Mini Split Installation Service in Stevensville, & Bitterroot Valley, Montana

Enjoy Optimal Heating & Cooling, Ductlessly

We're pioneers in bringing the efficiency of mini-split systems to homes and businesses across Stevensville and Bitterroot Valley, Montana. Mini-splits, also known as ductless heat pumps, are a game-changer in HVAC technology, offering both heating and cooling without the need for extensive ductwork. 


The heart of a mini-split is its inverter-driven compressor, which can modulate its speed to match the exact cooling or heating demand. This variable-speed technology means no more energy-wasting on/off cycles. Instead, you get precision climate control and energy savings of up to 40% compared to traditional systems.

Our installations typically involve an outdoor condensing unit connected to one or more indoor air handlers via small refrigerant lines. These sleek indoor units can be wall-mounted, ceiling-recessed, or floor-mounted to blend effortlessly with your decor. 


With 30 years of expertise, our NATE-certified technicians custom-design your system, considering factors like room size, insulation, and sun exposure. Our installation is backed by a strong warranty for your ultimate peace of mind.

What Makes Mini-splits Installation Tricky?

Mini-split installations demand meticulous planning and deep technical expertise. 


The crux lies in the line set - the copper tubing that carries refrigerant. This lifeline must be flawlessly brazed, pressure-tested, and evacuated to a deep vacuum (below 500 microns) to remove moisture that could cause acid formation and compressor failure. Our technicians use nitrogen purging during brazing to prevent oxidation inside the lines, and dual-stage vacuum pumps for optimal evacuation.


Another challenge is the variable-length line sets. Improper lengths can lead to oil return issues or insufficient cooling. We use advanced sizing calculators to determine the exact line length and refrigerant charge for each installation. 


Furthermore, mini-splits require precision drilling through exterior walls for line set passage. Our team uses advanced core bits and quality sealants to perform weathertight, aesthetically pleasing penetrations. We use vacuum pumps and micron gauges for accurate refrigerant leak detection.

Why Install Ductless Mini Splits Unit?

Zonal Control

Each indoor unit has its own inverter-controlled compressor, allowing you to heat or cool only occupied spaces. This eliminates the energy waste of central systems that condition unused rooms.

Efficiency Gains

Our mini-splits boast Seasonal Energy Efficiency Ratios (SEER) up to 33 and Heating Seasonal Performance Factors (HSPF) up to 14, far surpassing the 13 SEER and 7.7 HSPF minimum standards. This translates to substantial energy savings.

No Duct Losses

ENERGY STAR estimates that leaky ducts can reduce efficiency by 20-30%. Ductless systems eliminate this loss entirely. Plus, no ducts mean no haven for dust, mold, or allergens.

Heat Pump Advantage

As opposed to gas furnaces, our mini-splits can extract heat from outside air even in sub-zero temperatures, thanks to advanced compressor technology and refrigerants like R-410A.

Whisper-Quiet Operation

Our indoor units operate as low as 19 decibels - quieter than a whispered conversation. This is achieved through noise-dampening compressor jackets and large, slow-spinning fans.
