Many of us tend to overlook car maintenance. When a warning light appears on the dashboard, we may or may not address it immediately. However, car AC maintenance requires prompt attention.
When the mechanical components of your car’s AC malfunction, the AC can lose its cooling ability. This can lead to system damage, resulting in much higher repair costs than if the issue had been addressed promptly.
Read on to discover some common car AC repair myths and maintenance tips to help you understand your car’s AC system better and save money in the long term.
1. Air Conditioning Doesn’t Need Maintenance in a Closed System
This is a misconception. All mechanical equipment requires maintenance, including a brand-new car’s AC system. Even the best systems can develop issues if not properly maintained.
Some believe that regular vehicle servicing is a scam. This is far from true. The better you care for your car, the longer and more efficiently it will serve you.
2. Using AC While Driving Uphill Will Overheat the Engine
If you’ve driven through a desert, you may have seen signs advising you to turn off your AC when driving uphill in extreme heat. Although it might not seem ideal in 100-degree weather, it was considered necessary to prevent engine overheating.
While driving uphill does require more power, it is a myth that keeping the AC on will cause your car to overheat.
3. Running AC Reduces Fuel Economy
This is a widely believed myth. Many think they can save fuel by opening the windows instead of using the AC in summer.
It’s hard to say definitively whether running the AC or opening the windows has a greater impact on fuel economy. Running the AC can lower fuel economy by 1 to 4 miles per gallon, but driving with the windows down increases drag, which also reduces fuel economy.
What we can tell you is that it’s recommended to use the AC while driving in the heat. The AC reduces humidity in the car, helping the driver to see clearly and stay alert.
4. Low Refrigerant Simply Requires Topping Off
The refrigerant in your AC system is crucial for cooling. It cycles through your AC components. If your refrigerant is low, topping it off is not enough.
Low refrigerant indicates a bigger problem, like a leak or a blocked filter. If you have low refrigerant, search for “car AC repair near me” to find a professional AC repair service.
5. Air conditioning is useless during cold seasons
Although you may not use your car’s AC often in the winter, it’s important to run it occasionally, even in cold weather.
When your AC sits unused for long periods, it can develop issues. Similar to how your joints stiffen if you sit too long, your AC components can become stiff and not work properly after being inactive for months.
