An air conditioner's compressor in Blue Diamond will have a price that will vary a lot based on the specific model and the unit's sizing. As a rough estimate, I might peg the compressor at around $300 to $1,200. If we assume that the same amount of money will be put towards professional installation, then we can guess that the entire project, compressor and installation, will run anywhere from $700 to $2,700. So, on average, an air conditioner's compressor will cost from a low of about $300 to a high of around $1,200, and if it is installed improperly, then you may have to pay the low sum of $700 in labor to a person who knows what they're doing.
