No, if refrigerant is not metering properly it is because there is a problem with the metering device (either blockage of an orfice or failure of a thermal expansion valve) also if the system is low it may only be feeding vapor instead of liquid.

My Goodman condenser which was recently replaced is making a severe swashing noise when it stops. Like a back flush or something. Need to know if this standard.

Normally if it does not sound right, it is not right. By your discription it sounds like your compressor is having a problem with flood back caused by a txv not metering properly, or an overcharged system. You will need a tech who can determine superheat and subcool for your refrigerant system. Find a tech who can determine these values. Superheat and subcool is normally around 8 -12 degrees. Superheat is the amount of additional heat the refrigerant picks up in the evaporator once it is turned to gas and is needed to keep liquid refrigerant from flooding back to the compressor. Compressor are designed to compress gas not liquid. Subcool is the additional cooling refrigerant undergoes once the refrigerant turns back into into liquid in the conderser. Subcool ensures the refrigerant remains in liquid form until it reaches the metering device. Only liquid suppied metering devices will pass the required amount of refrigerant to achieve the rated cooing or heating rates. If it is liquid flood back, your compressor will be damaged and will need to be replaced. Hope this helps

Can i replace only wall split system head with different brand

I wouldn't recommend it, because of capacity, refrigerant type, and functionality. For example, heat pump condensing unit can only be matched with a heat pump air handler and must use the same type of metering device on the inside unit. It can be done, but would have to be done by a qualified tech. Why chance problems. Besides, you'll void the warranty.

Will goodman outdoor ac work with bryant indoor unit

This is true as long as it is not a heat pump. Make sure they replace the piston (metering device to match the outdoor units required piston size. Or if the indoor coil is metered via TXV, it will automatically meter the refrigerant flow. If you are mismatching a system, make sure an acid test is performed on the old refrigerant and take appropriate measures with the new system if the test shows positive acid. They need to definitely install a liquid line drier.

One of my indoor air handlers makes a lot of condensation and it's not even on. I was told that it might be the metering device not closing to 80% or it's not wired properly. For now the customer is...

If it's not running, the pressures would equalize over a matter of a few minutes. While your still flashing liquid in the metering device, it would not have a continuous supply of refrigerant. Even if the TXV was closed 80%, you would freeze the top of your coil because as soon as it meters through the expantion valve, your refrigeration saturation would drop off the chart and you woulf freeze as soon as it's metered. You need to got to the unit and amp out the compressor. Isolate it. You want nothing else but the power to the compressor. You could have a welded conactor. I have installed Fujitsu units and the comressors run very quite. Any noise around will over ride the sound of the compressor. Let me know what you find out.

Goodman Condensor cplj48-1 Air handler Modle

It sounds undercharged (needs more refrigerant). Based on the conditions in your post and assuming the indoor humidity is within 20-70% range, your target superheat should be 10degF. Your superheat (assuming you have an R22 system) is far too high. The pressures are not indicating a restriction; therefore, I have to conclude you have a low charge. A low charge will cause a gurgling sound due to the refrigerant in the liquid line is vaporizing prior to reaching the Cap tube at the Air Handler.

I hope you find this information helpful to you moving forward. :-)

Air handler too large for heat pump doesnt heat or cool properly any options to get unit to prefrom better like pistons or txv

I would check with the manufacturer and check on the right sized air handler. The txv or piston has been engineered to function with the system you have and this will change the dynamics of your system by altering the metering device.

Bubbling water sound in AC. Water in the tray is cold. Unit continues to make a gurgling sound.

The gurgling sound is the liquid refrigerant going through the refrigeration copper lines , it's normal. And the water in the tray is condensation and is cold because is from the circulating air that gets cold going through the air handler(inside unit) You only has to keep the drain clean ,by pouring 1/2 cup of clorox every 3 or 4 months.

Themostat problem no power

Your R terminal in your air-handler is the 24v power that goes to the tstat. Look at the air-handler and match the color wire. ALL tstats have a power wire going to them. If you aren't getting power, you probably have a break somewhere in the wiring close to the thermostat you are replacing.
