New to Seattle and was hoping to find a good service I can use for future. Saw them very close and has some good rating. However, I got the same experience as Russ who commented 8 months ago. They quote $700+tax for thermostat replacement, where the new part can be bought at around $100 and it won't take more than 1 hour labor. I refused the repair the moment I got the quote. They must have realized that I am not the one knows nothing and won't be repairing here, and charged me $312 for diagnosis, also warned me not to bring to dealers for repair -- in fact, they charge way more than dealer already. Glad I stopped my loss by only spending $312 for no heat inspection! (sarcasm) And the $312 diagnosis doesn't come with error code, which I believe is next level specialists that we ordinary people won't understand.
