Mini Split Install

Mini split systems provide efficient heating and cooling without requiring ductwork. At Paragon Service Pros, we install ductless equipment for homes and light commercial spaces where traditional systems are impractical or inefficient. Our installation process focuses on correct sizing, secure mounting, and proper refrigerant setup so the system operates as designed from the first day of operation.

We evaluate the structure, insulation levels, and room layout before recommending equipment. A correctly selected unit avoids short cycling, maintains consistent temperatures, and helps reduce operating costs. Every installation includes system testing and performance verification before the project is considered complete.

Where Mini Splits Work Best

Ductless systems are designed to condition individual rooms or multiple zones independently. Because each indoor air handler controls its own area, you can maintain different temperatures throughout the building. This makes them especially useful in spaces where central ductwork cannot reach or would be difficult to modify.

Common installation locations include:

• Home additions and remodels
  
  
• Garages and workshops
  
  
• Sunrooms and enclosed patios
  
  
• Basements and converted attics
  
  
• Offices and small commercial suites
  
  
• Older homes without existing ducts
  
  

Many property owners also install multi-zone systems to replace baseboard heaters or window units. A properly installed ductless system can provide both heating and cooling from a single piece of equipment, simplifying comfort control.

Our Installation Process

A reliable mini split install requires more than mounting an indoor unit on the wall. The outdoor condenser, refrigerant lines, electrical wiring, and drainage must all be installed to manufacturer specifications. We follow a structured installation procedure to ensure long-term performance.

Our work typically includes:

• Load calculation to determine correct system capacity
  
  
• Placement planning for indoor and outdoor units
  
  
• Mounting and leveling of air handler brackets
  
  
• Routing insulated refrigerant line sets
  
  
• Installing dedicated electrical disconnect and wiring
  
  
• Creating a sealed wall penetration and line protection
  
  
• Condensate drain setup and leak prevention
  
  
• Evacuation of the system with a vacuum pump
  
  
• Refrigerant charge verification and startup testing
  
  

The evacuation step is particularly important. Removing moisture and air from the refrigerant lines prevents internal corrosion and protects the compressor. After the system is started, we check operating pressures, airflow, and temperature change to confirm proper function.

Single-Zone vs Multi-Zone Systems

Mini splits can be configured in different ways depending on the number of rooms you want to condition. A single-zone system uses one indoor air handler connected to one outdoor unit, making it ideal for a specific area such as a garage or addition. Multi-zone systems connect several indoor units to one outdoor condenser, allowing multiple rooms to operate independently.

We help determine which configuration fits your layout and usage patterns. For example, bedrooms may require different temperature settings than living areas. Zoning allows each space to operate only when needed, reducing unnecessary runtime and improving efficiency.

Electrical and Mounting Considerations

Proper electrical installation is essential for ductless equipment because the inverter compressor adjusts speed continuously. The system requires a correctly sized circuit and secure connections to avoid communication errors or nuisance shutdowns. Our technicians install the disconnect, verify voltage supply, and confirm communication wiring between components.

Indoor units must also be mounted in a location that promotes balanced airflow. We position the air handler high on the wall where circulation is unobstructed and avoid areas that could cause short airflow patterns. The outdoor condenser is placed on a stable pad or bracket to prevent vibration and allow service access.

Startup, Testing, and Homeowner Guidance

After installation, we run the system through both cooling and heating modes. This confirms the thermostat or remote communicates properly with the control board and that sensors respond correctly. We measure temperature output, verify fan operation, and ensure the condensate drain flows freely.

Before leaving, we review system operation with you, including:

• Remote control functions and mode selection
  
  
• Filter cleaning procedures
  
  
• Recommended maintenance intervals
  
  
• How to recognize early warning signs of a problem
  
  

Understanding basic operation helps you get consistent performance and reduces service calls caused by simple settings issues.

Long-Term Performance

A properly installed mini split system can operate for many years when maintained correctly. Because ductless equipment relies on airflow and clean coils, periodic service is important. Routine maintenance allows us to inspect electrical components, clean the indoor unit, and verify refrigerant levels before performance declines.

Paragon Service Pros installs ductless systems with attention to detail so the equipment operates efficiently and reliably. Our goal is to provide consistent comfort, quiet operation, and dependable performance through accurate installation and thorough system testing.
