DON'T CALL NORM!!! When he was late arriving, I called for an eta. He told me I was late (i'm calling from home 30 minutes after the appointment time, who's late?). I asked if he still planned to come out, it was 92 in the house and i have a MEDICAL CONDITION......Norm's response???? HE LAUGHED AT ME!!!!! I'd rather sweat in the house ANY DAY before having an unscrupulous A/C repairman INSULT ME. Call someone else, and avoid his childish behavior.
