air conditioner is working, and you’re on your way.
How often this should be done varies from vehicle to vehicle. Your sedan owner’s manual will have the manufacturer’s recommendation and, of course, your Eurobahn service advisor can tell you. It’s typically every two years.
If you’re not getting enough cool air you know something’s wrong. Also, if you hear strange sounds when you turn the air on, there might be a problem with the compressor and you should get it checked out at Eurobahn. Replacing a bad A/C clutch in a sedan is cheaper than waiting for it to ruin the compressor.
BMW Greensboro drivers need to be aware that there’s one more thing that isn’t directly related to air conditioning service, but does impact the quality of the air in your sedan. And that’s your cabin air filter. This filter cleans dust, pollen, pollution and other impurities in the air that comes from the heater and air conditioner. The cabin air filter needs to be replaced when it’s dirty. If you don’t it’ll start to smell. Not all vehicles have one, so ask your Eurobahn service advisor to check your cabin air filter at the same time they’re doing your air conditioning service.
