Air Conditioning Maintenance Tips for Ductless Mini-Split and Central AC Units
Ductless Mini-Split vs Central AC: Which Is Right for Your Home?
It’s natural for you to sweat bullets in July and think, “Should I get a Central AC or just slap a few mini-splits on the walls?” Classic homeowner dilemma. Both options will chill your place, but they’re totally different beasts—money, installation headaches, looks, the whole nine yards. Let’s get real about air conditioning maintenance in Michigan and what you’re signing up for.
What’s the Deal with Central AC?
Imagine a giant, humming machine in your basement (or wherever) that pumps cold air through a bunch of hidden tubes—aka ducts—snaked all over your house. The warm air goes in, the cold air comes out, and boom, your whole place feels like a refrigerated grocery aisle. But, performing indoor air quality assessment is a must. If your house already has ductwork, it’s honestly pretty painless. Big houses? This thing’s built for you.
Ductless Mini-Splits—What Are Those?
These are like the rebels of the AC world. You get a box outside (the compressor) and then some sleekish units mounted high up on your walls or ceilings inside. No ducts, no tearing up your house. Each unit cools just the space it’s in. Super handy for old houses, awkward add-ons, or when you just want grandma’s room to feel like Antarctica but keep the rest of the house normal. Yes, you ought to keep the ductless mini-split installation, repairs or maintenance in mind.

How to Compare Mini-Split with Central AC
Installation
•Central AC: Hope you like construction dust, because if you don’t already have ducts, you’re getting them. Not cheap, not quick.
•Mini-Split: Poke a hole, run some lines, mount the unit, done. Way less mess. Perfect for weirdly shaped or ancient homes.
Cost
•Central AC: The system itself might be a bargain, but adding ducts? Oof. That’s where your wallet cries.
•Mini-Split: Each unit costs more, especially if you need a bunch. But if you don’t need to freeze the whole house, you could save cash.
Energy Efficiency
•Central AC: Ducts leak. Up to 30% of your nice cold air could just disappear. Not great.
•Mini-Split: No ducts, no leaks. Plus, you only cool the rooms you care about. Superefficient.
Aesthetics
•Central AC: The only thing you see are those little vents. Very “out of sight, out of mind.”
•Mini-Split: Units on your walls or ceiling. Some people hate the look. Some people don’t care. Your call.
Comfort & Control
•Central AC: Set the temp once and your whole house obeys. Simple, but not super flexible.
•Mini-Split: Zone control, baby. Grandma can have her igloo, you can stay toasty. More control = happier people.
Maintenance
•Central AC: Gotta stay on top of duct cleaning and filters, or you’ll get a nose full of dust bunnies.
•Mini-Split: Filters are right there, easy to clean. But yeah, every indoor unit needs its own TLC.
What’s the Move?
•Go Central AC if: You’ve already got ducts, want that invisible whole-home cool, hate seeing gadgets stuck to your walls.
•Try Mini-Splits if: Your place has zero ductwork, you built an addition, want laser-focused cooling, or just like geeking out over zone controls.
Both of these systems have their fan clubs. If you want your AC hidden and your house already has ducts, central is probably the easiest. On the other hand, if you’re ductless, want to save on the power bill, or just like the idea of customizing each room’s climate, mini-splits are pretty slick. Honestly, it’s all about what fits your house and your vibe. Don’t let some pushy contractor command you on air conditioning maintenance.
