Auto Air Conditioning Repair
Kentucky has one of the most drastically changing climates in the US. Warm weather or cold, Lexington drivers still need to think about their vehicle’s air conditioning. Working up a sweat is a great thing to do in a gym around Lexington, but not in your car. When your car’s AC system has a problem, you’ll often feel it right away. Do you hear loud noises under the hood when you turn on your air conditioner? Do you only get cool air sporadically or no cooling at all out the vents? If so, it’s time to get your air conditioner checked. Keeping your AC system well maintained can help prevent expensive repairs. Be aware of early warning signs like; an unusual noise when the AC cycles on or the air not cooling like it normally does.
Air conditioning service at Auto Tech Service 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. The most preventable problem with air conditioning is related to airflow on your car. The largest component of the air conditioning system is the ac condenser, which is located in from of the engine radiator, and often gets leaves, dirt, trash bags and other road debris blown against it (inside of your car’s grill) and that restricts the air that passes through it; that air is what cools the system back down after sucking all of the heat out of the inside of your car. Then a performance test determines if the system can hold vacuum. If it can, then the system is evacuated to remove any old refrigerant and recharged with clean, fresh refrigerant. With the huge improvement in manufacturing processes, and the heavy restrictions imposed by the government, modern systems should be able to hold the refrigerant in the system indefinitely. But failures do occur. We see many cars from the early 90s still arriving in our shop on their original charge. An ultra violet dye is added to the system for leak identification. A final test ensures the vehicle’s air conditioning is outputting a good vent temp and working properly. Many times small leaks will not be detectable on the first visit. If cooling does diminish the dye we installed will help us identify quickly where the leak is and make necessary repairs to your system. It is often these same leaks that lead to the most dreaded component failure: the AC compressor. As the refrigerant leaks out of the system, so does the ac oil that circulates through the entire system which keeps the ac compressor lubricated. Once low on oil the compressor bearings will fail which leads to a very thorough and expensive repair, and a repair that often can be prevented.
New environmental laws have stopped the manufacture of Freon, a refrigerant that was common in cars made before 1993. If you have an older vehicle that uses Freon, we can retrofit your system to use R134-A Refrigerant. It will pay for itself in the long run. So, if your AC is just a lot of hot air, bring it in to Auto Tech for your Auto Air Conditioning Repair.
Now here’s a auto AC tip for Lexington drivers: You should run your air conditioner every so often during KY winters. This circulates the lubricant to help keep the seals from drying out.
In addition to proper AC performance, there’s one more thing that is directly related to air conditioning service and will impact the quality and volume of air moving inside in your vehicle. 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, so ask your Auto Tech Service service adviser to check your cabin air filter at the same time they’re doing your air conditioning service. Not all cars have a cabin air filter but most newer vehicles will. Next comes the cabin air filter, which most cars being made today have.
