Ductless Mini-Split in Katy, TX
Texas TDLR Licensed Air Conditioning & Refrigeration Contractor (#TACLB145586E) installing single-zone and multi-zone ductless mini-split systems for Katy homes. Ideal for additions, bonus rooms, garages converted to living space, and areas where extending ductwork is impractical. Proper sizing, City of Katy permitting, and efficient cooling and heating.
Ductless Mini-Splits Built for Katy Homes and Climate
Many Katy homes have rooms that the main central system does not serve well — room additions, bonus rooms over garages, home offices, sunrooms, or spaces where running new ductwork would be costly or disruptive. Ductless mini-splits deliver targeted cooling and heating with excellent humidity control, which matters in west Houston’s long cooling season.

How Ductless Mini-Split Installation Works in Katy
A clear process from the first home assessment through City of Katy inspection and system handover.
In-Home Assessment
We visit your Katy home, evaluate the spaces you want to condition, note wall and outdoor placement options, electrical capacity, and discuss single-zone versus multi-zone needs and budget.
Load Calculation & System Design
We size each zone properly and recommend the outdoor unit capacity and indoor head locations that deliver comfort without short-cycling or excessive runtime.
Permitting & Scheduling
We submit the City of Katy mechanical permit. Once equipment is ordered and the permit is in process, we schedule the installation on a date that works for your household.
Professional Installation
Licensed technicians mount the indoor units, set the outdoor condenser, run the line set and condensate drain, make electrical connections, evacuate and charge the system, and commission each zone. The work area is left clean.
Final Inspection & Walkthrough
We meet the City of Katy inspection and then walk you through remote or app controls, filter cleaning, and recommended maintenance so you get the full benefit of the new system.
Because we are based in nearby Cypress, most Katy ductless installations can be scheduled promptly and completed with minimal disruption to your routine.

Katy Ductless Mini-Split FAQ
Mini-splits are ideal for room additions, bonus rooms, converted garages, home offices, and any space where running new ductwork would be expensive, disruptive, or impractical. They also provide independent temperature control that a single central system cannot easily match.
Most single-zone installations are completed in one day. Multi-zone systems or more complex routing may take one to two days. We provide a clear schedule after the in-home assessment.
Yes. We submit the required mechanical permit and coordinate the inspection as part of the installation.
Yes. Properly sized mini-splits run longer, quieter cycles that remove moisture effectively. Correct sizing is especially important in west Houston’s humid climate so the system dehumidifies as well as cools.
Yes. Multi-zone systems allow one outdoor unit to connect to two or more indoor heads, each with its own temperature control. We design the system so each zone is properly sized.
Yes. Most modern ductless systems are heat pumps and provide efficient heating for Katy’s mild winters as well as strong cooling for the long summer season.
Yes. We provide maintenance that includes filter cleaning guidance and periodic professional service to keep the system efficient and under warranty requirements.
