Ductless Mini-Split Air Conditioning & Heating in Bloomington, MN

A mini-split is an air conditioning and heating system with an outdoor compressor unit connected to one or more indoor head units via refrigerant lines. Unlike central AC, it needs no ductwork. Indoor units mount on walls, ceilings, or floors, giving you flexible placement and zone control. Each zone can be set to its own temperature independently.

Window units are temporary and inefficient — they block windows, are noisy, and cool poorly. Mini-splits are permanent, quiet, efficient installations that mount discreetly on walls. They offer heating and cooling in one system, use far less energy, and look cleaner. A mini-split is a long-term comfort investment; a window unit is a short-term patch.

Installation requires EPA certification, refrigerant handling expertise, electrical work, and precise system calibration. Improper installation can damage equipment, void warranties, and create safety hazards. Hire a certified technician like Southside to ensure proper commissioning and peak performance.

Costs vary based on capacity, number of indoor heads, and installation complexity. A single-zone system is typically less than a whole-home multi-zone setup. We provide upfront quotes after assessing your home. Flexible payment options are available to fit your budget, and your system usually pays for itself through energy savings.

Yes. Mini-splits are typically 20–30% more efficient than window units or space heaters because they use inverter-driven compressors that adjust output to actual demand. They also let you heat or cool only occupied rooms, avoiding waste on empty spaces. Energy savings depend on your existing system and usage habits.

We install Lennox, GE, and other leading ductless brands with full expertise and parts support. We also service mini-splits from other manufacturers — bring us your system and we’ll diagnose and repair it.

We recommend professional maintenance twice per year — once before cooling season and once before heating season. These visits clean filters, inspect coils, verify refrigerant levels, and check electrical connections. Join our maintenance plan for scheduled service and discounted repairs.

Many mini-splits include heat pump technology, providing both cooling and heating. Heat pump systems are highly efficient, even in Minnesota winters, because they move heat from outdoors indoors rather than generating heat electrically. We can design a system that handles your full heating and cooling needs year-round.

Refrigerant leaks reduce cooling and heating output. Our technicians identify leaks using professional equipment, repair the leak, and recharge the system to specification. Refrigerant handling requires EPA certification, so this work must be done by a licensed professional.

Modern mini-split indoor units are much quieter than window units or older split systems — typically 20–30 decibels on low speed. The outdoor compressor unit is louder but located away from living spaces. Installation placement (not too close to bedrooms or seating areas) further reduces any noise impact.
