When you need efficient heating and cooling without traditional ductwork, McCandless Plumbing & Excavation provides expert mini-split HVAC installation that delivers precise climate control for any space. Our ductless mini split systems offer energy-efficient comfort with individual room temperature control, making them perfect for home additions, older homes without existing ductwork, or spaces where traditional HVAC systems aren’t practical.
We install leading brands including Mitsubishi Electric, Daikin, LG, Samsung, Fujitsu, and others to create custom ductless air conditioning and heating solutions that maximize comfort while minimizing energy costs.

Mini-split systems consist of two main components connected by refrigerant lines:
Indoor Air Handlers:Wall-mounted units that distribute conditioned air directly into living spaces, controlled by wireless remote controls for precise temperature management.
Outdoor Condensing Units:Compact units housing the compressor and condenser that can serve multiple indoor units for multi-zone mini split applications.
Unlike traditional systems that lose energy through ductwork, ductless heat pump technology delivers conditioned air directly where it’s needed, providing superior efficiency and comfort.


Perfect for individual rooms, home additions, or spaces requiring independent climate control. Each indoor unit connects to its own outdoor unit for dedicated heating and cooling.


The most common indoor unit style, these sleek units mount high on walls and distribute air efficiently throughout the room using advanced fan technology.

Alternative indoor unit styles for spaces where wall mounting isn’t ideal, providing the same efficiency with different installation options.
Inverter Technology:Variable speed compressors adjust output to match heating and cooling demands precisely, providing consistent temperatures with maximum energy efficiency.
Heat Pump Technology:Most mini-splits provide both heating and cooling, using refrigerant to transfer heat rather than generating it, making them highly efficient in moderate climates.
High SEER Ratings:Modern systems achieve SEER ratings of 20+ for cooling efficiency, significantly higher than traditional central air systems.
HSPF Ratings:Heating efficiency ratings of 10+ make mini-splits excellent choices for year-round comfort in most climates.


Mini-split systems are just one of many advanced climate control options we offer, and our completeheating and cooling services include traditional HVAC systems, radiant heating, and energy-efficient solutions for every home comfort need.
Mini-split systems provide excellent cooling and heating for living spaces, but for ultimate comfort, many homeowners combine them withradiant floor heating technology to create luxurious warm floors during cold months.
While mini-splits handle space heating and cooling efficiently, they don’t provide domestic hot water, making tankless combi boiler systems an ideal complement for comprehensive home comfort and hot water supply.
Experience the comfort and efficiency of ductless mini-split technology in your home. Our certified installers provide professional split system installation that delivers years of reliable, efficient climate control. From single-zone solutions to comprehensive multi-zone systems, we create custom installations that fit your specific needs and budget.

Mini-split systems offer exceptional energy efficiency compared to traditional HVAC systems:
No Ductwork Losses:Eliminate the 20-30% energy losses common in traditional ductwork systems.
Zoning Capabilities:Heat and cool only the spaces you’re using, rather than the entire home.
Variable Speed Operation:Inverter technology adjusts capacity to match demand precisely, avoiding the energy waste of constant on/off cycling.
High-Efficiency Ratings:SEER ratings above 20 and HSPF ratings above 10 provide significant energy savings compared to older systems.
Home Additions:Perfect for new spaces without existing ductwork access.
Older Homes:Retrofit solutions that don’t require extensive ductwork installation.
Room-Specific Comfort:Independent temperature control for bedrooms, offices, or workshops.
Supplemental Heating/Cooling:Enhance existing systems in problem areas or high-use spaces.
