Heating and Cooling Without Ductwork

Mini split and inverter system installation serving Bozeman and Livingston homes and mountain properties.

If your Bozeman home lacks ductwork or you need climate control in a new addition, a ductless mini split system delivers year-round heating and cooling without the complexity of traditional forced air. Many mountain properties and older homes in Bozeman rely on these systems for their ability to operate quietly and maintain precise temperature control in spaces that would otherwise be difficult to condition.


Granite Peak Mechanical Services installs mini split and inverter systems designed to handle both Montana winters and summer heat. Each installation includes indoor air handler mounting, refrigerant line connection, exterior condenser placement, and electrical integration. The inverter technology adjusts output based on real-time conditions, reducing energy consumption and providing consistent comfort without the cycling common in older systems.

Zoned Comfort Built for Mountain Homes

Your installation begins with a site evaluation to determine the number of indoor units required, ideal mounting locations, and condenser placement that minimizes visual impact while maintaining clearance for snow load and drainage. In Bozeman, wall-mounted air handlers are the most common choice, though ceiling cassette units work well in open floor plans or commercial settings.


After installation, you will notice immediate temperature stability in the targeted space, with no drafts or temperature swings. The system operates quietly enough that you may forget it is running, and the wireless remote allows you to adjust settings without moving from your chair.


Each system includes a warranty covering compressor and refrigerant components. Routine maintenance involves cleaning filters and checking refrigerant levels. The system does not replace a whole-home furnace but serves as a highly efficient solution for specific rooms, detached garages, or spaces where traditional ductwork is impractical or unavailable.

Questions homeowners in Bozeman typically ask before installation

Homeowners often want to understand how the system handles extreme cold, what maintenance looks like, and whether it works for their particular layout. The following addresses those concerns with detail drawn from installations across the region.

What temperature range can a mini split handle in Bozeman and Livingston winters?

Modern inverter systems maintain full heating capacity down to negative temperatures, typically to negative 15 degrees Fahrenheit or lower depending on the model. Many Bozeman homes use them as primary heat sources in smaller spaces or as supplemental heating in rooms that would otherwise rely on baseboard electric or wood stoves.
How often does a mini split system require service?
You should clean or replace indoor filters every four to six weeks during active use, and schedule professional maintenance annually to check refrigerant levels, clean coils, and inspect electrical connections. These steps prevent loss of efficiency and extend compressor life.
What happens if the outdoor unit gets buried in snow?
The condenser must remain clear for airflow and drainage. Installation includes mounting the unit on a raised platform or wall bracket to reduce snow contact, and you should clear heavy accumulation after storms to maintain proper operation.
How many indoor units does a typical Bozeman home need?
It depends on the number of rooms you want to condition and whether walls or doors separate them. A single outdoor condenser can support up to eight indoor units, but most residential installations use one to three units covering main living areas, bedrooms, or additions.
Why would I choose a mini split over extending my existing ductwork?
Ductwork installation in an existing home often requires cutting into walls, ceilings, and insulation, which increases labor and material costs significantly. A mini split requires only a three-inch penetration for refrigerant lines and wiring, making it faster, less invasive, and more cost-effective in retrofit applications.

Granite Peak Mechanical Services works with several inverter system manufacturers to match equipment to the specific heating and cooling load of your Bozeman property. If you want to add climate control to a space that currently has none, or if you are replacing an aging baseboard system, reach out to discuss your layout and usage patterns.
