Jonathan Crawford replaced an entire a/c unit on a rental property and was prompt and reliable. He and his company, Cold Fusion Mechanical, are second to none.

Great overall experience from beginning to end. Jon is professional, courteous, efficient and explained the technical aspects so even a dummy like me understood. He was all done by noon and we couldn't be happier! Thanks Jon

Jonathan's attention to detail is unsurpassed. You won't find a contractor with his expertise at such reasonable prices.

Jon and cold fusion is simply the best company in this trade group. PERIOD. Their attention to detail was unbelievable. They caught an error in one of our units and gave me the data to go back to the installer who agreed to redo the work for free. This company is honest, technician knowledgeable, and timely, courteous and respectful. If you consider working with another company in Arizona...you made a mistake.

Honesty, integrity, professionalism, craftsmanship and skill are just a few words that sum up Jonathan Crawford and Cold Fusion Mechanical.

Jonathan relentless searched for a leak we had that no one else could find or fix. Very pleased with his work.

John from Cold Fusion was extremely knowledgeable. His service was top of the line, he was prompted and fixed my A/C quickly. I would recommend Cold Fusion to everyone who is looking for an honest A/C company. ❤️❤️❤️

Very happy with the service we got from Cold Fusion Mechanical! Jon did a great job. I highly recommend!!

Very impressed with the speed of communication and am happy with the service and advice Jon provided.
