I understand how a two stage system work. But why two speeds on a signal stage?

Hey Brent, I just received my Imanifold and it is sick. What do you think or heard of that works best with the Imanifold for Bluetooth rang, iPad mini or samsong tab 3,4. I need to buy a new tab just...

Yea that kinda sucks. Start looking you need to get your hands dirty.

If your getting your own license it would be helpful to learn the office side of things. I would wait it out intill you finish school and then look for a better job with more pay. Then ask your boss...

Thanks. By the way are they adjustable? What would cause it to close when the box temp is 28* instead of 38* low on charg or overcharg?

Is it common for the vavle to be in the evaporator ?

Hey guys I need help understanding how the temp controls work on the htpg evaporator model sla37-30 I can not find any real info. The condenser unit is located on the roof. It has a low pressor cut...

This looks pretty cool but it seems like it's not using the spd2 full capabillitys. Is the app going to be improved to show RH values, what about delta T across evap coil and enthalpy. Will it be...

I have the sman 460, don't know what to do. It sounds like this phone app is going to replace the hg3 in know time at all. So not going to get the hg3. Really want the sdp2 and an STA2 In-Duct...

I know this is an old thread but dose the hg3 have btu output yet.

So what's the word.

So I should hold off on a hg3. Do you guys think this will replace the hg3?
How many tools will the app allow. It would be nice if the app would do a total btu output calulation and then show a...

I'll take it give me a call and we will work it out 9168328656

I have around 16 amps at the comps, rla is 24. I did separate the coils to clean them.

Yea it's been around 85* in Sacramento the last few days, already had a poorly maintained 12 year old 12 ton trane voyager unit trip the breaker.
Cleaned coils check air flow, check amp draw took...

Hey thanks, I like that app.

Hey thanks for the great answer. You the man!

Just mainly r 410.
Let's say it's 78* outside and my liquid line is at 300psi which is 96* sp.
Liquid line temp is at 86* so I have a 10* sub cooling MF name plate calls for 10* sub cooling so...

You put gauges on to find out your head pressure. WOW. Really! You don't hafe to answer a question if you think it's stuipid. Why waste your time.
This is why techs who want to learn don't post...

Hey guys, just had a quick question. I always here or read about high head pressor, but I don't know how techs determine it's high head pressure? Yea sure you have a drity condenser coil and its 99...

Hey guys, need some help.
My neighbors had a tech over today and he put in 2 pounds of r22 in and said they were low on freon. When I got home he ask me to take a look, because it still wasn't...

Hey guys, bought a sman3 a few months ago, only used it about 10 times so far. It is a great tool!! Anyways now it does not show my subcooling, it will show my sh , temps lsp, vsp, idwb. Idwb, real...

I would say there are alot of hvac guys who need to learn how to read a meter.

Some systems are not protected by a fuse, i like the transformer idea. This is a tool more for entry level guys, i guess the point would be to prevent techs from shorting out conpoinents.

Hey guys

Let me know what u think of this tool ive come up with.

We are talking about r410a by the way

I know he has no clue but before i tell him that i would like one good reason why its wrong beside we all know its wrong. He has said if the coil is 35* then the air coming across it will be cold and...

Hey guys,
Heres the deal one of the higher up is telling the new guys to charge the system by just the low side temp to get the temp to around 35* or so. If its under add freeon if is over recover,...

Thanks for that input. So qhat do you think about the charg. On the subcooling side

I think the jb pumps are a good deal. Which one is it. Just so you know some do not come with blank off valve.
