The service was prompt and the tech was professional. However, after reviewing the pricing on parts and labor, I realized I was charged significantly higher than typical market rates for several items. I’d recommend getting a full, itemized estimate beforehand and comparing prices if possible. Otherwise, the job itself was completed properly.
