HOW GWIN WORKS
Install It Yourself
Easy To Buy. Easy To Install. Convenient. Tech Included.
We Send The Tech
Verifies No Leaks. Commissions Your System. Gives Pro Assurance.
Worry Free Warranty
We back your install—and our tech’s work—with full support. Zero DIY risk.
Equivalent Price. Equivalent Installation. Smarter Choice.
The Difference Is... Everything.
Easy Connect Flareless Fittings
NO COILED UP PROBLEMATIC, UNSIGHTLY LINESETS.
EASY CUT TO LENGTH, JUST LIKE A PRO SETUP.
No Flare. No Braze. No Torque Wrench.
Pre-charged, coiled up linesets don’t just look bulky and unprofessional on the side of your home—they can trap oil, restrict proper flow, and starve the compressor, ultimately shortening its lifespan. GWIN does it right, and does it easy.
No Worry of Installation Problems
We don’t just help with your install — we stand behind it.
Every system includes a 1-year worry-free labor & refrigerant warranty, covering both your work and our technician’s final setup.
No HVAC experience? No problem.
You install it → we make sure it’s done right, guaranteed.
No HVAC knowledge needed!
Trusted by GWIN Techs
Real people. Real techs. Real savings. Don't take our word for it — here's what the GWIN community has to say.
They hired us, Swift Air, for one of there installations. It was easy to install and the product is high quality. We highly recommend them for your HVAC needs. Thank you for choosing Swift Air!
We recently completed a commissioned startup on a Gwin mini split system after the homeowner installed the unit themselves. As an HVAC contractor, I really appreciate that Gwin Manufacturing requires a commissioned startup by a licensed technician. This process allows us to thoroughly inspect the installation, verify everything is installed correctly, and ensure the system is operating exactly the way it should. After completing the startup, I was very impressed with how quiet and smooth the unit runs. It’s clear that Gwinn put a lot of thought into the design and quality of their equipment. Because of this experience, we’ll be adding Gwin mini split systems to our pricebook and offering them to our customers moving forward. Great product and a great process to help ensure long-term reliability.
I’ve been trying to set another one of these units ever since I’ve put a 18,000 Btu wall hanging model in. I’ve been in the hvac industry for over 20 years and I’ve never seen a mini split this easy to install. Personally I really like them and I would 10/10 recommend one to anyone!

DIY VS GWIN — SAME PRICE. NOT THE SAME RESULT.
You're probably comparing DIY systems right now…
They all look similar. They all claim savings. But here's what actually happens:
THE PROBLEM WITH DIY HVAC
- Most Techs Will Not Touch It After installing a DIY system, it's hard to find a qualified tech willing to service it. Often, you're left stranded when problems arise.
- Hidden Leaks Go Undetected Without a professional pressure test, refrigerant leaks go unnoticed for months — until your system fails completely.
- Your Warranty Vanishes Most DIY warranties are impossible to claim without professional documentation. You’re at risk if anything goes wrong.
- No Refrigerant Coverage If a leak occurs, refrigerant is lost, and the homeowner is responsible for repair, replacement, and service costs- if you can find tech to fix it.
GWIN "ASSISTED DIY" SOLVES THEM ALL
- GWIN Comes With a Tech A certified GWIN tech inspects, vacuums, and charges your system.
- Zero-Leak Certified Professional pressure test catches every leak before it becomes a problem. Verified and logged.
- Worry-Free Equipment Warranty Equipment receives a full 10 yr parts and compressor warranty. Transferable. No fine print.
- Worry-Free Labor & Refrigerant Warranty Our 1 Year Labor and Refrigerant Warranty covers your installation work, or whoever installs it. If there is an issue with the system after installation, we will send a tech out.
HERE'S THE TRUTH:
You're paying about the same price either way.
So the real question is…
Why would you choose less?
Don't Pay over $12,000 For HVAC
Same comfort. Same professional result. Thousands less.
WHAT HOMEOWNERS SAY
Check our Google reviews, BBB rating, and customer install stories — they all point to the same thing: QUALITY.
"I am impressed with how much follow-up GWIN does on it sales to installation of the unit. The sales team were very good at the time of the sale. The unit was very well received no issues with it at time of delivery. It was very easy to install. And the contractor was great to work with that came out and checked the unit and charged it. Then they did a follow up to make sure I had no issues or problems with any thing . Great job"
"I recently purchased a new GWIN 24,000 BTU mini split system to replace a ten year old LG unit. It has been in service for about six weeks and is performing flawlessly. The LG was definitely older technology and never provided much heat in colder temperatures. This new GWIN unit really cranks out the heat. I live in Kentucky and have cold winters and hot summers. I've just had two weeks of below freezing temperatures, as low as -4 degrees f, and was very impressed with how well it heated. The unit is quiet, moves a lot of air and looks good. I read that it will handle wide voltage fluctuations that cause problems with other systems. Warranty sounds good. I hope I won't need it. I haven't tried the A/C yet, but I'm relatively confident that it should work well. All in all, I'm very pleased. Five Stars from me!"
"Great product. Fast shipping. I couldn’t be happier. The quality of the equipment is excellent, combined with the customer service and the warranty you couldn’t ask for more. If you want a Win, buy GWIN!"
"Excellent service, professional quality installation, and best of all, the customer service makes you feel right at home. I definitely recommend it, and the product is excellent, a great system, I would say one of the best."
"Had a great experience with them, equipment shipped same day , super fair pricing , highly recommend! They also followed up with me after installation! Great group!!"
"Jeremy was great he found me a one head unit that was big enough for the home I needed it in. Price is great. If you need help speak with Jeremy, he will help you Greatly."
