Reasons for Car AC Failure

A/C Failure

As we approach the summer, your vehicle’s air conditioning (A/C) system becomes that much more important. Not only does your car a/c work to keep the interior of your vehicle cool; it can be a contributing factor to vehicle failure if all of the working components aren’t maintained.

Common Problems Associated with Car A/C Failure

#1 – Overheating

According to the Chicago Tribune, overheating is one of the most common reasons for vehicle failure. Most common during the warmer months, overheating may be due to a faulty cooling system or low levels of fluids.

Consider the fact that your car has to work that much harder during the summer months, for example, to keep your engine from overheating. Therefore, always be sure that your vehicle’s fluids are topped off and changed regularly. If your vehicle does overheat, turn off your car a/c, and turn on your heat instead.

#2 – Weak Air Flow

If your car’s A/C isn’t producing as strong of an airflow as you’d like, it may be due to a number of issues, including: Mold & Mildew Accumulation, Loose Hose, Broken Ventilation Fan, Improper Seals. If you notice any of the previous issues, schedule an appointment immediately before further damage is caused.

#3 – Leaks

Issues with your car’s air conditioning system may be due to a leaking component. If you discover any leaks in your car’s a/c system, be sure to have it looked at by a certified mechanic.

According to the U.S. Environmental Protection Agency (EPA),

By stopping the leak, you will prevent refrigerant from leaking into the atmosphere. The refrigerant in older vehicles is CFC-12 (also known as Freon, a brand name), which is no longer manufactured in the United States because it depletes the ozone layer. As nationwide supplies dwindle, it is becoming increasingly expensive to purchase CFC-12, so that fixing a leak may be more economical in the long run than continuing to purchase CFC-12.

#4 – A/C Compressor

Problems involving the air conditioning in your car may be directly related to a faulty A/C compressor. Your vehicle’s compressor is, arguably, the most important component of a car’s A/C system. It’s responsible for putting refrigerant under pressure prior to pumping it into the vehicle’s condenser, where it converts from a gas into a liquid.

According to

A fully functioning compressor is necessary for the air-conditioning system to provide peak performance. On most cars, A/C compressors are driven by an engine-accessory belt. If the belt is worn and slips, the compressor won’t operate at full strength. Compressors can also leak refrigerant, resulting in less cold air going into the interior. Internal parts can also fail, leading to no cold air.
