Hi there! I have a 2018 Honda accord sport. I recently have the a/c evaporator coil replaced. Ever since it was replaced I have a humming noise when I accelerate and when I let it go its goes away. It doe that every time I shut the car off and start it up after a few seconds it makes a humming noise. The mechanic that worked on it cant figure it out. I'd like to know if anyone knows what this is or have gone through this? I never had this issue before.
