Ductless Mini-Split Installation
Ductless mini-split systems offer efficient, flexible comfort without the need for traditional ductwork. Our technicians evaluate your home’s layout, room usage, and comfort goals to design a system that delivers consistent temperature control. We handle indoor unit placement, outdoor condenser installation, refrigerant line routing, electrical connections, and full system testing to ensure reliable performance.
Ductless Mini-Split Repair
When a mini-split system stops performing properly, comfort can decline quickly. We diagnose and repair common issues such as refrigerant leaks, communication errors, sensor failures, drainage problems, fan motor issues, and control board malfunctions. Whether your system is single-zone or multi-zone, our technicians restore dependable operation efficiently and safely.
Multi-Zone Mini-Split System Setup
Multi-zone mini-split systems allow multiple rooms or areas to operate independently from a single outdoor unit. Proper design and installation are critical for balanced performance. We configure zoning, indoor unit placement, and system controls to ensure consistent comfort and efficient operation throughout your home or business.
Mini-Split Controls & Thermostat Integration
Accurate controls are essential for mini-split performance. We install and configure wall-mounted controllers and compatible smart thermostat solutions to ensure proper communication, scheduling, and temperature accuracy. Correct setup helps maximize comfort while preventing system strain.
