GWIN HVAC: Built Like a Tank. Engineered for Real-World Performance.
At Freedom HVAC Supply, we carry GWIN HVAC systems because they deliver durability, performance, and real-world reliability that stand up to the harshest conditions. From voltage fluctuations to outdoor moisture and corrosion, GWIN systems are designed to thrive where others fail — all while keeping installation simple and affordable.
Durability & Performance — The GWIN Advantage
Built Like a Tank
At GWIN, we know your HVAC system has to stand the test of time, the elements, and real-world conditions. That’s why we incorporate premium engineering features usually reserved for commercial units — and deliver them in our DIY-friendly design.
Weather-Resistant Control Board
Our system features a vertically mounted control board that’s pre-coated for corrosion resistance and moisture protection. This unique design helps shed water, reduce debris buildup, and extend the life of your PCB — meaning fewer failures and longer-lasting performance.
Wide-Range Input Voltage Capability
Power fluctuations are common in older homes, rural areas, and during storms. GWIN systems handle it all, tolerating a 165V–265V input range to prevent electrical damage and ensure smooth startup and operation under variable conditions.
Low-Voltage Startup Resilience
Many HVAC systems struggle to start under low voltage, leading to compressor strain or short cycling. GWIN designs its systems for rugged startup performance, protecting key components and ensuring reliable heating and cooling even in imperfect power environments.
The Result: A System That Lasts
What you get is more than just a “DIY-friendly” system — you get one that performs like a professional-grade install, built to last years longer under challenging real-world conditions.
Introducing GWIN DIY+ Hybrid Installation
Our GWIN DIY+ program gives you the best of both worlds — the cost savings of a do-it-yourself project with the assurance of professional expertise and warranty protection.
- DIY-Friendly Setup: You handle the accessible, non-technical installation steps.
- Certified Pro Inspection: A GWIN-certified technician verifies, seals, charges, and optimizes your system for peak performance.
- Full Warranty Coverage: DIY+ installs qualify for the exact same warranty as fully pro-installed systems.
This approach saves thousands in labor while ensuring your system performs at its best — no shortcuts, no compromises.
