At Adam’s Plumbing and Heating, we know how crucial it is to keep your home or business comfortable. That’s why we provide high-quality mini-split system installations for both residential and commercial properties across the Colorado region, with a focus on areas like Evergreen, Idaho Springs, Golden, Lakewood, and Black Hawk/Central City.

What Is a Ductless Mini-Split System? 

A ductless mini-split system, also known as ductless heating, mini-split heat pump, or mini-split AC, is a type of heating and cooling system that operates without the need for ductwork. Instead of generating heat, it moves heat energy around. This system typically consists of an outdoor compressor unit connected to one or more indoor units.

Common Uses for Ductless Mini-Split Systems 

Mini-splits are commonly employed in two main scenarios:

1. Multifamily Housing

Ductless mini-splits are compact and flexible, making them ideal for zoning and cooling individual rooms and spaces. These modern heating systems feature a thermostat for each unit, allowing residents to control the temperature of their rooms independently without affecting other areas in the same building.


Installing a mini-split heat pump in multifamily housing can lead to energy savings, particularly when equipped with inverter technology. Unlike traditional heating systems that rely on ducts for heat distribution, mini-split ACs deliver heat directly to the desired areas, avoiding energy loss through ducts. The zoning capability of mini-split systems ensures that heat is distributed only where needed rather than heating the entire building unnecessarily.


Additionally, ductless mini-split systems are straightforward to install and maintain. Installation typically involves mounting the indoor units on walls or ceilings and connecting them to the outdoor unit through a small conduit containing refrigerant lines, electrical wiring, and a condensate drain. This streamlined process reduces labor time and disruption to the building compared to traditional systems.

2. Retrofitting Houses with Non-Ducted Heating Systems 

Split systems, including ductless mini-splits, are commonly used to retrofit houses with non-ducted heating systems. Homeowners with radiant panels or other non-ducted heating systems may opt to supplement or replace them with mini-split systems if they find their current heating insufficient.


Retrofitting a house with a ductless mini-split system can also enhance indoor air quality. These systems often feature advanced air filtration, removing dust, allergens, and other airborne pollutants, thus creating a healthier indoor environment for occupants and improving their overall quality of life.

Considerations When Installing a Mini-Split Heating System

When deciding whether to install a mini-split system, keep the following factors in mind:

Professional Installation

Professional installation is necessary due to the complexity of the system.

Multiple Indoor Units

A single outdoor unit can typically support multiple indoor units, allowing for the zoning of different areas.

Upfront Costs

Initial costs may be higher compared to traditional systems. Monthly expenses vary based on factors such as system size, efficiency rating, and climate.

Effectiveness in Large Areas

Mini-split systems may be less effective in very large spaces.

How Does a Mini-Split AC System Work?

In a mini-split AC system, the cooling process begins with the indoor unit drawing in hot air from the room. This hot air is then transported through pipes to the outdoor condenser unit. At the condenser, the hot air's energy is transferred to coils containing a coolant, causing the coolant to change from a liquid to a gas state as it absorbs the heat.

The gas coolant is then sent to the compressor inside the condenser unit, where it undergoes a process to convert it back into a liquid form. Once in liquid form again, the coolant is ready to absorb more heat from the indoor air.

The air handler then circulates the cooled air back into the room, initiating a continuous cooling cycle. This cycle repeats, gradually reducing the room's temperature until it reaches the desired comfort level.

Outdoor Unit: Compressor/Condenser

Located outside, this unit contains the compressor, condenser coil, and fan. Its main function is to release or collect heat from indoor or outdoor air.

Indoor Unit(s): Air Handling Unit (Evaporator)

These units exchange heat between the refrigerant and indoor air. They cool or warm the air by evaporating or condensing refrigerant in the indoor coil.


Connects outdoor and indoor units, housing refrigerant lines, electrical wiring, and condensate drain line. Protects components from damage and ensures organized installation.

Power Cable

Supplies electricity to the system. Must be properly sized and installed according to manufacturer's instructions and local codes.


Refrigerant Tubing

Connects outdoor and indoor units, facilitating heat transfer. Consists of liquid and suction lines, carrying refrigerant to absorb or release heat.

Drain Line

Removes condensate to prevent system damage. Routes moisture from evaporator coils to prevent buildup.
