I had a customer call one time and say AC is out. When I got there, they had a pocket thermometer in the supply grill. Complaint was "I have the thermostat set on fifty and its only blowing out sixty...

Movie theatre manager calls. It's Friday and a new blockbuster is in. It's 85* in auditorium "x". My dispatcher explains, "We quoted you six months ago to replace grounded compressor. We can do it...

I like to wrap valve with thin strips of dry paper towels. THEN wet with spray bottle. This causes the towel to cling to the valve. Reapply water as needed. :)

This condenser fan motor dropped in band mount. Destroyed blade, motor, capacitor, and blew fuses. Shut down entire 50 ton pkg unit. Trane

Just connect hoses to system and then unscrew hose from manifold just enough to flush out. De minimis purge.

Made in USA store! I like it.

It's not gonna hurt anything. I use my AK900 for 22, 410a, 404a, 134a, 409, 407c. I purge hoses before each use. I also keep a small amount of pressure in them while they are in storage.

I use Fluke 902 (mainly). Great meter. It could use some upgrades such as test lead storage in the back, continuous backlight function, NCV, higher ohm range, higher AC current sensivity (for...

Nice. You got any pictures?

I'd like to buy one that works with 120v to 460v hot or dead. Don't know if it exists.

What is a good breaker tracer?

Nut $10.64

This is what I've found. I will post after I get it and install.

Let the installing contractor make the call

Ha ha yea!

Do you think they nitro purged while making this monstrosity?

Yea that's how you do it.

35* suction line temp - 35*saturated suction = 5* superheat

135* liquid line temp - 103*saturated liquid = 32* subcool

Target superheat can be calculated by this...

My wife can braze better than that!

I wouldn't worry about it too much. Yes it's better to purge and pull microns down to below 500. Unless it was stated verbally or in written prior to work done, just hold them accountable to warranty.

That's how I feel about it.

Rats like ice cream too!

I have wondered this myself. I still do it. I touch the suction line, liquid line, feel across the drier(s). I touch the coils to feel temperature. I try to get a quick idea of what the system is...

410a @ 125 psi = 43 degrees F. That's not bad (given we don't know superheat or sub cool or refrigerant type). R22 @ 125 = 72 degrees F. Something is wrong there. You didn't put 410a on top of r22...

Anybody know when flow meters go on sale at Jstone? I know it's about this time of year.

Ha ha. I know what you mean. I'm a tool junkie. I have a wish list that I constantly update and give to my wife around holidays.
