Upgrading to a Hybrid Gas-Electric Forced Air System: A Case Study in Bozeman, MT
As homeowners approach retirement, priorities often shift towards comfort, efficiency, and sustainability. This was the case for Corky and Lois J. of Bozeman, Montana, who opted to downsize while enhancing their heating system. This article examines their transition to a more efficient and environmentally friendly hybrid gas-electric forced air system, outlining the challenges faced, solutions implemented, and advantages gained from this innovative HVAC upgrade.
Understanding the Need for Change
Corky and Lois moved from a traditional natural gas forced air system that offered basic air conditioning to a more advanced dual fuel electric/gas heating solution. Given Bozeman’s variable and often extreme winter temperatures, they sought a system that would not only maintain warmth but also maximize energy efficiency. Their aims were clear: to enhance indoor air quality, lower energy expenses, and adopt environmentally responsible heating methods.
The Challenges of Heating in Bozeman
The climate in Bozeman presents particular challenges for homeowners. With extended periods of low outdoor temperatures, effective heating solutions that maintain efficiency are essential. Additionally, escalating energy costs exacerbate the situation. Corky and Lois aimed to optimize the efficiency of an electric heat pump while ensuring dependable performance during the coldest months.
The Solution: A Custom Hybrid System
To address these challenges, Mountain Heating and Cooling developed a hybrid gas-electric forced air system specifically designed to meet the needs of Corky and Lois. Central to this upgrade was the Trane S9V2B080U4SBA furnace, recognized for its multiple stages and variable speed fan, which provides quiet, high-efficiency heating even under extreme cold conditions.
This furnace was complemented by a Mitsubishi IntelliHeat PAA-A36BA1 dual fuel coil and a Mitsubishi Hyper Heat PUZ-AK36NLHZ condenser. This configuration enables optimal heat pump operation during milder weather, seamlessly transitioning to gas heat as outdoor temperatures drop. The installation also included a Trane CleanEffects air purifier, a Fantech HERO 150H heat recovery ventilator, and a Navien NPE0240 tankless water heater, which collectively enhance overall comfort and indoor air quality.
The project was completed efficiently within a two-week timeframe, commencing on December 15, 2025, and concluding on December 30, 2025.
The Benefits of the Hybrid System
The upgraded system provides an array of benefits:
- High Efficiency: The Trane S9V2 furnace achieves an impressive 97% efficiency, significantly lowering energy consumption and operational costs.
- Reduced Noise: The variable speed fan ensures a quieter indoor ambiance without compromising performance.
- Improved Indoor Air Quality: The integration of air purification and ventilation systems minimizes airborne allergens and guarantees a continuous influx of fresh air.
- Long-Term Reliability: Homeowners benefit from manufacturer-backed warranties, including 10 years on parts and labor for the Trane furnace and air purifier, and 12 years on the Mitsubishi heat pump.
- Sustainable Choices: The employment of Mitsubishi’s R454B refrigerant aligns the system with environmental objectives, promoting responsible energy use amid rising energy costs.
Conclusion: A Successful HVAC Upgrade
Corey Johnson, President of Mountain Heating and Cooling, reflects on the successful completion of this installation, highlighting the efficacy of hybrid systems in the Montana climate. This upgrade not only satisfies Corky and Lois’s immediate heating requirements but also positions them as conscientious stewards of their energy resources as they transition into retirement.
