Why isn't your car AC blowing cold? π₯΅
60% of the time, it's just a leak. Not a new compressor. Not an $1,800 rebuild.
I'm Fernando Gomez, owner of Rohnert Park Transmission & Auto Repair. 28 years fixing cars in Sonoma County β Rohnert Park, Cotati, Santa Rosa, Petaluma, Healdsburg, Windsor, Sonoma, Penngrove, Sebastopol, Bodega Bay, and beyond.
This carousel ranks the 5 most common causes of car AC failure (with real cost estimates) so you don't get ripped off this summer:
β 60% β Low refrigerant from a leak ($200-400)
β 15% β Compressor failure ($800-1,500)
β 10% β Clogged condenser ($50-400)
β 8% β Electrical failure ($40-400)
β 7% β Blend door actuator (varies)
The ONE question that protects you from overpaying: "Did you do a dye test before recommending a compressor?"
If they say no β get a second opinion.
