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.

Google review

“I had the great pleasure of working with Geordie on a mini-split project for my home. His customer service was outstanding — he maintained excellent communication throughout the entire process and patiently answered every question I had.”

“I had been researching mini-splits for a while, but the quotes I received from other companies were inconsistent and consistently high. Most of the other contractors who came out never even looked in my attic and tried to steer me toward locations that were more convenient for them rather than what I actually wanted. Geordie was different — he came to the house, listened carefully, inspected the attic, and provided a straightforward, honest quote.”

“We had a 27k BTU outdoor unit installed, paired with an 18k BTU wall-mount unit in the family room and a 12k BTU ceiling cassette in the master bedroom. All three units were installed professionally. They protected everything that could get messy and cleaned up very nicely after themselves. I would absolutely recommend River City for any cooling and/or heating needs.”
