Trane xl15i compressor sound


Right now I have a lennox AC unit that is loud as heck, when it comes on you can hear its compressor and fan 3 houses down the road... I am going to be replacing this with all new trane stuff here soon, was looking at the xl15i, the first one I saw demoed had a red blanket wrapped around the compressor, and it was quiet... went to see another demo for another seller and now the xl15i was loud and you could hear the compressor very well, then noticed there was no red blanket around the compressor...

shouldn't this sound insulation on the compressor be standard with the xl15i? is there a reason why some don't have it? is there something I have to say to make sure I get it on mine? thanks!

ask your contractor to make sure you get a unit that comes equipped with the sound blanket. some do, most don't. it is sold as an accessory so it's readily available though.

I think you are making a big mistake by switching to trane from lennox.....have you seen or heard the new lennox condensers? they are some of the quietest on the market today.....take another look at lennox.

there is one main reason, our local lennox dealers are idiots... if you look up a previous post I had you'd see why I am staying away from them

if you live anywhere near field mice habitat that can be a reason to remove the blanket. Field mice LOVE to live in it and eat wires in your outdoor unit. I had 10 mice jump out at me while I was doing a maintenance on a unit. Once they are in there the blanket has holes in it and it starts to absorb moisture and stinks. I have removed them from a number of units where this was the case. It is not always the case though as many out there do not have mice in them.

Higher the seer less noise. Goodman is the worst on 13 seer even when reversing valve shifts. They had to add a recall board for 8 sec delay. Sad part is still junk.

The Smart Shift board isn't used because the old boards were bad, they are used because their design allows for a quieter defrost cycle. If the compressor shuts off and the RV doesn't shift during operation it's inherently quieter. Heat pumps from all major manufacturers have used, or still use, the old style "noisy" board.

There is nothing wrong with Goodman equipment. I install a lot of it. I have had no more problems with Goodman than with anybody else's equipment. In fact, I have replaced more Trane compressors this year than those from any other manufacturer, all but one of them under warranty.

But Trane compressors are so much easier to replace.

When there's rust on those threads you might as well reschedule the rest of your calls for the day.

As for as longevity of roto-loc versus scroll I don't believe there is any, installs being equal, but I'm certainly fond of using my brazing rig.

I thought trane had scroll compressors? I am not getting two differnt answers from the dealers about that also when I just asked... one claims they are all scroll, the other says only the older R-22 models where... *rips out hair* what does the xl15i have?

RotoLok refers to the piping connections at the compressor, not the compression mechanism itself. A RotoLok fitting functions a lot like a standard piping union. The xl15i has a scroll compressor with RotoLok fittings.

From an end user standpoint the RotoLok versus soldered joints makes no difference. When you are standing on top of a compressor inside a condensing unit, and your helper is pulling on a 24" pipe wrench with a 4 foot cheater bar on the end, trying to break the RotoLok loose, you will form your own opinions!
