What has changed?
Tell us whether the unit is not heating or cooling as expected, cycling differently, leaking, making an unfamiliar sound or displaying a message. Note when the change began and whether it is constant or intermittent.
Brooklyn & Manhattan
Ductless mini-split installation and repair in Brooklyn and Manhattan, for room-by-room air conditioning and heating where conventional ductwork is not the right fit.

Existing ductless equipment
For a repair inquiry, start with what has changed. These details help explain the problem without asking you to diagnose it. For new equipment, see the installation planning checklist.
Tell us whether the unit is not heating or cooling as expected, cycling differently, leaking, making an unfamiliar sound or displaying a message. Note when the change began and whether it is constant or intermittent.
Say whether the issue affects one indoor unit or several. Include the make, model and any displayed code if available, plus earlier repair information you already have. You do not need to identify the failed part before requesting ductless service.
A focused system choice
Ductless systems pair an outdoor unit with one or more indoor units. The right approach depends on the rooms, existing heat, building requirements, available equipment locations, and a practical route for lines, power, and condensate.
Address rooms that run hot, cold, or need independent temperature control without assuming one layout fits every property.
Explore a system when new ductwork is impractical or when you want to keep an existing heating system in place.
Identify the rooms that need heating or cooling, then ask what calculation supports the proposed equipment capacity. ENERGY STAR’s sizing guidance explains why equipment that is too large or too small can struggle to keep a home comfortable.
Before choosing equipment
A useful project conversation starts with the property constraints. These details affect the equipment layout and the work required to install and maintain it.

Service context
Explore room-by-room comfort while accounting for occupied spaces, exterior equipment placement, and the route between indoor and outdoor units. For property-specific planning, see ductless mini-splits for Brooklyn brownstones.
Bring building or management requirements into the discussion early so equipment access, approvals, and installation routes can be considered. Our Manhattan co-op and condo HVAC page explains the building coordination involved.
Tell us who can provide access to the indoor and outdoor equipment and whether management needs to coordinate the visit. Share any access restrictions when requesting service.
For central system needs, see our central air conditioning service. For a broader starting point, visit air conditioning services.
We will use the details to start the right ductless service conversation.
