Each burnout leaves trash for the next compressor to deal with, almost like a welcome basket from hell. There have been too many in that system, time to change it out.

If this machine is running unloaded, The coil would be frozen at this point, and you would have noticed that for sure. With a suction pressure in the 60's, we can all take for granted that the...

Laborer means ductboy to me anyway. :)

Stopped up pistons act like misfeeding txv's, low suction, high superheat, high subcooling. Sometimes you have to break out something others than your guages and temp meter!:)

Well, if it is in there, and is affecting the system negatively, you would have high superheat and subcooling. If it isnt affecting these things, and you still want to know, a 5/16th nutdriver, 2...

JP, I wouldnt swap the unit out until I had the static pressure tested. With variable speed air handlers, there may be a duct issue going on.

With a regular motor, the rpm's will turn at 1075 and...

In my opinion, Goodmans are not a bad thing, but not a good one either. Here on the coast of North Carolina, the goodmans are not great in a latent capacity. The design of them are more sensible than...

Fieldpiece sc76, and a cooper temp meter. Fielpiece is by far the best out there. Flukes are for Kooks!:)

What superheat do you have on the suction line?

When a txv is udes before a piston, the piston does restrict the refrigerant flow. A piston is designed to meter refrigerant based on the liquid line pressure. If your pressure is 225, then the...
