Mini-Split Installation & Repair Specialists in Lake County & El Dorado County, CA

Mini-Split Installation & Repair Specialists in Lake County & El Dorado County, CA 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.

For homes without existing ductwork — additions, garage conversions, ADUs, or older houses — a properly installed mini-split is often the fastest path to 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.
