I live in a 3-story townhome. Our AC was not working, found out our compressor in the outside unit was bad (this is located under our stairs in a crawlspace, with the face of it flat against the brick outside. Hope that makes sense.
Anyway, we have a wonderful senior AC Tech who has done all our work for about 6 years now. He is wonderful, and often you have to wait for him to service things because he's so in demand (everyone else requests him too). So, no trust issues, and I trust his knowledge.
He told me I needed a new compressor, and called around for about an hour to find one he could install that day. He installed a 2 ton 1PH compressor/NCD ADD R-R-R/R-22. He did all the other maintenance with that, charged the system, etc. He was here for hours, from start to finish.
He had mentioned that this was better than our original compressor. It is working GREAT. Very cool in here, and upstairs, even on 95 degree days.
A day or so after he installed it, I noticed a rattle coming from the face of the unit outside. It kept on for days (though there is NO disruption to the effectiveness of our AC), and he came back out.
Got on his hands and knees w/ his ear to the unit, went under the crawlspace, etc. He said it may be a bearing in the compressor. I asked if the company would replace it, but he said no, not as long as it's working properly. The part is only under warrantee for a year, and I'm obviously afraid it will leave me sitting - and I sure can't afford another one!
He then put his screw driver in between the brick wall and the frame of the unit. At one point, the insertion of the screw driver seemed to dull the rattle. He said that "these units are known to rattle." I have a Bryant/carrier system, FYI.
He put something in there to soften the rattle, but it's back today louder than ever.
Should I really be satisfied with "I don't think it's an issue?" Is he right? I have trusted him in the past, but it seems odd I spend so much money on a part, then it begins to rattle. Isn't that bad, and won't that eventually contribute to some part biting the dust?
He said also maybe it needs to break in. I didn't know whether to call the company, but he said that would do no good, as long as the part is functioning.
Any advice would be greatly appreciated. Is a rattle just a rattle, or should I be worried? I do NOT want to spend thousands again next year when this may shut down right after warrantee. Seems like one short warrantee.
