Well, where to start. Our unit started to blow warm air and we called Just Air as we had their card. They advised use that they would be available the next morning between 9-12. That was a bit later than we would have liked but we made arrangements. My wife decided to do some work from home and wait for the appointment but had to get out by 1:00 at the latest. Around 11:30 my wife tried to call Just Air for an update as she hasn't heard anything. It kept going to their massaging until around the third time she called. The person she spoke with said they would try to get an ETA on his arrival. There was never a response back until the guy actually arrived at 12:15, fifteen minutes after the appointment window. The service person apologized for running late and won't to the back to take a look. Upon a quick look he said we were running low on freon and was looking for a leak and would then check for pricing once the diagnosis was complete. It was at this point that my wife called me as she feeling like she was going to run late for an important appointment and was concerned about this guy's knowledge. I had to leave work so sure wouldn't miss out on her meeting. It took me about a half hour to get back and upon arriving the service tech was walking out. He had advised my wife that he couldn't find the sound of the leak and would have to call out another guy with equipment to find the source and that would cost an additional 200 dollars. My wife called to speak with a manager for further insight to why there was an additional charge and after a short discussion and ended up along the tech to leave the house and we declined further service from them. To Just Airs credit, they did apologize for the incident and didn't charge us for the service call.
