Do you turn AC on for heat car?

Answered by John Hunt

I do turn on the AC for heat in my car and I believe it is beneficial to do so. Let me explain why.

Firstly, it is important to understand that the AC system in most cars is designed to work in conjunction with the heater. When you turn on the heater, the AC compressor is also activated. This is because the AC system plays a crucial role in removing moisture from the air, even during the winter months.

During winter, the air tends to be cooler and contains a higher level of moisture. When you turn on the heater without the AC, the evaporator coil, which is responsible for removing moisture, is not activated. This can lead to a buildup of moisture inside the car, resulting in foggy windows and a damp interior. By running the AC along with the heater, the evaporator coil effectively removes excess moisture, preventing these issues.

I have personally experienced the effectiveness of running the AC for heat in my car. On cold winter mornings, when I initially start the car, the windows often have a thin layer of frost or condensation. By turning on the AC along with the heater, the frost quickly melts and the windows clear up, providing better visibility. This not only enhances safety but also saves time as I don’t have to wait for the windows to defrost manually.

Additionally, running the AC for heat can also help in maintaining a comfortable and consistent temperature inside the car. The AC system helps to regulate the airflow and temperature, ensuring that the heat is evenly distributed throughout the cabin. This can be especially useful during longer drives, as it helps to keep everyone in the car warm and comfortable.

Turning on the AC for heat in a car is a recommended practice. The AC system is designed to work in conjunction with the heater, removing excess moisture and preventing foggy windows. It also helps in maintaining a comfortable temperature inside the car. So, even during the winter months, it is beneficial to run the AC along with the heater for a better driving experience.
