Four Reasons Your Car’s AC May Fail This Summer

The summer driving season can be ideal – long stretches of open highway with no ice or snow to stand in your way. It’s the season when many import owners fall in love with the handling and sheer drivability of their cars – and, unfortunately, the season when air conditioner failures tend to make themselves readily apparent. In a time of year when interior car temperatures can quickly top 150 degrees, this is no time to go without air conditioning.

We’ve compiled a list of common vehicle air conditioning problems Siskiyou Import tends to see during the summer months:

  1. Condenser issues. Your car AC unit’s condenser is charged with cooling hot refrigerant using the airflow that enters your car while you’re driving; if the condenser is blocked or broken, your AC will blow hot air. Often, debris from the road is the culprit in either situation – if you notice debris stuck to the grill of your car, it may be blocking airflow, and removing it will solve the problem. However, if debris has punctured or otherwise damaged the condenser, you’ll need to replace it.
  2. Compressor issues. The compressor in your car’s AC unit keeps refrigerant and cool air moving through the system – if it fails, it will need to be replaced. In some cases, you can place excess stress on your AC compressor by not using it for months and then expecting it to run at full blast once the weather warms up. To prevent this, run the AC for several minutes each month regardless of the weather to keep the system working fluidly.
  3. Cooling fan issues. The unit’s cooling fan serves to cool the condenser as it cools the hot refrigerant. However, some of the same issues that affect the condenser itself, such as road debris damage and blockage, can prevent the fan from doing its job. If your fan is cracked or otherwise damaged, you’ll need to have it replaced.
  4. Refrigerant leaks. Your entire AC system has the potential to leak cooled or hot refrigerant, and it can be difficult to locate the source of a leak. In many cases, leaks occur at hose connections and may produce oily buildup or drips from the leaking location. If you have a leak, a technician can close it by utilizing a special sealant.

Often, AC problems involve complex electrical wiring issues in addition to the more obvious causes behind the hot air. If you suspect your import’s AC system is experiencing one or more of these issues, contact Siskiyou Import to schedule a service appointment.
