No cooling, suction pressure reads vacuum Split AC

Recharging of the refrigerant was done and run for couple or hours, but after sometime, there was no cooling and the suction pressure drops to negative.

The unit is restricted, reprocess the system, flush and vacuum it thoroughly.

No cooling, suction pressure reads vacuum Split AC - dc22de9d-d16a-4c66-83c5-c89d4a34abb8.pngIf the unit runs normally and then goes to a vacuum and the refrigeration effect quits than you have a leak, a pretty good sixed one that should not be too tough to fix, the best way to deal with this today is a sealant, its about $50 if you do it.
If it was restricted the unit would not cool and then quit unless it has a floater, a particle that clogs the metering device briefly etc or a obstructed filter dryer etc

    If the Sub cooling is near 10-15F and the low side pulls to a vacum while high side stays high, is restricted, if you lose the head pressure /temperature or around ambient plus 30F converted to PSI then the sytem is low on refrigerant.

WHAT IS PSI SUCTION PRESSURE IN SPLIT AC WHEN UNIT IS IN OFF CONDITION


there is no suction at all when the machine is off as the gas equalizes around the system
all you will read is the pressure of the gas in the system and that will tell you nothing
to read gas pressures you need to know the type of gas in the system , have gauges that can handle the high pressures and have two on a manifold so that you can read suction and high side pressure differences
That way you can see if the system is low on gas or over charged

A/c will not cool


have you removeing the filter from the front of it sometimes colecting all that dust in it can cause it send only luke warm air out also if youve had it on none stop it can sometimes freeze but then letting it sit for a couple hours to a day usually solves that

I have a dailkool split ac my split is not cooling well as compared to the cooling when i buy??so there is a problem of compresser or the gas of compressor


The only way to know if the unit is low on gas is to take pressure readings referring to pt chart for the type of refrigerant the unit uses. doubt it is the compressor. Also check the condensing unit if the coil is dirt covered in bugs or cotton wood your unit will run with high head pressure and not be as efficient.

Hi, I need to relocate the split air conditioner, but I don't know the first step and next steps. Thank you,


If you are not a service technician you probably won't have the tools you will need to accomplish the move. Here is what it takes, step bye step. 1. Pull the fuses or turn off the electrical breaker in the house. 2. Hook up a gauge manifold to the Condensing unit ports for the liquid and suction lines. 3. Hook up a Refrigerant recovery machine to the manifold. 4. Recover the refrigerant into recovery tanks down to a trace, no vacuum. 5. Disconnect the electrical whip and control wiring from the condenser. 6. Close off the service valves on the liquid and suction lines at the condenser. 7. Slowly unscrew the copper line connections to the condensing unit to relieve any pressure that may exist from Refrigerant boiling out of the oil in the compressor and quickly cap them. 8. Move the unit to your new, firm and level location. 9. Remove the old electrical disconnect and whip and move it to the condenser. 10. Buy a new line set of the proper length or extend the old one with Refrigeration copper and couplings preserving the condenser couplings. 11. Replace the liquid line drier and reconnect the copper lines to the condensing unit. Replace the "O" Rings if needed to insure a good seal. 12. Hook up a vacuum pump to your gauge manifold. 13. Open the isolation valves on the condenser. Depending on the oil type in the system, evacuate to 250 Microns. 13. Charge system with 50 pounds of Nitrogen and a little Refrigerant for a trace test. 14. Watch your gauges for a drop in pressure indicating a leak. 15. Check all fittings and any splices with a good Halogen gas detector. 16. Evacuate the system again to the point of vaporization of the oil in the compressor being careful not to boil it off. 17. Close off all ports on your manifold and install a small drier to your Refrigerant line. 18. Re-install the recovered Refrigerant, running it through the small drier on your manifold. 19. Re-check for leaks. 20. Install the electrical whip on the contacter and the control wires on the contacter coil. 21.Start the AC and check the running amps against the name plate Full Load Amps (FLA) or Regular Load Amps (RLA) and check the Refrigerant charge against the units chart. Either in your owners manual or glued to the electrical access cover.
Method 2 = Instead of recovering the refrigerant, you can pump it into the condensing unit. With your gauge manifold tied in, close the liquid line isolation valve. Run the compressor till the compound gauge reads 1 pound and close the suction line isolation valve. Doing it this way will eliminate the need for the recovery machine and heavy tanks. All else remains the same.
Special tools needed = Compound gauge (meaning it reads both pressure and vacuum). High pressure gauge, gauge manifold and at least 3 hoses, a vacuum pump, leak detector (or soap bubbles) and an amp probe. Please rate this response. Thanks for asking!

Air not cold enough to cool house


Make sure the outside fan is running. Also check the high side pressure, I assume the 70# is the low side pressure, so you can tell what the compressor is doing. If the fan and compressor are both working, make sure there is good airflow through outdoor coil and check that it is clean. Let me know what you find.

Need an expert on Grunaire Mini-split systems. Need troubleshooting guidance - compressor will not run -only fan comes on. Get a ''P8'' error. I thought it was due to low refrigerant. I had to install 35...


If you are low on refrigerant, and if you have a low pressure switch, it will not allow the compressor to come on in heat or cool, until you put a jumper across the low pressure switch or add enough refrigerant to get the pressure up to close the switch. You can only add refrigerant to a system if the bottle pressure is higher than the unit pressure without the compressor running.
Normally a technician will hook his gages up if suspects the unit is low on charge or he will push the contacts closed on the contactor and feel the suction line to see if it's cold.

AC not cooling during the day


Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

One head freezes


You are short of refrigerant, the evaporators (heads) run in series and if you run short of refrigerant one of them will have reduced or no cooling depending on the amount of refrigerant left in the system. You should make sure that a leak in the system is found before just recharging the system or you will have to do it again in the near future.

Extremely high head and suction pressures


disconnect the blower and turn on the ac.see if the coil frosts evenly.when you had the system open,you should have changed the liquid line drier.

Split system wont cool


Check your service valve if open, check for kink piping or system clug up. But check also your refrigerant charge if adequate.by monitoring the suction pressure and current reading.
