    Thanks, Jtrammel. The sweating hasn't been happening since the tech increased the blower speed so that the supply temp is 54 (it was 49 before). Also, it had been in the 30 C range outdoors for over...

    @Jtrammel: I'd be very open to getting a whole-house dehumidifier, but my system's in a tight closet space. Do you think there could realistically be room? Also, from what I've read, a whole-house...

    @Jess: He didn't use the term "welded", that was just me awkwardly trying to describe what he'd pointed to. :)

    @Jtramme: That's frustrating beyond belief. I would have been absolutely ok with a...

    Update! First of all, I followed Teddy's advice and refrained from having the relay installed when I had the ComfortSense 7500 installed on Tuesday I was initially still thinking about trying the...

    Apologies for not writing back sooner. I greatly appreciate all the feedback you guys have given me. Called the installer at 8:30 AM yesterday and they sent a tech over within hours!

    He felt that...

    Thanks. The new unit is a 2-ton XP14 replacing an old 2-ton York. The air handler is a 2.5 ton CBX27, replacing what I believe was a 2-ton York, though it may have been 2.5 ton as well.

    Could this be caused by over-cooling, or is it humidity-related?
  8. Thanks. It's the same ductwork I've had for as...

    Thanks. It's the same ductwork I've had for as long as I've lived here (around 12-13 years) and I've never seen this happen before, so I'm confidant it hasn't got to do with air flow so much as it's...
  9. Help! Water forming on the ductwork in my vent!

    This is rather terrifying. I noticed the paint on my ceiling near a vent hatch was beginning to bubble. I opened the vent hatch and a small amount of water dripped out. Turns out that water has been...

    Oh - another question re: overcooling - how low can I bring temps without risking the coil freezing?

    Thanks for that. I'll see what I can do to get the readings.

    Re: the stat, I've been planning to upgrade my stat for some time. I've got a CBX 27 air handler, which isn't variable speed, so my Ac...
  12. Thanks, Tech23. That's reassuring. To get my...

    Thanks, Tech23. That's reassuring. To get my indoor RH below 60, I'm overcooling, unfortunately.

    If I bring my stat to 19.5, for example, the indoor RH will often climb to the late 60s, and...
  13. How much condensation or "sweating" is normal for an XP14?

    As some of you know, I've been having issues with elevated relative humidity since the installation of a new XP14 in May. I noticed today that the outdoor unit seems to be sweating more than my old...

    Thanks, Cory. I do have a cap here. Would it be safer to just run a small brush though it to dislodge the gunk instead of using bleach? I worry about putting a corrosive through the piping.
  15. Whew, good to know. Thanks. I was worried it was...

    Whew, good to know. Thanks. I was worried it was on the verge of getting a blockage. What is all that stuff?

    Could anyone let me know whether this looks normal or is reason for concern?
  17. P-Trap appears to be getting "gunky" 3.5 months after install?

    Could someone check out these images and let me know if this looks normal? This is a P-Trap on a CBX 27 that was installed in late May. I noticed it was beginning to get a bit cloudy a month or so...
  18. Shoot. It's definitely a corner placement, but I...

    Shoot. It's definitely a corner placement, but I don't think that could have been avoided. My old York was installed in that exact place, and the lines are running from there. The installer never...
  19. Thanks, guys. Pushing in against one part of the...

    Thanks, guys. Pushing in against one part of the side panel stops the sound (good call, Mr Bill), but the rhythmic pulses can be felt as I push on it. Could it just be that the side panel is slightly...
  20. Could someone give a listen to the noise on the...

    Could someone give a listen to the noise on the video and let me know your thoughts? I'm hoping the rhythmically vibrating hum isn't cause for concern, but as I just heard it making this noise today...
  21. As temps have risen, new XP14 has started making a rhythmic vibratory sound

    Is this something that happens from time to time as outdoor temps change or is it cause for investigation?

    I shot a brief video clip to illustrate the noise. Today is the first time I've heard it...

    Teddy, thanks so much for the above. That is one the most informative and amazing posts I've ever read.

    As temps have risen outside and the compressor's running longer, humidity hasn't been as...

    I know, it's really got me baffled that there can be such discrepancies from one gauge to the next. Meanwhile, when it comes to temperature, they're all reading exactly the same. In a worse case, the...

    Update: I bought an AcuRite humidity monitor (model #00309) and it's reading 4-5% lower than the Honeywell monitor. The Dehumidifier's reader is between the two.

    The more elaborate pro reader...

    Ah, that could explain things! I'm unsure of the SEER rating on the old system but it was around 20 years old, likely older.

    What do you make of the P-trap photos I posted earlier? Could that be...

    Interesting. It's odd, though, as the York system I just replaced never had a problem keeping RH below 50.
  27. Just noticed something as I was snooping around...

