Mini-Split Installs
Ductless mini-splits give you zone-by-zone comfort without tearing into walls for ductwork. Quiet, efficient, room-by-room.
Most homes have one or two rooms central HVAC just won't get right. The bedroom that's always 8° off. The garage you converted to an office. The sunroom that's a furnace in summer. Mini-splits fix those rooms — quiet, efficient, ductless, and installed by a credentialed pipefitter so the refrigerant lines don't leak in year three.
What's included

- ✓ Hot upstairs bedrooms — the one-thermostat-two-stories problem
- ✓ Additions and in-law suites
- ✓ Single-zone or multi-zone setups
- ✓ UA Local 101 journeyman pipefitter on every install
Rooms this makes sense in
Every home has a room or two the main system was never sized for. Here are the spaces this solves.
-
Sunroom
Glass walls turn three-season rooms into furnaces in summer and iceboxes in winter. A single mini-split head makes them year-round.
-
Garage / Workshop
Wrenching in 35° or 95° gets old fast. We install on a wall stud, vent through an exterior wall, and you're working in 70° year-round.
-
Finished Basement
Most basements are cold-floor / damp-air territory even in summer. A mini-split tied into the dehumidifier reflex fixes both at once.
-
Bedroom or Office
The one room that's always five degrees off the thermostat. Independent zoning means you can sleep cold without freezing the rest of the house.
-
Addition / In-Law Suite
Building onto the house? Don't oversize the central system. A dedicated mini-split keeps the addition comfortable and the utility bill sane.
Our process, step by step
No surprises, no upsells in the driveway. Here's exactly what happens from your first call to the day the job's done.
-
Free in-home consultation
We walk the space, ask how you actually use it, and answer the questions you didn't know to ask.
-
Heat-load calculation + sizing
We size off Manual J, not square footage alone. Right-sizing matters more than horsepower — oversized units short-cycle.
-
Unit + lineset selection
Mitsubishi, Daikin, LG, and others. We walk you through the trade-offs on price, efficiency, and how quiet each one runs.
-
Permits + scheduling
We pull the mechanical permit, coordinate with the village inspector, and book you for the next clean install window.
-
Install day
Typically 4–8 hours for single-zone, a day or two for multi-zone. Drop cloths down, shoes off, the dog stays inside.
-
Commissioning + leak test
We pull a vacuum, charge with refrigerant, run a leak test, and verify the temperature split before we call it done.
-
Walk-through + warranty registration
You learn the remote, we register the 12-year warranty in your name, and we leave a one-page cheat sheet on the kitchen counter.
Frequently asked
How quiet are mini-splits really?
Quieter than a standard refrigerator. The indoor head runs around 19-32 dB depending on fan speed — about as loud as a soft whisper at high. Most customers tell us they forget the unit is on, which is the highest praise we hear.
Will it heat AND cool?
Yes. Every modern mini-split is a heat pump, so the same unit cools in summer and heats in winter — down to roughly 5°F outside for standard models, lower for cold-climate models. For most rooms in southern Illinois, the standard unit handles the full year. If your space is hard to heat (like an unfinished room above a garage), we'll spec a cold-climate model with extended low-temp performance.
Can I install one in just one room?
Absolutely — that's the most common case. Single-zone setups (one outdoor + one indoor unit) are perfect for that bonus room that's always 8° off, the converted garage, or the sunroom that's a furnace in summer. We size, install, and walk you through operation in a single day.
How long does the install take?
A single-zone install is typically 4–8 hours, start to finish. Multi-zone systems run a day or two depending on lineset routing.
How much does a mini-split install cost?
Every install is quoted after a free in-home visit. A single-zone garage or sunroom install is the most affordable; a 4- or 5-zone whole-floor system costs more. You'll get an exact, written number before any work starts — no surprises.
Can I install one in my unfinished basement?
Yes — in fact, basements are one of the best use cases. Cold floors and damp air respond well to mini-splits because the indoor head also dehumidifies.
Do you handle the permits?
Yes. We pull the mechanical permit with your village, coordinate the inspection, and meet the inspector on-site. The permit fee is itemized on your quote.
Have a project in mind?
Free in-home consultation. We'll measure, plan, and quote in writing — no commitment.
