What is wrong with your air conditioner when the low side pressure is 90 and the high side is 240?

What is the outdoor temp? If above 90 this is typical pressures. It sounds as if you have a dirty filter or some other restriction. Possibly a dirty condenser coil or evap coil. >>>>> This means it is HOT in the house, assuming R-22 is the refrigerant. A dirty filter would not cause this.

What would cause the low side on an air conditioner to be too high?
When you say too high, just how high is it and what is the high side pressure. It is not uncommon for the suction pressure(lowside) to get up to 80psi on a very hot day. You cannot determine what is wrong unless more information is provided. It could be that your system is overcharged, but without the high side pressure and the temp of the suction line it is hard to give the right answer.

Where are the air conditioner high pressure and low pressure valves on a 1995 Chevrolet blazer?
The low-pressure fitting is on the side of the accumulator, at the back left corner of the engine compartment. (Standing in front of the truck, looking towards the back.) The high pressure is just below and in front of the accumulator. Generally speaking, on all cars the low side will have larger diameter pipes than the high side. The fittings on modern cars (running 134a) are slightly different sizes, which makes connecting to the wrong one virtually impossible.

What should pressure reading be for house ac?
