Residential Cooling
Ductless Mini-Split Installation
Finished attic that bakes all summer. A sunroom the furnace never reaches. A North Jersey colonial with radiators and no ducts at all. Mini-splits solve the rooms that central systems can’t touch — no ductwork, no major construction, heating and cooling in one quiet unit.

J&M installs Mitsubishi, Fujitsu, and Daikin systems — and we’re Mitsubishi City Multi certified, the credential behind their multi-zone technology. That matters because mini-split performance lives and dies on line-set work, placement, and commissioning done to manufacturer spec.

- Additions, sunrooms, garages, and finished attics or basements
- Replacing expensive electric baseboard heat

FAQ
Mini-Split Installation — common questions
Don’t see your question? Call 862-703-4222 — a real person answers, 24/7/365.
Do mini-splits work for heating in winter?
Yes — modern cold-climate models heat efficiently well below zero degrees, and many of our customers run them as primary heat for the rooms they serve. The key is specifying a true cold-climate unit, which is part of our design work, not an upsell.
How many indoor units do I need?
One per zone you want to control independently — which is not necessarily one per room. Open floor plans often share a unit; a multi-zone system can run several indoor heads off one outdoor unit. We design from how you actually live in the space, and we’ll tell you when fewer zones will do the job.
How long does installation take?
A single-zone system is typically installed in a day. Multi-zone systems usually run two, depending on line-set routing. Either way there’s no ductwork construction — it’s one of the least disruptive HVAC projects there is.
Are mini-splits noisy?
The opposite — indoor heads run at a whisper, quieter than most refrigerators, and the compressor lives outside. If your reference point is a window unit, the difference is night and day.
