Mini-Split Repair in the Sacramento Area, CA

Ductless mini-split outdoor units with refrigerant lines

Common problem we solve

Indoor head not blowing cold or hot

Refrigerant pressure check and reversing valve diagnosis

What To Expect

When a ductless mini-split stops cooling, stops heating, leaks water, or throws a communication error, you need a tech who's actually trained on inverter systems — not someone guessing from central-AC experience. River City Heating & Cooling provides same-day mini-split repair across the Sacramento area on every major brand: Mitsubishi, Daikin, Fujitsu, LG, Senville, and MRCOOL. Diagnosis is brand-specific, parts come off the truck when possible, and pricing is always written down before any work begins.

Mini-splits are precise pieces of equipment — refrigerant charge tolerances are tight, communication wiring between the heads and the outdoor unit is sensitive, and inverter compressors fail differently than single-speed compressors. We use manufacturer-specific service tools and error-code references so the root cause gets fixed, not just the symptom. Most repairs finish in one visit.
