Our Mini-Split Services

Complete Ductless Mini-Split Solutions

Mini-splits are ideal for adding comfort to specific areas of your home without the cost and disruption of installing ductwork. Whether you need a new installation, a repair, or routine maintenance, our team delivers expert service.

Installation

Mini-Split Installation

Ductless mini-split systems consist of an outdoor compressor unit connected to one or more indoor air handlers by a small refrigerant line—no ductwork required. This makes them perfect for room additions, finished basements, attic conversions, sunrooms, garages, and older homes without existing duct systems.

Our technicians design and install mini-split systems that deliver precise comfort exactly where you need it. Single-zone systems handle one room, while multi-zone configurations can serve multiple areas from a single outdoor unit, giving you independent temperature control in each space.

Repair

Mini-Split Repair

Mini-split systems use inverter-driven compressors and sophisticated electronics that require specialized diagnostic knowledge. Our technicians are trained to work with these advanced systems, reading error codes, testing inverter boards, and diagnosing refrigerant circuit problems specific to ductless equipment.

Whether your mini-split is displaying error codes, leaking water, making unusual noises, or simply not keeping up, we have the expertise to diagnose the problem and get your system back to full performance.

Maintenance

Mini-Split Maintenance

Mini-split systems require regular maintenance to perform efficiently and avoid problems. The indoor air handlers collect dust and debris on their filters and coils, and the condensate drainage system needs to stay clear to prevent water damage. Without regular cleaning, efficiency drops, odors develop, and components can fail prematurely.

Our maintenance service includes thorough cleaning of indoor and outdoor units, filter service, condensate drain clearing, refrigerant check, and electrical inspection. We recommend annual service at minimum, with twice-yearly service for systems that run year-round.
