How to Keep Your Vehicle’s Air Conditioning System Running Smoothly
Your vehicle’s air conditioning system is crucial to ensuring your comfort during drives, especially during the summer. However, like any other part of your car, your AC may start to malfunction when it doesn’t get regular care and attention to function at its best.
Over time, the system can experience wear and tear, which can lead to decreased performance or even failure. If you want to avoid these issues with your air conditioning system, make sure to invest in regular maintenance and get your vehicle inspected every few months.
In this guide, we’ll list some key steps to help keep your vehicle’s air conditioning running smoothly. With a little proactive care, you can ensure a consistently cool ride all year round so without further ado, let’s get started:
Make Sure to Turn It On Regularly
It might seem counterintuitive, but using your air conditioning system even during the cooler months can help keep it in working order. Running the AC for 10–15 minutes every few weeks allows the system to circulate refrigerant and lubricate the moving parts.
While it may be hard to believe, this simple step can go a long way in preventing the seals from drying out and avoiding a buildup of moisture that could lead to mold growth inside the system.
Frequently Check the Refrigerant Levels
One of the most common reasons an AC system stops working efficiently is a low refrigerant level. The refrigerant, or coolant, is the substance that absorbs heat and cools the air inside the cabin.
If the refrigerant is low, your AC will struggle to produce cold air. While it’s not always easy to check refrigerant levels on your own, most vehicle manufacturers recommend having your system checked regularly by a professional.
If you’re experiencing weak airflow or warm air blowing from the vents, it could be a sign that the refrigerant needs a top-up. When this happens, reach out to an auto repair professional to get your system thoroughly inspected. Expert mechanics will be able to diagnose and repair your air conditioning before the problem gets out of hand.
Replace the Cabin Air Filter
The cabin air filter is responsible for removing dust, debris, and pollen from the air before it enters the cabin through the AC system. Over time, the filter can become clogged with dirt, which can restrict airflow and reduce the efficiency of your AC. Most manufacturers recommend changing the cabin air filter every 12,000 to 15,000 miles, but it may need to be replaced more often if you live in a dusty or polluted environment.
Replacing a clogged filter can help improve the air quality in your car and restore optimal airflow. Hence, make sure to get your air filter replaced in time to keep your car’s air conditioning working at its best.
Avoid Overloading the AC System
Running the AC at maximum power for long periods can cause undue strain on the system. When you’re in heavy traffic or idling for extended periods, consider turning off the AC to give the system a break.
Also, avoid using the AC when you’re parked with the engine idling. Instead, open the windows to let the heat escape before you turn on the AC. Small measures like these can go a long way in improving the efficiency of your air conditioning system.
Keep the Condenser Clear
Over time, dirt, leaves, and other debris can accumulate on your car’s air conditioner’s condenser and restrict airflow, causing the system to overheat and perform poorly.
To avoid the problem, regularly inspect the condenser and clear away any debris. If you’re not sure how to access it, have a mechanic clean it during routine maintenance. They will inspect for any signs of debris on the condenser and provide immediate repairs and cleaning.
Use the AC in Recirculation Mode
When you’re running the AC, use the “recirculation” mode instead of “fresh air” mode. This keeps the air circulating within the cabin, which makes it easier for the system to cool the air and reduces the load on the compressor.
Fresh air mode brings in outside air, which may be hotter and more humid, making the system work harder. By choosing recirculation, your AC will operate more efficiently, and the cabin will cool faster.
Don’t Ignore Common Warning Signs
It’s important to keep an eye on how your AC is performing to catch potential problems early. Some common warning signs include:
Weak airflow: This could indicate a clogged filter, blocked vents, or issues with the blower motor.
Warm air: If your AC blows warm air instead of cool, it could be due to low refrigerant levels, a faulty compressor, or a clogged condenser.
Strange noises: Squealing, rattling, or clicking sounds could point to a problem with the blower motor, compressor, or other parts of the system.
Unpleasant smells: If you notice musty or moldy odors, it could be a sign of mold or mildew growth inside the system.
If you experience any of the above issues, it’s wise to take your car to a qualified mechanic who can diagnose and fix the problem before it worsens.
Schedule Regular AC Maintenance
Just like your engine or brakes, your vehicle’s air conditioning system benefits from regular maintenance.
Schedule a check-up every year, or at least every two years, to ensure that everything is functioning as it should. A professional inspection can detect issues before they become serious problems and help keep your AC system running smoothly for longer.
A typical maintenance service might include checking refrigerant levels, inspecting the compressor and hoses, and verifying the condition of the cabin air filter so make sure to be on top of these maintenance steps.
