What Is a Mini-Split System?

A ductless mini-split system consists of an outdoor condenser and one or more indoor air-handling units. Unlike traditional forced-air systems, mini-splits require no ductwork. Each indoor unit connects to the outdoor condenser via a compact line set, allowing individual temperature control in each zone. Systems may include:

Single-zone mini-splits for one room or area
Multi-zone configurations to heat or cool multiple spaces independently
Heat pump models for year-round climate control

A white, ductless mini-split air conditioning unit is mounted on a light-colored wall with a ceiling vent above it.

Benefits of Ductless Mini-Splits

Zoned Comfort: Adjust temperature settings in individual rooms without affecting the entire building. Perfect for bedrooms, home offices, sunrooms or additions.
Energy Efficiency & Savings: Variable-speed compressors and inverter technology modulate output to match demand, reducing energy consumption and lowering utility bills.
Improved Indoor Air Quality: Advanced multi-stage filtration captures dust, pollen and other airborne particles. Many units also offer anti-mold and anti-bacterial features for a healthier living environment.
Quiet Operation: Indoor units operate at whisper-quiet noise levels, typically under 30 decibels on low fan speeds, making them ideal for bedrooms, libraries and media rooms.

Our Installation Process

Site Assessment & Load Calculation
- Inspect room dimensions, insulation, window orientation and sun exposure
- Perform Manual J load calculation to determine optimal system capacity ‍
Indoor Unit Placement & Bracket Installation
- Select a discreet, structurally sound location on an interior or exterior wall
- Secure mounting bracket level and plumb to ensure proper refrigerant drainage ‍
Line-Set Hole Drilling & Concealment
- Drill a single 3-inch hole for refrigerant lines, condensate drain and wiring
- Seal penetrations with weather-resistant materials and conceal with trim covers ‍
Refrigerant Lines & Electrical Hookup
- Run copper refrigerant lines and electrical conduit between indoor and outdoor units
- Connect to a dedicated circuit breaker and install required disconnects ‍
Outdoor Condenser Setup
- Position condenser on a level pad or wall brackets to minimize vibration
- Verify proper clearance around the unit for airflow and maintenance access ‍
Vacuum & Refrigerant Charging
- Evacuate air and moisture from the refrigerant lines using a high-vacuum pump
- Charge system to manufacturer specifications for optimal cooling and heating performance
‍System Testing & Calibration
- Energize the system, verify compressor operation and inspect for leaks
- Calibrate thermostat settings and remote control functions ‍
Customer Education & Warranty Review
- Demonstrate basic operation, filter maintenance and error-code troubleshooting
- Review manufacturer warranty coverage and our workmanship guarantee
