Mini Split for a Nursery or Kids Room
The last bedroom on the duct run is the one that still feels warm when the rest of the house has cooled down. For a nursery or a kids room that is a problem every night of a long Texas summer.
The central system pushes air from a closet or attic unit through a maze of ducts. Every turn and every foot of run steals pressure. The rooms at the end get whatever is left. Close the door, add afternoon sun on a west wall, and that leftover air cannot keep up.
A small person sleeps in that room. They do not care that the thermostat in the hallway reads 74. They care that the air over the crib or the twin bed is still thick and warm. You end up either overcooling the whole house or leaving a kid in a room that never quite settles.
A mini split is a separate system for that one room. An indoor unit on the wall, a compressor outside, a line set through the wall. That room gets its own cooling, its own fan speed, and its own setpoint. The rest of the house stays on the central system or shuts down for the night.
The Price on the Card
That is materials and labor for a standard single zone mini split installation. One day every week is the Joker Day at $2,200. Which day it lands on changes week to week, and the current Joker Day is revealed on the home page.
A $400 materials deposit books the date. The balance is due on completion.

Ranch houses and two-story homes along the I-35 corridor often have one indoor unit and a long duct layout. The main living space may sit close to the air handler. The kids rooms sit over the garage, at the back of the house, or on the west side. Those rooms get the smallest vents and the longest run.
On a still afternoon when it is well over 100 degrees outside, the sun loads that west wall and the roof. On a bad afternoon it can be past 110 degrees in the sun. The supply air that finally arrives is already mixed and tired. A closed door makes it worse. The room runs warm even while the living room feels fine.
- Longer duct runs leave less air at the last register
- West sun and rooms over a garage add load leftover air cannot handle
- A closed bedroom door cuts off the return path
Quiet at night when they need to sleep
The noisy part of a mini split is the compressor, and that sits outside on a pad or on the wall. The indoor unit is a fan blowing across a coil. At night you set the fan on low. The sound inside the room is air moving across the grille, not a unit cycling hard in the attic and not a vent blasting leftover air.
You still hear something. That is honest. It is not silence. It is a steady low fan in the room instead of a hot still bedroom or a central system that kicks on hard and then dumps a blast of air. Placement matters for a light sleeper in a crib or a twin bed. We keep the airflow from blowing straight across the sleep space when the wall allows it.
One setpoint for one small person
The indoor unit has its own controller on the wall or a handheld remote. You set 68, 70, or 72 in the nursery and leave the hallway thermostat wherever the rest of the family wants it. You do not have to freeze the living room so the back bedroom can sleep. The two systems do not fight each other.
During the day a garage gym or the main living space can run its own temperature. At night the kids room holds the number you chose. Independent control is the reason to put a dedicated unit on a room the ducts never served well. One small person gets the setpoint that room actually needs.
Putting a wall unit in a small bedroom
The indoor unit mounts high on a wall that can reach outside with a short line set. Condensate drains to the outside or to a small pump if the layout needs it. We look at crib placement, dresser layout, and where a kid might climb. The unit needs clear space in front of it so the air can throw across the room without hitting a bunk or a changing table.
Sizing is a general rule of thumb based on room size, sun, ceiling height, and how tight the house is. A site visit confirms the load. We do not pick a capacity from a chart and hope. We stand in the room, feel the west wall when we can, look at the existing vent, and then choose the indoor unit that matches that bedroom.
What we look at on the wall and outside
We walk the room and the outside wall. We check where the line set can pass through, where the outdoor unit can sit without blocking a path, a gate, or a fence, and how condensate will leave. We talk about nap schedule and whether the bedroom door stays shut most of the day.
Then you decide if the layout works. If it does, we schedule the work. The only way to start that conversation is to call or text. We work the corridor from Waco down through Austin to New Braunfels.
Questions People Ask
Why is the kids room hotter than the rest of the house?
Air from the central unit loses pressure over a long duct run. The last rooms get the smallest share of supply. Add a closed door, west sun, or a bedroom over a garage and the leftover air cannot keep that space comfortable. The hallway thermostat never sees the kids room, so the system thinks the house is fine while that bedroom stays warm at night.
Will a mini split keep a light sleeper awake?
The compressor sits outside. Inside the room you hear the fan in the wall unit. At night the fan runs on low so the sound is steady air, not a blast. It is not silent. It is different from a hot still room and different from a central unit that kicks on hard in the attic. We talk about wall placement so the air does not blow straight across a crib or a pillow.
Can the nursery be a different temperature than the living room?
Yes. The indoor unit has its own controller. You pick a setpoint for that room alone. The rest of the house stays on the central thermostat. A nursery can sit at 70 while the living room sits at 76, or the central system can shut down overnight while the kids room keeps running. That split control is why a mini split belongs on a room the ducts never served well.
How do you know what size unit a kids bedroom needs?
We start with a general rule of thumb for a small bedroom, then a site visit confirms the real load. Sun on the wall, ceiling height, how closed the door stays, and how tight the room is all matter. We do not treat a chart as a promise. We stand in the room and match the indoor unit to that space.
Where does the outdoor unit go for a nursery?
On a pad or on wall brackets with a short line set back to the indoor unit. We look for a spot that does not block a gate, a sidewalk, or a play area. Condensate has to drain out. The visit is when we pick that location with you there, looking at the same wall the nursery uses.
Book the Job
If the back bedroom still feels warm when the rest of the house has settled, a dedicated mini split is a straightforward way to give that one room its own quiet cooling and its own setpoint. Call or text and tell us about the room. We will talk through the wall, the outside pad, and whether a unit fits that bedroom. We work the I-35 corridor from Waco through Austin to New Braunfels.
Call or text the crew at (512) 297-7493. Tell us the room, the size and whether it is insulated, and send a photo of the wall you want the head unit on. Standard days are $2,400, materials and labor. The weekly Joker Day is $2,200, and the home page shows which day it is this week. A $400 materials deposit holds the date and the balance is due when the job is finished.
