    T Carlson, Based on your helpful suggestion, we've decided to remove the tongue/groove floors excepting in two small spaces for storage, where we will do our best "dense pack" beneath the ...

    I thought Title 24 2016 REQUIRED a Manual-J, and limits the oversize factor to something like 15% or something. How is it that the hack contractors are still operating on ton per/xxx rule of ...

    John: Is that another 1.5 ton Fujitsu slim-duct cassette? (I'm guessing "yes", from both the form-factor of the air handler and the use of long-throw Hart & Cooley registers.) A good example ...

    It's good to know that the cassettes will modulate with load on a multi-split whenever they can, and that the -KP09 can throttle all the way back to 1000 BTU/hr, which is GOOD. The whole ...

    Thanks again to everyone. I think my plan is going to be installing a FH-12NA in the living room, see how it does and worst case I could install a FH06 in the master bedroom, lined up and facing ...

    Darren, This article discusses stucco over furring strips: To Install Stucco Right, Include an Air Gap. Further discussion (along with evidence that paper-backed ...

    All of the polyiso manufacturers seem to have an equivalent product. Some others I've found: R-Max TSX-8500 & TSX-8510 Johns Manville CI Max Hunter xci 286 but they seem to be even ...

    Thanks Dana, very helpful. I have identified 2-3 Elite/Diamond contractors each for Fujitsu and Mitsubishi that have good social media and BBB reviews. I am working through on the Manual J, ...

    Natepa, According to the manufacturer's claims, it should work. But check with your local building inspector before you buy the materials -- just to make sure your inspector agrees.

    "They estimated that a 50% reduction in agricultural ammonia emissions worldwide could prevent more than 200,000 deaths per year across 59 countries." Death is not preventable the very best we ...

    Thanks! Some word from the Mitsubushi people today that the head itself can dial down to under 1,000 BTU, although it all depends on which compressor and what other heads are calling for. e.g. a ...

    Thanks Martin and Mike..... I will use the U-Factor alternative, looks like that gets me where I want to go, which is approximately R38 (My total roof assembly will be more like R40+).... Where ...

    Rodrob15, using the prescriptive path, you can reduce your roof insulation to R-30 over a maximum of 500 ft² or 20% of the roof area, whichever is less. (N1102.2.2: ...

    Robert, First off, I'd like to point out that your local code may vary from the 2012 IRC. Even if the 2012 IRC was adopted by your local jurisdiction, it's possible that the code was modified ...

    John, I did note when selecting the equipment that this particular unit was not rated to as low of temperatures as other units. I leaned on the direct experience of the supplier who had run his at ...

    Sensaphone offers a Sentinel system that is web based. You can connect 4-20mA transducers and pulse type inputs for the water & gas meter. Among other sensors that they offer. ...

    Doug, I didn't have fine grained enough equipment to determine the mini-split's efficiency. I did one experiment of using the mini-split for 24 hours, and then using only the cove heaters for 24 ...
  • Elden Lindamood | Apr 19,2018 11:34 AM EDT
