I used a small can of some green leak detector in a tiny aerosol can and it managed to seal a leaky micro coil ( R410a) at a slightly lower pressure. Not looking for DIY advice ,more of a commentary...

Not better but it will work. I doubt it 2 1/2 uf will give you any problems. Of course it's better to order the right part.
Voltage increase sure. I know it's not Mfg authorized but if you are in a...

I think the next size up is 45-10. I would use that. Better to go next size up. It will store slightly more charge with the tiny increase in cap value. Nothing to worry about. Current draw is I(C) =...

I would not rule out an insect. From a non pro.

I had problems in Florida with mold on siding. The only solution I found which could penetrate the vinyl is to use mobile home white stuff and follow with bleach solution. Bleach solution or mold...

I would re-seat those LTC tranceiver dips with deoxit D5. You could also look for a test spec document from the Mfg if they will part with it if they even documented it.
DOS 3.2 386 these guys...

Propper dark blue Tactical tough and comfortable.

It looks like they took a bigger piece of copper and use pliers to make a makeshift connector and brazed the whole thing together. Something you would see in Mexico.

Just wondering.. most mobile homes have a packaged unit outside. It seems like you could just build a platform under the trailer and fit an evaporator there and a condenser outside if trailer not...

I have to wonder if you cannot use R410a in place of R32 if you cannot get R32. I'm sure it's not the best option and efficiency would drop but I wonder. I bet it would work. Not a pro. I just got a...

Is that a 12,000 BTU unit ?

Hello Guys:

Does anybody know which pins are the filament heater on the 4510 sensor (Thermo super Vac-check 14571) ? I think it is:
Heater 1 White wire, B+ pins 1-2
Heater 2 Black wire ...

Everything you need to become enlightened you can learn from George Carlin.

Only to the unread. The American Press has a long history of self censorship. To the uninformed it would seem like funny paranoia. Any moderated post could be suspect, reasonable to assume the worst...

FYI, yes been here around 2012 for a short while then off for 5 years then on for 30 days.

Most differential communication signals can be tested by other means than a scope. I would start with the signal then determine the best instrument. Rs-232, RS-422 not really an analog waveform. All...

[QUOTE=3.14;25565662]The problem you’re describing has to do mostly with the corrosive effect of arcing when the points are closing or opening.

The ark is caused by the potential between one side...

Some things you can bootstrap yourself on but AC systems .. Just a window unit being made took over 2 mil ( kickstart) and 16k orders for it to work. Cost a lot to certify unit.

I will not argue against that. Contractors place a bid and probably the cheap guy wins.

Been there :

Your words : " all built about the same" says it all. I'm not going to argue against that statement.

You are right: Players with a lot of money can compete.

Mr Bill:

I don't know I'm not a mechanical Engineer. I tend to believe if they can make a rocket engine to pump liquid Ox at great pressure they can build a coil to withstand 800 psi and...

It's an example of a big box/ sears and consumer brand monopoly. There are options go to better dealers which offer better equipment. Not a total monopoly but a market segment monopoly.

Next time you go to the big box store or sears note the low quality of riding lawnmower engines. 500 hr engines. 20 years ago you could buy a Kohler pro engine which would give you 2000 hrs. Today...

You are right in the sense of we are stuck with what we got and have to live with it. Well the mandate goes to everyone and the the stock market will drive the market offering. You cannot argue with...

No, the customer has no control over what is presented in the market. There is no evidence that quality cost too much.
If there is only low quality the public has no choice but to live...

The government says you must provide an efficiency but does not say quality must be bad. Compliance with efficiency yes. Hr says you must hire a minority but they do not say you must hire a STUPID...

You got a point. Better to pay more now than pay a lot more later.

Hiring practices is a political decision, again a mandate for a product does not imply an or function. You can have both.

Quality is no longer a primary design mandate -- True
Compliance with DOE requirements - True

Whatever has to be sacrificed for DOE - False Not end of story , End of THEIR story.

Quality - AND...

No not complain, inquire about state of quality and try not to get ripped off so much. I'm leaning towards a Panasonic mini split more expensive. I really like Japanese build quality if I can get...

Rigol - had no idea scam vaporware. The Chinese always have some kind of time bomb take back in anything they build.

Just seen an updated Nordyne by chance at a dealer and the units are about 30% smaller. Tiny fans coils. Guy says the fans sound like a jet. So they shaved the materials and upped the speed. It was a...

There are Techs and then there are super Techs. The super Techs constantly read constantly learn take all the free classes offered and often are as good as Engineers or some better. If there is a...

Hard to justify more than $700 for HVAC scope use. Buy something expensive somebody could steal it. One of those things I would not leave on a service truck. The Rigol 4 channel for $400 great price.

I know they are cheap and will treat them as such. If one goes I toss that part of the system.

Sorry I jumped the gun later noticed you already pulled the trigger. Difficult problem being portable. Rooftop. Sunshine. I can tell you .. Fluke quality is good, meters are the best. For scopes...

I'm not part of the HVAC Industry but the Test and Measurement Industry. I would suggest the Rigol DS 1052E sent to your door by Amazon for $252. Within your budget. Flukes are known for their DMMs...

The thought control police remove any real problem discussion critical of Manufactures so this site is Corporate censored. I'm out of here.

Yea they may just average out over time to be minimum and the new standard. There is a reason why one company has so many brands and that is the illusion of choice and marketing. You can pawn off...

Some .. people do not like discussion of design to fail Engineering because it's not Politically correct thinking. Some claim it does no good since it's out of our control. Perhaps so but censorship...

No I don't think so sounds too noisy. It sounds like a refinement of existing old thermo technology without any refined control mechanical feedback loops like use of TXV for control of superheat and...

It does. The Chinese tried to pass their best attempt compressor but was rejected - 3k btu, bad eff. People in the city with a view would buy this who have older Apts. The carrier worked well with a...

I hear Trane sample test rather than ATE test every unit so some slip through. I'll keep Trane and it's clone in mind.

I agree. If they built a great unit and it came with parts and labor 15 years then they would be forced to build a good one or go out of business. Warranty is a form of insurance scam, devil in the...
