I came to do two ac tund ups. The upstairs ac had a 37degree temp split. Filter was dirty. He wants to buy his own. Contactor has lots of pitting. He wants to wait on that. Downstairs unit is noisy. Recommended a hard start and ac renew. He did not want to do that today. Downstairs ac ready to run this year. Upstairs unit needs a new filter. It is not ready to run this year without a new filter.
