Service and Maintenance
The HVAC system should be checked by a professional at least once a year, or when specified in your car’s manual. HVAC maintenance should only be carried out by professionals.
It is recommended to run your air conditioning system at least 10 minutes a month, even when the weather is cold, in order to keep the system properly lubricated.
These conditions should be immediately examined by a professional technician:
- Musty smell when the system is turned on
- Inadequate temperatures
- The car’s temperature gauge is pointing in the red zone
- Steam is coming from under the hood
- There are unusual odors either inside the car or coming from the engine compartment
