Hello, I have a very loud GeoComfort/Waterfurnace
A quick overview-
Went geo, when the contractor installed it the compressor wasn't charged/had a leak. Started working and then stopped working.
He had to replace the mother board on the unit because it wouldn't kick in the auxillary heat as needed. My geo was able to maintain a 68F in a -20f week. So that was nice to know.
He also had to replace a part that was causing the unit problems every fall and spring.
The unit was installed last fall (2008).
Now the unit seems to be getting louder every day. I don't know that it should be that loud and I asked the contractor to come back over. He looked at it and said yep it's louder then most that I have heard. Oh an by the way here's a bill for me coming over to give it a yup check.
I have insulated the entire mechanical room and continue to look for sound deadening alternatives.
I need to know what an expected noise level should be for the unit.
unit details-
model p046tl111nbdssa
I am looking for what next steps should be to resolve the situation as I don't know that it should be as loud as it is. It seems like the compressor is working very hard.
I look forward to any insight that you are able to provide.
One of the forums I have looked at stated it could be an overcharged compressor- didn't know if that would be applicable in my situation.
should I plan on purchasing a new compressor and have it put in buy someone else?
Is there any hope that I might be able to resolve this with troublshooting?
Let me know what further details i can provide to better assist.
Thank you

Sounds like you have already put enough "parts" in this unit.
Maybe it's time for a second opinion.

very true....that's why I have someone new coming over. Hopefully they will be better. I am trying to get as informed as possible to make sure I can get this resolved. |

Have the shipping bolts/brackets been removed from the compressor base? |

Sounds like a lack of insulation for sound inside the housing of the unit, that is very loud vibration noise. |

Sometimes a change in polarity will cause a scroll to be noisey, have you had recent power outage?
Definately have another outfit in to check charge and rest of install.
Yes condensate drain is supposed to be trapped, the wire is simply routed poorly it was not meant to support the drain.
Good Luck,

No recent power outages. I will keep advised after the new team comes in later this week. |

How could I fix it if we did have a power outage that I was unaware of causing the change in polarity? |

Am I correct in saying that noise was not there when the unit was installed?

What they are asking you to do is switch the line voltage wires coming into the unit. There are 2 one usually Black and the other usually Red. Just switch them.
However, looking at your pictures, I see what I think is a cover surrounding the compressor. If there is one, I have not seen such a thing on a Geo-Comfort machine. The pictures of the condensare drain also concern me. I would suggest you contact Geo-Comfort and run the serial number of your machine. They should be able to tell you it's history. It almost looks to me like someone "fixed up" a used unit. This has happened before. A couple years ago, I was working on a couple Carrier/ClimateMaster units for local customer. He lost a compressor and the units were only 2 years old. He was totally dissatisfied with the installing contractor so he had me in to work on them. Anyway, when we submitted for warranty on the compressor, we were told there wasn't any, that the machines had been in a distributor wahrehouse for a while and had been sold to a "liquidator" as obsolete product. The homeower was really upset then. I've never seen anything like what you show coming factory fresh. If the unit is not factory fresh, the loud compressor could be part of the reason.
Current design from ClimateMaster has the comnpressor mounted on springs rather than the rubber feet normally used. That could be a response to a series of noisey compressors from Copeland.
One last thing yu might check is the run capacitor. If it is weak, it can cause the compressor to work harder than it should and also cause excessive amp draw. I would expect a 4 ton compressor to pull between 13 and 16 amps on 240 volts. If you have the skills and tools check the amp draw, the line voltage with teh unit running and also check the MFD strenght of the run capacitor. If all that is in order and Geo-Comfort says th unit is under warranty, complain to them and see if you cn get any satisfction. Sometimes posting your experiences on a foun such as this can get a manufacturers attention!
Let us knw wht you find.

The pictures look similar to our WF units. Is there a relationship between GeoComfort & Waterfurnace? |

Turning off the power goes without saying.
It is my understanding that the original Geo-Comfort units were WF "clones". That changed a couple years ago. Of course the original WF units were Command-Aire clones so what goes around comes around!
If the unit this customer has looks like a WF and his unit was installed "new" in 2008, that also adds to my suspecion about the history of this unit! |

It's a PO46 unit made by WF for Geo Comfort when they were a Distributor for WF.
It has single speed scroll compressor with a sound blanket using R22 refrigerant.
My concern was whether the extensive service done on this unit was diagnosed and performed properly.

I noticed with the
Condensation tube. It looks like it is being held up by a wire. That
can't be good. How should the inside tubing for that be run? straight
over with a proper drain/trap on the outside? Does it even need a trap.
It needs to be trapped on the inside but the excess tube should cut off and not wrapped around the low pressure wire. I would expect the installer to know that!
I would also expect the installer to know where the unit came from and warranty details.

I did get an email from GeoComfort and will be touching base with them in the morning. I will get a plan together with them and see how we move forward. I will keep everyone informed as I move through this process and appreciate all of the insight and help shared. You are AMAZING! |
