Ambient temp 76
indoor temp 73
supply temp 66
Suction pressure 55
discharge pressure 155
this is a cap tube system
I notice grugling at Evaporator coil
My house is between 2700 and 2800 sq ft.
I think this is under sized but the system is not preforming

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. :-)

Why is suction and discharge lines of Goodman WMC24-1A split ac system freezing up.?


Low on freon, dirty evap, dirty filter or maybe restricted at the metering device

Goodman unit runs and at the a-coil there is a piston where your suction and liquid lines connect. On the liquid side the piston is cold but warm on the other side of piston. A/C unit will not cool.


That piston is the metering device. On the liquid line, before the metering device it is always warm (this is sub cooled, high pressure liquid), but should flash to low pressure, lower temperature vapor once it passes through the metering device. The suction and liquid line never connect together.The liquid line brings liquid from the condenser to the evaporator. The suction line brings super heated vapor from the evaporator to the compressor. Since the unit does run, I'd have to put a gauge on it,but if I had to guess, I'd guess you have high head pressure. Check for dirt or debris on the condenser, check for proper clearance of the condensing unit and check for operation and directional rotation of the condenser fan. This could also be the result of an over charge.

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.

Bad condenser unit GOODMAN


it is a 3 ton condensor you still can buy r22 freon condensors new but they have nitrogen charge and its expensive to charge I recommend to go with 3 ton goodman condensor which is new 410a puron and also change indoor coil and flush the line set so you dont endure the high cost of new copper lines these new systems come with 10 years warranty and the r22 systems come with only five years

Missing insulaton on the suction line.


You would not get liquid refrigerant back to the compressor because of missing insulation. Please let me know if you need any further assistance.

Have goodman unit, ac unit running 55 suction, 210 high side. cleaned condenser coils and charge to 10 degrees supercool. suction at 65, discharge 245, why did my discharge go so high


You should have liquid line filter/dryer that maybe restricted or there is a restriction in the orfice inside the evap coil normal operating pressures are 68/ 180

Need line set size for goodman ck-36-1a


If your running gas heat it's 5/8 3/8 tubing.If it's elec. heat it's 3/4 3/8 tubing. Etheirway 3/4 3/8 works for both. Use 6 wire for tstat from tstat to furnace or air handler, and you need is 2 wire from condensing unit [outside] to furnace or air handler or anything more than two.

The suction line temp is 90 to 95 and drops down to about 68 on a residential unit checked the evap. it wasn't dirty flushed drain line wanted to know what could possibly be causing such a thing


Check the Liquid line drier. Make sure the temperature on either side of the drier is the SAME.
If there is no drier, and there is an expansion valve installed in the air handler, then it might be "hunting" or have some trash or non-condensibles in the lines. The Liquid line must be in the low to mid 200psi range. Is the condensor coil clean? It must be.
Also is the filter new and not too restirctive? Don't use one of those 3 month filters. Think about this, if it is so good, and lasts 3 months, then each month, it gets loaded more and more. Imagine the particulates collected over a 3 month period!
Hope this helps.
God Bless.
