How a ductless system works
Most air conditioners hang out of a window or come through a wall. A ductless system is different: an outdoor compressor sends refrigerant through a slim line set to a quiet indoor unit mounted high on the wall, which cools, and on heat-pump models heats, the room directly.
No ductwork, no blocked windows, and only a small opening in the wall. It’s an extremely efficient way to cool a home or business, and we install and maintain state-of-the-art systems for a wide range of customers.
Why ductless
Made for the way Westchester homes were built
Many homes here are heated by boilers and radiators and were never built for central air. Ductless gives you modern comfort without opening up your walls and ceilings.
No ductwork needed
Perfect for homes with steam or hot-water heat, plaster walls or no attic space for ducts.
Room-by-room control
Each indoor unit has its own setting. Cool the bedrooms at night without chilling the whole house.
Very high efficiency
No duct losses and variable-speed compressors make ductless among the most efficient systems available.
Heats, too
Heat-pump models can take the chill off in spring and fall, and supplement your boiler in winter.
Quiet
The compressor lives outside. Indoors you’ll hardly hear it. No more rattling window units.
Homes & businesses
Additions, sunrooms, finished attics and basements, home offices, shops and offices.
A new standard for efficiency
What SEER means for your electric bill
Air conditioner efficiency is measured by the Seasonal Energy Efficiency Ratio (SEER): how much cooling a system delivers for each unit of electricity over a whole season. The higher the SEER, the less the system costs to run.
Ductless systems are among the highest-rated air conditioners on the market. When we quote, we’ll show you the ratings of the options we recommend, and what the difference means in plain dollars.
Ask about rebates. Utility and New York State programs have offered incentives for qualifying heat pumps. We’ll point you to what’s current. See Con Edison rebates (opens in a new tab).
How it goes
Home visit
We look at the rooms, the walls and where the outdoor unit can go.
Right-sized plan
Which rooms, how many indoor units, and the right capacity for each.
Clean install
Line sets run through a small opening and are neatly covered.
Walk-through
We start it up, test it and show you how to use and care for it.
Keep it running like new
Ductless systems need care, too
Indoor filters should be cleaned regularly, and coils, drains and condensate pumps need professional cleaning to keep efficiency up and prevent leaks and odors. We also do blower wheel cleanings: the indoor unit’s fan wheel slowly collects dust and mold, which weakens airflow and causes musty smells, and a deep cleaning clears it out. Our technicians will show you the simple parts you can do yourself.
Service tech Winston was awesome, answered all my questions and explained everything perfectly. He even showed me how to clean the waste pump!

Ductless FAQ
Ductless questions, answered
Brands we work with include Mitsubishi Electric (opens in a new tab). Ask us what fits your home.
Is a ductless system a good fit for a house with radiators?
Often it's the best fit. Many Westchester homes are heated by boilers and radiators and have no ductwork for central air. A ductless system needs only a small opening for the refrigerant line, so there's no tearing open walls and ceilings.
Can a ductless mini-split heat as well as cool?
Heat-pump models do both. Depending on your home, a ductless heat pump can supplement your boiler in spring and fall or heat individual rooms. We'll help you decide what makes sense.
What does SEER mean?
SEER, the Seasonal Energy Efficiency Ratio, measures how much cooling a system delivers for the electricity it uses over a season. The higher the number, the less it costs to run. Ductless systems are among the most efficient air conditioners available.
Are there rebates for ductless heat pumps?
Utility and New York State programs have offered incentives for qualifying heat pumps. Eligibility and amounts change, so ask us when you request a quote and see Con Edison's rebate page (opens in a new tab).
