HVAC Retrofitting
HVAC System Retrofitting in Great Falls, MT | Upgrade Efficiency
Upgrade Your Comfort Without Starting from Scratch
Not every heating or cooling system needs to be replaced to perform better. At Northern Heating & Cooling, we offer professional
HVAC retrofitting in Great Falls—upgrading the efficiency, performance, and reliability of your existing system without the cost of a full replacement. Whether you're in a century-old Central Avenue home or an aging shop space on the west end, we tailor retrofits that make your system work smarter, not harder.
Bring New Life to Your HVAC System
HVAC retrofitting means modifying an existing heating or cooling system to meet today’s performance standards. It’s a smart, cost-effective way to improve energy efficiency and comfort—especially in older homes or buildings not designed with modern HVAC needs in mind. Instead of tearing out your entire system, we help you build on what you already have with upgrades that reduce waste and improve functionality.
Our HVAC Retrofit Services
Every home is different, and so is every retrofit. Our technicians evaluate your current system and recommend targeted improvements such as:
- Installing
high-efficiency burners or blower motors in aging furnaces
- Adding
AC coils to existing heating systems that don’t yet cool
- Converting
electric heat to gas for better energy savings
- Retrofitting with
Wi-Fi thermostats or smart HVAC controls
- Upgrading insulation on ductwork and sealing leaks
- Adding
zoned heating and cooling with new dampers and controls
- Integrating
ductless mini-splits or supplemental systems in tough-to-heat spaces
We also help with older homes that lack ductwork entirely—see our Custom Ductwork or Mini-Split pages for creative retrofit options.

HVAC Retrofit FAQs
Is it better to retrofit or replace an old HVAC system?
It depends on the system’s age, condition, and performance. If the core components are still sound, retrofitting can extend their life and improve efficiency at a lower cost.
Can historic homes be retrofitted with modern HVAC
Yes—retrofitting is often ideal for historic homes where major demolition isn't an option. We design ductwork and zoning solutions to preserve structure and aesthetics
What retrofits deliver the biggest energy savings?
High-efficiency motors, sealed ductwork, and smart thermostats typically offer the most noticeable gains in energy efficiency.
Can you add AC to a home that only has a furnace?
Yes—we can retrofit existing furnaces with AC coils and install condensers outside to add cooling without changing the heat source.
How long does an HVAC retrofit take?
Most projects are completed within 1–3 days, depending on the scope. We’ll give you a clear schedule and walk you through every step.
