First a mont ago the air would not work. The employ said the reason it did not work is because filter would not work. Since the unit is in the is in the attic the unit started to leak. The second person came in said he had to come back. He came back and just put a piece of wood to raise drain pipe of course that did not work and it continued to drip but worse. The ceiling fell. Then they said they had to replace several things and they would come back the next day. He did not show because he did not have the material. He came back "fix" it and did so but forgot to attach drain pipe properly another leak. They cam and fixed it again. Of course still leaking and now it is the drain pan. They did not order the part right away. So I will have to wait another three days without air. The managers response: you have only been without air for three days. Do not use this company
