Ac compressor turns on but hot air and doesn't seem like clutch is disengaging what could cause this?

What you're asking really requires a more in-depth diagnosis. There are seven operating conditions of an air conditioning system, based on what the system pressures are in accordance to the pressure/temperature relationship.
Condition one is normal operation, while the remaining six result in insufficient cooling.
The possible reasons why you're not getting adequate cooling out of your AC system can vary. Low refrigerant is the one people like to assume is the reason, and it is a pretty common one. But, DIYers tend to typically just throw a can of refrigerant into the system, and fail to understand why that "fix" doesn't last for any duration of time. If you've lost refrigerant, then you have a leak in the system, and need to repair it if you don't want it to be a recurring problem. I work in a shop which has equipment to evacuate and recover refrigerant, so that's the first thing I do.. then I see the amount of refrigerant recovered vs. what's supposed to be in the system.. if what I recover is substantially lower than what's supposed to be in the system, then I perform a leak test by charging the system with compressed nitrogen through a manifold gauge set, and spraying the AC lines and fittings with a soap and water mixture.. keep in mind that, while a lot of people use the soap and water method, it is not recommended if you're not going to pressurize the system (like I do with the nitrogen) - if the leak is on the low (vacuum) side of the system, that soap and water can end up in the AC system, and your problems increase significantly at that point... pressurizing the system with 250psi of nitrogen retards the vaccum, prohibiting this from happening.
Other possible reasons for your problem could include fault low or high pressure switches, excess refrigerant and/or PAG oil, a faulty compressor clutch, electrical problems, blockage in the system...
This type of work really isn't a DIY task, and I'd recommend you seek the services of a professional.

What would cause the gearshift on a 1995 Chevrolet Lumina to be hard to move?
The clutch might not be completely disengaging.
Will oiling clutch on ac compressor help?
Oiling the a/c clutch will cause the clutch to slip and burn up........
91 Honda civic air conditioning compressor clutch turns on an off?
Assuming this is a factory installed a/c system and not an aftermarket one, there are several possibilities for the clutch engaging and disengaging. When the compressor cycles off, do both fans go off at the same time? The clutch and fans should work together in a properly operating system. The airconditioner routinely would cycle on and off in a good system to prevent the evaporator core from forming ice on the cooling fins and blocking airflow. If the clutch only cycles on and off and the fans remain running, a wiring problem say at the connection to the clutch or the thermal switch on the compressor itself may be defective. Another possibility is that the clutch coil is developing an "open circuit" but cycle times of the clutch engaging and disengaging would be fairly long. I'm sure there are more things that may cause your problem but these are good places to start looking.
Already changed fuse and air conditioning compressor clutch assembly but no power going to cause the compressor to kick on to pull back the clutch so that compressor kicks on what could be the cause?
What specific kind of vehicle do you have? It does sound like the clutch may be bad, but we also need to know what you are working on. You need to run power straight from the battery to the compressor. If is still does not engage then you need to replace the compressor and clutch, they are dead. If they do engage, then you have a wiring or computer issue.
What wires cause an air compressor to stop turning on a 1989 Mazda mx6?
I'm Guessing that your talking about the A/C compressor, in which there are 1 or 2 wires going to the clutch. Disconnecting this wire(or 2) will disable the compressor clutch stopping the compressor from working.
What would cause AC compressor to not run on 96 sunfire - no blown fuses but no power on green wire to the compressor clutch?
Maybe the compressor clutch is not being sent power from the switch in the cab. I'd yank the panel out and have a look at the switch. FriPilot
Can the ac compressor clutch cause low engine idol if turning when ac is turned off?
Yes, if the compressor's bearings are bad, usually accompanied by a roaring or squealing noise coming from the compressor's pulley.
Your ac will not come on a 1987 Chevy Celebrity what can you check for?
Low or no freon will cause the AC not to work. Also if the clutch on the AC compressor has failed, or if the compressor itself failed.
Why is my 1997 Ford Explorer XLT Manual hard to shift gears in 1st 2nd and 3rd sometimes?
The most likely cause is provably clutch related. It sounds like your clutch is not completely disengaging. Check the fluid level, then check the slave cylinder
1992 Jeep Wrangler gears grind when being shifted and the rpms have to be about 2500 before you can shift without grinding all fluids have been checked What can cause that?
I would suspect a weak clutch slave cylinder or clutch master cylinder which may be preventing the clutch from disengaging fully; The slave cylinder is connected hydraulically to the clutch master cylinder. The clutch master is where you add fluid.
How do you unfreeze the clutch on a 2002 ranger?
If the clutch is froze, I assume disengagment is the problem. Check the freeplay, or if it is hydraulic, check to see if linkage is disengaging the throwout bearing. Unless you know what you are doing, take your ranger in to an A.S.E. certified auto technician. A faulty clutch system can cause serious damage and injury to you and other's.
What can cause a truck clutch pedal to keep falling to the floor?
If the pedal just randomly falls to the floor, you probably have a broken pedal or linkage. If we are talking about it having no resistance when you press it and the clutch not disengaging, you probably have a leak in your clutch hydraulics. This can be a bad master or slave cylinder, or a leaky line. Bleed the clutch, and then keep checking the fluid daily to see if you are losing it.
