I've been working with JN Electrical Temperature Control, Inc. for about a year, now, and have definitely been completely satisfied. They've been in multiple times to tend to my restaurant's refrigerators, and we've had them in for the HVAC unit, as well. They're always just perfect, really. They arrive soon after we call them and have always been well-prepared and ready to solve the problem(s). They're reliable and have consistently provided prompt, professional service so I'd absolutely recommend them to others.
