FAQs About Car Heater Repair in McKinney, Texas
Why is my heater blowing cold air?
This could be due to low coolant, a clogged heater core, or a faulty thermostat. A professional car heater service can identify the issue.
How much does heater repair cost?
It depends on the problem. Simple fixes like a coolant flush cost less, while heater core replacement is more involved. We provide upfront estimates.
Can a bad heater cause engine problems?
Yes. Since your heater is connected to the cooling system, issues like low coolant or clogged hoses can lead to engine overheating.
Why does my car smell sweet when the heater is on?
That’s usually a sign of a coolant leak, often from the heater core. It needs immediate attention.

How long does heater repair take?
