HVAC Question about running fan continuously VS setting on Auto so it runs when AC or furnace runs

I get a lot of confusion from homeowners who are told by their HVAC contractor to run the fan "on" all the time. I realize that these high-efficiency furnaces now have the DC motors that take less…Continue

John Nicholas replied to Jerry Needham's discussion Blower door test for small apartment building"I can use my Duct Blaster on any house that I expect to be less than 1300 CFM through the fan. I will be doing a final on a 2200 sf that had an AeroSeal and AeroBarrier applied. Their ACH was 0.55 and TDL was 15 cfm @ 25. I…"

Sean Lintow Sr replied to Jerry Needham's discussion Blower door test for small apartment building"New construction - commercial? If so you can test whole building as one unless inspector for some reason says test each unit

Jerry Needham replied to Jerry Needham's discussion Blower door test for small apartment building"Thanks David. I have participated in the adiabatic leakage testing on a 16 unit building and it seem to work good. Had hoped to not get that involved in this small project but may not have a choice. Keeping my fingers crossed that…"
David Butler replied to Jerry Needham's discussion Blower door test for small apartment building"It depends on purpose of test. If it's not for program or code compliance, then testing the building as one unit makes sense. It eliminates the pesky adiabatic leakage that would occur if you tested each unit individually. If you're…"
Jerry Needham posted a discussionBlower door test for small apartment building
Today I received a request to test 4 units for a small apartment building. He says the building is 32x52 which is 1560 SF. There is 4 apartments which are 1 bedroom and living room plus bath and small kitchen. If I test each unit, I suspect they are approx 400 SF. These units will have to be very tight. He wants me to open all the doors and test from one end of the hall. I have never done this is 10 years so not sure this is kosher.Any thoughts.ThanksJerrySee More

John Nicholas replied to Jerry Needham's discussion Condensation on ceiling and walls of master bedroom"Jerry,
;Have you opened the cathedral ceiling? "
John White replied to Jerry Needham's discussion Condensation on ceiling and walls of master bedroom"Condensation on ceiling occurs when the attic space above is poorly ventilated or insulated. The traps heat in the attic, which then warns the ceiling. When the cool air from your living space rises due to humidity in your home then it comes in…"
John White replied to Jerry Needham's discussion HVAC Question about running fan continuously VS setting on Auto so it runs when AC or furnace runs"The fan only works when the furnace tells it to run. The fan is controlled by a timer circuit or at a boundary circuit on the device. The fan starts to run for approx. 40 seconds after the burners are switched on and off for approx. one minute after…"

Spray foam on attic deck to stop mold
Posted on April 7, 2018 at 8:57pm 2 Comments 0 Likes
I am working with an insulation company who has already applied 2" of closed cell foam over the deck of a roof deck that has been remediated for mold twice. It was thought by spraying the foam, there would be no chance of the mold coming back. This is a million dollar home in the Chicagoland area and homeowner is trying to sell the home but a private home inspector says the foam will shorten the life of the roof and he has scared off perspective buyers with his talk. I have told the…
