We Appreciate Our Customers Feedback!
"These guys are great! I spoke with them after hours and they fit me in for the next day. Not only that, they fit me in first thing in the morning. I was told previously that unit would have to be replaced, and they were able to determine the problem right away and repair, minimum time and minimum expense. They know their stuff. I highly recommend and will call them again if ever needed. Save time and money, CALL DUCOLD FIRST!"
