We had a couple of broken refrigerators and needed them up and running asap to continue with our Restaurant business. Sebastien has been extremely professional and knowledgeable right from the beginning. We were advised to change the compressor for our walk in cooler. Sebastien make some changes and saved us thousands of dollars. Highly recommended, please don’t waste your time and money anywhere else.
