Exactly how much refrigerant did you charge into the system when you recharged it? If the suction pressure is varying that much you most likely over charged the system and got a liquid flood back which took out the compressor valves.

Whatis ideal r22 gas pressure required in 1 ton split ac of BlueStar.


Doesn't matter how big the unit is, pressures remain the same. On a satisfied temperature, approximately 75 degrees, r22 should be around 65 psi. The hotter the house, the higher the pressure. Head pressure varies on outdoor temperature. 90 degrees outdoor temp, approximately 200 to 225 psi on high side.

1.ton ac capillary pipe size and length I want to know. B coz suction line cooling level is very low gass psi 75


I'm guessing you should have 3/8 & 5/8 copper on that unit with a maximum of 50 feet. I doubt the line set size is affecting your pressures that significantly, you likely have a leak.

Lennox troubleshootingI have a lennox split evaporator on the ground condenser 3 stories upI have 75 psi suction at evaporator and a 25 pressure drop at the condenserneeds a hot gaz ??is this normal lines...


indicates insufficient gas
for gas lines of that length extra gas is required
Best have the system charged by an ac specialist shop as the pressures are not correct and gas is added according to high pressure and suction pressures

High low side pressures and sight glass contains lots of bubbles


The system has a lot of air in it. If u haven't had any AC wk done on it that mean there is a leak in the system. System must be evacuated, pressurized & find the leak. Repair the leak, vacuum air from system & charge w proper AC gas. SPECIALIZED EQUIPTMENT & GAUGES NEEDED. good luck

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.

1998 Jetta TDI - AC compressor turns but no cooling


something not right here ,firstly why didnt you just renew the clutch instead of a complete compressor ?? secondly do you have a machine to recharge the system and if so are you using it correctly ,the reason i ask is because in the machine the low and high pressure pipes are interconnected in the body of the machine so yes it would show these pressures.When refilling a car once machine has weighed the gas leaving the bottle shut off the red line and start engine leaving the blue line connected ,run engine at 2000rpm with A/C on full for about 3 mins to draw the gas in from the machine .Then close blue line and and do a recovery to see how much gas was left in the machine.Also did you put compressor oil in when you re fitted the compressor about 100cc is enough ,this is better put in directly into compressor ,then vacumn to about -750mg or a stage one vac pump and omit the oil recovery cycle .When running the air temperature coming out should be about 7.5centigrade is good but some cars will drop to 5C anything below 9C is ok ,and forget to clean out pollen filter

1997 tahoe wont start


it is not the regulator if it has 40 lbs of pressure try to pinch off the return line and if pressure drops quickly it is either the check valve in the pump or the rubber seal between the pump and the sending unit
