And what did we buy today?

There are date calculators that make it easy, I don't actually keep track. I quit on my 50th birthday so that part is easy.

Ahhh.....good for you !

Of our three kids two smoke cigarettes and they seem to think they’re immune to the related disease.

I’ve had three friends that were told by doctors it would kill them if they kept smoking (copd, emphysema etc.) two are dead.....the other is still smoking while on oxygen!

It killed both my mom and dad, one at 57 and the other at 61, two uncles, multitudes of known associates.....I don’t get the draw at all. 😕
 
Put a down payment on central AC yesterday. Funny process, I got 3 quotes, each 1 a different size! 1 did it by square footage + window size & direction = 3 tons, another by square footage = 3.5 tons, another by square footage + furnace ducts = 4 tons. I went with the 3.5 as it was low bid and quicker install, and the 4 ton bidder offered to price match, meaning they were OK with 3.5 ton.
 
...central AC... 3 tons... 3.5 tons... 4 tons. ...Location: Calgary, Alberta

How big is this house??

(And do you really use Tons in metric Canada? Ah, you share the retarded US market....)

South of your latitude, I cool a good size house with 1.5 Tons (27kBTU/h in different old units). I arrived at this (also 32kBTU/h heat) myself after careful figuring and observation. After 4 years of living with my guesses, I'm pleased.

I could have gone 48kBTU/h heat: modern low-mass furnaces have small shut-down loss and over-sizing does not increase running cost (and first-cost difference <$100). Get a little quicker pick-up after the overnight set-back. However bigger heat means bigger ducts to avoid noise and over-heating the fire-pot (what killed my old furnace).

But "air conditioning", at least in the East, is a lot about humidity. And at the conventional surface temperatures, an oversize A/C will bring the temp down much faster than the humidity. It won't get dry (un-damp).

By closely figuring my cooling, the A/C runs pretty steady. On "those" days we turn-on after lunch and let it run past bedtime. The temp comes down in an hour but it takes near 4 hours for the humidity to fall much. Afternoon to evening it runs straight. Overall about 11 of 14 hours. Does take the edge off the damp, can even seem "dry". With the condensate pump chugging-out a quart of water regularly.

-*-*-*- Ah, I may be misunderstanding your climate. Mostly not hot but a few days get HOT. Humidity is what I would call low! <50%RH in summer. Dryer than Los Angeles, wetter than Los Vegas. (In much of the east, evening RH is 90%. :scared: )

I've had the 2nd edition for 23 years. 'bout wore it out. Some of those tables I've probably thumbed a thousand times. Pipe-size pages coming out.

The 4th is mildly fatter, but I instantly noted 5 or 6 sections not in the 2nd. Joist tables. Knot drawings. Table of power plug shapes and ratings. Much expanded data on air tool consumption. And significantly improved layout of sheet metal gauges. Steel plate weight now given in both pounds and kG. As ever, Conversion Table for units you never-ever want to find (and it has come in handy reading old property deeds).

Since this is a Global forum, I should note that only some of this will be useful if you don't work in the NAFTA marketplace (whatever we will call it next year).
 
PRR, yes it is dry here, and yes the hottest days of the year are pretty hot.

The house is 2300 sq ft, but has a open landing, and would probably be about 2500 sq ft if the ceiling was continuous. Built in 2000 so insulated.

1.5 tons sounds really small for up here. I think even townhomes here typically get 2.5 ton units.

I think 4 tons is the "safe" number for my house, and that quote was by a reputable vendor that is my go to company for service. Their bid was high though; I started to go down the road of them price matching the 3.5 ton bid, but their install date was ridiculous, so I went with the low bidder. I didn't get the base compressor though, I picked the one that was 1 step higher.
 
PRR - if one was disposed to pedantry, there’s about two hundred pounds difference between a British long ton (20 hundredweight) and metric tonne (2000 kg), and many of us Canuckistanians have no problem switching between imperial and metric, depending on the context. For example, while I find metric the default to work with when building, and our petrol is priced per litre*, I still want to translate liters per 100km to miles per gallon. Yes, I know there are online calculators for that conversion.

Of course even the latter is confounded by the difference between US and imperial gallons, and now that the kilogram with which we grew up has been redefined, I’m about ready to throw up my hands.

*gas prices fluctuate here like crazy, as of this writing are running at $1.559/litre - and why the fudge the .9 cents? - which translates to $7.08 Cdn pesos an imperial gallon.

Yeahbut... in *refrigeration* "ton cooling" has specific historical meaning, 2000 pounds of ice per day. Since ice-making was the first major use of mechanical refrigeration. (And the death of a thriving ice-harvest in Maine.)

I made a boo-boo above. 1.5 tons is 18,000BTU/h. (And yes, in Texas they grow window A/Cs that big.)
 
Got a Tektronix 130 capacitance meter and the calibration jig that goes with it. This meter measures 300 pF and down, plus low values of inductance. Got it on Ebay from a seller who doesn't want to ship to Canada, but he nicely accepted to do it for me.

w140.com has this on it ---> 130 - TekWiki

Sweet! Always does me good to see those lil' Hammonds going to a good home and not sitting out on the curb.

Does the vibrato have a reiterating, 'uh-uh-uh' sound instead of the smooth wavering effect?

Oddly, the vibrato sounded like it went into cutoff the first day I fired the organ up and then settled into what I would expect for that organ a day later. It is not the Leslie sound for sure, but not so bad.

Also I told the kids "This is your toy to play with" Youngest is 12 and the oldest is 18.
