I called Hobaica because they advertise on the back of my church bulletin. We had what I thought to be a simple problem with the condensation line backing up. Hobaica sent their tech, Anthony, to our house the next day for the $19.52 special, which included a 16 point inspection. Turns out the condensation line was just clogged. He cleared that up, put in a new air filter for us and that was it! No surprises or extra services we didn't need. I would recommend them to anyone!
