Auto AC Repair
Why is it that an auto AC repair project always seems to hit your car on the hottest day of the year? For many drivers, a car’s air conditioning system is taken for granted. It’s a modern convenience that, in many areas of the country, has become a necessity. If your AC is not working correctly, then it could be the result of a number of engine problems. To learn more about the most common types of AC repairs and their causes, continue reading below:
Auto Air Conditioning Systems
Before you learn how a car AC system malfunctions, it is beneficial to understand how an AC system works. At the core of your car’s AC system is Freon. This liquid is pumped through a series of pipes and tubes via an air conditioning compressor. As the compressed fluid moves along its path, it gets pushed through an expansion valve. This expansion valve causes expansion and contraction of the Freon gas, which causes the gas to rapidly cool down.
Once passed through the expansion valve, the cold Freon gas makes its way to an evaporator core, which in turn sends the cold air to the vents in your car’s interior. An AC blower situated just behind the vents helps properly dissipate the AC throughout the cabin.
Common Auto AC Repair Problems
If your car’s air conditioning isn’t adequately cooling your cabin, then it could be the result of several issues. Some of the most common causes include:
- Lack of air flow: Low air flow within the AC unit will result in insufficiently cooled Freon. Common causes of low air flow include a broken fan motor or defective relays and switches.
- Low Freon levels: Inadequate levels of Freon in the AC unit can cause cooling problems. Low coolant levels are frequently caused by leaks in hoses or tube connections. If a puddle collects under your car after adding Freon, then you know a leak is the cause of your problems.
- Overheating: A vehicle that has trouble managing engine temperature can cause insufficient AC cooling. If such is the case, then it may be that one of your vehicle’s electric cooling fans has malfunctioned.
Repairing Auto AC
If you find that your AC auto repair is not an easy fix, then it is likely time to contact an experienced AC repair technician. Oftentimes, AC repairs are not incredibly complex, and can be completed by any competent automotive repair expert. However, if your car is fairly new, you might consider taking it back to the dealership for repairs. Some AC repairs are covered under warranty, meaning you might be able to get the problem fixed for free.
