Arizona's
Mini Split
Specialists.
We only do mini splits. That's the whole point.
While most HVAC companies treat mini splits as a side job, we built our entire business around them. Deeper knowledge. Cleaner installs. A lifetime warranty on our work.

We Only Do
Mini Splits.
Most HVAC companies install mini splits as a side gig. We built our entire business around them. That means deeper product knowledge, faster installs, cleaner work, and techs who can handle any installation.
When something goes wrong — a bad flare, a refrigerant leak, a blower wheel that looks like a science experiment — you want the team that's fixed it a hundred times. Not the one Googling the error code in your driveway.
Factory-Certified, Not Just Licensed
Mitsubishi Diamond Contractor and Samsung HVAC Preferred Dealer Plus certifications mean hands-on factory training and verified installation standards. Not just a license number on a van.
We Know Every Refrigerant, Every Brand
R-410A, R-32, R-22 — done them all. Mitsubishi, Samsung, Daikin, LG, Gree — we know the quirks of each system and how to install them right the first time. No surprises.
Full Lifecycle Service
We install it, certify it, clean it every year, and fix it if something goes sideways. One company, one relationship, for the life of your system. Pretty simple.
Statewide Arizona Coverage
Phoenix metro, Tucson, Flagstaff, Prescott, Yuma — if it's in Arizona and you need a mini split handled, we'll make the drive. Arizona is our backyard.
Where Would You Like Comfort?
Real installs from our customers across Arizona. Spoiler: mini splits go everywhere.

Garage / Man Caves / Home Gyms
'69 Camaro SS, hex lighting, a full gym setup — and a mini split keeping it all at 72°. This is what happens when you stop saying "it's too hot out there" and call Mini Split Guys.
Bedroom Comfort
Samsung Wind Free systems were made for bedrooms. Blast cold air to cool the room fast, then switch to Wind Free mode — no direct airflow, just a silent cloud of cool. The best sleep of your life starts here.
Installed with Pride
One look at our white glove installations by trained professionals reveals work done with pride. Done right the first time.
RV Garages & Hangars
Big space, big heat load — no problem. We size and install mini splits for RV garages, aircraft hangars, and oversized shops.
She Sheds & Studios
Your backyard retreat shouldn't feel like a sauna. A Samsung 12k Wind Free single-zone mini split turns any she shed, art studio, or garden office into a space you'll actually want to be in. Year-round. This is a 12'x16' Tuff Shed.

Old Heat Pump Blues?
Empty nester running a whole-home system to cool one room at night? A 1-ton in the master and a 2-ton in the core covers daily life — fire up the big unit when the kids visit. Keep $10k and stay comfortable. Watch your APS bill go down and have more comfort.
The new Samsung 360 was made specifically for commercial installations.
Commercial Installations
The same benefits that make mini splits great for homes? They're even better for businesses. Lower bills, smarter zoning, and a solar option that actually makes sense.
- —Zoning: Only cool the offices that are actually occupied. Revolutionary concept, we know. Each zone runs independently — no more freezing the whole building because one person is hot.
- —Demand Reductions: Smaller systems vs. one giant central unit cuts your demand charges significantly.
- —SolMini Solar: Most businesses run during the day — perfect for solar. You make the power, you use it, you profit.
Why Mini Split Guys
Mini Splits Are Not
a Sideline for Us.
As a licensed HVAC contractor with over 50 years of experience, we've seen firsthand the superior comfort, efficiency, quiet operation, and energy savings mini splits provide over traditional ducted systems. Our installations reflect the pride and craftsmanship behind every white-glove installation we perform.
The Flare Connection: Where Most Installs Fail
Every mini split has four flare connections joining the outdoor unit to the indoor unit — refrigerant lines operating at pressures exceeding 400 PSI. A leak from any one of them means lost performance, lost comfort, and permanent compressor damage.
The flare on the left was done by the factory — and is what most mini split installing companies use. Notice the angled flared surface is not smooth and is prone to freon leaks.
The flare on the right was properly fabricated on-site by our trained install crew using precision tools and is guaranteed not to leak for 5 years...or the recharge is on us!
Which one is most likely to leak?
Our custom on-site flaring process ensures optimal sealing surfaces and precise torque values — dramatically reducing the risk of refrigerant loss. It's one of the primary reasons we confidently offer a lifetime, no-cost installation warranty that is unmatched in the HVAC industry.
"Proper installation is not optional — it is the foundation of system longevity, continued performance, and uninterrupted comfort. This is why you choose Mini Split Guys."
Don't Take Our Word for It
"My shop was miserable and I dreaded going out there. I would put off things I needed to accomplish but couldn't take the heat. I was contacted by the owner who is a very nice guy with huge experience base... Today it was 107 degrees outside and my master bedroom easily got to 69 degrees! These guys are the best of the best! Highly recommend the Mini Split Guys!!!!"
"I like this one so much I'm having them install another one for my office!"

These guys are great! It's hard to find anyone that services or installs mini splits that isn't just doing it as an afterthought. Mini splits are this company's specialty and they service the units they install so you have peace of mind. Their customer service is also top tier: Super helpful, polite, and really put thought into what is going to be easiest/best for the customer in terms of placement and installation. Everything looked immaculate when they were done, honestly even cleaner than when they got here! We will definitely use their services again.

Brad was awesome. I got several quotes that were close to double what Mini Split Guys charged me. From the time I called them to the time I was enjoying cool air in my studio, it was two days. Incredible. Highly recommend.

If you are looking for an HVAC team that masterfully combines old-school customer service with cutting-edge technical expertise, look no further than Mini Split Guys. From the very first phone call, the experience was absolutely top-notch. It is rare to find a company that is as genuinely friendly as they are hyper-efficient, but they managed to strike that perfect balance right out of the gate. We have now used them for two separate projects in our new backyard ADU, and both installs were flawless from start to finish. What truly sets this team apart is their ability to think on their feet. Their problem-solving skills saved us a lot of headaches, and both systems are running perfectly. I highly recommend them to anyone looking for a seamless, professional, and stress-free installation!

We had a great experience with our recent mini split installation. They were very responsive from the start and came out quickly to assess the room and provide an estimate. Pricing was very reasonable, and the installation process was smooth and efficient. The team was professional, did excellent work, cleaned up thoroughly, and even followed up afterward. They also took the time to walk us through how to use the system, which we really appreciated. The unit is so quiet and cools the room so fast! Highly recommend!
