I had a bit of a mix-up when I last tried to use Opie's One Hour Heating and Air Conditioning. I took a picture of the part that needed to be replaced and asked them to call me before coming out to avoid making two trips. However, I never got the call back from them. As a result, the tech showed up at my front door without the part. I got charged $149 for a service trip, with a return trip due the next day when they got the part. Opie's says that they tried to call me, but my voice mailbox was either full or not set up. My voice mailbox is set up, and it is not full, so it looks like maybe they called the wrong number. Whatever, after I told them this, they are supposed to return my check to me. So, because of this mix-up, I am just rating them at average, or Three Stars.
