The HVAC and refrigeration industry is undergoing a major transition with the phase-down of high-global warming potential (GWP) refrigerants. In 2025, new regulations will require businesses to shift towards A2L refrigerants, a new class of low-GWP, mildly flammable refrigerants designed to comply with environmental standards while maintaining energy efficiency.

When it comes to managing your building’s HVAC systems, knowledge is power — and asking the right questions during service visits can save you time, money, and future headaches. Whether you're responsible for a single facility or a portfolio of buildings, understanding the current condition and performance of your HVAC equipment is key to ensuring comfort, efficiency, and longevity.

Whether you're managing a cold storage facility, an ice rink, a hospital, or a manufacturing plant, your systems are critical to daily operations. When equipment fails, the clock starts ticking — and the cost of unplanned downtime quickly adds up. That’s where spare parts come in.
