Mini-Split Repair
Common problems include weak cooling, water leaks, control errors, electrical failures, dirty coils, fan problems, refrigerant performance issues, and communication faults between indoor and outdoor equipment. We diagnose the complete system before recommending repair.
Mini-Split Maintenance
Routine service helps keep indoor units, filters, coils, drain lines, outdoor equipment, and electrical connections in better condition. Because ductless units may operate in individual rooms for long periods, filters and indoor coils need regular attention.
Mini-Split Installation
A proper installation requires correct equipment sizing, indoor-unit placement, outdoor-unit placement, condensate planning, electrical service, line-set routing, and startup testing. We review how the space is used and recommend a configuration that fits the property.
Single-Zone and Multi-Zone Systems
A single-zone system connects one indoor unit to one outdoor unit. Multi-zone systems connect several indoor units to compatible outdoor equipment. The best layout depends on the number of spaces, individual comfort needs, property design, and equipment limitations.

Mini-Split FAQs
Can one mini-split cool an entire home?
It depends on the property and system design. Some homes use multiple indoor zones, while others use mini-splits only for selected spaces.
Do mini-splits provide heat?
Many ductless systems are heat pumps and can provide both heating and cooling.
