Mini-Split AC Installation in Houston, TX - Licensed Ductless Experts You Can Count On
Some rooms never cool down no matter how hard the central system runs. A garage office, a converted sunroom, a second-story bedroom that stays ten degrees warmer than the rest of the house. Ductwork does not reach every space, and adding it is not always practical. 75 Degree AC handles mini-split installation across Houston with licensed contractors who get the placement, sizing, and line routing right the first time.
Ductless Mini-Split Installation Backed by Years of Houston Experience
Mini-split installation is precision work. Where the indoor unit sits, how the line sets routes, and which outdoor condenser matches the layout all affect how well the system performs long-term. 75 Degree AC handles this work daily across Houston, from single-zone garage cooling to full multi-zone systems that replace central air entirely.
Our licensed contractors work with Mitsubishi, Daikin, Fujitsu, and other top ductless brands. We match the right unit to the room size, ceiling height, and sun exposure so the system runs efficiently without overshooting or falling short. Every quote includes equipment, labor, line sets, electrical, and permits with no add-ons after the price is set.
Every mini-split we install is charged, started, and verified cooling on site before the job closes. Permits are handled where required, and same-day scheduling is available for standard single-zone projects across Houston.

Site Visit & Zone Planning
We visit your home, measure the space, check insulation and sun exposure, and determine how many zones the system needs. Wall placement, line set routing, and outdoor unit location are all planned before the quote is written.
Brand Selection & Pricing
Based on the zone plan, we recommend the right brand and model for your space. The full installation price is presented upfront, covering the indoor unit, outdoor unit, line set, electrical, and any permits required.
Indoor Unit Placement
Our contractors mount the indoor head at the correct height and angle for even air distribution. Wall penetrations are drilled cleanly, and the unit is secured to the mounting plate with proper leveling and drainage pitch.
Line Set & Outdoor Unit Setup
The refrigerant line set is routed between the indoor and outdoor units, insulated, and sealed at every connection point. The outdoor condenser is placed on a level pad or wall bracket with proper clearance for airflow and future service access.
Charge, Test & Verify Cooling
Refrigerant is charged to the manufacturer's exact specs. We power on the system, test every mode, check airflow and temperature drop across the indoor unit, and confirm the remote and controls respond correctly. The job closes only when cold air is verified.

How a Ductless Mini-Split System Cools Your Space
A mini-split works by moving heat from inside your room to the outdoors. The indoor unit pulls warm air across an evaporator coil filled with cold refrigerant. That refrigerant absorbs the heat, changes from liquid to gas, and travels through a copper line set to the outdoor condenser. The compressor pressurizes the gas, and the condenser coil releases the heat outside. The refrigerant cools back down, returns to liquid form, and cycles back to the indoor unit to repeat the process.
Because there is no ductwork involved, all the cooled air goes directly into the room the indoor unit serves. Each zone runs independently, so you only cool the spaces you are using. Most modern mini-splits use inverter-driven compressors that adjust speed based on demand instead of cycling on and off. That means quieter operation, less energy waste, and more consistent temperatures throughout the day.

About Houston, TX
Houston, TX is home to thousands of older houses, bungalows, and mid-century builds that were never designed with central ductwork. Neighborhoods like The Heights, Garden Oaks, and Oak Forest are full of homes where adding traditional duct runs means tearing into walls and ceilings. A ductless mini-split gives these homes reliable cooling without the construction headache. Newer suburban areas like Katy, Pearland, and Sugar Land see a different need. Room additions, converted garages, and bonus rooms built after the original construction often sit outside the reach of the central system.
Houston’s sprawling footprint and year-round cooling demand make ductless systems a practical choice for homeowners who need targeted comfort. The cooling season stretches from March through November, and spaces without dedicated AC quickly become unusable. 75 Degree AC provides mini-split installation across the entire Houston metro, from inner-loop neighborhoods to the surrounding suburbs, with TACLA-licensed contractors available seven days a week.
Frequently Asked Questions FAQ's
Do You Need a Permit to Install a Mini-Split System in Texas?
Most Texas municipalities require a permit for mini-split installation because it involves electrical work and refrigerant handling. We pull the necessary permits and schedule inspections so the job meets all local code requirements before the system goes live.
What Is the Difference Between a Single-Zone and Multi-Zone Mini-Split?
A single-zone system pairs one indoor unit with one outdoor unit and cools one room. A multi-zone system connects multiple indoor units to a single outdoor condenser, allowing independent temperature control in several rooms without running separate outdoor units for each space.
Can a Mini-Split System Cool an Entire House Without Ductwork?
A multi-zone mini-split system can cool an entire home by placing individual indoor units in each room or area. Our team sizes the outdoor condenser and each indoor head to match the square footage and cooling load, giving you whole-home comfort without any ductwork.
How Long Does a Typical Mini-Split Installation Take in Houston?
A single-zone mini-split installation usually takes between four and six hours. Multi-zone systems with three or more indoor units may take a full day or extend into a second morning depending on line set routing and electrical work involved in the layout.
Is a Mini-Split More Efficient Than a Central AC System?
Mini-splits avoid the energy loss that happens inside ductwork, which can account for 20 to 30 percent of cooling output in older homes. The inverter compressor adjusts speed to match demand instead of cycling on and off, which keeps energy use lower during partial-load conditions.
What Brands of Mini-Split Systems Does 75 Degree AC Install?
We install systems from Mitsubishi, Daikin, Fujitsu, and other top manufacturers. We help match the right brand and model to your space, energy goals, and budget so the system performs well from the first day it runs.
