Reliable Furnace Upgrades and New Installs Across Western Montana
Montana winters don’t cut corners—and neither do we. When it’s time to replace or install a furnace, you need a system built to handle the kind of cold we get in the Garden City area. Garden City Plumbing & Heating has been installing furnaces in Missoula and Western Montana homes since 1985. Our team knows what works here, how to size systems for local construction styles, and how to get the install done right the first time.
We install new furnaces for homes under construction, replace aging or broken units, and help homeowners upgrade to more efficient heating that pays off over time.
What Type of Furnace Do You Need?
We install a wide range of high-efficiency gas and electric furnaces built to withstand Montana winters. Whether you’re focused on performance, energy savings, or both, we’ll explain your options in plain terms.
Systems we install include:
Standard and high-efficiency gas furnaces
Variable-speed and two-stage furnaces
Electric furnaces for homes without gas service
Zoned heating systems
Compatible smart thermostat controls
Heat pump + furnace hybrid systems (dual-fuel)
Not sure what you need? We’ll break it down by what matters most: comfort, reliability, and cost of ownership—not just the sticker price.

When to Replace Your Furnace
Some signs are obvious—like no heat or constant repairs. Others are subtle, but just as important. We help homeowners identify when a furnace has reached the end of its lifespan and guide them through a smart replacement.
Here are some of the most common indicators:
- The furnace is 15–20 years old
- You’ve noticed rising energy bills despite normal usage
- It struggles to heat evenly or keep up in colder months
- You hear loud, strange noises during operation
- The system cycles on and off frequently
- You’ve had multiple service calls in the last year
If you’re not sure, we’ll assess your current system and give you honest feedback on whether a repair makes sense—or if it’s smarter to replace it now and avoid the risk later.
Our Furnace Installation Process
We know replacing a furnace isn’t something you do often, so we make the process as clear and low-stress as possible. Here’s what it looks like when you work with our team:
1 – Home evaluation
Before we talk systems or pricing, we take the time to understand your home. That means looking at your current setup, walking through your layout, and asking the right questions about how your home heats — and where it doesn’t. Our goal is to solve real problems, not just swap boxes.
2 – System sizing and selection
Bigger doesn’t mean better. We run the numbers to figure out exactly what size furnace your home needs — based on square footage, insulation, window exposure, and more. Then we walk you through options that fit your comfort goals and budget. We’ll explain why one model might work better than another and help you decide without pressure.
3 – Transparent estimate
Once we know what’s right for your home, we put together a clear quote that spells everything out — equipment, installation, labor, and any updates needed for ductwork or wiring. No surprises. We’ll also go over financing options or rebates if they apply.
4 – Clean, code-compliant installation
On installation day, we show up on time, remove your old system, and get to work installing your new furnace the right way. We follow all code requirements, double-check every connection, and test the system fully before we consider the job done. And yes — we clean up after ourselves.
5 – Walkthrough and support
Before we leave, we’ll walk you through how your new furnace works, how to use your thermostat, and what to expect during the first few heating cycles. We’re happy to answer questions, and if anything comes up after the install, we’re just a phone call away.
We handle everything—from permit coordination to system testing—so you don’t have to worry about a thing.
