Mitsubishi Ductless Mini-Split Installation & Service in Palos Hills, IL
Your Authorized Mitsubishi Electric Diamond Contractor Serving Palos Hills,
Orland Park, Lemont & Beyond
Whether you’re heating a sunroom that your furnace can’t reach, cooling a bonus room above the garage, or looking to replace an old central system with something far more efficient — A-Guy Heating & Air’s Mitsubishi Electric ductless mini-split systems are built for exactly that. As a Mitsubishi Electric Diamond Contractor, we’re certified to install, service, and support the full Mitsubishi ductless lineup across the southwest suburbs.
Ductless systems work by mounting a compact indoor air handler directly in the space you want to condition, connected to an outdoor compressor unit via a small refrigerant line — no ductwork, no major renovation, no mess. You get precise zone control, whisper-quiet operation, and year-round comfort from a single system that both heats and cools.
Mitsubishi Ductless Systems A-Guy Installs & Services
We install and service the full Mitsubishi Electric ductless lineup, including:
- Single-zone wall-mounted systems — ideal for one room, a garage, a home office, or a room addition in Palos Hills area homes
- Multi-zone systems — one outdoor unit connects to 2–8 indoor air handlers, each controlled independently; perfect for whole-home zoning
- Ceiling cassette systems — flush-mounted ceiling units that distribute air in four directions, ideal for open-plan living areas and commercial spaces
- Horizontal-ducted air handlers — for spaces where some existing ductwork is preferred but full central ducting isn’t practical
- intelli-HEAT dual-fuel systems — Mitsubishi heat pump paired with a gas furnace for maximum cold-weather reliability (see our heating services page)
Common Reasons Palos Hills Homeowners Go Ductless
Many homes in Palos Hills, Palos Park, and Palos Heights were built before modern HVAC standards — and often have room additions, finished basements, or detached garages that simply weren’t designed with heating and cooling in mind.
A Mitsubishi ductless system solves this without the expense of running new ductwork:
- Room additions and enclosed porches that aren’t connected to the central system
- Finished attics, basements, and bonus rooms over garages
- Homes with radiators or radiant heat that have no existing ductwork
- Detached garages, workshops, and home gyms
- Hot/cold spots that the central system never resolves
- Replacing an old window AC unit with something quiet, efficient, and permanent
