Ductless mini splits are one of the most flexible cooling and heating solutions for Northern Colorado commercial spaces — they're ideal for restaurant kitchens, retail buildouts, office additions, server rooms, and historic buildings where running new ductwork is impractical or impossible. Accutemp Services installs, repairs, and maintains commercial ductless mini split systems from all major manufacturers, with the same 24/7 emergency dispatch and 30-day labor warranty backing every other Accutemp service.
Ductless mini splits work differently from traditional commercial AC: an outdoor condenser connects via refrigerant lines and a small wiring conduit to one or more indoor head units mounted on walls, ceilings, or in concealed enclosures. There's no ductwork — heating and cooling reach the space directly from the indoor unit. This makes them ideal for situations where ductwork is impossible (historic buildings), impractical (server rooms with strict temperature requirements), or expensive (restaurant kitchen build-outs that would require major construction). Multi-zone systems can serve 4–8 indoor heads from a single outdoor unit, providing zone-by-zone control without the complexity of variable-air-volume duct systems.
Accutemp services every major commercial ductless mini split brand — Mitsubishi Electric (M-Series, City Multi VRF), Daikin (Aurora, Quaternity, VRV), LG (Multi V, Multi V Water IV), Fujitsu (Halcyon), Gree, Samsung, and Panasonic. Common repairs include indoor unit blower replacement, outdoor condensing unit service, refrigerant leak detection on long line sets, condensate drain line clearing, control board diagnosis, communication wire troubleshooting, and remote control / wall thermostat replacement. Mini split systems also have unique failure modes — head unit drainage issues, refrigerant line set damage from rodents or contractors, and communication faults between indoor and outdoor units — that require brand-specific diagnostic procedures.
For Northern Colorado restaurants, mini splits solve a specific problem: kitchen heat gain. Even with a properly sized rooftop AC, kitchens generate so much heat from cooking equipment that ambient temperatures climb during service hours. A dedicated ductless mini split mounted in the kitchen ceiling pulls that heat directly from the source rather than waiting for it to circulate through the building. We've installed dozens of these systems for restaurants across Fort Collins, Loveland, Greeley, and the Denver metro — typically improving cook line working conditions and reducing the load on the main RTU simultaneously.
For retail and office spaces, mini splits enable building additions, conversions, and adaptive reuse projects that would otherwise require major HVAC overhauls. Adding a 1,000-square-foot retail space to an existing building? A multi-zone ductless system serves it without touching the existing ductwork. Converting a warehouse to office space? Multiple ductless heads provide zone control more efficiently than a new central system. Historic building conversion? Mini splits preserve architectural integrity since they don't require running new ducts. Our team consults on the design before installation, sizes equipment correctly for Northern Colorado's altitude and climate, and handles the entire installation including line set routing and electrical work.

Our Process
Application Consultation
For new installations, we evaluate the space, calculate cooling and heating loads at Northern Colorado altitude, and recommend the right system configuration — single zone, multi-zone, or VRF
Professional Installation
Our team handles the entire installation — outdoor unit mounting, line set routing through walls or ceilings, electrical work, communication wire pulling, indoor head positioning, and condensate drain piping
Brand-Specific Diagnostics
For repairs, we follow manufacturer-specific diagnostic procedures since mini split error codes and component layouts differ significantly between Mitsubishi, Daikin, LG, and other brands
Performance Calibration
Whether installing or repairing, we verify refrigerant charge, test airflow at each indoor unit, calibrate controls, and confirm communication between indoor and outdoor components before leaving
