Is there pressure in the high side? equalize the high/low sides pressure thru the use of gages and start the compressor and take note. The condensor valves should be opened to the evaporator, both high and lowsides

check the true psi with the line psi to see if same if psi is good in cooling 225 hi and 70 low on 80'day then compressor is fine and i would start checking for temp difference on the reversing valve sometimes this will cause high suction or high discharge psi shift it manually with by energising it be cooling or heating then pull wire and see how it shifts if shifts good then txv on out door unit could be bad what is the psi in heating on the discharge line going to the indoor unit? most prv's are set at about 350 psi r22 as for suction line size its only hot gas in hp mode os no problem their shows in cooling mode as low suction psi ..hope this helps some also make sure indoor coil is clean!....thanks & rate me

make sure coil and fan are clean and getting good air flow thru the coil and not bypassing it if discharge psi ok air flow problem if high then somthing in unit stopped up some have screens in the liquid line at the coil hope this helps also make sure fan is going the right way! on indoor unit repost psi and temp readings on both lines and indoor and out door temps thanks

Hi,
Being that you had the same problem before I would guess that it is not the filter or TXV that is the problem...
You may have another restriction in the system...
Did it work in heat mode???
Do you have adequate air flow???
Is the coil and filter clean??
Did you try to purge nitrogen through the piping when you changed the TXV???

This really sounds like an air flow problem more then anything else...

R22 unit running at 160/58. Took bulb out climbed to 61 on suction then right back to 58. Replaced txv. Charged to 220 head, suction stays at 60. Clean coil, no filter, good airflow. Ideas?????


Sounds like bad valves in the compressor.
A good indicator is how fast the pressure changes when you shut the compressor off. It should take several seconds for the suction pressure to rise. If it's immediate, then expect a bad valve.

Heat pump with High head pressure


HFC-134a ? Critical pressure is 588.9 a . With a 93 LL temp and 575 head, I would suspect 1. Air in system or 2. Ref. has gone critical.
With a 110 psig suction/85 deg.F and a LL temp of 93 deg.F/125 psig

1.5 ton straight cool condenser....head pressure good at 250 psig....suction pressure will not go higher than 55 psig....target superheat indicates target suction pressure at 68 psig....o/d coil clean,...


Hello take a evap coil split (return temp vs supply temp) 18*F would be great.If it is lousy the TXV valve is restricting the flow of freon or the filter drier is clogging.Adding freon will overcharge the system and the suction will NOT improve.

I have a goodman CPF42-5f split system tripping Hp switch after running for a little time (test hp tripping @ 430psi )both coils have be cleaned


I assume the fan is running in the outdoor unit. Do you have guages connected to the unit? What is the suction pressure when in trips? There could be a restriction in the refrigerant line. Suction pressure would be low if this is the case. Check the temperature on both sides of any filter/driers. A difference in temperature from one end to the other would indicate it's restricted. The same would go for any component in a refrigerant line. Did someone add refrigerant recently? If the unit has a TXV it could be overcharged. It's also possible for a TXV to go bad. Hope this helps. This problem is hard to solve without seeing the unit.

My adp coil already failed in my only 2.5 yr. Old Carrier ac unit. I am now looking at an estimated $1500.00 repair. Coil is under warranty so the above cost reflects labor only. Adp serial #7107A07780....


Sorry, I don't have any solution but I'm in the process of replacing my 2 AC systems (4 tons by York). My RUUD dealer has provided RUUD ac and gas furnace with ADP coil and not using RUUD coil. Should I insist on using RUUD coil rather than ADP coil?
Thanks,

Carrier air con. expansion valve 5 problems and 5 solutions


1. Mid to late 90's problems on Carrier coils leaking. 2. Problem with lication of TXV's on air handlers. When welded in they were located to close to the fitting where the suction lines were welded in to unit. The heat would cause them to fail.

I am working on a carrier package roof top unit about a 5 ton. My head pressure is a little low and my suction is double what it should be. I cannot valve off the unit to try a pump down to check txv. How...


you could always disconnect the sensing bulb and warm it up see if the pressures change or i would squirt some refrigerant in and get your head pressure where it should be and see what happens with the low side hope this will help?

13 degree Delta T


I assume r-22 refrigerant by the pressure... you have a saturate temperature of approximately 41 degree and 71 degrees at the service port this equates to a 30 degree superheat. a condenser saturation temperature of 105 degrees and since the liquid line temp at the service valve is not given only the enterin indoor coil on the liquid line a 96 degree temperature this would equate to a subcooling temperatureof about nine degrees. You have too high of a superheat reading. verify that the bulb for the txv is correctly positioned and insulated. if it is then you need to remove the bulb from the suction line, hold it in your hand to warm it up and see if the superheat changes. you could also have issues with your ductwork. If the supply temperture is around 50-55 degrees then the unit is doing all it can.. Check the txv and the ductwork as the subcooling indicates that the condenser side is doing it's job, but the superheat readings indicate that you are starving the evaporator..
