How does the air conditioner work?

[Ben J. Gromicko]

Not hard to say, "$396 for that! HA!" either.

As a result of saying easy things:
Do you hear that? ....... that's silence.... no inspection phone ringing....

Everyone who doesn't understand refrigeration should take Ben's course.

I have not forgotten how it works.

I used to work along side a refrigeration tech and I asked a lot of questions.

Surprised?

Personally... In 15 years doing both res and com inspections, I thought I knew everything that I needed. Then I produced the online training video.

I've traveled around the country teaching InterNACHI inspectors and asking this question: "Explain to me, as if I were tomorrow's client, how the air conditioner works." You'd be surprised.

I realized that the more training an InterNACHI inspector has:

• fewer mistakes are made
• inspections are quicker and more efficient
• better service is provided
• and the bar is raised for all of us at InterNACHI

As a result of taking training, an inspector can charge more money.

Training = Money.
It's a no-brainer.

I understand and agree with you.

It's just that, in my opinion, and advanced course would take into consideration that the student already knows the basics...such as, how his a/c works....and go from there.

This is not a criticism...just an observation.

Nope , I am not . I worked on it for 23 years a tech . I think may still take it but not right now, Blows the cob webs out plus CE credits.
So how many times did the tech swat you lolol

There is not such thing a cold air and HVAC equipment "sucks" not "blows".

Strike one!

Through absorption and rejection.

What's the best tool every InterNACHI inspector should use to determine if the air conditioner is operating properly in the summer time?

Maybe this picture from the class will help.

Your hand...

Around here it's mostly either a vertical sliding or a horizontal sliding window!

When I put my hand to that hole in the floor, whachu call it, a vent? It seems to be blowing, not sucking.

Question: When operating, the air conditioner's liquid line should feel _____ to the touch.
(if you know the answer, great! please let others think about it for a while.)

[Bob Elliott]

Since you wish only those not knowing the answer to respond ,the answers will be by laws of average split at 50%.

I can just hear it now:

"Please tell the court when you last had your hand calibrated."

I went to a moisture class a few years ago taught by a PHD type guy and he brought up that issue as to wheather something 'felt' damp. He said he calibrated his hand every morning when he washed them.

[Ben J. Gromicko]

I think a home inspector, guided by the SOP visual-only restrictions, will do well using a hand to feel the temperature of things - (I didn't say moisture).

And the idea (for me) is not post an answer as soon as possible, but to post questions for those readers of this thread and let them think about it. Posting answers (when you know the answer) is easy.
Posting answers (after you've figured out the answer) is the goal. (for me - being all about education and such).
