Installation Options for Your Ductless Mini-Split

Homeowners in the market for a new HVAC unit have more options than ever. In addition to the conventional furnace and air conditioning system, as well as the increasingly popular heat pump, they have a relative newcomer to consider: The ductless mini-split. This efficient system has gained popularity in recent years thanks to its powerful heating and cooling capacity and versatility as a comfort solution for the whole home, single room, or new addition.

Here’s What Makes a Ductless Mini-Split So Efficient

If you don’t already know, those long runs of ductwork can be massively inefficient, losing as much as 30% of conditioned air to the attic. The mini-split bypasses ducts to deliver comfort directly from the source: An indoor air handler mounted to your wall or ceiling (more on that later) quietly produces warm or cool air.

That’s one reason why a ductless mini-split has an efficiency edge over other HVAC systems. Another reason: zoning. A central air system works hard to distribute warm or cool temperatures throughout the whole house. A mini-split, however, delivers targeted comfort by using home automated zoning systems. When you have multiple air handlers, you can create comfort zones. You can turn off the air handlers upstairs when you’re spending most of your time downstairs and vice versa. The energy-saving potential is significant.

Here’s Why a Ductless Mini-Split is Versatile

A mini-split consists of one or more indoor air handlers and an outdoor compressor. Connecting these units is a conduit containing separate lines for power, refrigerant, and drainage. Because ducts are taken out of the equation, you have several AC installation possibilities to consider.

For the new addition: A ductless mini-split will operate independently of your existing HVAC, so you don’t need to worry about extending the ductwork into your new space.

For the detached studio or in-law suite: If you have an outbuilding for an office, studio, or guest quarters, a ductless mini-split will provide efficient comfort.

For the garage: If you converted your garage into a livable space or just need temperature control while you’re tinkering, opt for a mini-split.

For the home without existing ductwork: Homes that don’t have ducts will require a major retrofit to accommodate a central air system. A ductless mini-split solves that dilemma because its installation would be far less disruptive, making it an ideal comfort solution for a historic home.

Placement Options for Your Mini-Split

  • Wall mount: The air handler can mount flush against the upper third of an exterior wall. It will extend about 12 inches from the wall.
  • Ceiling suspended: This option is best for high ceilings because the indoor unit will protrude overhead about 14 to 16 inches.
  • Ceiling cassette: The air handler is recessed into the ceiling behind a grill. It’s the best option if you want to keep the equipment out of sight.

Turn to the Ductless Installation Experts

While a ductless mini-split is comparatively easy to install, the HVAC installation process for this system still requires professional expertise. Like a conventional HVAC system, a mini-split will need to be sized correctly, taking into account your home’s square footage, layout, and the number of air handlers required. A professional will also need to cut and charge the refrigerant lines and hardwire the unit into your electrical system. Those are definitely not DIY jobs.
