I have had a less than great experience with Cool Temp Air. Last time I used them, Charles came to a rental unit to try to fix a furnace that he said was broken. I paid a lot of money to try to have it fixed, but the experience itself was confusing (there were problems with the furnace that I needed to know ahead of time, but didn't) and I am not sure he understood how to resolve the problem so that I would be a happy customer. The worker didn't seem too knowledgeable about his work during this visit. This time, I ended up using their service again and everything turned out okay. We found out that there was a leak problem in the air conditioning unit. It ended up not working at first, so the worker came back again and it turned out there was another problem with it. In the end, it ended up working, so I was pleased about that. So overall, last time I had a very poor experience with the company, but this time, it was okay - so I had very inconsistent experiences with them.
