    I read all the posts. What do you think I meant by "make the connections"? Do you seriously think that I was was assuming all he wanted a pro for is to connect tubing? I don't really know how to take...

    Timebuilder, he had already addressed post 39 with post 23.

    He said "ditching the external disconnect was decided by the municipality" and "The installation of a lockable breaker was the solution"...

    All I can say is that "not knowing what I don't know" has been both my friend and my enemy. Either way I have benefitted in the long run from the experience.

    I do appreciate everyone's concern.

    I don't know about that. I can write a decent contract specifying responsibility. I've consulted and contracted my labor before.

    I think the OP is accepting responsibility for the project. I think he just wants to hire someone he trusts as a sub to make the connections, and as a consultant to verify the engineering. and so far...

    Got it, 0.225"wc TESP. That's reasonable. The support tech prolly has no data on fan/coil or AHU coil pressure drops. Was everything else in range? Is anything influencing your suspicion of low air...

    Hardest part is running all those line sets. I wouldn't to do it by myself but with/or as a helper, it sounds like a good reason to visit Jersey. Besides I actually like an install once in a while.

    From your original post, you are actually measuring pressure drop and not TESP. I don't think any manufacturer publishes PD for fan/coil units, only TESP.

    You need to be on the positive side of...

    That is one fantastically informative document! My gratitude goes out to rundawg for putting that together. The graphics make this the most understandable TESP literature I've ever seen.

    I love it when we experiment on our own systems, good or bad we always end up learning something.

    Chances are that a 2-3 ton TXV is too big for a 2.5 HP outdoor unit. But maybe not too big. If it...

    Jim, your onboard barometric sensor is your best bet over gps, as altitude conversion is just an estimate. Also the barometer that the weather stations report are calculated to represent sea level so...

    You heard wrong, the particles aren't small like asbestos. Our lungs will deal with it like any other dust particles.

    I wouldn't worry about any coming off unless you disturb it. The fact that...

    Sounds to me like what we call "oil canning". Remember those old oil cans you would squeeze to get the oil out? Well no matter... Usually it happens when the blower turns on and (de)pressurizes...

    I've used tif's ZX-1 for many years. When the sensor is new it will easily pick up the leak from the H10's reference bottle. Aside from the false positives from disturbing the airflow or banging the...

    Indoor conditions? dry bulb, wet bulb?
    Outdoor dry bulb? metering device?

    I'm guessing 80*OD, 78*ID/67 wet bulb with a TXV?

    IF so, then "TXV underfeeding or other restriction downstream of the...

    Indeed, dedicated return or transfer ducts/grilles will make a difference. You can't put more air into a room than you can let out. Some is coming out from under the door but some is also being...
