Ductless Mini Split Installation in Southern Utah

Cool a garage, casita, addition, or that one room that never gets comfortable.

Intro

A ductless mini split is a compact system that cools and heats a space with no ductwork at all.
Cox Climate Control handles mini split installation across St. George and Southern Utah. It is the answer for spaces your central system cannot reach, or homes where running ducts is not practical.
We are Mitsubishi Diamond Dealers, which means top-tier equipment and factory-backed expertise on every install.
One space or the whole house, we will size it right and install it clean.

Where a Mini Split Works Best

Mini splits are the most versatile tool in our trade. Here is where they shine:

That last one comes up constantly in St. George. Instead of replacing a whole system for one struggling room, a single mini split head can solve it.

Need cooling for the whole house through ducts instead? That is a central AC installation, and we do those too.

How Ductless Mini Splits Work

Simple setup. One outdoor unit connects to one or more slim indoor heads mounted on the wall.
Refrigerant lines run between them through a small opening. No ducts anywhere.
Each indoor head cools or heats its own space with its own temperature control. The garage can be 72 while the rest of the house does its own thing.

Why Ductless Is a Smart Choice in the Desert

Ducts leak. Every foot of ductwork loses a little cooling before the air reaches the room. A mini split delivers the air right where you stand, so nothing gets wasted in the attic.
You also cool only the space you are using, instead of paying to condition the whole house for one occupied room.
They run quietly. They handle the desert heat well. And every mini split we install both cools and heats, so that garage or casita stays usable through the cooler months too.

One Room or the Whole Home

Single zone

one outdoor unit, one indoor head, one space. Perfect for a garage, casita, or hot room.

Multi zone

one outdoor unit running several indoor heads, each with its own control. This can cover several rooms or a whole home with no ductwork.

Not sure which fits? That is exactly what the free quote visit figures out.

Efficient Systems and the Brands We Install

Mini splits are among the most efficient ways to cool a space, because no cooling is lost through ductwork and the system conditions only the zone you choose.

We install Mitsubishi, and we are proud to be Mitsubishi Diamond Dealers. That status means advanced training and equipment we would put in our own homes.

We believe in selling high-quality systems, full stop. A well-installed Mitsubishi mini split is a set-it-and-forget-it machine.

What Does a Mini Split Cost to Install?

The price depends on three things: how many zones you need, the capacity the space requires, and the specifics of the install location.

A single-zone garage setup and a multi-zone whole-home system are very different projects, so we will not throw a vague number at you.

What we will do is come out, measure the space, and give you an exact written quote for free. No surprise fees, ever.
Financing is available through Wisetack, and if another company already quoted you, get a free second quote from us before you sign.

Great experience. Honest and will definitely use them again and refer them to everyone. Willing to do the repair rather than try and sell us a whole new unit.

I had an excellent experience with Cox Climate Control! Ethan was professional, knowledgeable, and quickly diagnosed a serious issue with my air conditioner that had been causing me a lot of trouble. He fixed it much faster than I expected, and everything has been working perfectly ever since. I truly appreciate the honest service, fast response, and high-quality work. I highly recommend Cox Climate Control to anyone looking for reliable HVAC service. Thank you, Ethan!

Ethan came out in an Emergency call at Night when our a/c quit workingThe temperature was 109. He examined the a/c and found 1 condenser finished and compressor broken. He said he had 2 portable a/c units he could bring so we would not have to move my ill husband and I to a hotel. He came back with the units and set them up. to cool down our house. This was completed after 12 midnight. He said he would check on us the next day. This all happened on a Saturday night. Ethan said they could come back on Monday to discuss a new a/c at our request. He did return with a quote that we thought was fair and we organized to install the next day Tuesday. If you are looking to replace your A/C you could not find a more competent, caring, reliable Company. We highly recommend Cox Climate Control.

We recently had to replace our entire AC system and after lots of research, we chose Cox. We are so glad we did! Devin was patient as we explored many different options, drafted a few quotes for us, and answered all of our many questions. The team that came out to do the install was great as well! We felt very confident using Cox for such a big project.

Our AC unit randomly stopped working on a Sunday. It was July, during monsoons and things were pretty dire. (The chocolate chips in my pantry even melted!) Devin with Cox Climate Control answered the call and we had cool air that evening! He showed up, gave a great quote and didn’t pressure us to upgrade our unit. I cannot recommend them enough!

Cox Climate went above and beyond to take care of us in the middle of July! Tough to get service when you need it most. I was impressed about their competitive pricing and quick response! It’s refreshing to see companies that still value customers and taking care of the ‘little guy.’

Cox Climate Control is the ONLY way to go!!!! My AC went out in the middle of the night, so I called first thing in the morning. They had a technician at my house that afternoon, and my AC was repaired the same day. From the very first phone call to the final invoice, their communication was outstanding. They kept me informed every step of the way, were professional, friendly, and made the whole process stress-free. On top of that, their pricing was very reasonable. It’s hard to find companies that provide this level of customer service these days, and I wouldn’t hesitate to recommend Cox Climate Control to anyone needing HVAC service.

Mini Split FAQs

A compact heating and cooling system with an outdoor unit and one or more indoor wall-mounted heads, connected by refrigerant lines. No ductwork needed, and each head controls its own space.
Yes, with a multi-zone system running several indoor heads from one outdoor unit. It works especially well in homes without ductwork or where adding ducts is not practical.
Yes, garages and shops are one of the most popular mini split installs we do. One head turns an unusable summer space into a comfortable one year round.
It depends on the zones, capacity, and space, so we quote each job individually. The in-home quote is free, the price is exact, and financing through Wisetack is available.
Yes, nothing is lost through leaky ductwork, and you cool only the zone you are using. That combination makes ductless one of the most efficient ways to condition a space.
Yes, every mini split we install handles both, so your garage, casita, or addition stays comfortable in winter too, not just summer.
Most installs are done in a day. We mount the head, set the outdoor unit, connect and charge the system, test it, and walk you through the controls before we leave.
