* Our flat-rate service fee includes the trip charge and diagnostic fee only. It can be viewed only if you follow repairs with us. Here at ProFIX, we don’t work by hours but you pay by the job and never pay overtime or hidden fee. We use cutting-edge tools for diagnostic appliances, so we provide quotes as accurately as possible. It doesn’t matter if the repair will take half an hour or two hours, you will never foot the bill when jobs take longer than expected.
