Hey I am service tech, and a dang good one at that, our job is to talk about the equipment, not necessary the folks that design it, unless they start calling us names.

What is the definition of an engineer? Answer: Someone who solves a problem you didn't know you had, in a way you don't understand.

Western WA spans several 1,000's square miles so NO one knows your location.
It's all about LOCATION- LOCATION - LOCATION.
Generally, one would use a heat pump in WA.
I would say heat strips are sufficient given that the heat pump is sized for Head Load in the NW.
+ electric rates are generally Extremely Low in WA.
Send building plans and location and I'll tell you what size heat pump and strips you need.
U-value of windows MUST be determined.
Perform a Blower Door test to determine infiltration
which may be >> 20% of the Heat Load if care was not taken to make it tight.Designer Dan

If you have any illusions of me hiring you, think again.
Hello Dan, apparently we can't have a civilized discussion here, so I tried to PM you but can't find any mechanism. I run Linux so don't have Skype set up. I'd put my company website here, but these people are just so nasty here and after 30 minutes I can't edit posts. The mods knock out earnest contributions and questions in others' threads in a second, but where are they when this sh*t goes on? Do they like this in their forum?
Agree, and I expect to run the HP at least 80% of the time. I question whether it's worth the XC95m, but there don't seem to be any decent alternatives. I would like to have the flexibility of using gas, even though our electricity here is socialized and so is about the cheapest in the nation, not to mention being mostly hydro and green as can be.
Then there are my other questions.

12-09-2012, 02:26 AM #25ths.gardenweb.com/forums/load/hvac/msg0422373318975.htmlComfort R is a Trane feature on var speed blowers that supposedly gives more humidity control during the cooling mode. If set up correctly,during AC cooling, air moves over the coil more slowly at start-up resulting in increased moisture removal. I personally think this is more hype and a sales tool than anything else and of course other brands such as the Carrier Infinity/Bryant Evolution systems have something similar, even better.
As stated, it has to be set up correctly and I have found that some Trane installers are deficient in this area. The settings are made to "on/off dip switches" that are inside the control cabinet for either a var speed furnace or air handler. Really I think the settings are self explanatory if one is literate, has basic HVAC knowledge, and knows his equipment. Instructions are inside the control panel door. I suggest you go over this at the airhandler with the installer before he leaves the job to verify the settings are correct. Since this is a new install, it is not up to you to make the settings.

Charges contaminants so they are attracted
to oppositely charged collection cells.
Couldn't find specific programming documentation on the STAT
If you oversize a coil, you have to provide the correct size metering device.
Normally the chosen seer already gives you increased coil surface area to achieve itEconomy - Quality - Speed <---- pick two

Have you contacted WHAC Corporation.
