We have a three-year-old air conditioner that all of a sudden is making noises...like fast heartbeats...bump, bump, bump, bump and it won't stop. What can I do to stop this? Does it need to be serviced...would that stop it?...or is it time to get a new one?

Thanks!

Mark, is this a window A/C or central unit?

We had a window unit in a former home that was doing something similar, and it ended up being because the case on the exterior had gotten dented to the point that the case was pressing against the "guts", and the vibrations from the machinery were being transmitted to the entire housing. Once we pulled the dented area back to its original position, the noise disappeared.
