If the unit has been serviced recently, there could be an overcharge of refrigerant, non condensibles in the system, clogged metering device screen, or as you stated a restriction somewhere in the system, the system needs to be recovered, drier changed, metering device inspected/changed and recharged

Where is the AC drain line for a 2004 xc90?

If the a/c runs for 10-15 minutes and then blows worm, it would not be the drain line.

Check and see if the outside blower ( cooling ) fans are engaging.

If they are not running, the unit will run into a high pressure overload and open power connection to the compressor.

Also, you may want to check the Freon level.

Won't build top pressure an shut off

It sounds like your pressure switch is not set correctly. It is possible it is set too high for the compressor you have.

When you change from heat to air , it still blowes hot air like it is not switching to air conditing, the compressure is running and lines get cold, but no cold air. thanks

If the orifice filter is clogged, this will happen, a better check can

be done with an ac manifold gauge set, the low side reads the

evaporator pressure and the high side reads the discharge

pressure. I had the same problem while checking the ac on a

2000 gmc 1500 z71 4x4. other things that could cause this are

to much oil in the ac compressor or not enough freon in the

system. an overcharged system , the best way to check it is with

a gauge that way you can tell if you have the right amount of freon

and oil in the system. plus the gauge set will let you know the

extent of your problem. good luck!

My compressor runs and builds pressure but, with nothing touched all of a sudden does not produce the same amount of pressure as before, it will not run my printing machine. What should I check?

Does the compressor have enough CFM to run the printing machine. Will the compressor build up pressure and shut off if you close the discharge valve at the tank. Your printing machine may simply be using to much air. If the above items are not the case you may have a faulty check valve in the receiver tank or valves going bad in the LP or HP heads. The valves may also simply have carbon build up or dirt of some type not allowing the valves to seat properly. I would start at the check valve. One way to check the check valve is to see if you have air blowing from the bleed off line at the pressure switch all the time. Another way to check is loosen the fitting at the High Pressure head an see if you have air blowing continously. Caution do not remove the fitting at the head completely. If the check valve is bad you will have high pressure air blowing until the receiver tank is drained.

99 Toyota Tacoma a/c reads high pressure on low pressure side

Does the compressor run?
Low side could be high without a running compressor.

A running compressor?
The expansion valve itself is about $50 and bolts in.
You will have to remove the 134a gas before installing a replacement expansion valve and vacuum the system before recharging.

A/C unit in 2007 Dodge Durango

Yep,I'd agree. The difference in coldness is unrelated to the compressor issue. That a bad vent motor or something like that on the heater box in front. Change the "h" valve or otherwise known as the "expansion" valve too.
