This is also correct, we are bringing our rolling shop to you. There is a lot of cost involved.

Your not being charged labor for the use of the recovery machine, vacuum pump and torch, ect.
Its the cost of purchasing and maintaining the equipment and the cost of disposal fees, oil, gas, ect....
Its a removable appliance.
Damn fine work.
I agree, I don't see the problem either.

A lot of latent heat needs to be removed before I would draw any conclusions.
Glad to see you back posting too.
Changed out 6 of those this year on an old Walmart, 4 still worked.
Your grip on his what?
Same here but most cities are wise to unlicensed contractors having the homeowner pull the permit. They question homeowner and have them sign an affidavit that their doing the work themselves, and...
Only means you have some subcooling.
Looks just like some Apartments around here I have done work for. I'm sure the evaporator coil is plugged with dirt and hair.
Is the coil above the electric furnace? If so its original and the...
You said you were the tech, what do you mean the sight glass is flashing too?
You'll be lucky to get 12 SEER out of system if not set up properly.
You have to get the airflow right before you check charge. Do you know how to check total external static pressure and use fan curve chart to get CFM's?
Especially when you use a 3 ton air handler...
The 50' liquid line is the metering device.
:grin2:Took me a minute to get it, duh.
Low pressure cut-in cut-out switch.
Someone must have thought it was a refrigeration condenser with a liquid line solenoid.
So in Cali a licensed contractor can't pull permits, the homeowner has to?
What about new construction or if the customer is commercial property?
Yeah, I vote for bad TXV too.
I hear that, probably one of the worst things about working for yourself. Hard to tell long time customers and landlords no.
I worked for a three man shop years ago, we did one week on two off. Two...
Instead of squeezing the runner openings closed open them just a little and use a small wire to clean the runner opening. Or try moving the one that is giving you a problem to the first one by the...
I think I understand, the sun during the day heats the surface of the planet with radiant heat which warms the air at the surface, so when the sun sets the heat radiates from the surface {ground} so...
I would agree with redhash, looks way overcharged. The condenser coils are stacked with liquid that's why you only have a 5* temp rise, its not transferring much heat.
Don't get the 74psi suction...
Yes if the amp draw is off on a new motor I learned to move it up or down. Seems like the sweet spot is usually with the middle of the blade at the bottom of the cowling.
No, your right this time.
That's exactly what I kept arguing in another thread. But I did some research and talked to ICP rep and called Copland, seems they left something out of the Scroll's for a time that if the thermostat...
That's what electrical tape is for.
Good point, show him the video and explain when it does it you can shut it off and when you turn it back on it runs normal.
Only problem is 95% of tech's won't ever think about a single phase Scroll...
The motor in the compressor.
Oh, and we only help homeowners from the Great North. You Canadians scare us, have to be half crazy and half wild to live up there, :grin2:
Have your tech check for anything that can cause unit to stop momentarily, its known as short cycling. If you don't have one get a thermostat with built in compressor protection that has a 5 minute...
Triple evac doesn't take that long if you already have nitrogen right there from brazing. Nitrogen is a dry inert gas so it helps by absorbing some of the moisture.
He does that to me a lot too.:grin2:
Same thing I've always done, sometimes hard to tell if you have enough extra wire to get to where insulation or wire isn't discolored. I've known I didn't have enough wire but cut back as far as I...
timebuilder:
Am I right that when a wire burns off the terminal and melts the insulation the physical properties of the wire is altered causing resistance?
I always replace the wire that burnt not...
The most common exam is the Experior/Block test.
Very hard, you should see if a local Jr. College gives prep classes.
Mr. Bill is right, when the wire burnt the first time the heat damaged the whole wire not just the end where the insulation was burnt off.
Thanks, exact answer I was looking for. No one ever believes that pulling a fast vacuum will freeze the moisture.
Every body brags about how fast they can pull a 500 micron vacuum on a 2 ton system.
Wondered about that too, air would still blow in right direction. Just not too much.:grin2:
Thank you, nobody seems to advocate triple evac anymore. Please explain why pulling one fast deep vacuum doesn't get out all the water vapor.
[I have tried.]
Your not just doing the callback for free but they charge the tech too?
That's the truth, around here supply houses are pushing Nu22[422b], when I ask about 407c or equipment they look puzzled.
That's what I thought too, he said it was going out on overload.
Nothing to do with LRA rating.
NEC section 440 deals with compressors and motors.
The data plate on the condensing unit gives you,
Minimum Circuit Ampacity rating, this is what you size the wire...
That's not true when it comes to compressor's and motors.
The Minimum Ampacity rating on data plate tells you what size wire to run according to 310.16 of the NEC.
Maximum Overcurent Protection...
How long ago did you buy the house? If you had a home inspection done the inspector should have checked to see if the AC was cooling, if so the home warranty co. should cover it. If its been less...
Everybody had to change their password so that's not it. PM a mod.
That was Truck, he was disrespectful to other members and the forum in general, thought he knew more that everybody else. Me and another member yanked his chain till he went of the deep end.
He came...
Might be restriction at service valve, that would cause the suction line to frost between there and compressor. Is there a suction line filter by any chance?
Check line temp on both sides of service...
Sounds like you have an airflow problem, check the evap coil to see if its dirty.
At 55psi the coil and suction line is going to frost then freeze.
10 to 1 the indoor coil is plugged with...
If you can figure out how to get proper airflow I think you would have it whipped. A 2.5 ton package should be able to push 1200 cfm at TESP of .53 you say you have.
