This year we celebrate 20 years in business - and I couldn’t be more grateful and proud to work with my family. Over the past three years, with the support of our clients and partners we have raised over $270,000 for the Les Turner ALS Foundation - a cause that is deeply personal. Thank you to everyone who’s been part of this journey!
This year marks a milestone for us at Sun Mechanical Systems — 20 years in business. Two decades built on hard work, heart, and the dedication of an incredible team. One of the ways we celebrated this anniversary was through our annual Les Turner ALS Foundation, a cause that is deeply personal to us. Thanks to the generosity of everyone who came out, supported, and gave so selflessly, we raised $73,000 that day — and with additional contributions after the check was written, the total climbed to over $110,000. The impact of this support cannot be overstated, and we are beyond grateful. A huge thank you to our Sun team — not only for the work you put in every day to make 20 years possible, but also for the energy and effort that went into making this event such a success. We are humbled, grateful, and proud to continue this journey together. Here’s to building on 20 years and making a difference where it matters most. #SunMechanicalSystems #SunMech #20YearsStrong #LesTurnerALSFoundation #ALSGolfOuting #Gratitude #Community #Teamwork #MakingADifference

Sometimes the best team bonding happens spontaneously. 🍅🥒🍻 Today our crew set up an impromptu Bloody Mary bar (with plenty of snacks to go along with it!) — a fun way to take a quick break, share a laugh, and recharge before heading back to the work at hand. It’s little moments like these that remind us: building strong teams isn’t just about projects and deadlines, it’s also about connection, culture, and celebrating each other. Here’s to hard work, great people, and making space for both! 👏 #SunMechanicalSystems #SunMechSys #TeamCulture #PeopleFirst #EmployeeEngagement #WorkplaceWellbeing #ConstructionLife #TeamBonding

Proud to have provided and installed the sheet metal ductwork at the Keystone Trade Center in Fairless Hills, PA! Our scope included installing 3 exhaust fans and duct systems serving battery charging stations for forklift operations—ensuring proper ventilation and compliance for safe, efficient operations. A big shoutout to our fabrication partner Sheet Metal Werks, Inc. for their support—pre-installing registers into the ductwork helped streamline installation and boost project efficiency. And thank you Anthony Del Fava for always supporting the Sun Mechanical Systems team—both locally and nationally. #SheetMetal #HVAC #Construction #Fabrication #ProjectSuccess #Teamwork #IndustrialVentilation #BatteryChargingSafety #MechanicalContractor #SunMechanicalSystems
Common question : "Why would you tag customers/contractors in your posts, aren't you making it easy for your competition to poach?" My response: I build relationships based on trust & results.. Our contractors know they can count on Sheet Metal Werks, Inc. and because of that, I don't concern myself with what my competition does. With that being said..... John Schillace of Sun Mechanical Systems has put his trust in Sheet Metal Werks, Inc. time & time again to make his jobs run smoother. This job heading to the East Coast is no different. 7 units worth of duct & fittings, 94 registers shop installed without a single list ticket from the field foreman. Everything was done off the coordinated shop drawings provided by Sun and all material will be shipped to the site on 1 semi with color coded labels & wrap . This upfront coordination will make installation a breeze! Thanks for the trust John!!

We’re excited to welcome Hunter Wickland, P.E., our new Lead Engineer here at Sun Mechanical! He’ll be working alongside Chris Scoville and Ben Lynam on our engineering team! Hunter is a mechanical engineer with a broad background in HVAC and plumbing design across commercial, industrial, education, healthcare, residential, and geothermal projects. His passion lies in analyzing and solving problems while developing creative improvements for clients’ existing systems and controls. Before moving into mechanical design, Hunter spent over eight years in the mining and construction industry in Texas and Wyoming. His roles included equipment engineer, maintenance planner, and supervisor—giving him a deep understanding of how to keep large, complex systems running smoothly. Hunter was drawn to Sun’s impressive large-scale, design-build HVAC projects and our commitment to delivering excellent results. But what really sealed the deal was the team itself—Hunter values working with great people, and he was excited by our collaborative, growth-oriented culture. He’s also new to the area (again), having just moved back from Wyoming! Outside the office, Hunter enjoys tackling DIY projects, both around the house and in the garage. He’s an outdoor enthusiast, into both summer and winter sports—fishing, water sports, and especially motorsports. He also loves playing and listening to music, and spending time with family and friends. Welcome to the team Hunter!
