Nice job!! Wondering if you fabricate TDC joints also?

You can install a pressure / temp logger. This logger will monitor pressure and temp so when you come back you know what really happened and when. SUPCO makes low price loggers perfect for this...

Every A/C system must have a charging procedure and chart provided by the manufacturer. Always follow manufacturers data.

The only way to get it real clean is to remove the coil, apply chemical cleaner an then rinse with lots of water.

If you do it right you don't have to do it twice. :D

So now the customer will know how much refrigerant is leaking .01 oz/year.

Maybe customers can choose the scent they like.
I suggest dollar bill scent, then you will know how much you have to...

Cap tube systems shall be charged using the Superheat method

Expansion valve systems shall be charged using the Subcooling method

Nope!! That's overcurrent protection !!!

I always recommend 3 phase monitors (new installs or when replacing a compressor) It's a cheap insurance for the customer. Low cost vs. high protection.

What is a micron?
A micron is a metric measure and is defined as 1 millionth of a meter or 1 thousandth of a millimeter.

How often do you get to 350 and hold for one minute? What kind of vacuum setup you use?

Do you use stainless steel flex hoses or the heavy duty black ones?

igwt777

if you are pulling to 500 you are on the safe side.

Welcome to HVAC-Talk

You will understand that type of answers on the run!!! :D

Always pull down to 500 microns and replace filter driers. This will save you lots of time. Do it well the first time... then you don't have to come back and do it again.;)

IMO I keep the 3 phase units.

Never seen a minisplit whith heating device.

Now looks better!!

Now i understand why he was driving so fast.... battery power was low, he must recharge before it goes dead.

As you can see, safety is #1 !!

We used FORTO red non acid coil cleaner.

It shure is. Payson, haven't you removed one of your Goodman's 5Ton "A" cooling coils ? One of my guys took both sheetmetal plates out (front and back) to get this coil real clean, Thats why you see...

Customer claim they repace filter every week.

No. This guy was driving very fast and changing lanes. I took this picture at 9am , and by the way he was driving I guess he must finish those installs by noon. LOL

I agree with you guys.

I just can't think how a customer can close a deal with "contractors" like this.

I needed to post one more!!

Very nice and clean job!!

sorry, pictures were deleted. I will try to post again.

IMO all ductless are about the same we have plenty here in the island. My choice is McQuay for ductless this are very easy to service. Sanyo are good also but parts are to tight and there is no room...

I always cut both flare fittings and then braze using couplings. I dont think 200 psi of nitro will hurt that coil, but always follow manufacturers instructions.

There are other ways to know if your system is properly charged. If the suction line sweat or not, will not tell anything.

Try this

You can pump down a system to 300 microns and still have a leak. The key is if your system vacuum level does not rise above 1000 microns, then you can call it a "thight system" not a leak free...

I use a manifold with two 3/8 stainless hoses connected to the Core Removal tool. The micron meter is connected between the system and the manifold, not at the vac pump.

Here is a link

Thats a Fluke 52 series, welcome back to the real tools!!

I agree with square2round. Also i will add a good nitro "blow" between vac pull. (triple evacuation method)

I always use fesh air. That will call for incresed cooling capacity.

john dalton,

You are correct, I went to far in my last post.
