When the weather heats up, a working air conditioning system is essential for comfort on the road. But like any part of your vehicle, the AC system can develop problems over time. If your car’s AC isn’t performing the way it used to, it’s best to get it inspected. At HESCO Automotive & Performance Center, we provide expert auto AC repair in the greater Birmingham, AL area. Here are four common signs of car AC trouble. Weak or Warm Airflow One of the clearest signs of AC trouble is when the air coming from your vents is weak or not cold enough. If you’re turning the AC all the way up but still sweating, there could be a problem with the compressor or blower motor. Inconsistent airflow could also be caused by a clogged cabin air filter. The mechanic can quickly diagnose the issue and restore your AC’s cooling power. Strange Noises When AC Is On Your car’s AC system should run quietly. If you hear rattling, grinding, or squealing noises when the AC is turned on, there may be a mechanical issue. These sounds could indicate a failing compressor or a loose belt. Ignoring unusual noises can lead to further damage and more expensive repairs down the road, so it’s best to have the system inspected right away. Unpleasant Odors from Vents If your AC vents start emitting a musty or foul smell, mold or mildew may be growing inside the system. This usually happens when moisture builds up in the evaporator or air ducts. Breathing in mold spores can cause allergic reactions and make your car an uncomfortable place to be. A professional cleaning and inspection can eliminate odors and improve the air quality in your cabin. AC Turns On and Off Intermittently If your air conditioning cuts in and out or only works sporadically, it could be due to an electrical issue or a failing compressor clutch. This kind of erratic behavior often points to a deeper issue that needs professional attention. Getting it checked early can help prevent complete system failure and restore consistent comfort while you drive.

Your car’s cooling system plays a critical role in keeping the engine from overheating. Without it, your engine could quickly reach dangerously high temperatures, leading to major damage and expensive repairs. Recognizing early warning signs of cooling system trouble can help you avoid more serious problems. At HESCO Automotive & Performance Center, we provide expert cooling system repair in the greater Birmingham, AL area. Here are four signs of a cooling system problem. Rising Engine Temperature One of the first and most obvious signs of cooling system trouble is a rising engine temperature. If you notice that your temperature gauge is climbing higher than normal or reaching the red zone, it’s a strong indication that your cooling system isn’t doing its job. An overheating engine can quickly cause severe internal damage, so it’s important to pull over safely and address the problem right away. Coolant Puddling Below Vehicle Coolant leaks are a clear sign that your cooling system has a problem. You might spot a bright green, orange, or pink fluid (your coolant might be a different color) under your car after it has been parked. Coolant leaks can arise due to issues like a damaged radiator, cracked hoses, or a worn-out water pump. If your coolant level drops too low, your engine won’t be able to stay at a safe temperature, leading to overheating and potentially catastrophic engine damage. Visible Steam or Strange Smells If you notice steam coming from under your hood, especially after the engine has been running for a while, it's a clear warning that your engine is overheating. You might also detect a sweet, syrupy smell, which often comes from leaking coolant. These signs point to a cooling system failure that needs immediate attention to prevent further engine damage. Low Coolant Levels If you find yourself frequently needing to top off your coolant, even when you don't see obvious leaks, it’s a sign that something is wrong within the system. Sometimes small leaks are hidden, or the coolant could be leaking internally into the engine. Constantly low coolant levels should never be ignored because they point to a deeper issue that needs professional diagnosis and repair.
