I just wish I could find a chart to be sure, a few feet on this run makes a difference.

I am looking for how you add the fitting to figure the length of your run.

I have looked high and low for this information. What is the correct method for figuring EL for black iron fittings on an LP gas line. It is not in the Mass. Code book that I can see. I get answers...

I have found that it can be a pain to lug my manifold gauges and temp probe every time I step out of the truck. Now in my toolbox I carry one gauge on one hose and use a pocket infrared thermometer...

I do residential heat, ac and small commercial systems.
Once in a while I get a call to help out a friend with their home refrigerator. It is usually an electrical problem that can be found easy...

thanks

So what would I be looking for Model # on the compressor?

What information do I need to swap out a compressor on a refrigeration unit? I have an older reach in cooler designed for R-12. I realize I need to convert the refrigerant also.
What I am asking is...

If you do work in refrigeration that involves food products, do you need insurance in addition to your general liability insurance to cover loss of food products if you are blamed for a system...

Yup, if it was such a good idea I guess eveyone would have one. Thanks for the response, where would one find info on the heat reclaim system.

I did a search and did not find anything on this subject so I want to ask. I have a customer who has walk in coolers for his beer products; he also lives in an area that pays one of the highest...

To garnerac, please explain are you a seller of this type of product, I am always interested in a tool that makes the job easier. My friends ask me where to buy the hydraulic expander but I cannot...

What are the symptoms of a blocked cap tube? Pressure, temp difference, icing on tube?

I got the hydraulic expander. It splits 3/8 and smaller but works fine on larger. A great tool if you use it right. Everyone who has seen it wants one, but for some reason I never see it on ebay any...

Thanks for the responses, it is kind of what I thought after I did an Internet search looking at refrigerant identification. I guess shoddy work is not just for residential HVAC.

I was asked to look at a customers walk in beer coolers. There are two identical units side by side. One has a hot shot label on it. The other is unmarked. I told the owner that I could not be sure...

Thanks, the supply house faxed me the wiring diagram. the other fan timer failed because the 24 volt wiring was wrong. It is a pain but I like it when I find something differant, makes me learn...

I post this here because for some reason I cannot get into the pro forum.


Hi, I am working on a RUUD oil fired hot air furnace. The unit is going off on limit due to failure of the fan timer not...

It is made by GB Instruments model GVD505A. I got it at Lowes

I have seven different meters on my van that I use for specific applications. I have used a voltage stick before but it only senses the general emf in the area. This one does have a wide narrow...

Am I doing something wrong here, every time I ask a question the answer I get back is assuming that I don’t know what I am doing. I am licensed for refrigeration, gas and oil heat.

Does anyone else use the Live Wire voltage detector? I bought one and it makes electrical trouble shooting a breeze. On a electrical cord I can adjust it so I can tell what side of the cord is hot...

I see several products sold for testing acid levels in AC systems. Do you have a preferred product that is easy to use and the results are accurate?

Please ignore my post about cutting the suction line, it makes no sense since I am not cutting the suction line. It was late on a holiday and had a few. I do like the idea of using nitrogen to blow...

The Sporlan rep called me back today. He said there is only one maker of coils who offer a kit for installing a TXV on an older coil and you need to make flares to use it. He seemed to favor drilling...
