The top-floor bedroom, the addition and the parlor floor

Every older New York house has one: a room that runs ten degrees off from the rest. A top-floor bedroom under the roof, a rear addition, a brownstone parlor with no space to run a duct. A window unit blocks the glass and rattles the sash. A ductless mini-split cools the room from one wall-mounted head and a thin line set, with no ductwork at all.

The same system works in reverse. In heat pump mode a mini-split warms the room in cold weather, so the head that cools a bedroom in July can take the edge off it in January.

Where the head goes and how the line set runs

Placement decides how a mini-split feels day to day. The head wants clear airflow across the room and distance from art, furniture and the spot where someone sleeps. On the framed-prints job in our gallery, the head sits high on the wall above a group of black and white prints, with air moving over the room rather than at the frames.

The line set, the refrigerant lines, drain and control wiring, runs to the outdoor unit as short and neat as the building allows, and the outdoor unit is set level on a pad or bracket. We test the system before we leave so you see it heat and cool.

Troubleshooting and upkeep

Ductless mini-split troubleshooting is part of what we do for existing systems, whoever installed them. The usual culprits are a clogged filter, a dirty coil, a drain line that has backed up and dripped onto the wall, and a unit throwing an error code that a diagnostic inspection can read.

Heat pump and mini-split maintenance keeps the system efficient, helps prevent seasonal breakdowns and extends its lifespan. A maintenance visit covers the filters, the coil and the drain, so the head is clean before the first hot week or the first cold one.

Where a mini-split fits next to the rest of the system

A mini-split often sits alongside a furnace or boiler rather than replacing it. See how we handle furnace and heat pump service on the heating side, and read heat pump vs central AC to see how a heat pump compares to a ducted system.
