It's hard these days to find someone who is trustworthy, professional, reliable and provides outstanding service at a reasonable price. Synergy by far exceeded my expectations. They showed up on time and even called ahead to advise they were on their way. The technician, by far the best I've ever dealt with, effectively troubleshoot my furnace issue and to my surprise fully detailed all the steps he took in the invoice and explaining everything in a manner I could understand.

Just had ultra Guelph replace our trouble maker old air conditioner with a new unit. Very satisfied with the process as they provided up to 5 options for me and educated me to choose the right unit at a very fair price. Installers were great. Highly recommended them for their service. Looking forward to the summer now!
