New Furnace Installation with Expert Guidance
When it’s time to replace your furnace, the choices can feel overwhelming (especially if your old system stopped working unexpectedly). That’s where we come in. Halcro Heating and Cooling will walk you through the selection process, taking into account your home’s layout, insulation, fuel source, and budget.

And because we live here too, we’ll help you find available rebates or financing if you’re looking to make the upgrade more affordable.
Furnace Repair Done Right: No Guesswork, No Upsells
Your furnace might give subtle hints when something’s wrong, or it might stop working without warning. Either way, our team will arrive on time, get straight to work diagnosing the issue, and explain what’s happening in plain language. No scare tactics, no inflated quotes, just clear options and upfront pricing.
We repair all major furnace brands and models, including natural gas, propane, oil and electric systems. From minor sensor issues to major component failures, our experienced technicians come prepared with the tools and parts to get most repairs done the same day.

We commonly fix:
- No heat or blowing cold air
- Thermostat not responding
- Pilot light or ignition failure

We also offer 24/7 emergency service for those nights when the temperature drops fast and the heat won’t kick on.

Frequently Asked Questions (FAQs)
How do I know if my furnace needs to be repaired or replaced?
If your furnace is over 15 years old, needs frequent repairs, or struggles to heat your home evenly, it may be more cost-effective to replace it. We’ll always inspect your system first and explain your options clearly with no pressure, no upselling. In many cases, a straightforward repair is all that’s needed to keep you warm.
What are the signs that my furnace is failing?
Common signs include inconsistent temperatures, strange noises, rising energy bills, frequent cycling, or the furnace simply not turning on. If something doesn’t feel right, it’s best to have us take a look before the problem gets worse.
How often should I service my furnace?
We recommend having your furnace professionally serviced once every year or two, ideally in early fall before you start relying on it daily. Routine maintenance helps prevent surprise breakdowns, improves efficiency, and extends the life of your system.
Why is my furnace blowing cold air?
A furnace blowing cold air could be caused by a dirty air filter, thermostat issue, pilot light problem, or more serious internal damage. We can quickly identify the cause and get your system back on track.
What does a furnace tune-up include?
Our standard tune-up includes a full inspection of safety controls, burner and flame sensor cleaning, filter check, and airflow testing. We make sure your furnace is operating safely and efficiently before the cold really hits.
How long does a furnace typically last?
Most furnaces last around 15-20 years with regular maintenance. If your system is approaching that age, or if repair costs are stacking up, we can help you weigh the pros and cons of replacing it.
What’s the best type of furnace for Montana winters?
High-efficiency gas furnaces are the most popular choice in Great Falls and the surrounding areas due to their power and reliability in subzero conditions. We’ll help you choose the right size and model for your home’s needs and your energy goals.
Is it safe to keep using a noisy furnace?
Unusual banging, rattling, or whining sounds are usually signs of a mechanical issue or loose components and could be a safety risk if ignored. It’s always safer to have a technician inspect the system and address the root cause.
Can I install a furnace myself or should I hire a pro?
Furnace installation involves gas lines, electrical work, sheet metal fabrication, and local permitting so it’s not something we recommend doing yourself. Hiring a licensed technician ensures the job is done safely, up to code, and backed by warranty.
Will a new furnace help lower my energy bills?
Yes, especially if your current unit is more than 10-15 years old. Newer models are more efficient and can reduce heating costs. We install ENERGY STAR®-rated systems designed for long-term savings.
