What’s Wrong With My Boiler? Here Are Common Issues We Fix
We get calls from homeowners and property managers throughout Great Falls with questions like:
- “Why is my boiler making loud banging sounds?”
- “Why are my radiators cold on one side?”
- “Why does the pressure keep dropping?”
Here are a few of the most common boiler problems we solve:
No heat or hot water
Often caused by valve failures, thermostat issues, or airlocks
Leaking boiler
Can stem from pressure issues, worn seals, or corrosion
Uneven heating
Could indicate air in the system, pump failure, or zone valve problems
Low boiler pressure
A frequent issue in older systems or after bleeding radiators
Radiators not heating
Often tied to sludge buildup, trapped air, or faulty thermostatic valvesosion
Our team will identify the root cause and provide an honest repair plan. If repairs aren’t cost-effective, we’ll recommend the right next steps, including boiler replacement or converting to a furnace system through HVAC System Retrofitting.

Boiler FAQs for Great Falls Homeowners

We recommend annual maintenance, ideally in the fall before peak heating season.
Can I replace my boiler with a furnace instead?
In some cases, yes. We offer system retrofitting and can help you compare the pros and cons of switching.

Yes—we offer light commercial boiler service for offices, storefronts, and multi-unit properties. See our Commercial HVAC page for more info.
