At Athens Auto Logic, we provide thorough inspections and diagnostics to identify heating system problems early and restore proper HVAC performance for your vehicle.
Coolant, also known as antifreeze, circulates through the engine and absorbs heat generated during operation. This heated coolant helps warm the cabin through the heating system.
The thermostat regulates coolant flow based on engine temperature. Once the engine reaches normal operating temperature, the thermostat opens and allows coolant to circulate through the system.
The heater core acts as a heat exchanger inside the vehicle. Heated coolant flows through the heater core while the blower motor pushes air across it to create warm cabin airflow.
The blower motor circulates warm air throughout the cabin using the vehicle’s HVAC system.
The cabin air filter helps remove dust, pollen, debris, and airborne contaminants from the air entering the vehicle’s interior.
Your cabin air filter plays an important role in maintaining clean airflow and HVAC system performance inside your vehicle.
A clean cabin air filter helps:
If the cabin does not warm up properly even with the heater turned on, low coolant levels or heating system problems may be affecting performance.
A failing blower motor, heater core issue, or coolant circulation problem may cause cold air to blow from the vents instead of warm air.
If the vehicle temperature gauge does not match the cabin temperature or fluctuates unexpectedly, the thermostat or related components may need inspection.
A faulty heater core or blocked coolant flow may prevent the system from producing any heat at all.
Poor airflow or uneven heating inside the cabin may indicate issues involving blend door actuators, blower motors, or clogged cabin air filters.
At Athens Auto Logic, our ASE Certified technicians provide professional heating system inspections and HVAC diagnostics for domestic and foreign vehicles. We use advanced diagnostic equipment to inspect coolant flow, heater core performance, blower motors, thermostats, cabin air filters, and related HVAC components.
