A malfunctioning air conditioner is every summertime driver’s worst nightmare. We all look forward to that icy blast of air when we turn the key—and missing it can be devastating. Keep the cold air flowing by looking for these ten signs of automotive AC failure.
Inadequate Airflow
Weak airflow has several causes, with cabin air filter clogs being the most notable. Another potential cause is a refrigerant leak that reduces cooling capacity. Finally, a malfunctioning compressor may lead to weak airflow. No matter the cause, drivers should schedule BMW Repair Merriam, KS at the first sign of low airflow.
Strange Noises
If your AC makes noises on startup, it’s important to investigate them. Rattling, squealing, and grinding noises indicate significant problems with a car’s HVAC system, including belt damage, compressor failure, and loose parts. A local AC technician will discover why it’s making noise and keep minor issues from turning into major problems.
Hot Air
Sometimes, BMW HVAC systems blow nothing but hot air. Refrigerant leaks and compressor failures cause many of these problems because they limit a system’s cooling capacity. Our technicians will find out why your system is blowing hot air and get it cooling again.
Foul Odors
If there’s a musty or coming from your air vents, there’s a problem within the system. Condensation can build up in ductwork, leading to mold growth and low air quality. With help from a licensed technician, drivers will breathe easier.
Excessive Vibration
If the system shakes when it’s turned on, there may be an issue with the compressor or other parts. Most vibrations are caused by belt damage, compressor failure, or AC clutch issues. Ignoring vibrations can be risky, as they may lead to complete system failure and costly repairs.
Decreased Fuel Economy
When a BMW’s air conditioner doesn’t work as it should, it puts more strain on the engine and consumes more fuel. Although its signs are very subtle, a failing HVAC system may decrease fuel economy.
Power Cycling
Anytime an air conditioner switches on and off rapidly, it’s cause for concern. When this happens, it increases strain and wear on the system and increases the risk of failure. If your BMW’s air conditioner power cycles often, bring it in for service as soon as possible.
How Long Should Your AC Last Before It Needs Repairs?
BMWs are built to last, and their HVAC systems are no exception. Several factors determine system longevity, including the local climate and the frequency of use. Generally, air conditioners last eight to ten years before needing regular repairs, including system recharge, belt replacement, or compressor replacement. Whether your repair needs are minor or major, we can help.
