Who's qualified Ask for proof of insurance, relevant certifications (e.g., ASE for auto repair), and any license your state or city requires.

What should I do today if my car is overheating?

Turn off the A/C and turn on the heater to pull heat away from the engine. Do not open the radiator cap while the engine is hot. Schedule an early-morning visit if possible, since Boise heat builds quickly after sunrise.

What should I ask for in the quote?

Ask for a written, itemized estimate before any parts are replaced. Ask whether the visit includes pressure testing of the cooling system. Keep the work order, parts list and final invoice for your records.

How do I verify the mechanic before hiring?

Idaho does not require a state-issued general mechanic license, so ask the pro for proof of insurance and ASE certification. Confirm the person or business is properly registered to do auto repair work. If A/C work is needed, verify EPA Section 609 refrigerant certification.

Why does overheating get worse in Boise summers?

Boise has a high-desert climate where days heat quickly. Average July and August highs are in the lower 90s, and the valley exceeds 100°F almost every year. Heat, not rain, drives overheating risk here.

What to do next

  1. Ask the pro to pressure test the cooling system during the diagnostic visit.
  2. Request an itemized written estimate before authorizing any parts replacement.
  3. Verify insurance and ASE certification, and confirm EPA Section 609 if A/C work is involved.
  4. Keep the work order, parts list and final invoice together for your records.
  5. Call (208) 795-9673 or email [email protected] for a free quote from an independent, insured mobile mechanic.
