Mini Splits for Manhattan Offices
Zone control for conference rooms, server closets, open floor plans, and private offices. No ductwork required — ideal for Manhattan's pre-war and loft-style commercial spaces.
Zone Control
Every room gets its own thermostat. Conference rooms, server closets, and offices each run independently.
No Ductwork
Ductless systems require only a 3-inch wall penetration — no dropped ceilings or construction disruption.
Whisper Quiet
19–32 dB indoor operation — quieter than a whisper. Perfect for quiet professional environments.
Why Offices Choose Mini Splits
Manhattan offices have a universal complaint: someone is always too hot or too cold. Central systems heat and cool the entire floor the same way, regardless of whether the conference room has 12 people in it or the corner office has afternoon sun baking through the windows.
Mini splits solve this with individual zone control. Every room — or every zone in an open plan — gets its own thermostat and its own indoor unit. The conference room can be set to 68°F while the server closet runs at 64°F and the open workspace sits at 72°F. No more thermostat wars.
Common Office Zones
Open workspace
Wall-mounted or ceiling cassette for broad, even coverage across the main floor area.
Conference rooms
Dedicated zone for spaces with variable occupancy. A full conference room generates significant heat from bodies and electronics.
Private offices
Individual control for partners, executives, or anyone who needs their own comfort setting.
Server / IT closet
Dedicated cooling zone running 24/7 at a lower setpoint. Server rooms need consistent cooling even when the rest of the office is off.
Reception / waiting area
Front-of-house comfort for clients and visitors.
Not Sure How Many Zones Your Office Needs?
We'll assess your floor plan, occupancy patterns, server room heat load, and building constraints — then design a zone layout with a written estimate.

Best Indoor Units for Offices
Wall-Mounted Units
The most affordable and common option for offices. Mounted high on the wall, out of the way. Best for private offices and smaller open areas. Trade-off: visible on the wall, which matters in some professional environments.
Ceiling Cassettes (4-Way)
Recessed into a drop ceiling with only the grille visible. Distributes air evenly in four directions — excellent for conference rooms and open floor plans. Requires a drop ceiling with at least 10 inches of plenum space.
Slim Duct (Concealed)
Completely hidden above the ceiling. Air is delivered through small registers — the unit is invisible. Best for executive offices, law firms, and professional environments where aesthetics are a priority. Higher cost but zero visual impact.
The Server Room Problem
Server closets and IT rooms are one of the most common reasons offices add a mini split zone. These spaces generate heat 24/7 from networking equipment, servers, and UPS systems. They need dedicated, independent cooling that runs even when the rest of the office HVAC is off — nights, weekends, holidays.
A single-zone wall-mounted mini split dedicated to a server closet typically costs $3,500–$5,000 installed and can save thousands in equipment failure and downtime costs.
We size these based on the actual heat load of the equipment in the room, not just the square footage.

Office-Specific Considerations
Noise levels
Modern mini split indoor units operate at 19–32 dB, quieter than a whisper. This matters in quiet office environments. Ceiling cassettes tend to be slightly quieter than wall units.
After-hours cooling
Mini splits allow you to cool only occupied zones. If one person works late, they can run their zone without cooling the entire floor.
Building board approval
Co-op and condo boards often have rules about exterior condenser placement. We handle board applications and coordinate compliant installations.
Lease considerations
If you’re a tenant, understand who owns the HVAC equipment at lease end. We recommend clarifying this before installation.
Frequently Asked Questions
