Mini-Split Installs by Our Own Crew
Every mini-split we put in is installed by our own technicians. We don't hand the job to subcontractors, and nobody on our crew earns a commission for selling you more equipment than the room needs. The recommendation stays about your house.
We install Samsung mini-splits supplied through Lennox. We're EPA 608 Universal certified for the refrigerant work a mini-split requires, and we're licensed, bonded, and insured on every job. We check your electrical panel during the estimate so nothing catches you off guard on install day, and we pull permits wherever the local jurisdiction requires them.
Estimates are free. If you'd rather spread out the cost, financing is available through Wisetack, subject to approval.
When a Mini-Split Makes Sense
A mini-split has two main parts. An outdoor unit sits outside, and an indoor unit sits in the room it serves. A line set, the copper refrigerant lines and wiring that connect the two, runs through a small opening in the wall, so there's no ductwork to build. The system runs as a heat pump, so the same equipment cools in summer and heats in winter. With Upstate summers sitting in the 90s and winter nights dropping near freezing, that two-season job fits the way homes here are used.
A mini-split can also work alongside your central system. The main system keeps handling the house, and the mini-split takes care of the one space it never reached well. If your home already has good ductwork throughout and you need a whole-house system, a ducted heat pump installation may be the better fit, and we can walk you through both.
- A bonus room or room over the garage that's always hotter than the rest of the house
- A garage or workshop you want to use year-round
- An addition or sunroom where running new ducts would be hard
- An older home that was built without ductwork
- One room that never matches the thermostat in the hallway
- Window units you're ready to get rid of
Choosing Where the Units Go
Where the equipment sits has a lot to do with how comfortable the room feels.
Inside, the indoor unit needs a spot where its air can spread across the room. Open areas are easier to cover than rooms broken up by walls and doorways. Furniture, curtains, and tall shelving in front of the unit block airflow. Cool air sinks and warm air rises, so placement also decides which part of the room feels the difference first.
The line set needs a route from the indoor unit to the outdoor unit. Running it through a closet, attic, or crawlspace can keep it out of sight and cut down on wall repair. We look at those options before anything gets drilled.
Outside, the outdoor unit needs open air around it and room to be serviced. It shouldn't sit tight against shrubs or a fence. It also shouldn't sit right under a roof edge where rain pours off, or next to a door or walkway. In heating mode the unit drains water as it defrosts, and in a cold snap that water can freeze where people walk.
We'll go over the placement with you before install day so you know exactly where everything will go and why.
Sizing a Mini-Split for Your Space
A mini-split should be sized from a load calculation, not a guess based on square footage. We measure the space on site and look at what actually drives heat into it:
Getting the size right matters both ways. A unit that's too big cools the air quickly and shuts off before it pulls much moisture out, which can leave a room cool but clammy in a humid Upstate summer. A unit that's too small runs nonstop on the hottest afternoons and coldest mornings and still can't keep up.
- How big the room is and how high the ceiling goes
- How many windows it has and which way they face
- How well the walls and ceiling are insulated
- How the room gets used, such as a garage door that opens often or a home office full of electronics
Mini-Split Kits vs. Professional Installation
You've probably seen boxed mini-split kits at home stores, and some come with pre-charged lines. They can make the job look simple. The parts that decide how well a mini-split works aren't in the box, though.
A unit that sits out of level or drains poorly can start leaking water indoors. A slow refrigerant leak at a connection shows up later as a system that can't keep up. Problems like these can trace back to how the system went in.
With a professional install, those details are handled from the start. We size the system for the room, check the electrical, set the drain, clear air and moisture out of the lines, check the refrigerant charge, and test heating and cooling before we leave.
- The right size for the room, based on a real load calculation
- An indoor unit mounted level, with a drain line that slopes the right way so water doesn't back up into the room
- Proper electrical service for the outdoor unit
- Refrigerant connections that stay sealed for years, not just on day one
What Affects Mini-Split Installation Cost
The cost of a mini-split depends on your house and the space you want to cover. The main things that move the price are:
Your estimate is free, and we'll go over what's included before any work starts. Financing is available through Wisetack, subject to approval.
- System size — a larger space needs more capacity
- The amount of space you want covered — one room is a different job than several
- Distance between units — a longer line set route takes more material and labor
- Your walls and access — brick, finished basements, and tight attics can change how the line set gets run
- Electrical work — some homes have panel space ready, and some need more work to support a new system
- Where the outdoor unit goes — the surface it sits on and how easy the spot is to reach both play a part
How a Mini-Split Installation Works
Already have a ductless system that's acting up? We also handle ductless mini-split repair.
- 1Visit and measure. We look at the room, measure it, and check your electrical panel.
- 2Plan the placement. We pick the spot for the indoor unit, the line set route, and the outdoor unit location, and go over it with you.
- 3Install the system. We mount the units, run the line set and drain, and connect power. Shoe covers and drop cloths protect your floors while we work.
- 4Start up and test. We pull the air and moisture out of the lines with a vacuum pump, check the refrigerant charge, and test the system in both cooling and heating.
- 5Show you how it works. We go over the remote and settings, then clean up before we leave.

