After installing a second 16X20 return, relocating the thermostat to a location with a better airflow, I finally got a Tech to recognize that my system was 2 pounds shy. Now it works as I expected. On 10 minutes at 77 and off for an hour at 76. Every room in my house is 75 to 76 degrees, including the garage (See my posts back around 10/12).
Weather is cooler, but still got to 90. Will not really be sure until next summer, but looks good.
Not to criticize the guy who finally fixed it, but he comes in with "I don't believe anything you or anyone else says or measured. I have to measure it and see it for myself" A great start talking to an ex Service Manager.
After dealing with 4 different companies and several Techs, a couple of questions. Return air from a garage:
Illegal..if it has a garage door it can't be done.
OK if it has a fire damper (stupid)
If you are not using it as a garage, it is OK.
We do it all the time.
Your view please.
Is a pound of R22, 16 ounces..a pint?
Was my two pounds shy, a quart?
How can three qualified Techs miss that?
Thanks again for your posts..I really like this site.

A quart is a volume measure.
A pound is a weight measure.
They are 2 different measuring systems.
Don't confuse the two.

Regardless of what you THINK is the norm - you have a death wish putting a return or discharge into the garage. In fact in Fl. you will fail the mechanical inspection in a big way even IF you use a fire damper. Fire is actually the least of the concerns --- carbon monoxide is the culprit.

DO NOT DO THIS -

The statements I posted were the responses I got from qualified Techs when I asked them that question about returns in a garage. I do not have one.

A pound of r22 would be about 12.8 ozs of volume, depending on temp.

forgive me if I am wrong, but unless you are dealing in precious metals (troy weight), a pound is a Lb is a pound. 16 oz

You can have an oz of weight, or an oz of volume.

I believe you'll find that 128 ozs, equals one gallon.
