A properly functioning heater keeps you comfortable and safe during cold weather, and also helps defrost your windshield for clear visibility. If your heater isn't performing, have it inspected before winter weather makes driving uncomfortable or unsafe.

Comprehensive Heater System Inspection

Before recommending any repairs, we perform a thorough inspection of your entire heating system. We check coolant level and condition, thermostat operation, heater core flow, blend door function, and blower motor performance to identify the source of your heating problems.

Blower Motor Replacement

If air isn't flowing from your vents, the blower motor or resistor may have failed. We diagnose and replace blower motors and resistors to restore proper airflow at all fan speed settings.

Heater Core Repair and Replacement

A clogged or leaking heater core is a common cause of no heat. We flush clogged heater cores when possible or replace failed units to restore warm airflow to your cabin and eliminate coolant leaks and odors.

Blend Door and Actuator Repair

Blend doors control the mix of hot and cold air entering your cabin. When actuators fail, you may get only hot or only cold air, regardless of temperature settings. We repair or replace blend door actuators to restore proper temperature control.

Thermostat Replacement

A stuck-open thermostat prevents your engine from reaching proper operating temperature, which means your heater can't produce warm air. We replace faulty thermostats to restore correct engine temperature and cabin heat.

Coolant Flush and Fill

Low or contaminated coolant reduces heater performance and can damage your heater core. We flush your cooling system and refill it with fresh manufacturer-recommended coolant to ensure proper heat transfer and system protection.
