    Took a bit of doing but found a company that would do the testing for a few hundred. No company I called would do it as part of their quote for new AC systems. One said that they do it after a contract is signed and only do the Manual J that way as well, they eye ball for the estimate.

    DIY a blower door and duct testing? Thought they both require a bit of specialized equipment?

    No he's talking about improvements to problems with your home if/when any are found at testing. Are you fairly handy? in other words

    boy this just isn't my week is it?
    diy the air sealing duct sealing per findings of the blower
    door duct testing.

    while allowing the duct sealing to be done by hvac company,
    the blower door will show leakage areas in the house.
    some you address from attic..others from inside the house.
    are you willing to diy the caulking from inside the house?

    personally I find the homeowner does a better job caulking
    as they take the time time to do it well. some areas will
    require caulking twice. as the caulk dries it shrinks so
    a second application is necessary. just isn't cost
    effective to send crew to caulk the second day.

    its hard to price caulking jobs. cheap material but time
    & finesse to properly seal.
    is this something you are willing to do?
    if so, buy by the case, caulk with long life that goes on
    white and dries clear.

    hopefully you'll share your testing results with us.

    best of luck.

    I feel like you will see a lot of value in the testing, it's a pretty eye opening experience it was for me tge first time i saw it done. I'm glad you are doing your homework before you make such an investment. Lots of companies don't do man j until they get the job bc it takes time and effort and they don't want to do it then you tell all the other contractors the numbers and someone else gets the job after they have taken the time to evaluate and calculate the size

    Will leave the duct sealing to the pros, attic is a little tricky and they have insurance incase of a fall!!! Would be comfortable with the calking and probably take on that job.

    Will absolutely share results and should be interesting to see the difference in the Man J from the original quote and the one from the rater who is doing the blower/duct testing.

    Thanks for all the advice.

    blower door measures house leakage also. different steps..same equipment.

    resnet raters use duct blaster or pressure pans to test
    ductwork you would have to request if you chose to test differently.

    usually houses are pressurized to get leakage amount.
    if you pressurize you can feel the air leaking out of ductwork
    so you know exactly where to seal.

    sealing house leakage means less of the great outdoors to heat and cool
    sealing ducts means all of air you pay to condition comes into the space
    where you live. return should also be tested.

    sealing both leakage areas (house & duct) can change how many
    tons of hvac is required.
    manual J would have to reflect reduced infiltration numbers.
    best of luck.
    I have severe carpal tunnel in my hands & using a tape measuring rooms is difficult. What 50 foot laser ultrasound measuring tools do you or anyone on here recommend?

    I believe everyone ought to use the latest tools & instruments including computer software that will speedup the job of energy rating & load calcs; these days (mostly retired) it's taking me too long to do the job.

    Lot of figuring & paper work involved without good programed software.

    This one any good?
