disappointed in NATE techs

[BamaCool]

Sounds to me that no tech that steps foot in your house has a chance, no matter how well qualified he is

What is it the OP said that gave you that impression?

Have a service tech check your charge.

The charge has always checked out fine.

Has any tech checked static pressure?

It's true that I don't completely trust what I can't verify for myself, but that doesn't stop me from making a decision. I chose to have the compressor replaced, and it's pulling the proper amps now. It's been too warm here to see if the line set vibration is cured.

By static pressure, I guess you mean the air handler? I asked one of the NATE techs to check the pressure drop across the coil, and he said he could do that by comparing the room air temperature to the temperature of the air coming out of the nearest register. He seemed to think the temp checked out OK.

Someone doesn't have a Manometer in their truck

Don't judge NATE by 2 Techs

Did they check it by pressures only, or by super heat and sub cool.

Nope, he can't, not possible.
