In reading the reviews before me, other people have experienced the same issues we have with Orangutan. They are always pushing repairs we do not need. The last time they were here, they gave us a quote of around $2500 for various repairs. We got suspicious so had another company come out and give us a second opinion. They said our unit was fine and working properly. I just got another opinion today from a large Phoenix area company and they said everything was fine.
They also talked us into getting our ducts foam sealed and I certainly wish we would've gotten a second opinion. We went ahead and let them do that. It really has not saved our energy costs. In retrospect, it probably was not necessary.
So take our advice and stay away from Orangutan!
