Asheville’s four seasons are undoubtedly one of the benefits of living in this area. But North Carolina summers can be hot, especially if your car’s air conditioning fails. This is why many area residents trust Cox Auto Service on Druid Drive for their car AC repair.
Your car’s air conditioning system contains many working parts. These include a compressor, expansion valve, and two heat exchangers. The system also requires refrigerant fluid. Failure of any of these parts can lead to cooling problems. Below are some of the most common reasons why people need trusted car AC repair.
No Cold Air Flows from the AC
A refrigerant leak often causes the cold air to stop flowing from a car air conditioner. Without this important fluid in its system, the AC components stop working and you need car AC repair. A leak can occur for many reasons. The most common cause is a hole in one of the AC’s main parts, such as:
To fix this problem, your trusted mechanic at Cox Auto Service adds a fluorescent leak tracer dye and refrigerant to your AC system. While the air conditioner runs, they use a blacklight to find the leak, then repair, evacuate and recharge your AC.
Air Does Not Flow through the Vents
Several component problems can cause air to stop flowing through your car’s vents. This type of car AC repair requires the skill of a knowledgeable technician, starting with diagnostics. Parts checked for this repair include:
- Fuses and relays
- Blower motor and blower resistor
- Air intake vents
- Belts and hoses
The technician typically starts repairing the AC with this problem by replacing fuses and the relay. From there, they can eliminate this quick repair issue if the air still does not flow as it should. Bigger problems generally require repair or replacement of non-working parts.
The AC Does Not Cool Enough
Low refrigerant causes air conditioning to get cool, but not cold enough. Other reasons for only slightly cool air from your AC can include a blocked or failed condenser or a failed clutch switch. To solve your car’s problem, the technician tests these components. He or she looks for damage, blockages in the system or part failure before starting your car AC repair.
A Mildew Odor from the AC
If you smell the noxious odor of mildew coming from your AC, you have bacteria growing in your system. Older vehicles and those where the AC is rarely used generally have this problem. It can also happen in vehicles frequently set for maximum cooling since excess moisture builds up in the unit during operation at this level.
For this car AC repair, you need the air filter replaced. This can fix the problem. If it does not, the technician must add an anti-bacterial fluid that clears contaminants and kills mold in the system.
The AC Makes Noise
If you turn on your car’s AC and hear odd noises like banging or rattling, this signals a problem. Sometimes the issue is simple, like leaves or other debris blocking the unit. But you may have a bigger issue, such as a worn-out bearing that grinds or squeals or a failed compressor clutch that rattles.
This car AC repair starts with inspection by a trusted technician. During this inspection, the auto mechanic can find which component is failing to replace it.
Water Dripping Onto Your Floorboards
Water dripping on your car’s floorboards from the AC generally means a chain of problems. These start with build-up of bacteria on the evaporator coil in the AC heater box under the dashboard. This bacteria combines with condensation and creates a slimy film that accumulates on the AC fins. Over time, the film clogs the drain line and causes water from condensation to drip onto your vehicle’s floor.
For repair of this problem, the technician first determines what is clogging the drain line and why. He or she then repairs or replaces the hose to fix your AC and get you back on the road in cool comfort.
AC Switching from Cold to Hot
When you turn on your AC, the last thing you expect is for it to blow hot air. This sometimes happens with a failed expansion valve. The expansion valve must properly dispense refrigerant to the evaporator for proper AC cooling. A blocked valve prevents this and can freeze from resulting moisture.
For this car AC repair, your auto technician tests the system’s pressure. He or she also inspects parts for malfunctions or blockages for proper diagnosis. If your car needs repair or replacement of these parts, they fulfill those needs.
