Amen !

Texas don't worry so much about what others do. Look after yourself.

I don't know where you get that I'm arrogant, just read your posts and others that responded to them. You seem to be a little defensive about others that have a different opinion than you. You will always find others that are more experienced then you that try to help. I've been in the hvac trade here in Texas for almost 20 years and simply stated that here we deal with extreeme temps and humidity, and you see a lot of equip failures due to improper maint. and service. Not saying you northerners don't have your own issues, being from Michigan I know what its like there. When it's 102 with 90% humidity, everything matters.

I'm sorry for insinuating you may be lacking in any ability, but I read all of the comments you had made about others have said and you seem to be the arrogant one.

I'm finished

LOL... His post is a demonstration out how over zealous ground standing can cause zealous responses from others.

good point

Just remember, that if that belief is wrong. The ground you were standing on, was the line for humble pie.

I have thought I was doing good and now I got to retrain. I am actually booking in a few coarses soon. I am not scared to learn. Can you do me a favour and translate what the post before you is saying. I have to spend more time in your country. Is he calling me a dumb ass or trying to set me up with his mother.

My apologies.

You're an idiot.





Sorry. Couldn't resist.

Glad you were able to learn something.

I am using superheat now

I'll take hot summers and mild winters, you guys can keep the cold.

If I was ever exposed to -40º, I think my thick Texas blood would freeze instantly, and I would fall over dead.

I do see a lot of things done here with the installation and repairs made on gas furnaces that often make me think that it is a good thing that furnace is being used in an area with mild temps, cuz someone would die if it had to run for long at a time...

What the hell does posting pics have to do with being a hack anyway? Maybe if you were applying you skills down here in south texas where we actually have some heat and humidity you'd have a better understanding of the various conditions that affect the refrigeration system.

What is it with you people from texas

The reason I had a response like the one you see is I hate ignoran people.

It's only fixed between 8 and 12 if it's working correctly. When charging, you should be looking at both sides of the refrigerant circuit.

Step 1 - Verify airflow using the appropriate instrument.

Step 2 - Obtain Evap EWB, EDB, LWB, LDB

Step 3 - Obtain superheat and subcooling readings

Step 4 - Adjust charge as necessary.

As far as 20* that is only on real hot days where you can achieve 20 * delta t

It's 69°F right now. There's a 22°F DB dT across my indoor coil. I assure you the charge is dead nuts.

DB dT will lie to you if that's what you're using as a test without measuring WB.


Skipping any of those steps makes any adjustment of charge a guess.

[QUOTE=mark beiser;1858928]So you don't take important diagnostic readings because you are in to much of a hurry?
You try to achieve a 20º td through the indoor coil based on what?
Do you actually take the airflow readings, return air DB and WB readings, and do the calculations to determine that the 20º td is appropriate? Or is it just a number you picked for all conditions?

Read Mark's post...


You'll see why you are a hack.
