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...
I went to the Sprolan site; nowhere do they talk about how to attach the equalizer line.
Kind of like the people who sell Pex tubing for hydronic baseboard heating, no where do they talk about how...
Thanks I figured that when I have the suction line cut to install the valve I would use my one-gallon wet vac and attach it to the suction line when drilling the hole for the equalizer line. That...
First I do have a call into the Sporlan tech line but the holiday is a delay.
I do have all the latest equipment, and more that most HVAC techs have. I am a tech I think.?(who cares)
I am sorry I...
I was hoping for a little more advice than what line it goes on. Like the location of the equalizer line (on the suction line) and do you use a fitting or drill a hole and braze it on.
When adding a TXV valve to an existing A-coil, and advice on how to and where the equalizer line should be connected.
I did belong it was great but the chapter is in another state. Now with the price of gas what it is, not feasible.

Yes I agree, it makes no sense, this was an insurance claim. The existing unit was a heat pump that was being used for AC only, on a gas furnace. I asked for a condenser but the insurance company...
Ok thanks. Can I energize the valve using O and the two contactor wires that run out to the unit? If so what goes were?
Without the wiring diagram I am lost.
I understand standard AC, heat pumps are not used in my area. Is there a web site available for this unit which I could see a wiring diagram and get a clear picture of what is being said here. The...
I just replaced a 3-ton heat pump. The office of the company I work for told me to replace it with another HP even though it was being used only for an AC condenser.
The unit replaced was a old...
Thanks for the offer lbjheat, but this company insists they supply the equipment for me. I never gave compressor change outs much thought regarding 13 seer because I figured I would replace the evap...
I was told today there are no more 10 seer units from my supply house. This means replacement of all existing R22 condensers will be 13 seer. What condenser information does one use to obtain the...
A fresh air intake does quiet the burner down quite a bit. From the posts I have read it sounds like your equipment is not the problem, the people working on it are making it a problem.

I found this link very informative.

Now that is what I am looking for. The only question I would have is, when using this set up on a TXV valve, would I still be reading the high side when closing the valves, what is the chance the TXV...
It is time to get ready for the warm weather. I want a set up to use my micron gauge on both the suction and discharge lines at the same time. I am really not interested in using copper to do this I...
I asked because a diagram that I saw was confusing and I was unable to locate any specific information on the net. I would think that if you measured with the t-stat in the loop the heat anticipator...
When taking a amp. reading to set your heat anticipator on a T87 should the t stat be in or out of the circut. I am looking a a diagram of the procedure and it is not clear where they are taking the...
I just went through a major hassle with Nordyne. I had to install a roof jack. The vent pipe would not fit into the roof jack. The distributor told me I was not doing it right. The lady on the phone...
Just to be clear this condensation problem is occurring during the AC season with the heat off.
good point, never thought about all the oil to gas conversions that are going on due to the high cost of oil.
I never paid much attention to it, but now that I look, I have serviced 2 houses with oil fired heat that are using B vent for chimneys.
As far as this condensation problem, the customer said it...
Everyone calls it B vent, the code calls for type L vent. Is it the same?
Mobile homes use roof jacks.
I went to service a oil fired furnace the other day. When I arrived I noticed that there was significant condensation in the flue exhaust and evidence of condensation dripping on the floor and onto...
