Providers of Innovative Mechanical Services

We can take your project from a concept to a finished project. At JS3, we have the expertise, skills and partnerships to make your commercial or industrial idea a realization. From plumbing and gas piping to ductwork and HVAC equipment we have you covered. We love the whole process of getting to know each other and working side by side through a 1-day or multiyear project. Projects really come down to figuring out what is important to the customer so we can find several options to fit their needs.

We can take an old and inefficient piece of equipment out and put in a new and efficient piece of equipment. We work with local principalities and organizations to get you a financial kickback on your projects. Anyone can replace a piece of equipment but it takes a special eye for details to make the entire system/building work better. Our customers love that our projects include a holistic approach to solving their issues for great comfort, reliability and efficiency.

Nothing makes recurring maintenance and service more powerful than communication and attention to detail. JS3 communicates every step of the way by promptly getting a tech dispatched, looking at the whole system rather than just the first apparent problem, photo documentation, a conversation on what we found, and providing ideas to increase your bottom line by minimizing issues and unplanned repairs. While most companies check to make sure the equipment is FUNCTIONAL, we check to ensure equipment is PERFORMING. We provide you with a written report on the exact performance of your equipment. Do you know if you are getting full performance out of your systems? Is your equipment operating at rated capacity? Is your mechanical contractor tracking performance to predict when cleanings or services need to happen? JS3’s extensive commercial and industrial mechanical coverings include boilers, chillers, pumps, water systems, cooling towers, package units, split systems, VRF/VRV, VFD’s, parking garage systems, and built-up systems. In a nutshell, if it heats, cools and moves water or air we can do it.

We do controls differently. The traditional “HVAC controls” industry is reactive and is not capable of automatically learning from each site. Plus, how often do you have to call your traditional DDC controls contractor because something isn’t quite right or they missed some logic while meticulously setting up every single block of logic? We partner with control manufacturers that have controls automatically tracking and watching performance. When a piece of equipment’s performance is decreasing you get an alert. When any system wide component failure happens you get an immediate alert. You no longer have to worry about a “DDC Technician” missing logic or waiting for a call from your personnel that something isn’t working. Let’s get ahead of things together!
