    Ok thanks for the reply. I'm going to re-route the two trunks that feed each end of the house to make them straighter and less angular curves.

    Do I also need to consider wrapping the mixing boxes...
  2. Spider system - cooler air off one mixing box

    I have a couple of questions to help me wrap my head around my next steps.

    We have a large house, two zones, and apparently a spider system in the roof. There are three mixing boxes off the main...
  3. Thanks, that's good enough. :-)

    Thanks, that's good enough. :-)

    Thanks Rep. Now I know what to ask for, I'll most likely get a "manual D" done. What's the typical cost for such a test?

    Update: The senior tech came out and replaced the motor and (I think) the capacitor.

    He said he'd checked the blade and it ran true so didn't feel it needed changing (we'll see I guess). He was...
  6. Yes, very good point. I'll check with them on...

    Yes, very good point. I'll check with them on Monday. It would be good to get this unit back to 'factory' build.
  7. For the upstairs I typically used the Purple...

    For the upstairs I typically used the Purple Filtret product which apparently (from my new research) is MERV 11 and MPR 1250. I then found the filtersfast.com filters to be much cheaper so I bought a...

    It's amazing what you think you know, but really, you don't.

    I went in search of MERV 8 filters today at Home Depot, in preparation for the upcoming motor install. I'm going to put my current...

    As you say we tend to go back and forth for a few weeks prior to settling into the final season mode (especially in this crazy 30-50 degree swing weather we get nowadays (we live near DC btw). So...

    Quick update for those interested, the technician just called and they have the wrong motor for the unit so it'll be Monday before a full repair. The good news and perhaps some insight into what's...

    Yep i'll double check with them. I know they can get out and get parts while they are here, apparently where-ever they get them isn't far away.
  12. Yeah I believe he is picking up the motor for...

    Yeah I believe he is picking up the motor for this job. They were out on Tuesday but didn't have the right motor, so another more senior tech is coming today with the right motor.
  13. Ok, cool. I'll mention that to the tech too. He...

    Ok, cool. I'll mention that to the tech too. He should be here by 12 (hopefully).
  14. I usually go up there to check it out when it...

    I usually go up there to check it out when it stops working. I've not smelt any electrical smell, but then I've also never seen the motor once it was removed either.

    I'm going to ask the tech to...

    Here's some more photos.

    This is starting to make more sense.

    I also was not at all happy with the way the soft-duct work was laid out. Yes it's saggy and in a few places we've strapped it up to make it run more directly...
  17. Interesting thought. I've often wondered how much...

    Interesting thought. I've often wondered how much these high density filters would affect air-flow.
  18. Here's some photos of the unit and the data page....

    Here's some photos of the unit and the data page. Also I tried to take some photos of the cut duct work.

    I'll pop up there now and try and take some more since there should be more light now.
  19. Will post some photos, hopefully you can tell...

    Will post some photos, hopefully you can tell from one the data sheets.
  20. No icing or air issues. So that doesn't sound...

    No icing or air issues. So that doesn't sound like it's icing up. We don't have fantastic air flow to all rooms, but I put that down to crappy ductwork design and frankly I haven't metered it, so the...

    Well we do often refer to living here as "paying a toll"... But we digress.

    Not that we're aware of. How would I know if we had?

    Rep, certainly understand on builders using different contractors. I'm going to check with my neighborhood and see if anyone else is having or has had such issues.

    I've taken some photos, i'll try...

    Thanks for the responses, these help.

    I know on a couple of occasions when the motor blew, the fan wheel was not damaged in any way and was re-used, but it has been replaced by at least one tech,...
  25. Trane motor on heat pump failing every few months

    We have an ongoing situation with a Trane heat pump in our attic where every few months it keeps failing. We've lived in this house for nearly three years and in that time it's had roughly four new...
