I've had to use it before at another company. I have used it with limited success when the leak was very minor, however plan on returning to recheck the system about a month later. If the system...

Thank you for the encouragement. I have only owned a buisness for 2 1/2 years, I try to be VERY thorough when it comes to bidding on commercial jobs. I always run the load calcs despite what is...

Sorry for the typing errors, I'm posting from my phone...

Architects are the worst!! I am having an issue with an architect right now due to a poor design on his part. I found the flaw when I bid the job, advised him of the problem and his response was...

At 40psig, with r22, gives a 17°f sat. temperature. You say you have 2.8°f sh, thats a 19°f suction line temp. You are not boiling off the refrigerant in the evap coil, but definately in the...

With the current price of R-22, there has been a influx of MO-99 and R-422b in my market. I have heard some good and bad things about both of them. Its anyone using these products and if so what are...

didnt mean air, but gas in general. in a vacuum electrical resistance between an open span decreases Incredibly.For example At a 120 psig with R-22 gas, span resistance would be something like 550...

John, I look up to you. I will try to have the same attitude that you have, you seem to be very thoughtful of others and I hope that you show me the mercy as you have pony when I stumble in the...

Agreed. BUT, look at his previous threads? That CANT be a PRO! You, timebuilder, and other pros, SURE but this!?

Or "That broken garden rake was my Great Great Grandfathers from Ireland!" Swear to God that happened to me about two years ago. Other than blazing saddles, he was the first black irishman named...

Just looked at his threads that he started, very interesting...

I hate to be ugly to the guy if he needs help, HOWEVER what I said about protecting the trade is very important to me. As KB COOL said about paying his dues, that is where you get your tech skills...

air itself is an insulator, in a vacuum the lack of air GREATLY decreases the electrical resistance between the windings making it more likely to arc out.

That is EXACTLY what I was trying to say, sorry tech it out. long day...:cheers:

section 406 in the ICC is all bout testing and purging gas piping, types of testing gasses, pressures, time tables, etc..

According to the ICC 406.4.1 "the test pressure to be used shall not be less than 1 1/2 time the proposed maximum working pressure, but not less than 3 psig." and continues later on to say that less...

I understand that and I DO kinda feel like an a** for being so critical, BUT it seems like he has his own repair business and has NO idea of what hes doing...

HELL, I think the first edition would be helpful in this situation!:bump:

I understand what you are saying, my comment was stating that if the control circuit is not energizing the relay it WILL read open, you need the power on for the control voltage to check if the relay...

to AC5096: thats the best thing for this situation!

how long will it be before we see chris mathews interviewing pony on a hidden camera show? Customer in the background saying "I paid him all this money and he put in a USED unit!?!?" There is a...

What it comes down to is WE HVAC/R techs have a reputation to protect. It has been slandered and twisted by some "techs" to the point of public distrust for our entire industry. Those that represent...

yup. thats the only way to check the control circuit

actually there is a ceramic post that sits on top of the bi-metal disc, when the disc is heated it "clicks" changing shape from converse to convex pushing the ceramic post up and closing the circuit....
