Ductless heating and cooling
Heat and cool any room without tearing the house apart
Ductless mini-split HVAC is the fix for the room that's never the right temperature: the addition the furnace never reached, the upstairs bedroom that bakes in July, the sunroom you close off in January. One indoor unit, one 3-inch hole, one day — and you get a Mitsubishi Hyper-Heat air source heat pump that heats at -13°F and cools with real humidity control.
Because every indoor unit has its own thermostat, you stop paying to condition rooms nobody is in. Bedrooms at 65°F, living room at 70°F, guest room off until the guests show up.
- Retire the window units that block the view and rattle all night
- Add modern comfort to a historic home without touching its exterior
- Each zone controllable from the wall, the remote, or the Mitsubishi Comfort App
Five reasons
Why homeowners choose ductless mini-split systems
Cheaper to run
Inverter compressors ramp to exactly the load. Up to 40% less to cool than window units, half the cost of baseboard heat.
Rebates & savingsCleaner air
Multi-stage washable filtration in every indoor unit. No ducts means no dust-filled ductwork to blow it around.
Wall-mounted unitsFast install
No ductwork, no demolition. Most single-zone installs finish in a day; the wall hole is three inches.
How installation worksNo combustion
Nothing burns, nothing vents, no carbon monoxide, no fuel truck. Runs on the electricity you already have.
Switching from oilRebate eligible
NYS Clean Heat and Efficiency Vermont both pay on qualifying ductless installs. We handle every form.

Zoned comfort
How zoning cuts the bill
A furnace has one setting for the whole house. A ductless system has one per room. Heat the rooms you use, when you use them, at the temperature you actually want — and let the rest idle. Homes with a mix of sunny and shaded rooms, a finished basement, or an upstairs that runs ten degrees warmer than downstairs see the biggest gains.
Financing: 18 months at 0% with equal monthly payments — many single-zone systems come in under $100 a month.
Questions homeowners ask us
What is a ductless mini-split, in plain terms?
An outdoor unit and one or more slim indoor units connected by a refrigerant line through a 3-inch hole in the wall. No ducts. Each indoor unit heats and cools its own room with its own thermostat. It is an air source heat pump — the same technology as our whole-home systems, just sized to a room or a few rooms.
How many rooms can one outdoor unit handle?
Up to eight indoor units on one Mitsubishi multi-zone outdoor unit. Most homes we do run two to five. You can also start with one zone now and add zones later if the outdoor unit is sized for it — tell us at the estimate and we'll plan the capacity in.
Is a mini-split cheaper to run than a window unit or baseboard?
Yes, by a wide margin. Mitsubishi ductless units run up to 40% cheaper to cool than a window air conditioner and cut heating cost roughly in half compared with electric baseboard, because they move heat instead of making it.
How loud are they?
Indoor wall units run as low as 19 dB on low fan — quieter than a library. You'll hear the air, not the machine. The outdoor unit is about the sound level of a normal conversation and it sits outside.
Can I put one in a bedroom, a sunroom, a garage, a cabin?
All four, routinely. Bedrooms and additions are the classic use. Floor-mounted units suit sunrooms and cabins with knee walls. Insulated garages and workshops take a single-zone wall unit. Seasonal camps on Lake George and Schroon Lake use them for both cooling and shoulder-season heat.
Do mini-splits qualify for rebates?
Yes. NYS Clean Heat pays per-unit rebates on qualifying cold-climate ductless systems in New York, and Efficiency Vermont pays a set amount per unit in Vermont. The whole-home tier requires decommissioning your fossil-fuel system; partial installs still qualify for the standard tier. We file it for you.
