What Is a Ductless Mini-Split (a.k.a. mini split AC)?
A ductless mini-split is a compact heat pump system: one outdoor unit connects to one or more slim indoor air handlers with small refrigerant lines—no bulky ductwork required. You get quiet operation, precise zoning, and year-round comfort (cooling in summer, heating in winter). If you’ve searched for a “ductless air conditioner” or “mini split AC,” this is it.
Our Ductless Mini-Split Services
Design & Installation
We perform a right-sized load calculation, recommend single-zone or multi-zone layouts, and select the best indoor head type and placement. Our clean installs include line-set routing, condensate management, and weather-resistant mounting—ideal for Oakbrook Terrace’s snow and summer storms.
Great fits: master suites, attic/garage conversions, garden-level apartments, three-season rooms, server closets, small retail suites, and restaurants.
Repair: Fast, Honest Fixes
Strange noises, error codes, weak heating, or water drips? Our techs diagnose refrigerant, electrical, sensor, and drain issues quickly and fix only what’s needed. We stock common parts for Bryant and other top brands.
Replacement & System Upgrades
If your older unit struggles in extreme temps or needs frequent service, upgrading to an inverter, cold-climate model can add capacity, efficiency, and better dehumidification. We also replace failed wall heads, add zones, or convert a dated window unit to a sleek ductless head.
Maintenance & Tune-Ups
Annual service protects your investment: coil cleaning, blower wheel inspection, electrical and refrigerant checks, drain flush, firmware/controls review, and filter care coaching. Clean systems run quieter and cut energy costs.

FAQs
Is a Ductless System Right for the Chicago Suburbs?
Many residences here (especially condos along Butterfield Rd, townhomes, additions, sunrooms, basements, and home offices) either don’t have ducts or have rooms that are always too hot or cold. Mini-splits solve that with:
- Zoned comfort: heat/cool only the rooms you use.
- High efficiency: inverter technology sips electricity and lowers bills.
- Whisper-quiet: great for bedrooms, nurseries, and home offices.
- Flexible styles: wall-mounted, ceiling cassette, floor console, or short-run concealed ducted.
- Cold-climate options: Bryant® models keep heating performance strong even in Chicago-area winters.
Single-Zone vs Multi-Zone. What to Choose?
- Single-Zone: one room needs help (e.g., sunroom or finished basement).
- Multi-Zone: 2 – 8 rooms with independent thermostats. Perfect for households with different comfort preferences.
What are some different style options?
- Wall-Mounted: most affordable, fast to install.
- Ceiling Cassette: nearly invisible, ideal for open living areas.
- Floor Console: great where wall space is limited.
- Short-Run Ducted: hides the unit while serving 2–3 nearby rooms.
