The Evolution of DIY Mini Splits
GWIN™ Assisted DIY™
Most DIY mini splits still leave the hardest parts up to you — pressure testing, vacuuming the system, handling refrigerant, or finding your own tech, and even dealing with bulky pre-charged line sets. GWIN™ HVAC changes all of that with Assisted DIY™. The GWIN Assisted DIY 14,000 BTU 22 SEER2 230V Two-Zone Ductless Mini-Split Complete System (18k condenser,7K + 7K Wall Mount) with 15 foot line set and communication wire with Assisted DIY™ is an evolution over DIY alone and makes GWIN™ a complete DIY mini split system that includes free expert tech support, with a tech included, so you never need special tools, never touch refrigerant, never run a vacuum pump, and never perform a pressure test. Our line sets with our easy connect flare-less fittings, allow for a professional operating system, with a professional look. Which also means no coiled mess and no guesswork — just a straightforward self-install ductless system that goes in like a true DIY HVACproject, backed by professionals every step of the way. Whether you're cooling or heating a garage, basement, bedroom, sunroom, home addition, tiny home, or cabin — GWIN™ HVAC is the ultimate DIY ductless solution with our Assisted DIY™ for homeowners who want to do it themselves, but done right."

The Evolution of DIY Mini Splits
GWIN™ Assisted DIY™
Most DIY mini splits still leave the hardest parts up to you — pressure testing, vacuuming the system, handling refrigerant, or finding your own tech, and even dealing with bulky pre-charged line sets. GWIN™ HVAC changes all of that with Assisted DIY™. The GWIN Assisted DIY 21,000 BTU 22 SEER2 230V Two-Zone Ductless Mini-Split Complete System (18k condenser,9K + 12K Wall Mount) with 15 foot line set and communication wire with Assisted DIY™ is an evolution over DIY alone and makes GWIN™ a complete DIY mini split system that includes free expert tech support, with a tech included, so you never need special tools, never touch refrigerant, never run a vacuum pump, and never perform a pressure test. Our line sets with our easy connect flare-less fittings, allow for a professional operating system, with a professional look. Which also means no coiled mess and no guesswork — just a straightforward self-install ductless system that goes in like a true DIY HVACproject, backed by professionals every step of the way. Whether you're cooling or heating a garage, basement, bedroom, sunroom, home addition, tiny home, or cabin — GWIN™ HVAC is the ultimate DIY ductless solution with our Assisted DIY™ for homeowners who want to do it themselves, but done right." GWIN™ HVAC is the advanced version of DIY mini splits.

The Evolution of DIY Mini Splits
GWIN™ Assisted DIY™
Most DIY mini splits still leave the hardest parts up to you — pressure testing, vacuuming the system, handling refrigerant, or finding your own tech, and even dealing with bulky pre-charged line sets. GWIN™ HVAC changes all of that with Assisted DIY™. The GWIN Assisted DIY 25,000 BTU 22 SEER2 230V Two-Zone Ductless Mini-Split Complete System (24k condenser,7K + 18K Wall Mount) with 15 foot line set and communication wire with Assisted DIY™ is an evolution over DIY alone and makes GWIN™ a complete DIY mini split system that includes free expert tech support, with a tech included, so you never need special tools, never touch refrigerant, never run a vacuum pump, and never perform a pressure test. Our line sets with our easy connect flare-less fittings, allow for a professional operating system, with a professional look. Which also means no coiled mess and no guesswork — just a straightforward self-install ductless system that goes in like a true DIY HVACproject, backed by professionals every step of the way. Whether you're cooling or heating a garage, basement, bedroom, sunroom, home addition, tiny home, or cabin — GWIN™ HVAC is the ultimate DIY ductless solution with our Assisted DIY™ for homeowners who want to do it themselves, but done right." GWIN™ HVAC is the advanced version of DIY mini splits.

The Evolution of DIY Mini Splits
GWIN™ Assisted DIY™
Most DIY mini splits still leave the hardest parts up to you — pressure testing, vacuuming the system, handling refrigerant, or finding your own tech, and even dealing with bulky pre-charged line sets. GWIN™ HVAC changes all of that with Assisted DIY™. The GWIN Assisted DIY 42,000 BTU 22 SEER2 230V Two-Zone Ductless Mini-Split Complete System (42k condenser,18K + 24K Wall Mount) with 15 foot line set and communication wire with Assisted DIY™ is an evolution over DIY alone and makes GWIN™ a complete DIY mini split system that includes free expert tech support, with a tech included, so you never need special tools, never touch refrigerant, never run a vacuum pump, and never perform a pressure test. Our line sets with our easy connect flare-less fittings, allow for a professional operating system, with a professional look. Which also means no coiled mess and no guesswork — just a straightforward self-install ductless system that goes in like a true DIY HVACproject, backed by professionals every step of the way. Whether you're cooling or heating a garage, basement, bedroom, sunroom, home addition, tiny home, or cabin — GWIN™ HVAC is the ultimate DIY ductless solution with our Assisted DIY™ for homeowners who want to do it themselves, but done right." GWIN™ HVAC is the advanced version of DIY mini splits.

This condenser pad will fit all of the GWIN Condensers available.
Why purchase an Condenser Pad?
1. Protects the unit from pest, insects and critters that may cause damage to the condenser.
2. Reduce vibration from the AC against this pad so it does not hit against the ground. If a condenser is not placed on a support system like a pad, you risk damage being done each time the condenser vibrates against the ground.
Pros
- Unaffected by UV or weather
- Uniform rubbing transfers load evenly
- Lightweight, yet incredibly rugged
Material Type: Polypropylene
