My AC unit has settled.

OK guys, the company called and said there would be a service charge to look at it and it was doubtful that it was covered. So we pried one side up an inch with a very large solid steel one inch bar and a 6 foot pry bar. We placed about 3 short boards along the rail between the pad and the unit. It was very hard to pry up the side that was attached to the duct. A 4' carpenters level says it is level and the filter area straightened out and the filter slides easily in and out. I think it is good but will keep an eye on it.
I would never have been able to lift the pad without damaging it. I know some of you probably could have.
Thanks. There is a fan that runs after the furnace shuts down. It is not the squirrel cage fan but very near the intake and exhaust ducts by the sound. It became loud when shutting down recently and I had hoped that straightening the unit might help it but it is the same. I think that that fan or is not used for AC so I'll try to save enough to have it serviced during the summer. I don't know enough to get into it. I can change the filter now.
