Cooling a two story house in Central Texas is a classic battle against physics. Heat naturally rises, leaving your upstairs bedrooms sweltering while your downstairs living area stays chilly. When you switch to a ductless mini split system, deciding how many indoor units, or heads, you need comes down to how your family uses each floor.
Cooling a two story house in Central Texas is a classic battle against physics. Heat naturally rises, leaving your upstairs bedrooms sweltering while your downstairs living area stays chilly. When you switch to a ductless mini split system, deciding how many indoor units, or heads, you need comes down to how your family uses each floor.
At Jester Climate, we help homeowners from Austin down to San Marcos and up to Waco map out their home zones without any confusing upsells. Here is a clear guide on how to evaluate your layout so every room in your castle stays at the perfect temperature.
In cities like Georgetown, Round Rock, and Austin, summer heat hits roofs hard and pushes warm air down into the second floor. A central HVAC system often struggles to balance both floors with a single thermostat. Ductless mini splits solve this by creating independent zones, but you must account for the heavy heat load upstairs.
For most two story homes, the upstairs requires more cooling capacity per square foot than the ground floor. If your upstairs consists of three separate bedrooms, installing an indoor head in each bedroom provides maximum comfort and privacy. However, if you rarely use one of the guest rooms, you might choose to place a single head in the main upstairs hallway to cool the upper floor efficiently while keeping costs down.
Downstairs layouts are often open concept, combining the kitchen, dining, and living rooms into one continuous space. In these areas, a single larger indoor head can often handle the entire lower level. If your main floor already has existing central air ductwork in excellent condition, sticking with central AC for the downstairs while adding targeted ductless heads upstairs can sometimes be the most practical choice.
We always want to be direct about your options. If your entire two story home already has working, efficient central ductwork, replacing the central unit may be cheaper than installing four or five individual mini split heads. Mini splits shine when you want precise room by room temperature control, when you are converting a garage or attic, or when your upper floor never gets cold enough with central air alone.
To determine your exact head count, start by counting the closed off spaces that need dedicated control. A typical setup for a two story home in Killeen or Temple might use one head downstairs in the main living area, one in the primary upstairs bedroom, and one or two additional heads for upstairs kids rooms or home offices. That creates a three or four zone system tuned to your actual daily routine.
Every indoor head functions as its own realm of comfort. Keep in mind that for budget conscious projects, you do not have to cover every square inch on day one. You can focus on the hottest upstairs bedrooms first, which instantly relieves the pressure on your main living spaces.
A single mini split head located in an upstairs hallway can help lower the overall temperature of the second floor, but it will not provide precise comfort in closed bedrooms. Airflow relies on open doors and circulation fans. If private sleeping spaces need exact temperatures, dedicated indoor heads in each bedroom are always the best choice.
Yes, buying a window unit or portable unit is initially much cheaper than installing a permanent ductless mini split. However, window units are louder, block your view, and are less efficient to run long term. A mini split is a permanent solution that operates quietly and mounts neatly on your wall.
We keep pricing simple with our flat rate structure. A standard single installation is a flat $2,400 for materials and labor combined. We also run a Joker Day once a week with a reduced rate revealed on our homepage. You book your install date with a $400 materials deposit, and you pay the remaining balance by card after the job is done and you see the system blowing cold air.
Permit requirements vary by city across Central Texas, from Waco down to San Marcos. The installer handles whatever permits are required by your local municipality, so you do not have to worry about navigating city code offices yourself.
