Aesthetically Pleasing

Ductless mini-splits offer comfort with little modification to your home's current structure. Conventional central air conditioning requires air duct systems, which tend to be bulky and can require special structural attention. Ductless mini-splits use copper refrigeration tubing and multiple air handlers to move air throughout the home. The result is whole home comfort at minimum cost.

Flexible Comfort

Ductless mini-split systems offer zoning at minimal cost. Each zone receives its own dedicated air handler, allowing for precise control of the area's temperature and fan speed. A ductless mini-split system can contain up to four zones per outdoor unit (with options for multiple outdoor units). A wireless remote in each zone allows the homeowner to adjust each zone to his or her own comfort level.

Low Impact Installation

Copper tubing running through a small 3 to 4-inch opening in the wall or ceiling easily connects the indoor and outdoor units. Refrigerant is cycled through the lines from the outdoor condensing unit to the indoor unit, where the air is quietly distributed to the interior space. Because installation is easier, you save drastically on labor costs compared to traditional air conditioning.

About Ductless Mini Splits Heat Pumps

Ductless mini-split systems like traditional air conditioning systems locate noisy components outside, however ductless mini-splits also eliminate the need for furnace blowers and ductwork, meaning they are great for retro-fit or boiler occupied homes. By eliminating these components, homeowners experience less HVAC system related noise and are no longer restrained by duct limitations. In addition, ductless mini-splits can provide multi-zoned comfort.

Even more remarkable, these same units have heating capabilities in the winter, absorbing heat from the outside air and moving it indoors to heat your home (Heat Pumps). The result? Efficient cooling and heating for year-round, whole-house comfort in most climates.

LeBlanc Heating has several testimonials from customers which claim that their installed ductless mini-split system has reduced their fuel consumption as much as 45%. Decreasing your carbon footprint through the reduction of fossil fuel consumption is just an added benefit.

Who Should Consider Ductless Mini Splits?

With the ever-increasing energy costs, many energy conscious homeowners have realized the benefits of ductless mini splits as an ideal solution. Heat pumps are incredibly efficient and mini split systems offer maximum efficiency, allowing you to save up to 40% on your annual heat costs. Ductless mini split heating systems are perfect for homes that do not have existing ductwork. Mini split systems allow you to cool, or heat specific areas in your home, these zoning capabilities allow people who prefer different temperatures to agree on a comfortable temperature all year round. Mini splits also come in a variety of shapes and sizes, there are both ducted and ductless models, but there are also floor units, wall units and ceiling cassettes. Different unit styles can be mixed and matched, for instance a homeowner can have a single heat pump outside connected to a ducted mini split in the attic and a wall unit in the living room. Flexibility, makes ductless mini splits adaptable to nearly any home. Investing in a mini split system can truly be an invaluable upgrade!

Types of Mini Split Air Handlers

Air conditioning systems have come a long way from the traditional bulky window units. Mini split systems, also known as ductless systems, are a prime example of this evolution. They are efficient, sleek, and adapt well to various architectural needs. As with many modern cooling and heating systems, mini splits offer a range of design and installation options. At A.J. LeBlanc Heating, we pride ourselves on installing all major mini split brands, including giants like Mitsubishi, LG, and Daikin. Let's delve into the different types of mini split air handlers available in the market:

Wall-Mounted Air Handlers

Appearance: These units are sleek and are designed to be mounted high on a wall.


  • Most common and typically the easiest to install.
  • Ideal for retrofit additions to homes.
  • Available in various designs and colors to match the interior dĂ©cor.


  • Might not be suitable for rooms with limited wall space or where aesthetics is a major concern.

Floor Mounted Air Handlers

Appearance: These resemble small radiators and are installed at the base of a wall.


  • Perfect for rooms with limited wall space or rooms with lots of windows.
  • They can be recessed into the wall, making them less obtrusive.


  • They consume floor space, which might be undesirable for some homeowners.

Ceiling-Cassette Air Handlers

Appearance: These are installed flush with the ceiling, with only the grille showing.


  • They distribute air evenly in four directions.
  • Suitable for large open spaces like commercial settings or spacious living rooms.
  • They are almost invisible, with only a slim part showing on the ceiling.


  • The installation process is more complex.
  • Ceiling space is needed, which might not be available in every home.

Concealed or Ducted Air Handlers

Appearance: These are hidden in the ceiling or behind walls, with only the ductwork and vents visible.


  • Offers the most discreet appearance since the unit is entirely hidden.
  • Can cool multiple rooms if combined with a small network of ducts.


  • Installation is more invasive, requiring ceiling or wall work.
  • Maintenance might require access to the concealed unit.

Mini Split Air Handler Flexibility

One of the standout features of mini split systems is their incredible flexibility, allowing homeowners to cater to diverse room requirements. With just a single outdoor unit, you can seamlessly connect multiple indoor air handlers of varying types, be it wall-mounted in the bedroom, ceiling-cassette in the living area, or floor-mounted in the sunroom. This adaptability not only ensures that each space gets tailored cooling or heating but also streamlines the external appearance of the setup, with just one outdoor unit catering to the entire home's needs. It's a blend of convenience, aesthetics, and efficiency rolled into one system.

Choosing the Right Air Handler for You

The right air handler largely depends on your specific needs and the architectural constraints of your home. While the wall-mounted units are versatile and fit most settings, a concealed or ducted system may better serve homeowners who want a completely seamless look. Floor-mounted units are perfect for spaces like sunrooms where wall space might be at a premium. For larger open spaces, the ceiling-cassette units are hard to beat.

A.J. LeBlanc Heating, with its vast experience in installing all major mini split brands, is well-equipped to guide you through the selection process. Whether it's the high-performing Mitsubishi units, the stylish LG systems, or the reliable Daikin models, we ensure a seamless integration into your home's design, ensuring optimal performance and aesthetic appeal.

The world of mini split air handlers is diverse and offers solutions tailored for every home. With the right choice, you can enjoy efficient cooling and heating without compromising on style.
