"I think this is one of those areas where compromise is used to have a type of "solution" and move on to bigger issues.
But back to you specific comments -
By code, flex duct alone CANNOT pass thru a fire rated barrier. If it does, that is…"

Kent Browning replied to David Byrnes's discussion When can an oversized A/C be a good thing?"This post and the link to the blog have a number of problems in addition to some valid points. I am only going to address a few of the worst IMHO -
'A properly sized air conditioner cannot "super cool" the house'. (Note the…"
Kent Browning replied to Gordon Smith's discussion Duct Cleaning? Good value or a waste of money?"There is not a "Reply" button on the last post. So I came back up to this post since it contains the statements about theory vs data not matching means keep the data and get a new theory.
Attached are two pictures showing mold growth in…"
Kent Browning replied to Gordon Smith's discussion Duct Cleaning? Good value or a waste of money?"I hate beating a dead horse but -
Quoting "...very near it the humidity is going to be close to 100%, but as the air moves away from the coil the humidity is going to drop considerably and will very quickly be above the dew point."
I would…"
Kent Browning replied to Gordon Smith's discussion Duct Cleaning? Good value or a waste of money?"I'm not even sure how to address that comment.
First - If we are talking about the "condenser" (sic) then we are talking the outdoor unit of an air conditioner or a heat pump in heating mode. Neither of which will condense water from…"
Kent Browning replied to Gordon Smith's discussion Duct Cleaning? Good value or a waste of money?"I agree the air is saturated because the temperature is at the dew point. The "amount of moisture" is irrelevant - the air is saturated. At a 55 degree dew point there is plenty of moisture to wet the inside of the ducts. Any condensation…"
Kent Browning replied to Gordon Smith's discussion Duct Cleaning? Good value or a waste of money?"There is some good info in that article but there are also errors. I give the author credit - I think he is reporting accurately on his experience. However, in most humid climates the air leaving the cooling coil is saturated and may keep the…"
Kent Browning replied to Mark Furst's discussion Bath fan weirdness"Depends on the insulation. Batt insulation I would not expect much to be drawn in. Cellulose insulation would likely restrict the leakage to where my theory does not work. Blown in fiberglass could draw in some insulation but it might be a very…"
Kent Browning replied to Mark Furst's discussion Bath fan weirdness"I am guessing based on what you posted. I suspect the fan collar to exhaust duct is leaking. If my guess is correct, the fan is acting like an "ejector pump". as the airflow passes the leaking collar it pulls in more air thru the leak.…"
Kent Browning replied to Randall Olsen's discussion How to measure room pressures"Didn't you answer your own question? "... SWS 6.6201.3a (No room will exceed +/- 3 pascals with reference to the outside with all interior doors closed and ventilation systems running) ...""
Kent Browning replied to Julie Saporito's discussion Tankless water heating and existing gas lines"First the problems - increased CO due to poor combustion, flue condensation delayed ignition, etc. Many potential safety issues.
The plumbing and mechanical code books show a method to size gas lines.The method assumes ALL combustion appliance are…"
Kent Browning commented on tedkidd's blog post The Home Comfort Book"Nate - I agree with you. If you want to "sell", talk about comfort. People will buy comfort. People are suspicious of energy savings or payback claims. But if you tell the client they are looking at a 50 to 250 year payback, most of them…"
Kent Browning commented on tedkidd's blog post The Home Comfort Book"Hmm. I asked a direct question and got a question in return.
To answer your questions -
Closing ratio is almost 100%. We don't "sell" our services. Our customers come to us when they know they have a problem and need a…"
Kent Browning commented on tedkidd's blog post The Home Comfort Book"Is there a typo in the last paragraph? Not many people will be interested in a "50 - 250 year' payback."
Kent Browning replied to Tray Biasiolli's discussion Two-stage furnace, control at furnace or thermostat?"David's comment is spot on. I would always prefer thermostat staging control over furnace staging control. (I am assuming the thermostat is making and breaking the control call for heating - not communicating the temperature back to the furnace…"
Kent Browning replied to Brandon Walton's discussion When is it too windy to use blower door?"Thanks everyone for all the info! This has been VERY helpful.
I have been reading how multi-point tests are LESS accurate than single point tests in high winds. I would not have expected that. Then it occurred to me that the single point test has no…"
