    I will corroborate the improvements, but my CFM 50 rate was already down to 2078CFM due to other work I had done and then dropped down to 1955 CFM now after the Aeroseal process. Biggest improvement...

    Unfortunately due to the one week delay in the final test out, the bump out and fireplace spray foam occured inbetween the baseline and final test of the duct sealing, so it is impossible to isolate...

    Yes, as the temperature equality now between floors is the most dramatic effect. Basement is much closer to first floor temp and I only have a 0 to 1 degree difference now between 1st and 2nd floors....

    Shophound, I wouldn't mind doing this, but conditions have changed so much, there is no way to compare directly to original data. Here is a list of changed variables:

    1. Ductwork now sealed
    2. ...
  5. As far as retesting the return balance issue, I...

    As far as retesting the return balance issue, I don't think it will be worth it, as too many other variables are changing. I got a local spray foam company to give me a very good price to foam my...

    I am literally only 3 days post sealing right now, with very little time really spent back in the house to quantify real results. I can say the following with certainty, but need to measure to...

    Long term, there is no doubt in the cost effectiveness, but short term I was assuming a conservative 6 year payback, since my house is pretty effiecient already. I figured a 15% reduction in A/C and...

    I figured that by your user name, I just wanted to get that info out there. I am as excited as anyone to actually quantify the actual best estimate of Aeroseal impact through my TED meter...

    Obviously that question was for TED, but don't think that just because some of the leakage is into the envelope that you don't gain efficiencies from reducing that leakage as well. My basement, and...

    Here is my Aeroseal results:

    Return Leakage = 350 CFM. Reduced to 92 CFM (Wall Cavity)
    Supply Leakage = 250 CFM. Reduced to 60 CFM.

    Unfortunately my TED meter is only reading from 1 phase of...

    True, that always cracks me up. I have seen guys wearing short sleeves when the temperature hits 45 after a bit of real cold weather.

    The trees were there all along as the house is built in a protected wetlands area and they were only allowed to clear 12' around the house.

    I am 90% sure this is just a normal propane furnace and...

    Dual Fuel Setpoints?

    I convinced a freind of mine to go to dual fuel system last year with a 14 seer heat pump main unit and switching over the propane furnace to backup mode. We live in MD so, he had the HVAC...

    Blower door test yesterday showed the baseline leakage at 50 kPa is now down slightly to 2078 cfm from 2300cfm a few years ago due to me sealing up a few of the problem areas. I am hoping the...

    To be honest with you guys, I think you nailed it. I will review the summaries again when I get a free moment (work has been nuts) and highlight or add to the points. I actually just got on as I...

    Good summaries guys. My savings is still continuing. I have been on vacation so I have some really low days, but most days in the high
    40kWh to low 50 KWh range.

    You kind of lost me there Brian. The upper floor walls are simply built laying flat first ant then lifted into place and nailed into the OSB flooring. The bottom 2x4 simply sits on top of the OSB...

    Yes, 2300 sq ft. without the basement area counted in and all three levels are the same size, so I guess around 3450 total. Now I am not sure what the 2300 CFM means. The .43 ACH is what I believe...

    There are not any easy ways to balance the supply system further that I can see. I was thinking that sealing the ductwork will hopefully give me a minimum 200 CFM extra as well a eliminating a large...
