    New RUUD system -very noisy heat mode

    Have a new RUUD 3 ton heat pump (UPRL-036JEC - Model Number & RHPL-HM3621 Air Handler). This summer it was extremely quiet to run, but since we have turned it to heat it is very loud with noisy vibration inside the house. You can hear it all over the house. The outside unit still runs relatively quiet not as quiet as cool cycle, but still quiet enough.

    What is the big difference in the 2 cycles and what can we do to eliminate this noise on the inside of our house?

    We have been very satisified with this new communicating system so far except this noise problem.

    The noise stops and it goes back to normal.

    Not an unusual problem with a scroll compressor. In heat mode it sets a vibration into the lineset. Tech will have to see about isolating the lineset from the structure. OR! We had one which was a 13 SEER that did this. Changing the outdoor expansion valve solved the problem. My system, which was a 1994 vintage Rheem pump. The indoor coil was vibrating. I put it up on 3x3 cork pads and quiet. So it should be solvable, might take some detective work.

    Do you mean putting the indoor unit on cork pads OR the coils on the inside of the indoor unit?

    Noise issues. Hate em.

    I would suggest calling the manufacturer's tech support if you've checked and confirmed all you can think to. That is, if you haven't already

    Low air flow through the air handler will cause high head pressures in heat mode and make the compressor noisy but only causes low coil temp in cooling mode. I have seen this several times and correcting the air flow solves the problem. If that is the problem.

    Just like stated earlier. Call the installer first.
    Every problem gives us the opportunity to choose from several solutions: stupidity, ignorance, indifference, or brilliance. Which one will you choose?

    Check your filter first. If that's not the issue then use that warranty you paid for.

    In my case putting the A coil under the furnace on cork pads did it. Coil was sitting on a wooden deck.

    This sounds more like the R410a 13 SEER Rheem pump we fought a year ago where changing the outdoor TXV solved the vibration.

    Often the charge must be adjusted (some removed) in the heat mode of rheem /ruud heat pumps. Specifically, EVERY 3 ton rheem I've installed necessitated some charge removal in the heating mode.

    They should return and compare the heating pressures to the chart on the door of your heat pump. The rheem heat pumps become very noisy when running at elevated head pressures when in the heat mode.

    Thanks for the good input. As previous post suggested, I am calling my installer, but want suggestions from experts that have had the same problem and many of you are RUUD/RHEEM specialists.

    Well, I called my installed 2 times this week about this noise problem, but he has never returned my call. I went down to the basement this morning while the heat was running and BaldLoonie is correct the lineset has a vibration in it. I could hold the lineset and put some mild pressure on it and the vibraton stopped. It is still noisy with a loud hum, but it stopped most of the vibration. The outside unit is right in front of my kitchen window and the line comes into the basement under the kitchen floor. Thankfully we have not had to use our heat much this fall yet, but it is making us crazy and we really want it fixed before cold weather.