Sonja BlackGoogle review · July 2026Read Sonja Black's review on GoogleOur house HVAC system not been serviced in too long of time I'm embarrassed to say. Rhino HVAC was friendly, informative and prompt with sending a tech to our house for service. Our tech James went through the whole system thoroughly, patiently and was completely knowledgeable. And he did it with a sincere and friendly customer service attitude. He showed us a few mandatory points of how we can keep things in good condition in between services such as timing of replacing filters, keeping the condensers clear enough from our garden growth and more. He also pointed out the 100% need for a kill switch to our unit in the attic to prevent any flooding damage that would occur if our unit had a water issue-A small cost to prevent a major one! We have "found" our HVAC go to. I highly recommend Rhino HVAC.

Gary MurrayGoogle review · June 2026Read Gary Murray's review on GoogleRhino HVAC came highly recommended in a local FB group, by numerous members. When I first called no one answered, and I have anxiety so I just hung up without leaving a message and continued being stressed out…🤷♀️😵💫 I received a call back from Ronnie fifteen minutes later and as he was in the area, was at my house and diagnosing the issue within twenty minutes. I don’t think you can get a quicker response time than that! As a less than experienced homeowner with this kind of stuff, and a solo female, I felt very comfortable with Ronnie in my home, very respectful, cleanly and well presenting-no creepy vibes at all-which is a concern of mine from previous experiences. He was clear about delivering the information he gave me about what he was going to do initially, and after assessing, clearly communicated what the issue was and a clear quote to fix it. Ronnie continued to be on top of things ordering the part as soon as I gave the go ahead for the job, picking the part up as soon as it was available and on his way to my house as soon as he got it. I felt like a priority with the all consistent communication. After Ronnie fixed my AC(yay!!!)…he also took the time to go under my crawl space and let me know about a potential fire hazard with how my unit was apparently setup before I purchased the home, and gave me a reliable referral to a local electrician who could help with that. Ronnie really went the extra mile with great service and results and I will definitely use Rhino HVAC in the future should I need to. Thanks again, Ronnie for your time and effort!❄️🥶

Frequently Asked Questions
Can a mini-split heat and cool?
Yes. A ductless mini-split is a heat pump, so it cools in summer and heats in winter with the same equipment. Upstate winters are mild enough that a mini-split can handle most of the heating season for the space it serves.
Do I need ductwork for a mini-split?
No. A mini-split sends refrigerant through a small line set to an indoor unit in the room. That's what makes it a good choice for additions, garages, and older homes without ducts.
Can a mini-split go in a garage?
Yes, a garage is a good fit for a mini-split. Insulation and how often the big door opens make a real difference, so we factor both into the sizing.
What brand of mini-split do you install?
We install Samsung mini-splits supplied through Lennox.
Do I need a permit to install a mini-split?
Many local jurisdictions require one for new heating and cooling equipment. We pull permits wherever they're required, so you don't have to handle it yourself.
Can I finance a mini-split installation?
Yes. Financing is available through Wisetack, subject to approval, and we'll explain the options when we go over your estimate.
