Ductless mini-split systems offer a flexible, efficient solution for cooling and heating spaces in Katy, TX homes where traditional ducted systems aren’t practical or cost-effective. Whether you’re looking to condition a room addition, a garage conversion, a detached workshop, a sunroom, or simply an area of your home that your central system can’t reach effectively, a ductless AC system from Air Tech of Katy delivers targeted comfort without the need for major ductwork.
What Is a Ductless Mini-Split System?
A ductless mini-split system consists of two main components: an outdoor compressor unit and one or more indoor air-handling units mounted on the wall, ceiling, or floor of the space being conditioned. The indoor and outdoor units are connected by refrigerant lines run through a small hole in the wall — no ductwork required.
Most mini-split systems are heat pumps, meaning they provide both cooling and heating from a single unit, making them a year-round comfort solution for Katy homes. They’re particularly well-suited to Katy’s climate, where cooling demand is high for most of the year and moderate heating is needed during winter months.
Ductless AC Installation in Katy, TX
Proper installation is critical to getting the full efficiency and comfort benefits from a ductless system. Air Tech of Katy’s licensed HVAC technicians handle every aspect of the installation:
- Sizing and system selection. We calculate the correct capacity (BTUs) for your space based on room dimensions, sun exposure, insulation, ceiling height, and other factors. An improperly sized unit will either short-cycle or struggle to maintain temperature.
- Indoor unit placement. We position the indoor unit for optimal airflow and aesthetics, taking into account ceiling height, furniture layout, and wall construction.
- Outdoor unit siting. We locate the outdoor unit for proper drainage, adequate airflow, and code-compliant clearances.
- Refrigerant line installation. Lines are run cleanly and professionally, typically through exterior wall penetrations with weatherproof covers.
- Electrical connection and commissioning. We complete all electrical work, charge the system, and test full operation before calling the job complete.
