Do you use AC for heat?
As a seasoned auto repair professional at Kevin's Autos, I often get asked whether the air conditioning (AC) system in a car can be used for heating. While the AC system is primarily designed to cool your vehicle, it does play a role in heating under certain circumstances. Let’s dive into how this works and what you need to know about your car’s climate control system.
How Does the AC System Work in Heating?
The AC system in your car is not directly responsible for generating heat. Instead, it works in conjunction with the heating system to improve comfort and efficiency. Here’s how:
- Dehumidification: The AC system removes moisture from the air, which is especially useful in colder months. When you turn on the heat, the AC system can run simultaneously to ensure the air inside your car is dry and comfortable, preventing foggy windows.
- Blower Fan: The same blower fan used by the AC system is also used to circulate warm air from the heater core into the cabin.
Where Does the Heat Come From?
The heat in your car is generated by the engine. As the engine runs, it produces heat, which is absorbed by the coolant. The heated coolant flows through the heater core, a small radiator-like component. When you turn on the heat, air is blown over the heater core and into the cabin, warming the interior.
When Does the AC System Help with Heat?
While the AC system doesn’t produce heat, it can enhance the heating process in the following ways:
- Defrosting: When you use the defrost setting, the AC system activates to remove moisture from the air, ensuring your windshield clears up quickly.
- Climate Control Systems: In modern vehicles with automatic climate control, the AC and heating systems work together seamlessly to maintain your desired temperature.
Tips for Using Your Car’s Heating and AC Systems Effectively
To get the most out of your car’s climate control system, keep these tips in mind:
- Run your AC system periodically, even in winter, to keep the components lubricated and prevent seals from drying out.
- Ensure your coolant levels are adequate and the system is free of leaks, as this directly impacts your car’s ability to produce heat.
- Replace your cabin air filter regularly to maintain proper airflow and air quality inside your vehicle.
Conclusion
While the AC system itself doesn’t generate heat, it plays a crucial role in maintaining a comfortable and safe environment inside your car during colder months. By working alongside the heating system, it ensures efficient defrosting, dehumidification, and overall climate control.

Frequently Asked Questions
Should you use AC with heat?
Running an air conditioner and heater simultaneously can strain your HVAC system and increase energy consumption, but it shouldn't cause damage if your system is designed to handle both functions. However, it's not an efficient use of energy. Consider using one or the other based on your comfort needs.
Is 77 degrees hot in a house?
Quick answer: The ideal house temperature is room temperature, which ranges from 68 to 78 degrees F, though this may vary from season to season. In winter, the average room temperature is generally 62 to 68 degrees, whereas in the summer, the average temperature is 72 to 78 degrees.
Can normal AC be used as a heater?
Air Conditioners can be a good choice for providing heating because they are more energy efficient than a boiler system using gas or oil*.
Is AC supposed to be on for heat?
A traditional air conditioner can only provide cooling through the refrigeration process. While some air conditioners and furnaces may share equipment, the AC unit itself plays no role in heating the home during the winter.
How do you turn the AC into a heater?
First, adjust your thermostat to your desired temperature, then switch your settings from “cool” to “heat”. You should hear the A/C fan turn off, and a separate “click” as the furnace ignites, and gas begins to flow into your heater. Give your unit about 30 seconds to achieve this.
Can we use AC in winter for heating?
Does air conditioning heat as well as cool? This depends on the particular unit you have installed in your home. If your AC is also designed to work as a heat pump, then you can use your existing unit to heat your space too. If you've got an HVAC system, this also indicates that your aircon has a heating ability.
Does an AC unit also heat?
A traditional air conditioner can only provide cooling through the refrigeration process. While some air conditioners and furnaces may share equipment, the AC unit itself plays no role in heating the home during the winter.
Can a AC be used as a heater?
Air Conditioners can be a good choice for providing heating because they are more energy efficient than a boiler system using gas or oil*.
Can I use air conditioning for heating?
Absolutely. The majority of modern air conditioners are equipped with a heating mode that allows them to provide heating as needed. This can be a highly efficient heating solution that saves you money in the long run while also ensuring unparalleled comfort.
Can AC be used as a warmer?
With the heating mode, the air conditioner can make your space warm. If you turn on the heating mode for the first 3 to 5 minutes, the fan may not work so that cold air does not flow until the air conditioner warms up.
