Heating Service in Stevensville, & Bitterroot Valley, Montana

Need a New Heater Installed or an Old One Repaired? We Can Help!


We offer a wide range of heating solutions, including installation, maintenance, and repair of furnaces, boilers, heat pumps, and geothermal systems. 


When a heater reaches the end of its lifespan, it needs to be replaced entirely. Did you know that modern furnaces can achieve efficiency ratings of up to 98%, compared to older models that might only be 60-70% efficient? Similarly, high-efficiency boilers can reach efficiencies exceeding 90%, compared to older models closer to 80%. 

Our helpful technicians can help you choose a new system that meets your needs and budget. We handle the removal and disposal of your old system according to regulations.


You can also hire us for furnace or boiler tune-ups. Our qualified technicians can quickly identify areas for improvement and fine-tune your system accordingly. Annual servicing can dramatically improve the energy efficiency of your existing appliances. 


Not willing to invest in a new heating system? No problem. While it's true that outdated heating appliances are relentless energy guzzlers. Our professionals can install upgrades like zonal control systems and smart thermostats to prevent unnecessary heating in unused areas.

FREQUENTLY ASKED QUESTIONS

  • What types of heating systems do you service and install?

    We service and install a variety of heating systems including furnaces, boilers, heat pumps, and geothermal units. Each system suits different home sizes, energy needs, and budgets. Furnaces are common for colder climates, while geothermal systems offer high efficiency and sustainability. Our technicians assess your home’s layout, energy preferences, and budget to recommend and install the best system. We also handle repairs, ensuring your existing heating equipment runs safely and efficiently.

  • How can I tell if my heating system needs repair or replacement?

    Frequent breakdowns, rising energy bills, uneven heating, and strange noises often signal repair needs. However, if your system is over 15 years old or repair costs become excessive, replacement might be more cost-effective. We perform thorough inspections to evaluate system health, efficiency, and safety. Our recommendations prioritize long-term comfort and value, helping you avoid costly emergency repairs. Timely replacement also enables upgrades to more energy-efficient models, reducing utility costs and environmental impact.

  • What is the typical lifespan of heating systems?

    Lifespan varies by system type: furnaces generally last 15–20 years, boilers 20–30 years, heat pumps around 10–15 years, and geothermal systems can reach 25–50 years with proper maintenance. Environmental factors and usage also affect longevity. Regular professional maintenance can extend your system’s life and improve efficiency. We provide annual tune-ups to catch small issues before they become costly problems, ensuring your heating system operates reliably and safely throughout its service life.

  • How often should I schedule heating system maintenance?

    Annual maintenance is crucial for safety, efficiency, and longevity. We recommend scheduling tune-ups before the heating season to clean components, check for wear, test controls, and ensure safe operation. Regular maintenance prevents breakdowns, improves air quality, and lowers energy consumption. Our thorough inspections include filter changes, thermostat calibration, and system performance checks. Routine care also helps identify small repairs early, saving money over time and keeping your home comfortable all winter.

  • Do you offer emergency heating repair services?

    Yes, heating failures can happen anytime, especially during Montana’s cold winters. We offer emergency repair services to restore your system quickly and safely. Our technicians are trained to diagnose and fix urgent issues promptly, minimizing discomfort and risk. Whether your furnace stops working or you detect a gas leak, call us immediately. We prioritize emergencies to ensure your home stays warm and safe when you need it most.

  • What are the benefits of upgrading to a high-efficiency heating system?

    Upgrading to a high-efficiency heating system can significantly reduce energy costs and environmental impact. These systems use advanced technology like variable-speed motors and smart thermostats to optimize fuel usage and maintain consistent comfort. High-efficiency units often qualify for rebates and incentives, lowering upfront costs. Over time, energy savings offset installation expenses, while improved performance enhances indoor air quality and home value. We help you choose models that suit your home and budget.

  • Are rebates or incentives available for heating system upgrades?

    Yes, local, state, and federal programs often provide rebates or tax incentives for installing energy-efficient heating systems. These incentives can substantially reduce your upfront costs. Eligibility depends on system type, efficiency ratings, and installation criteria. We keep current with available programs and assist you in completing applications, ensuring you maximize savings. Taking advantage of these incentives makes upgrading more affordable while helping your home become greener and more cost-effective.

  • How do I choose the right heating system for my home?

    Choosing the right system involves considering your home’s size, insulation, existing ductwork, and energy goals. We perform a comprehensive assessment including heat loss calculations and energy usage analysis. We then recommend systems that balance efficiency, comfort, and cost-effectiveness—whether a traditional furnace, heat pump, or geothermal system. Our goal is to provide a solution tailored to your lifestyle and budget, ensuring reliable warmth and lower energy bills year-round.

  • What should I do if my heating system isn’t working properly?

    First, check your thermostat settings and circuit breakers. If those are correct and the system still fails, avoid DIY repairs which can cause further damage. Contact us immediately for a professional diagnosis. Ignoring problems like strange noises, uneven heating, or frequent cycling can lead to costly breakdowns or safety hazards. Our technicians quickly identify issues and recommend repairs or replacements, restoring safe and efficient heating promptly.

  • Do you offer financing options for heating system installations?

    Yes, we understand heating upgrades can be a significant investment, so we offer flexible financing options. These plans allow you to spread costs over time with competitive interest rates and manageable monthly payments. We work with reputable lenders and guide you through the application process, helping you select a plan that fits your budget. Financing enables timely system upgrades without compromising comfort or safety.
