A/c compressor on my 88 camry

whenever i use the a/c on the 88 camry it blows hot air unless you drivering very fastg when the vechile is idleing it seem to heat up agian you can hear the compressor cyle on and offf so that would mean the compressor needs replacing right? and also when i replace it do i need to get a new recever dryer and fliter for it?

The problem might be that the AC system is low on refrigerant. Have the AC system tested for the state of chrage before condeming the compressor.
