Yes. I was building a new home in Baytown Texas (completed in 2006) and searched far and wide for thermostat controlled dampers - was told by many HVAC companies that "they" remove them weekly - this isn't true. I found one installer in Houston that would do the system the way I suggested - he listened and so did I. We compromised on 2 units with 3 ...

I wouldn't build it that way in the first place. Hiding a dryer duct within a wall and venting it through the roof (I'm guessing here, but that's what it looks like to me) is just begging for nobody to clean it until it eventually catches fire and burns the house down. I recently re-did my utility room and discovered an in-wall rigid steel duct just like ...

Another alternative is to build out one side of the wall that is away from the brace side. For example you could attach 2x2s to the edge of each stud to open up the wall cavity to another 1.5". This actually removes only a small amount of finished space in the room. If done all the way across one wall surface you would probably hardly realize that that one ...

One thing you could look into would be flat oval ducting: You can get it as small as 3" in the smaller dimension, but it will likely be a lot harder to find and a lot more expensive. Also, it will compound the issue @iLikeDirt pointed out in keeping it clean, especially if you have transitions to round pipe anywhere. I would also limit yourself to one ...

I definitely agree with iLikeDirt, but if you have no choice you can use oval duct such as this: http://www.deflecto.com/products/pc/Skinny-Duct-Aluminum-Dryer-Vent-br-4-Oval-Duct-Adjustable-27-48-4p445.htm If anything, as a safety precaution you should foil tape ALL joints and even elbows. I do this as standard even for exposed duct work. DO NOT use ...

Q1: The coil can get plugged with contaminants. Maybe if it was improperly filled, or water got in through a leak. Both situations tend to be rare. Q2: I'm sure diagnostic equipment exists, but most techs would either just flush it or pull new copper line. Some other things that tend to cause frozen coils: Restricted airflow due to a dirty or plugged ...

There are a lot of scenarios that can cause a pressure switch to report an error. As an example, one that I have seen that is actually "self-healing", I have seen really cold days where there are ice crystals in the air and as the air is pulled into the air intake it can create an 'ice dam' and thus restrict the air flow enough that the pressure switch does ...
