    Insulating a already plywood covered joist

    There is an amazing difference between no insulation and 4". If you will be heating 24/7 then it is economically very poor to slack on the amount of insulation, but still way better than nothing, -- at least you could actually warm the place up. 4" is very small number of inches compared to the...

    Mini split communication cable

    I thought I would ask a couple of minisplit brands about this and I got 3 14ga conductors and a ground, - - no other specifications to narrow things down a bit. I expect their liability is covered by specifying to be installed by certified licensed people of the trade. Did not mention stranded...

    Mini split communication cable

    Some very practical do's and don'ts here. It would be interesting to know what has been going on in the inspection world with these cables. The way they are being used and run seems to put them in a world of their own. I didn't think much about it when running what the Mini provided but when...

    Mini split communication cable

    when hooking up minisplit condenser to inside evaporator, if you go over 35 feet you have to supply your own wiring. The wire needs to be 14ga stranded four conductor, color coded. What should be the way to accomplish this safely (to code if you will)? SOOW looks to be the type of cable I...

    Peg board choices

    OOPs I was just assuming peg board hooks are peg board hooks. So just going to the store and getting some hooks might result in stuff that fits 3/8” board. And I suppose now that the metal board hooks would be different also. I will investigate hook supply before getting the board. Thanks

    Peg board choices

    Thanks all. I intuitively felt the situation is as described. But it is sure easier to pursue something when you are confident of the lay of the land. Didn't see anything on their websites. BTY is that stuff MDF or is there anything other I need to be specific about other than 1/4" thick

    Peg board choices

    50 years ago I did my first and only peg board project. Bought some 4'x8' sheets of (I am guessing MDF ). It was hard, durable and took a beating loaded with all kinds of hooks and worked well for the 30 years I lived there. Its time for peg board in my new garage and when I go to Home Depot...

    Sharbites for Hvac

    I have done several ac rebuilds on cars over the years. Several brands use o rings on a flanged tube slipped into a larger tube with clips to keep them from separating. They work fine. On the autos I have diagnosed, the leaks are the compressor seal, rubber hoses primarily at the swedge or one...

    Anyone Here Doing Their Own Auto AC Work???

    I have done an old Mercedes 240D compressor seal replacement, 1985 BMW 318I freon 12 to 134A conversion, 1994 Dodge Cummins truck complete rebuild after evaporator went bad in dash and eventually ruined the compressor, Also 1996 Ford Mercury Marquis, compressor change. Did the Mercedes with out...

    Under sizing heat pump

    JBudd2 I never even heard of minisplit in 2012 wow. They have been out there all this time. I think it was on GJ 3 years ago that I became aware of them and went with them on my house. Anyway I am finally pulling the trigger on a Cassette !8K Hyperheat Mr Cool. I will be lucky to get it...

    Under sizing heat pump

    Update: talked to service techs who seemed baffled by my question but one of them did some research and got back to me. His answer, (sells Mr Cool,) from Pioneer was it helps, that is the cooler the room the easier the compressor is working all other things being equal, in a heating situation. I...

    Metal roofing for ceilings???

    I think I am getting less noise than with drywall. Someone suggested that the ridges on the metal breaks the sound up. Anyway my concern about sound vanished There is nothing goi g on with the sound that I can notice and my ears are very sensitive to reflected sound.

    Under sizing heat pump

    Thanks, I was pretty sure that was the case but just wondered if perhaps pressures went out of range such that some overstress might be induced if say for instance you ran one of things in a cold warehouse scenario. For the limited times when it would not keep up I would just pay the bill as...

    Freezer in an insulated but not heated Garage

    I ordered a GE garage ready chest freezer, hopefully to make quick work for this concern. It could just be marketing gimmick of some sort that catches a lot of sales for them and in fact very little meaningful difference in the actual freezer. I do know chest freezers do not have the problem...

    Under sizing heat pump

    Basically you have answered my question. Figuring out what those specs mean is a bit daunting since they play so many games with what they call things. I will be doing the research. I understand COP vs efficiency, performance curves etc, although there is a dizzying array of formats for...

    Under sizing heat pump

    If I can find a unit that is designed to operate similar to the some Mitsubishi models that have some sort of bypass mode for the thermostat which goes down to 61 degrees or so I would look at that. Price of a Mitsubishi is not in the budget. But the main point of my original post is a bit...

    Under sizing heat pump

    Freeze protection sounds like the apt description for what I want. I hve seen that feature featured. Is that feature something buried in the specs or do I just need to start googling.

    Under sizing heat pump

    I heat my garage to avoid freezing and to take chill off when I work out there. Low 40’s to mid fifties is just fine most days. Most mini splits systems cannot be set lower than low sixties. Am I right? I want to put a 1800btu minisplit in my 24x36 stick build that is well sealed and insulated...

    Polyspartic floor smell: 3rd time doing this and I'm nervous

    Just asking but wouldn't the cure be affected by the actual concrete floor temperature. Even on a day with in the recommended temp range a cold floor would cause you to need a warmer day for cure etc?

    Metal roofing for ceilings???

    I used white liner metal like in some of the pictures above. Seems like everyone who walks into my garage notices it and make approving comments. I don’t know if that happens because it’s not something they have seen before or what. Blown cellulose in attic. I am very pleased with the whole outcome.
