Avoid common Air Conditioning problems and keep your system in top shape—even in the cold
When winter rolls in, switching off the car’s air conditioning might seem like a no-brainer. After all, you’re not trying to cool down, right? But here’s the thing—your vehicle’s A/C system isn’t just for summer comfort. Letting it sit idle for months can lead to issues that show up exactly when you need it most.
Even if you’re only driving short distances, it’s worth hitting the A/C button regularly. Modern systems are designed for all-season use and benefit from being run briefly even when heating the cabin.
Whether you’re facing foggy windows or preparing for the warmer seasons ahead, using your car’s Air Conditioning, even in cooler weather, keeps everything running smoothly.
Air Conditioning Helps Clear Foggy Windows Faster
One of the most practical reasons to run your A/C in winter is defogging. On chilly mornings, it’s common for your windscreen and windows to fog up due to moisture inside the cabin. While using the heater helps, combining it with your A/C is far more effective.
That’s because your air conditioning system removes moisture from the air. When you run the A/C alongside the heater, it produces warm, dry air that clears up glass surfaces faster and helps keep them fog-free while driving. It’s not just convenient—it’s safer, too.
It also saves you time during morning commutes and reduces the need to keep wiping down the inside of your windscreen—especially handy during school runs or early work starts.
Air Conditioning Prevents Seals and Components From Drying Out
Your A/C system relies on a refrigerant to flow through various components, keeping the internal seals lubricated. If you don’t run it regularly, especially during long winter months, these seals can dry out and crack. That often leads to refrigerant leaks, which can reduce cooling efficiency or even stop the system from working entirely when you turn it on in summer.
Running your car’s A/C once a week for a few minutes helps circulate the oil and refrigerant, keeping seals in good shape and the system ready for action when warmer days return.
It’s also a good time to check for any musty smells or weak airflow, both of which can signal that your cabin filter or evaporator may need cleaning. Don’t ignore early signs—addressing them now can save bigger headaches later.
Extends the Life of the Air Conditioning System
Like any other system in your vehicle, your air conditioning benefits from regular use. Letting it sit unused for long periods increases the risk of component failure, especially the compressor. Turning the system on periodically keeps everything moving and helps detect issues early, before they lead to costly repairs.
Plus, if your A/C isn’t working properly in winter, chances are it won’t be up to the job when summer hits. Using and maintaining it now helps avoid surprises later.
And remember, routine Air Conditioning checks don’t take long. They can be done during your scheduled service or even as a standalone visit—just ask our team when you book in.
Use It Year-Round—Your Car Will Thank You
There’s no downside to using your car’s A/C in winter. It helps keep windows clear, maintains system health, and gives you the confidence that everything’s working as it should. Even if you’re only running it briefly, regular use is better than letting it sit unused.
Winter care habits can make summer driving much more comfortable. It’s a simple step that pays off in system performance, safety, and repair cost savings.
If your air conditioning is underperforming, making odd noises, or not clearing windows effectively, it may be time for a check-up.
