I had my furnace ...
I had my furnace cleaned last year and and when they showed up one of my cats got out of where they were enclosed. I asked them to wait to start before I found him. Instead the other guy had the door wide open. I couldn't find him and they insisted in starting because they were on a "schedule". I then told them to clean up and we would reschedule. I ended up finding him in the meantime but the inconsideration was horrible. Now that it is spring our A/C isn't working. I had our usually A/C company come in. They said the furnace was very very clean but there were wires disconnected from where they would have been cleaning. So in the end my Dealfind wasn't a great deal because we had to pay to get the wires re attached. When I called to find out the exact date of when it was done I was told they have a new system and can't tell me but there should be a sticker on the furnace. And surprise surprise no sticker!! Obviously the cleaning was done well but that is about it.
