  1. Dehumidifier repair in Atlanta, GA area? (Thermastor Santa Fe Advance)

    I have a Santa Fe Advance with a leaking evaporator/condenser coil (it's a combined unit). The coil combination is under warranty and Thermastor would ship a replacement on request, but I can't find...

    UPDATE: I contacted a Carrier dealer, and they get this question frequently and indicated that with the Infinity you can pretty much set the thermostat as low as it will go (which is 40F) and that...

    (Oops - you'd probably have to have the condenser model to know for sure -- it's a 25HPA6)

    Not sure -- in this case it's a "communicating" condenser and I've been told the Infinity control actively manages the defrost cycle. Maybe a Carrier expert here would have the specifics?

    Ah, good point -- seems like at least a good reason not to set the indoor temp lower.

    (On the other hand though, 45-50F outdoors is wonderful for getting heat to the indoor coil, so I'd think...
  6. OK for heat pump to run non-stop for days? (colder climate)

    I have a small home recently built that is largely unoccupied during the winter, and I have the heat set on 50F when I'm not there. (Heat pump is 2-ton, 2-stage, 2-zone Infinity heating about 1350...

    Be sure to get a load calc -- that's a lot of solar exposure via those windows depending on which direction the home will face.

    Also, if the duct work is between the floors, then you're really...

    It is (R-8 flex), I just wasn't worried about heat loss/gain from reduced velocity since it's in conditioned space.

    (To Todd S -- it's not all that bad, just this one supply. It's mainly done...

    Fortunately, the ducts are basically in conditioned space, so hopefully that will eliminate heat transfer as being a significant factor.

    If the elbows stay, they'll definitely be replaced with...

    We're into the intial install phase and the system is not powered yet, but it's by far the most difficult supply register to get air to in the entire system. Even "as the crow flies", with a minimum...

    It's not so much that they are "stronger" in the center, just that the portion near the center doesn't have much bearing force to transfer to ends. If you think about it, it makes sense -- each end...

    Fortunately, there is only 1 hole in each TJI at this point, just over the minimum 5' distance from one bearing side. Where the rerouting is required would be about 3' further away.

    You're right on target.

    Anyway, the HVAC contractor has acknowledged the mistake -- it was supposed to be a straight run and this was not properly communicated to the duct crew. I'm really...

    Move duct and repair TJI's or live with it?

    This is more of a construction topic than specifically HVAC, but I thought there might be some knowledgeable folks here.

    Through miscommunication or whatever, one of my more challenging but also...

    Is it really as simple as looking at the "efficiency" of the heat pump itself? At 17F, even if the COP is still 2.5, the heat pump is putting out a good deal less heat than at 47F.

    If the output...

    The house is in Macon County, NC. I haven't seen the code, but if you have more than one floor, separate systems or zoning are required (depending on square footage and intended use). I thought this...

    Maybe it's a coincidence, but you checked the A/C mode with a 10 degree temperature differential and the heating mode with a 16 degree temperature differential. No wonder there was a difference.

    Two stage systems are very nice, but the price differential seems a little high based on some quotes I recently received on Carrier equipment (same parts source as Bryant I have been told)

    You lose most if not all of the benefit of having two separate stages otherwise. ...

    Thanks. So, I guess there that means that split between the low and high stages is at 60% of total capacity or so. (I'd seen references to it being has high as 80% with two-stage scrolls so I wasn't...
