Ductless Mini-Split Systems: Efficient, Flexible Comfort
Experience exceptional comfort and energy savings with a ductless mini-split system from 911 Mechanical. Ideal for homes without ductwork, additions, or zoned spaces, these systems heat and cool precisely where you need it — with superior efficiency and control.
What Is a Ductless Mini-Split?
A ductless mini-split is a compact heating and cooling system that delivers conditioned air directly into individual rooms or zones without traditional ductwork. These systems feature:
A small outdoor compressor/condenser
One to several indoor air-handlers mounted on walls or ceilings
Individual controls (wireless thermostats or remotes) for each zone
Because they bypass ducting, they avoid the energy losses associated with leaky, uninsulated ducts — often accounting for more than 30% of space-conditioning energy usage.
How It Works
Popular Applications
uctless mini-splits are particularly effective in:
Older homes without existing ducts — retrofit becomes simple and cost-effective.
Sunrooms, enclosed patios, guest houses, workshops and other spaces needing separate comfort zones. Home offices, home theaters, “she sheds”, “man caves”, garages and other specialty rooms that traditional HVAC may not adequately serve.
New additions or remodels where extending ductwork may be difficult or impractical.
