How Your Car’s Climate Control System Works
Your vehicle’s AC and heating systems may feel like simple comfort features, but they rely on a network of parts that work together to regulate temperature. When one of these parts malfunctions, your entire system can stop working.
Here’s how it works:
- Air Conditioner: The system uses refrigerant, a compressor, and evaporator coils to remove heat from the cabin and circulate cool air through the vents.
- Heater: The heater relies on the engine’s coolant and a heater core to generate and distribute warm air into the cabin.
- Blower Motor: Pushes air through the vents, controlling the intensity of airflow.
- HVAC Controls and Sensors: Allow you to adjust temperature and fan settings while maintaining proper balance.
If any of these components fail — whether it’s a refrigerant leak, worn-out compressor, or faulty thermostat — your AC or heat will struggle to function properly.
Signs You Need AC or Heater Repair
Knowing when to schedule an inspection can save you from costly repairs later. If your car’s cabin comfort isn’t what it used to be, there’s a good chance your climate system needs attention.
Common signs your AC or heater needs repair include:
- Air isn’t cooling or heating as it should
- Weak or no airflow from the vents
- Foul or musty smell coming from the vents
- Clicking or rattling noises when turning on the fan
- Foggy windows that won’t clear properly
- Refrigerant or coolant leaks under the vehicle
- AC only works when driving, not when idling
If you’ve noticed any of these symptoms, visit Dastgah Tire Pros & Service for a full system inspection. We’ll pinpoint the issue and get your climate control system working perfectly again.
Auto AC Recharge and Repair
Your car’s air conditioner depends on refrigerant to remove heat and keep the air cool. Over time, refrigerant levels can drop due to leaks or natural loss, reducing cooling performance.

- Refrigerant recovery and recharging
- Compressor inspection and replacement

Importance of Regular AC & Heat Maintenance
Routine maintenance is key to keeping your vehicle’s HVAC system running efficiently. A small refrigerant leak or low coolant level might not seem urgent, but ignoring these issues can lead to compressor failure, clogged heater cores, and poor air quality.
Benefits of regular climate system maintenance include:
- Improved cabin comfort and temperature control
- Better fuel efficiency
- Longer lifespan for AC and heating components
- Prevention of costly breakdowns
- Cleaner air inside your vehicle
At Dastgah Tire Pros & Service, we recommend having your AC and heating system inspected at least once a year or before each summer and winter season.

- Low refrigerant or coolant levels
