Does too much refrigerant make air hotter?
Instead, you know that having too much refrigerant in the system can actually make the air hotter. The extra refrigerant puts more wear on the compressor, and this extra work can cause it to overheat which kicks it off. Also, the extra pressure from the Freon can cause the compressor to start pooling oil inside of it.
