Air Conditioning Repair
Much like your refrigerator or the A/C unit in your house, your car’s air conditioner uses a cycle of compression and expansion (and condensation/evaporation) of refrigerant to provide chilled air. Your refrigerator, however, isn’t subject to the vibration and extremes of temperature that your car’s A/C experiences. Just like anything else on your vehicle, your automotive air conditioner will wear out and degrade over time. Hoses start to crack and dry out, O-rings dry out, shrink and leak and mechanical parts can eventually fail. It’s estimated that even a good, healthy A/C system on a late model car will seep out 5-10 percent of its refrigerant over the course of a year. At Black’s Tire & Auto Services, we’ve got the training and experience to diagnose and repair any problems your car’s A/C system might encounter.
What are some symptoms of air conditioning problems?
- Air from the A/C vents has a musty or foul smell
- Air is barely cooler than ambient air outside, or heat isn’t adequate
- Air feels moist and humid
- A/C only blows cold while diving – not while idling or parked
- A/C vents never seem to blow enough volume of air, even with fan all the way on High
- Metallic clicking sound from under hood at regular intervals, as the A/C compressor’s clutch cycles the unit on and off due to low refrigerant
More often than not, the problem with automotive A/C comes from simply being low on refrigerant. We can recharge the system using a refrigerant that includes a lubricant to oil the compressor and condition O-rings and seals. The refrigerant also includes a dye that makes it easy to spot any leaks around seals or other parts. Sometimes weak A/C performance is the result of moisture in the system that causes a freeze-up on the evaporation side – our techs can purge the system of moisture using a vacuum pump, which also flushes out any sludge or contaminants.
Remember – the longer you let A/C problems go (especially continuing to use the system with low refrigerant), the more complicated and expensive they can become. Make an appointment with any of our Black’s Tire & Auto Service locations across North Carolina and let us help you keep your cool.
