🌎 On Earth Day, the focus is often on big ideas, but in our world, it’s the everyday decisions that matter most. How systems are designed. How they’re maintained. How they perform over time. We’re always keeping an eye on ways buildings can operate more efficiently and sharing what’s worth knowing along the way.

Cooling season may still be weeks away — but the smartest time to prepare your HVAC system is NOW. ⏰

Planning your spring start-up early helps:

• Reduce unexpected downtime
• Improve energy efficiency
• Extend equipment lifespan
• Keep occupants comfortable when temperatures rise

At AT Mechanical, preventive maintenance is about more than routine service. It’s about preparing your system to perform when it matters most.

🌡Smarter cooling starts now.

One of the most common mechanical clashes we see on projects: Ductwork vs. Structural framing.

It looks simple on a 2D drawing — until a main trunk line runs directly into a beam or truss in the field. The result? Field rerouting, duct resizing, added fittings, lost labor hours, and schedule impact.

Early 3D coordination between mechanical and structural models helps identify clearance conflicts before fabrication begins — protecting both schedule and budget.

Coordination isn’t just about avoiding clashes. It’s about building systems that fit the first time.
