You know what’s tricky? Figuring out how to add modern air conditioning to a beautiful old building without ruining its character. I tackled this exact challenge a few years ago with a retail store project, and I’ve got to tell you – mini splits absolutely saved the day.
The Situation We Faced
Picture this: a gorgeous retail space in a building from the 1920s. We’re talking exposed brick walls, those amazing industrial-style open ceilings – real character stuff that you just don’t see in modern buildings. The catch? The old AC system was on its last legs (12 years old!), and all the ductwork had already been pulled out.


The store owner and landlord wanted options to install a new system but didn’t want something that would be overbearing nor cost a lot to install. They needed a new system with their build-out. That’s when I suggested something a little different from the usual approach. So I gave them several options but the best option ended up being the least expensive.
What We Did Instead
Instead of going the traditional route, we installed three one-to-one mini splits. Here’s what we used for those of you that are interested:
- Three 2-ton Daikin heat pump mini-splits
- Outdoor units: RX24WMVJU9
- Indoor units: FDMQ24RVJU
But here’s the cool part – we used exposed spiral ductwork with these units. I think it looks amazing with the industrial vibe of the space.




Why It Worked So Well
Let me tell you why this turned out to be such a win. First off, it was actually cheaper than installing traditional systems or RTUs with tons of ductwork. But that’s just the beginning.
These units are incredibly quiet. I mean, whisper-quiet. You can barely tell they’re running. And because we could zone the system properly, the air flows super evenly throughout the space. No more hot or cold spots!
Want to know the best part? These systems are absolute workhorses in commercial settings. I’ve been in this business for a while now, and I’ve seen firsthand how mini splits can outperform traditional systems, especially in older buildings.
The Hidden Perks Nobody Talks About
Here’s something most people don’t know – in commercial settings, these units often come with better warranties than traditional systems. The maintenance is simpler too. Plus, they break down less often, which means fewer repair bills. Who doesn’t love that?
The End Result
The store owner? Thrilled. And I get it – they got a system that:
- Looks great with their vintage-industrial vibe
- Runs super quietly
- Costs less to operate than traditional AC
- Was actually cheaper to install
- Didn’t require tearing up their beautiful old building
Should You Consider Mini Splits for Your Space?
Look, I’m not saying mini splits are perfect for every situation. But if you’ve got an older building, especially one with character you want to preserve, they’re definitely worth considering. They’re particularly great if:
- You’re dealing with a historic building
- You don’t have space for traditional ductwork
- You want to keep your energy bills down
- You need flexibility in how you heat and cool different areas
Real Talk
Here’s the bottom line – I’ve been doing this for a while now, and I’ve seen all kinds of HVAC solutions. What I love about mini splits, especially in commercial settings like this retail store, is how they solve multiple problems at once. You get the modern comfort you need while keeping the historic charm you want, and usually at a better price point.
