Mini Split for a Tiny Home
Tiny homes present a unique physical challenge for heat management along the I-35 corridor. You are balancing small floor space against high sun exposure from large accent windows and metal roofing.
Living in a compact footprint from Waco down through Austin and New Braunfels means dealing with relentless Central Texas heat. The total volume of air inside a tiny house is low, but heat builds up quickly when afternoon temperatures push past 100 degrees.
Standard central cooling units do not fit these structures, and window units are loud, block natural sunlight, and drain power without controlling humidity. A ductless mini split unit provides a clean path to quiet, continuous cooling without eating into your wall space.
Mounting cooling equipment in a compact space requires a practical plan. The airflow path, loft clearance, and overall equipment size must work together so the space stays dry and cold from the floorboards up to the highest point in your sleeping loft.
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.

Heat rises fast in a narrow, high ceiling space. While your main living area or kitchen stays comfortable, the temperature in a sleeping loft can sit much higher. An indoor head must be placed high enough on the wall to pull hot air off the ceiling without blowing direct air right against your mattress.
We measure ceiling slope, rafter clearance, and bed placement before picking an installation spot. Directing the louvers downward during hot hours circulates cold air across the main floor, while setting the vanes horizontally keeps the loft usable when it is time to sleep.
- Angling air louvers down to move cold air across lower floors
- Positioning wall heads to pull trapped heat off ceiling peaks
- Maintaining proper clearance above mattress and loft railings
Why Oversizing Equipment Destroys Comfort
It is tempting to put a high output cooling unit inside a tiny home to combat severe Texas heat. Oversizing a system causes short cycling. The compressor turns on, drops the air temperature in a few minutes, and shuts off before it can pull humidity out of the structure.
As a general rule of thumb, small builds require conservative BTU matching based on insulation levels, window square footage, and sun orientation, which a site visit confirms. Matching the lower end of variable speed compressor output allows the system to run long, steady cycles that strip moisture from the air.
Single Head Coverage Strategy
Most tiny house floor plans perform best with a single indoor head unit when interior airflow paths remain open. Running one head saves interior wall space and keeps electrical demand low on your main service panel.
Air needs an unobstructed line of sight to travel from the main living zone into bathrooms or storage nooks. Open framing, open loft staircases, and simple wall transfer grilles let air cycle back to the head unit without creating stubborn hot spots.
Managing Solar Heat Gain From Glass
Tiny homes often use large picture windows or glass doors to make small rooms feel open. In Central Texas, glass panels work like radiant heaters on sunny afternoons. Direct sunlight pouring through glass forces your cooling system to work continuously against incoming thermal energy.
Placing the outdoor condenser in a shaded spot away from direct sun helps the unit run smoothly when outdoor temperatures rise past 110 degrees on bad afternoons. Running clean line sets along exterior trim lines protects refrigerant pipes while keeping the building profile neat.
Questions People Ask
Can one mini split head cool both the main floor and a sleeping loft?
Yes, if the indoor head is installed high on an exterior wall with proper louver adjustment. The fan pulls hot air off the loft ceiling while pushing cold air down to the main floor. Open loft railings and unobstructed airflow paths allow the air to cycle naturally without leaving hot air trapped above.
Where should the outdoor condenser unit be mounted on a tiny home?
The outdoor unit can mount directly to a reinforced trailer tongue, a dedicated exterior equipment rack, or a ground pad next to the home. Ground pads work well for stationary builds. For mobile setups, securing the unit to structural framing using vibration isolation pads keeps the connections tight during transit.
How much electrical power does a ductless unit pull in a small build?
Ductless systems use inverter compressors that adjust their speed to match cooling demand. Instead of pulling heavy current spikes like old equipment, they operate on low current once the space reaches your thermostat setpoint. This low power draw fits easily within common electrical setups used along the I-35 corridor.
Will a mini split maintain temperatures under an uninsulated metal roof?
Metal roofs generate heavy heat load on summer afternoons. A mini split works continuously to pull heat out, but performance depends on the structure having baseline insulation. During a site visit, inspecting the ceiling cavity helps determine the proper equipment sizing for your specific roof construction.
How do you control humidity inside a tightly sealed tiny house?
Compact builds catch moisture from cooking, showers, and breathing very fast. Mini splits pull water out of the air continuously when operating on lower fan speeds. Running the system on automatic mode keeps the compressor active long enough to strip moisture without overcooling the living space.
Book the Job
Cooling a compact space along the I-35 corridor from Waco down to New Braunfels requires direct planning around sun exposure, loft geometry, and equipment sizing. Getting cold, dry air into every corner takes proper wall placement and solid mechanical work. Call or text our crew to talk through your tiny home project and set up a site visit.
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.
