As your patient was told by her ObGyn, it is safe to use combined birth control pills and Mirena at the same time and this practice may be helpful with regard to the irregular bleeding, prolonged bleeding, cramping or pain that can be associated with Mirena in the first months after Mirena insertion.
RE: AC compressor cycling. IP: Logged. Message: I have an '03 QC 4.7 v8 and the a/c unit will cycle when it's set to defrost and high heat on the temp gauge, a/c off. I read a post last night that talked about pulling the a/c defrost fuse # 24 (on the my truck) during the winter months to keep the a/c from cycling.
As it gets cold the heat pump defrosts plus calls for the resistance heat to supplement. I left the heat pump on all year last year as that is what I had been told by a couple of different heating and air techs. I had to spend quite a bit to replace my compressor in the summer.
