Repair & Installation of Mini-Split Units

Are you considering upgrading to a new type of system for your home? If so, you may want to consider the advantages of a ductless mini-split system, which is an extremely efficient way of cooling and heating your home. Systems that do both heating and cooling are often an excellent investment for homeowners who are seeking an alternative to basic HVAC systems. At Carney & Son 72 Degrees, we can provide you with professional installation and repair services if you would like to invest in a ductless mini-split system.

Advantages Of a Mini-Split System

Mini-split systems are superior to standard duct installation for some people. Ductless units of this type have programmable thermostats for each part of the house, saving you both on cost and energy. Your occupants or family members will likely find this to be increasingly comfortable compared to a home with one temperature throughout.

Ductless Mini Split Case Studies

  • “The results of the heating experiment from Ashley et al. (2020) showed that MSHP system saved 22% to 45% energy during the central experiment. Zonal heating experiment savings ranged from 7% to 35%.” ~Department of Mechanical Engineering, The University of Texas at Tyler, United States of America
  • “Among the six test sites, median cooling energy use was reduced by 10.9 kilowatt-hours per day (kWh/day) (37%) and heating energy use was reduced by 13.2 kWh/day (59%). Assuming a current installation price of about $3,500, the economics of this measure are potentially attractive; they include a suggested payback of 12 years and an 8.1% annual rate of return.” ~US Department of Energy
  • “Average annual savings for the units were estimated at $868 including both heating and cooling mode operation. Average annual heating mode savings were estimated at $624, and cooling mode, at $244. There are also a number of non-energy benefits that were not quantified, including increases in property values; increases in the marketability of the units, tenant retention, and overall satisfaction; and improved health, safety, and comfort of tenants.” ~Sustainable Technologies Evaluation Program

Understanding Ductless Mini Split Systems

What is a Ductless Mini Split System?

A ductless mini-split system is a highly efficient and versatile air conditioning and heating solution, especially suited for homes and buildings where traditional ducted HVAC systems might not be feasible. Unlike conventional systems that rely on a network of ducts to distribute air, ductless mini-splits directly condition the air in each room.

Key Components:

  • Outdoor Unit: This contains the compressor and condenser components. It’s installed outside the building and is responsible for expelling heat during the cooling process.
  • Indoor Unit(s): Air-handling units are installed in each room or zone. They are sleek and typically mounted on walls. Each unit can be controlled independently, providing personalized temperature settings.
  • Refrigerant Lines: These connect the outdoor and indoor units, carrying the refrigerant that helps with the heat exchange.
  • Control System: Remote controls or smart thermostats let you easily regulate the temperature settings in each zone.

Types and Models

Ductless mini splits come in various types and models, each suited for different needs and spaces.

Single-Zone Systems: Ideal for individual rooms or additions where only one indoor unit is connected to an outdoor unit. Perfect for new additions, garages, or home offices.

  • Pros: Cost-effective for single-room solutions, easy to install.
  • Cons: Limited to one zone; not ideal for whole-house conditioning.

    Multi-Zone Systems: These systems can connect multiple indoor units to a single outdoor unit, allowing different rooms or zones to be conditioned independently.

    • Pros: Customizable for whole-house comfort, energy-efficient as each zone can be controlled separately.
    • Cons: Higher initial investment, more complex installation.

      Ceiling Cassette and Floor-Mounted Models: These are variations in indoor units. Ceiling cassettes are mounted into the ceiling, offering a discreet look, while floor-mounted models are ideal for limited wall space.

      • Pros: Flexible installation options, suitable for unique room layouts.
      • Cons: Consider aesthetics, as they may be more visible.

      Why Ductless Mini Splits are Ideal for Charleston’s Climate

      Charleston, SC, is known for its hot, humid summers and mild winters. This unique climate leads to unique considerations for heating and cooling systems.

      • Handling Humidity and Heat: Ductless mini splits are excellent at managing high humidity levels. They provide steady, consistent cooling without the overcooling that often happens with traditional systems. 
      • Energy Efficiency: With Charleston’s extended warm seasons, energy efficiency is a major concern. Ductless systems are more energy-efficient than traditional HVAC systems, as they avoid energy losses typically associated with ductwork.
      • Zoned Comfort: Charleston homes often have rooms with varying exposure to sunlight, leading to uneven temperatures. Ductless systems allow for zoned temperature control, ensuring each room is conditioned exactly how you want them to be.
