    Loud HMMMM in A/C

    I am hearing a loud hum or hmmm (and can put my hand on it and feel it vibrating) in my main a/c. The unit is turned off at the termostat and also the fan off. It will stay on maybe 5 minutes or so then stops. I am curious as to what this is or if it is a problem. Thanks for input. Tim

    I'm certainly not an A/C repairman (but I play one on TV). However, it sounds like an accumulator or condenser letting off pressure. I get a similar sound from my Prius after I shut it down. (How's that for comparing an Apple to an Orange?) Again, can't pinpoint the exact noise, but make sure it doesn't hamper your late Sept trip!
