    Return Air Duct Size

    going back to the original question.... yes, your return grille is too small. I cant see enough of what else is going on, is it possible to use a louvered door in that closet to open up the return path?

    is sealer bad for concrete?

    Ive searched and cant find an answer....... I'm putting racedeck down on my garage floor. Seems I have some moisture migrating through the concrete (not much but some). If I put the racedeck down (free flow) it will breathe. I could seal it first, but wouldn't trapping the moisture be worse for...

    racedeck and moisture

    it just seems weird that the moisture never harmed the wood until I put the mat on top of it. this wood parquet locks together like hardwood; no gaps

    racedeck and moisture

    Got a bit of a strange problem. I have a 30 year old garage. Concrete is in good shape. In the back room of the garage (we use it as an exercise room) the previous owner put a 'parquet' wood floor down over the concrete. It is (was) in good shape with no issues. That is, until I put black...

    Mini-Split vs conventional split

    conventional system is more reliable and easier/less expensive to work on in the future when there is a problem. parts are more readily available. less efficient and bulkier though.

    duct size rough in

    what size system are you installing? also, are you running ALL hard metal duct? if you are running any flex, then those cfm numbers do not work for you. (the cfm numbers above are actually high if flex duct is used) Also, lets say you follow your plan where you put in all 8" runs....you need to...

    New attached 40x60 colonial garage

    oh, didn't realize that. I just bought a similar sandblaster and thought if I put wheels on the rear I could store it out of the way and move it when I need it since it is not a frequently used tool. when I get around to adding the wheels I'll post something up on here.

    New attached 40x60 colonial garage

    Your garage turned out great; I enjoyed reading through the progress. Quick question: I saw in one of the early pictures that you had a sandblaster. Looked like you put wheels on it? Do you have any closer pics? I just bought a sandlblaster that looks similar to yours and was thinking of putting...

    MIOSHA inspector------Really?

    while he is probably right, he still sounds like a jerk on a power trip. He didn't need to threaten tickets just yet; maybe he should have introduced himself to the new neighbors and made a couple polite suggestions. Sounds like a 'fun' neighbor; good luck. When you cut your grass, make sure to...

    40x60 Just use an HVAC/heat pump?

    On a building that size I'd forgo the mini split option. Too much equipment and unnecessary refrigerant lines, electrical, condensate lines, etc... would need to be installed. Overly complicated for what you are trying to accomplish. You mentioned in your first post you might not want to deal...

    HVAC guys - settle this argument....

    You are correct (so long as the system was designed properly to begin with). Your unit needs to move a certain amount of air. Closing vents off reduces the amount of air it can move. It will try to force air out of the other vents; but the system should have been designed to move a specified...

    ductwork size 4ton 5ton

    I mostly agree with pseudoreality and red dirt road. I do not think you necessarily need to design at a .05 for the return (if space is limited), but its good if you can and it does quiet the duct system. However, my .02 is this...if your HVAC contractor cannot run a load and custom design...

    Looking to A/C my 24'x36' steel building in FL

    I agree 2 tons should condition the space under normal conditions; however, in Florida, if the garage is used as a garage (and the roll up door is opened and closed on occasion), when that roll up door opens and the dehumidified conditioned air leaves the building and the hot humid moisture...

    Looking to A/C my 24'x36' steel building in FL

    I think 2 tons is a little light for the construction type as well as the temps you want to maintain. Also, with a roll up door you will lose your conditioned air pretty quickly; while I would not 'oversize' a house HVAC system, I would tend to oversize a garage HVAC system slightly to give you...

    Flare or Solder

    the flare fittings on the mini split are fine; of course a brazed connection is always better though. The way your ac guy really needs to do this would be to make his connections, apply a nitrogen test,check for leaks, then evacuate the system USING A MICRON GAUGE and verify it pulls down below...
