Why Isn’t My Auto A/C Cooling? 

Here’s What Could Be Wrong 

Keep Your Cool 

As temperatures rise, there's nothing worse than hopping into your car only to find that your A/C isn’t cooling correctly. At Z’s Car Care in Hillsboro, OR, we understand how uncomfortable this can be, especially during the sweltering summer months. If your air conditioning isn’t keeping you cool, it could be due to several reasons. Let’s break down some common issues that might be causing your A/C to blow warm air instead of a refreshing breeze. 

Common Auto A/C Issues 

Low refrigerant levels are the most common reason your A/C may not be cooling effectively. Refrigerant is the substance that allows your A/C to cool the air. Over time, your A/C system can develop leaks, causing the refrigerant to deplete. If your system is low on refrigerant, it won’t be able to cool the air properly. Our ASE-certified mechanics can perform a quick diagnostic test to check for refrigerant leaks and top up your refrigerant if necessary. A clogged or dirty cabin air filter can restrict airflow, reducing the effectiveness of your A/C. Air filters trap dust, dirt, and other debris, but they can become blocked over time, preventing fresh, cool air from circulating. A simple air filter replacement is affordable and an easy fix. We recommend this service during routine maintenance. The compressor is the heart of your car’s A/C system. It pressurizes the refrigerant and circulates it through the system. If the compressor is malfunctioning or broken, your A/C system may not work at all. Symptoms of a failing compressor include strange noises or the A/C blowing warm air. We specialize in diagnosing and repairing compressor issues to get your car's A/C back up and running. The A/C condenser is responsible for releasing heat from the refrigerant. If it becomes blocked or dirty due to debris like leaves or dirt, the system will struggle to release heat, reducing its cooling efficiency. Cleaning or replacing the condenser can restore your A/C’s cooling ability. The rubber hoses that carry refrigerant can crack or become damaged. If these hoses leak, your A/C will lose pressure and won’t cool the air properly. Our auto A/C repair experts can inspect the hoses for leaks and replace any damaged ones.
