Oct 03, 2020 · Clogged Cabin Filter. A cabin air filter is responsible for filtering the air that enters the vehicle’s air conditioning system. The filter catches all the dust and impurities that enter the passenger compartment and can, therefore, become clogged over time. Jul 05, 2020 · Possibility #2 AC low side pressure is too high because there’s air in the system. An AC system is a closed system. If you’re low on refrigerant it’s because you have a leak. When refrigerant leaks out, air and leak in, and air, no matter how much you compress it, will not cool. Jun 10, 2020 · The AC system in your car could go through all sorts of problems. One typical issue is the unit not blowing cold air, which could be punishing in hot weather. There could be several causes leading to this condition including compressor issues, low-level of refrigerant, trouble with the heater or AC controls, and others. Start the engine and set the A/C controls to max A/C, medium blower speed and recirculating air. Allow the system to run for five minutes for pressures to stabilize. Normal gauge readings will be between 30 and 45 psi on the low side, and 200 to 350 psi on the high side. The expansion valve can fail in one of two ways. The condenser was 150 in and 105 out. Is this a good temperature drop. I was thinking that the lower temp while driving was due to longer high engine speed dropping the low side pressure and thusly the refrigerant temp is cooler. But it is still not cold. The compressor is not cycling. Mar 05, 2015 · The vents may not be blowing warm air, but the air does not seem as cool as it should be given the temperature setting. Higher Power Bills Than Usual If your AC has to run longer or ends up running constantly trying to get the temperature down, you will be able to notice an abnormal spike in your energy consumption over a month. Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI Refrigerant charge quantity for air conditioners & heat pumps: This air conditioning repair article series discusses the the diagnosis and correction of abnormal air conditioner refrigerant line pressures as a means for evaluating the condition of the air conditioner compressor motor, which in turn, is a step in how we evaluate and correct lost or reduced air conditioner cooling capacity. Feb 15, 2020 · You will need to remove some coolant from the AC system to get your pressure readings back to normal ranges. This can be done by yourself with a few tools, or you can bring your car to the auto shop. Jul 23, 2020 · Here is a list of the pressure readings that are characteristic of an A/C compressor that is not blowing cold air into the cabin of your car: 250 PSI / 30 PSI = You have air somewhere in the system. 250 PSI / 50 PSI = The system is overcharged and the condenser is not cooling. Condenser may be blocked. 225 PSI / 80 PSI = It is likely that the expansion valve is opened too wide (not the case if your A/C system has an orifice tube) Also, you could have too much refrigerant in the system. Actual pressure will depend on the type refrigerant and the ambient temperature and does not show if the system is properly charged. At 85 degrees Fahrenheit, R134A shows a pressure of around 90 pounds per square inch. Much lower readings suggest the system is low on charge or contaminated with air. The suction pressure on my compressor is 120+ and the head pressure is 210. But the unit is not cooling. Is the problem with the compressor? The auction pressure is high and the discharge not normal. It should be in the range of 350 to 400. It is likely that the problem is with a compressor valve.

This can be done by yourself with a few tools, or you can bring your car to the auto shop. Sep 23, 2007 · The pressure was OK ( I remember around 80 psi ) when he checked with his gage. Now the unit does not cool at all. Compressor fan is not blowing warm air to the outside. The 2 pipes that enter the evaporator in the attic are not cold either. Apr 15, 2012 · I have about 11 years split system in Dallas. Coil is in the attic and condensor is outside. The pipe used to be cold when A/C was on. When my pipe was nailed by a roofer and fixed last year, I asked the A/C guy why the pipe was not cold any more and he said it'd be still okay. The house was cooling anyway. I survied last year summer with the unit. May 27, 2016 · Standing pressure actually makes me go back to the expansion valve being bad. If it is open all the time, then the compressor is pressurizing the entire system, which would cause the low side to go high until the pressure switch kicks if off. It also fits with the earlier symptoms of the AC randomly not working before it went out completely. Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI So your car air conditioning not cold?
