    Thanks for the info. I wasn't aware of the fact that there's an official whisper volume. Looking forward to getting that decibel meter and getting some objective noise level data.

    How low of a decibel level could I expect from the best/quietest HVAC units on the residential market? Is "Whisper Quiet" (30 dB) the standard that all the major companies are trying to achieve, or are there other officially designated levels even quieter than "Whisper Quiet"?

    Thanks for the advice/input in the above notes.

    You asked whether the rep that came out was actually from Coleman or whether he was a distributor's rep. I thought he was from Coleman based upon verbal communication from the installing contractor. Looking at his business card now, I see that's he's actually an HVAC technical specialist/ technical support person for a distributor of HVAC supplies company. His business card actually has the names of four companies on it - Coleman, Daikin, Fujitsu, and Goodman. Guess I assume from your question that a distributor's rep HVAC tech specialist is not as qualified as an actual Coleman person when it comes to diagnosis and repair of this noise issue? The more I learn about this, the more I realize how easy it is for consumers without in depth HVAC knowledge to make decisions that they later regret. Wish I would have found this website and had your input before I made the purchase. On the other hand, I'm not just going to let this pass. If this unit does not live up to the way it was represented to me during the sales process, I'm going to push hard for unit removal and refund.

    I would bet you are hearing a vibration which is different from the scroll compressor which almost all units now have.

    The way the unit is piped can reduce that noise. I have an HL6B (Luxaire Badge) in my home and its great.

    Sometimes a muffler will reduce it as well if the noise is coming from the copper line.

    Okay, he was the distributor's tech rep. You want an actual factory tech rep.

    Tell that to the other people who had the "fix" installed that derated the unit, made it less efficient, and didnt heat their house as well as before.

    That didn't happen to many, but was not a great idea on Coleman's part.

    Tell that to the OP who's new 'whisper quiet' furnace sounds like a freight train.

    It doesn't sound like a freight train.

    Yeah, sure, it's all wonderful when it's installed properly


    30 decibels (db) is the official "whisper" volume. Should the OP get a decibel meter, maybe from Radio Shack, and find that it's not 30, probably more like 50-60, that's a problem. The 'official' rep can then address the 'proper install' to make sure there's 'no problem'.
    Please post a link to the article that declares 30 DB as the official "Whisper" volume for HVAC equipment.

    I found a cheap return air register making an intermittent harmonic hum more than one time.Is it possible your registers are making the noise?
    Take your time & do it right!

    Many of them ARE junk, just as some of Lennox, Rheem, and others. The difference is the huge number of models the other manufacturers offer that ARENT filled with problems and false advertising.

    Happened to 5 families in my area. the 6th just happened to arrive home to see flames shooting out of the paneled wall of their bedroom. That was just our company, there were many other reports of flames exiting the walls of the homes from the larger mobile home management companies in the area.

    but was not a great idea on Coleman's part.

    This we agree on. Very poor handling of the situation.

    It does to him otherwise he wouldn't be complaining about it.

    I wouldnt expect "whisper" from any of them honestly. Maybe 40-50 depending upon blower speed. But, check the technical ratings in your book. There should be a number given for the allowable noise of the unit. If your measured numbers dont match or come close to this number there may be a problem. Remember, tech numbers are LAB numbers... every installation is different.

    Here is the information from your HC8B heat pump marketing sheet:

    If you have a matched indoor furnace/air handler your paperwork may have something similar for the indoor blower.

    Here's the actual numbers from the heat pump http://www.upgnet.com/PdfFileRedirec...CTG-A-0410.pdf :

    Here's the testing standard noted above (link shows updated whitesheet). It shows how they arrive at their numbers:

    The link to government standards of noise I posted already.

    70db matches up to busy traffic, alarm clock, vacuum cleaner.
