The cost of replacing an AC compressor can vary depending on several factors, such as the type of compressor, the make and model of the air conditioning system, and the location. On average, the cost of a new AC compressor and its installation can range from $1,000 to $2,500 or more. However, it's important to note that this is just a general estimate, and the actual cost can vary significantly based on the factors mentioned above.
As for the installation process, it can take several hours to complete, depending on the complexity of the system and any additional work required. In some cases, the installation may be completed within a day, while more complex installations or those requiring additional repairs or modifications may take longer.
To get an accurate estimate of the cost and installation time for your specific situation, it's best to contact a reputable HVAC professional who can assess your system, provide a detailed quote, and give you a more precise timeline based on your circumstances.
