A/C started making rough noises today. What should I check?

It seems to be working fine but it's running very rough. I am currently in a very rural area and didn't plan on leaving for a week or two. Any ideas on what to check? It seems to be producing cool air but it sounds like a loud engine running or something along those lines.
  • Look for the nests like r luver suggested, mine was same, and I took a wooden ruler to knock it loose without removing cover . Then I shot something like wd40 in there and took the ruler and gave it a hard spin yturn. Removed ruler n turned it back on and it ran like a charm. I also have heard of small squirrel nests too in there
  • Remove the cover and I will lay money on the table that you will see a mud-daubers nest on the fan hub. Same thing has happened to me. Once at home the other on arrival in Charleston SC. It's a quick fix if that's what it is. They will build one Especially if it's been sitting unattended and off.
  • Depending on the AC model, you might check the distribution fan. The Carrier Air V have had problems and no parts available.
