FAQs About Heater Repair in Seaside, CA

Why is my heater blowing cold air?
This could be due to low coolant, a clogged heater core, or a faulty thermostat. A full auto heat service will identify the issue.

How much does heater repair cost?
Costs vary depending on whether you need a simple coolant flush or a major repair like a heater core replacement. We provide upfront estimates.

Can a heater problem cause my engine to overheat?
Yes. Since the heating system is connected to your car cooling system, issues like low coolant or clogged hoses can cause overheating.

Why does my car smell sweet when I turn on the heater?
A sweet smell often indicates a coolant leak, usually from the heater core. This requires immediate attention.

It’s recommended to flush the heater core and coolant system every 30,000–50,000 miles, depending on your vehicle and driving habits.
