I don't think you can put the orifice in backwards. Because of its coned shape it may only fit one way. Although if it were to be in backwards then the gasket would not be set so the liquid would slip around the orifice hole and therefore it would not flash off correctly. You will probably see problems on the blue suction gauge. It would give you symptoms of flooding at the indoor coil.

Air conditioning is weak


I will explain a few things about air conditioning and a possible rework using a $12 part. An orifice tube is part of some Air conditioners. The cheap ones are $3, but a self-adjust orifice for areas of 105 Degree heat are available. If done with a Freon Recovery machine, Freon costs will be minimal. It takes a special tool to change the part, but you could get the High Temp orifice online and find a place to switch it. Vacuum pumping is advised before refill.
Second, the best amount of Freon is a moderate charge. You have 2 cut-off switches one for low and one for high. This means the compressor will cut off when either extreme is reached. The recommended amount of Freon fill is what the Factory has determined. So many ounces per Label.
Air flow. You could just have a blocked Air flap under the dash or a Solenoid that is not turning the flap fully open. What you could do is try a used car on a lot and see how the blower works.
Fan speed resistor. If you have Digital Climate Control, this is an almost infinite speed regulator. Part of it could be burned out and even if the duct flaps are working properly, you won't get the push out of the system. Or it may have a part called a Solar switch which works with Climate Control and the other switches.
So if the Shop checked the Freon charge and it was Okay, there are still the additional items I mentioned which can affect the performance of the Air Conditioner. Again, check car lots for used cars to start up and check A/C performance.

HE heat pump won't talk with old air handler?


The fact is, the air handler supplies the voltage, blower, and electric heat. In order for the heat pump to work correctly, the wiring from the thermostat and heat pump need to be hooked up right to the air handler. The thermostat is what tells which component to come on. If the fan stops, but the condenser keeps going, you either have a faulty fan relay on the air handler, faulty thermostat or wiring, faulty wiring at the heat pump, or the contacts on the new unit are sticking, which is highly doubtful considering it is working now. I hope I have helped you understand this a little more. Good luck and don't let them push you around, get someone that knows what they are looking at.

My 1995 Chevy Silverado blows cool air then warm air. It goes back and forth between cool and warm.


You have a flow restriction,the orifice tube,(inline filter) on the low side(suction)a/c hose.Check close by the dryer and lines for freezing over,if so evacuate,then flush a/c system,install new orifice tube and recharge with new oil and freon.

What is the purpose, and what is the proper location of the orifice tube in the air conditioning system on my 1991 chevy silverado?


The orifice tube restricts the flow of refrigerant to the evaporator. This restriction allows high pressure liquid freon to change into low pressure freon before entering the evaporator. The orifice tube is located inside the hose running between the condenser and the evaporator. You'll need an orifice tube removal kit if you are looking to remove it.

Ac cycles on 92 blazer ,new compressor,low switch bad?


Did you replace the dryer,and the orifice tube?If the orifice tube was not replaced,this is most likely the problem,what are the pressures while it is running,and how much freon is in the system?If the system does not have enough freon it it,it will do this,but if it does,the cycling ac compressor is because of the orifice tube,if the system was not flushed out,and there was a new orifice tube installed ,then it is stopped up again.Let me know something so I can help.

I put in three cans of refridgerant and the ac didn't get cool. Did I put enough in or do I have a leak?


You may have a stopped up orifice tube,feel of the large ac line going into the firewall,see if it is cold,if it is,then the inside door for the temp is not working,but if the ac line is not cold,remove the freon and remove the orifice tube and clean it,or replace it,then charge the system back up.If this was at all helpful,please rate,thank you.

Which way does the orifice tube go? Orange end or white end to the firewall?


9 is the orifice. Freon is headed toward the evaporator in the car. The orifice has an arrow on it. Good luck, please rate. Thanks A/C Evaporator Core Orifice NOTE: The A/C evaporator core orifice (19D990) should be replaced whenever an A/C compressor (19703) is replaced.

The A/C evaporator core orifice has the following characteristics:
  • is color-coded orange
  • has a diameter of 1.46 mm (0.058 inch)
  • is located in the condenser to evaporator tube (19835)
  • has filter screens located on the inlet and outlet ends of the tube body
The A/C evaporator core orifice is the restriction in the refrigerant circuit that creates the pressure drop necessary for cooling by metering the flow of liquid refrigerant into the A/C evaporator core (19860), which reduces the pressure. Operation is as follows:
  • The inlet filter screen acts as a strainer for the liquid refrigerant flowing through the A/C evaporator core orifice.
  • O-rings on the A/C evaporator core orifice prevent the high-pressure liquid refrigerant from bypassing the A/C evaporator core orifice .
  • Adjustment or services cannot be made to the A/C evaporator core orifice assembly. It must be replaced as a unit.

The front A/C blows cold but the back A/C is not. the condenser is not even getting cold


The rear ac has an orifice tube. This restricts the flow of freon.if orifice tube is blown through or the little screen is plugged with compressor debris it will not work correctly. Some ac systems use a expansion valve same purpose but the little valve can get stuck open and just allow freon to flow through.

Goodman 3 1/2 ton unit


I work for a very large reputable goodman dealer. Your equipment appears to be a correct match. The correct orfice should have been taped to the outside of the outdoor unit in a baggie right beside where the pipes connect. Things will run alot smoother though if you scrap the orfice and have a TXV installed (thermal expansion valve) . This is a mechanical device that adjusts the flow of freon into the indoor coil based on the immediate needs of the coil. After that, balancing the refrigerant is a piece of cake as all we need is about 10 degrees of subcooling to make sure we have plenty of liquid to the TXV.
