Mini-Split Installation and Repair

Mini-Split Installation and Repair in Northern California

Not every technician is trained on ductless equipment, and mini-splits are different enough from central systems that experience matters. That's why we keep a dedicated team of mini-split specialists on staff, technicians who install and repair ductless systems every week, not once in a while.

Whether you're adding a single-zone unit to a converted garage or need multi-zone coverage across an entire home, our specialists handle the load calculations, line-set routing, and electrical work that determine whether a mini-split performs the way it's supposed to.

We also repair mini-splits we didn't install. If your system is throwing an error code, short cycling, or leaking, our team can diagnose almost any residential brand and get it back on track.

A Team That Only Does This

Ductless systems use variable-speed inverter compressors, refrigerant lines, and control boards that behave very differently from a standard split system. Our mini-split specialists train specifically on this equipment, so problems get diagnosed correctly the first visit instead of through trial and error.

We don't subcontract mini-split work out to a general HVAC crew. The same specialists who install your system are the ones who show up when it needs service later.

Installation Built Around How You'll Use It

A mini-split's performance comes down to how well it's sized and placed. We evaluate each room's heat load, recommend wall, ceiling cassette, or floor-mounted air handlers based on the space, and route refrigerant lines to minimize length and protect efficiency.

Homes without existing ductwork, such as additions, garage conversions, ADUs, or older houses, are often the best fit for a properly installed mini-split for reliable heating and cooling.

Common Mini-Split Repairs We Diagnose

Mini-splits are reliable, but when something goes wrong, the fix usually requires brand-specific knowledge of the control board and error code system. We regularly diagnose and repair:

• Blinking error codes or lockouts on the indoor unit
• Ice forming on the outdoor condenser or indoor coil
• Refrigerant leaks and low charge causing weak output
• Condensate drain clogs and water leaking from the air handler
• Noisy or vibrating outdoor compressors
• Wi-Fi modules and remotes that have stopped responding

Multi-Zone & Whole-Home Ductless Systems

A single outdoor condenser can power multiple indoor air handlers, giving you independent temperature control room by room. We design multi-zone layouts for whole-home ductless comfort, additions, and mixed setups where only part of a house needs supplemental heating or cooling.
