    Would you mind describing the various things you use your tablet for? Believe me, I have a very long list of things I want my techs to use them for, but I'd like to hear what they *are* being used...

    Interesting. I've actually wondered why someone didn't something kind of like this - or maybe I've just not been able to find it. I originally tried looking for a wireless transmitter and receiver...

    Actually,without looking at the price (bad idea, I know), that looks like it might be just what I was asking for, and then some. I'll have to study the specs and directions to make sure, but it could...

    I bought the big Kindle at the end of last year to test it.

    It's very easy to add PDFs. You plug it in to a USB port and it shows up in file manager like another drive. Just drag the files.

    Not enough heat. Did you downsize the furnace? I've seen moisture run down the flue and fry a circuit board.

    There are elegant ways to correct the problem that have other benefits as well. Circulating air in the home works brilliantly even if you *don't* lower radon levels. Radon isn't the real culprit....

    I used to be in the radon business, but I got out. I could write a book on why, but the bottom line is that I didn't believe I was providing any value to my customers. I had a run-in with EPA at a...

    In my neck of the woods adding electric heat strips and shutting down the gas would just about triple the cost per btu delivered. Is it really cheaper where you are? Here even propane is just about...

    N2 flowing is absolutely a must for 410A systems. 410A, like R-12, has solvent characteristics that R-22 didn't (doesn't) have. A 410A system will polish all that stuff off the copper sometime in the...

    I hope you're at sea level (or lower). We struggle at 4,500 feet, I typically oversize my blower by one size for insurance that I have enough cfm.

    Make sure the contractor takes your ducting into account. Very few mobile homes do an adequate job of moving more than about 1200 CFM of air, and you can't skimp on air with a heat pump. You may need...

    You will find this situation to be the norm. Typically ducting is almost big enough to deliver the heat load, and it's nearly always too small to properly deliver the cooling load. So most of the...