    Just noticed something as I was snooping around the air handler. I shone a flashlight on the P Trap, which I never really looked at for more than a moment when the system was installed last month...

    Will do.

    System is currently giving me 55% RH at a cooling temp of 18 (if I can trust both gauges here). Notably higher than my 20-year+ old system, but could this be within a normal range?
  30. Thanks, Darrell. Now that they sent over a tech,...

    Thanks, Darrell. Now that they sent over a tech, who inspected the system and gave it a clean bill of health, with a note on the paperwork showing that his humidity reader found no issues with...

    So far, there's not been much of a difference. It may just be that the system hasn't needed to do much cooling to maintain temps in the period since the tech was here, thus not giving much chance for...
  32. So, tech was here, took some readings and, oddly...

    So, tech was here, took some readings and, oddly enough, his professionally calibrated humidity reader (not sure of the technical term - an elongated, yellow piece of equipment), was reading a full...

    Will do. Technician's scheduled to come by on Wednesday. Hopefully this can be resolved with a proper change of fan speed.

    What I find odd is that the current fan speeds were determined by...
  34. I wouldn't dare try to adjust the blower speed...

    I wouldn't dare try to adjust the blower speed myself. I'd have no idea what I'd be doing It definitely wouldn't be a wise move. Now that I know this is something the installing company could fix,...
  35. Thanks, guys. I hadn't realized this was...

    Thanks, guys. I hadn't realized this was specifically the kind of issue I should be calling the installers back over. I believe they took readings before setting the fan speeds, so I'd assumed it...
  36. Lennox CBX27 dehumidification - does the relay kit make a major difference?

    Hi everyone,

    Since replacing my very old York system with a CBX27 and XP14 setup a few weeks ago, I've been seeing notably higher humidity levels (I used to have around 46% RH when my cooling was...
  37. Perfect. Thanks!

    Perfect. Thanks!
  38. Great! Is there a way to use the Prestige...

    Great! Is there a way to use the Prestige without an EIM? I'd heard not, but I can't imagine there isn't an option to hardwire it to the heat pump and air handler like a traditional stat and simply...
  39. I know I'm probably being a bit of a luddite...

    I know I'm probably being a bit of a luddite about it, but relying exclusively on wireless tech for something as critical as my heating system is something I'm really not comfortable with. I'd feel...

    Very cool. Do you know if this is the same with the Prestige units?
  41. Also, I meant to ask, could the VisionPro 800...

    Also, I meant to ask, could the VisionPro 800 perform any sort of dehumidification when paired with a Lennox CBX 27 air handler, or is that only possible with Lennox stats?
  42. Possible to use a VisionPro 8000 stat with outdoor temp sensor without the EIM?

    Looks like I'm going to go with the VisionPro 8000 over the Prestige so as to avoid being stuck with a stat that can only communicate with my equipment wirelessly, as is apparently the case with the...
  43. Thanks, guys. Relieved to know that the padding...

    Thanks, guys. Relieved to know that the padding will at least last, but now I'm freaked out about the angle of the supports. It seemed fine looking at it and the installer was confidant that it's...
  44. Installer placed rubber pads beneath XP14 to fit it onto elevated bracket

    Hi Everyone,

    Could I get some feedback on this? When my XP14 was installed last week, the installers placed what appears to be rubber padding beneath the feet so that it would be secured to the...
  45. Thanks, Doug. I'd have thought (hoped) that...

    Thanks, Doug. I'd have thought (hoped) that Lennox's own HC16 filter would be designed to work well with their modern air handlers.

    The air flow itself doesn't seem noticeably different, but it...
  46. Air handler seems slightly noisier with HC16 carbon filter?

    I've only had my CBX27 for several days now, and I'm loving it. A few hours ago, I put in a Healthy Climate 16 filter (replacing the generic Merv 10 one that came with the HC10 cabinet that was...
  47. Thanks, everyone. I think I'm going to go for a...

    Thanks, everyone. I think I'm going to go for a Prestige (though I would have preferred to avoid a RedLink setup if possible). The Pro8000 looks like a great stat as well, but I figure if I'm going...
  48. Another thing that Signature Stat had that the...

    Another thing that Signature Stat had that the Honeywell's lacking - the ability to display precise temps - for example, 20.7 as opposed to a rounded off number.
  49. What modern thermostat has the features of the old Lennox Signature Stat?

    My newly installed system came with a Honeywell FocusPro 6000 stat. For the last 12 years or so, I've controlled my system with a Lennox Signature Stat, which has been mostly terrific, but froze...
  50. Just a quick update: system is up and running and...

    Just a quick update: system is up and running and everything's working beautifully. Zero discernible movement or vibration and no rattling - in fact, this is an unbelievably quiet system. I'm very...
