Why Running Your Car’s A/C in Winter is a Smart Move

While it might seem counterintuitive, running your car’s air conditioning system during winter can actually save you money on maintenance and repairs. Most experts advise against ignoring your car’s A/C during colder months, and here’s why.

Below are 5 key benefits of keeping your car’s A/C active even in winter.

1.Prevents Component Seizure

The air conditioning system contains various components, such as the compressor, seals, and hoses, that can deteriorate or seize up if not used regularly. Running the AC periodically helps keep these components lubricated and in good working condition.

2. Defogging the Windshield

Modern car HVAC systems often use the air conditioning system to help dehumidify the air when defrosting or defogging the windshield. By running the AC, moisture is removed from the air, which helps to quickly clear condensation from the windows and improve visibility.

3. Maintains Refrigerant Levels

The refrigerant in the AC system contains lubricants that keep the internal parts of the system in good condition. Running the AC circulates the refrigerant and these lubricants, which helps to maintain the seals and prevent leaks.

4. Improves Air Quality

Running the AC periodically can help reduce the buildup of mold and mildew in the system. These can form in the evaporator core when the system is not used for long periods, especially in damp conditions. By running the AC, you help keep the system dry and reduce the likelihood of mold and mildew growth, which can improve the air quality inside your car.

5. Ensures System Functionality

Regularly using the AC in winter ensures that it will function properly when you need it during the warmer months. This helps you identify any issues early on, so they can be addressed before the summer heat arrives.


Though it may seem tedious, running your car’s air conditioning system regularly, even at a low temperature, can significantly benefit your car’s overall condition. Moreover, it helps you avoid unnecessary expenses on repairs and services, ensuring your car remains in top shape throughout the winter months.
