Ductless Mini Split Installation and Repairs


Easy Heating and Cooling with Mini Splits

Mini split systems are rapidly gaining popularity due to their seamless installation, high energy efficiency, and compact design. In many countries, these systems are so prevalent that new homes and offices are built with ductless mini split installation in mind. But what makes them truly versatile is their ease of installation in older homes as well, requiring no extensive remodeling or ductwork.


Why Choose a Mini Split System?

  • Simple Installation: Mini splits require no ductwork, making the installation process straightforward and less invasive than traditional HVAC systems.
  • Energy Efficiency: With their ductless design, mini splits lose less than 5% of the cooling and heating energy, compared to up to 40% for traditional ducted systems.
  • Space-Saving: Their compact size and flexibility allow for easy placement, making them ideal for smaller spaces or homes with challenging layouts.
  • Versatility: These systems can heat in the winter and cool in the summer, offering year-round comfort.
  • Quiet Operation: Mini splits operate at lower noise levels, allowing for a peaceful indoor environment.


Different Types of Ductless Mini Split Systems

Ductless mini split systems have gained popularity due to their efficiency, versatility, and easy installation. While the basic principle remains consistent – a combination of an indoor unit and an outdoor compressor/condenser – there are several variations tailored for specific needs and preferences. Here are some of the popular types of ductless mini split systems:

1. Wall-Mounted Mini Split Systems

Wall mounted mini split

Wall mounted mini split

  • Best For: Most common residential applications.
  • Features: Mounted high on the wall, these units are the most common type of mini split systems.
  • Pros: Efficient, relatively easy to install, and less intrusive in room aesthetics.
  • Cons: Can be more visible than other ductless options.


2. Ceiling Cassette Mini Split Systems

Cassette type mini split

Cassette type mini split

  • Best For: Commercial spaces or homes with drop ceilings.
  • Features: Mounted into the ceiling with just the grille showing.
  • Pros: Space-saving, distributed airflow, blends well with interior aesthetics.
  • Cons: More complex installation, typically larger and more expensive than wall-mounted units.


3. Floor-Mounted Mini Split Systems

  • Best For: Rooms without a lot of wall space, or where the ceiling is not an option.
  • Features: Units are mounted low on a wall or standing on the floor.
  • Pros: Good for spaces with limited wall space, easy to access for maintenance.
  • Cons: Can take up floor space, and may not distribute air as evenly as wall or ceiling-mounted options.


4. Concealed Duct Mini Split Systems

  • Best For: Homeowners who want a less visible indoor unit.
  • Features: The indoor unit is hidden in the ceiling or wall with only air vents visible.
  • Pros: Discreet, allows for a more uniform room aesthetic, can service multiple rooms.
  • Cons: More complex installation, requires minor ductwork for air distribution.


5. Multi-Zone Mini Split Systems

  • Best For: Homes or businesses needing multiple indoor units connected to a single outdoor unit.
  • Features: One outdoor unit can connect to multiple indoor units.
  • Pros: Energy-saving, offers individualized climate control in different rooms.
  • Cons: Higher upfront costs, requires more extensive installation.


When selecting the right ductless mini split system for your space, it’s essential to consider the specific requirements of each room, the overall layout of your property, and your budget. A qualified HVAC professional can provide guidance tailored to your needs.


How Does Your A/C Mini Split Heat Pump Work?

Investing in a mini split heat pump from Milani is an excellent decision if you’re looking for a versatile and energy-efficient heating and cooling system. Here’s a simple breakdown of how the system works across the seasons:

Basic Principle

The fundamental principle behind a heat pump is its ability to move heat from one place to another. Instead of generating heat, a heat pump transports it. This makes heat pumps incredibly energy-efficient compared to traditional heating systems that burn fuel or use electric resistance heating.

Winter Heating

  1. Heat Collection: When in heating mode, the outdoor unit of the heat pump extracts heat from the external air—even when it’s cold outside.
  2. Heat Transfer: The heat pump’s compressor pressurizes this collected heat, raising its temperature even further.
  3. Heat Distribution: The indoor unit or units (also known as mini splits) then distribute this heat throughout your home.

Summer Cooling

  1. Heat Extraction: In cooling mode, the heat pump acts in reverse. It extracts heat from the indoor air.
  2. Heat Expulsion: The heat is then transferred to the outdoor unit and released into the external environment.
  3. Cooling: As a result, the indoor air is cooled and redistributed into your home.

Reversing Valve

The key component that enables a heat pump to both heat and cool your home is the reversing valve. This device switches the direction of the refrigerant flow, thereby changing the heat pump from a heating unit to a cooling unit (and vice versa) based on your needs.

Versatility and Choices

Milani offers a range of mini split heat pump options, including models from Mitsubishi and Lennox. These units can offer various features, such as smart home compatibility, zone-specific controls, and more.

Why Choose a Mini Split Heat Pump?

  • Two-in-One Functionality: Acts as both a heater and an air conditioner.
  • Energy Efficiency: Consumes less energy compared to traditional systems.
  • Targeted Climate Control: Provides the ability to heat or cool specific rooms.
