Boiler Repair, Maintenance & Replacement
A boiler that is short-cycling, leaking, or leaving rooms cold is usually a hydronic system problem, not just a failed part. Colorado Green Plumbing, Heating & Cooling diagnoses and repairs residential boilers for homeowners in Erie, Longmont, and nearby Northern Colorado communities. We also maintain and replace systems when repair no longer makes sense.
Family-owned since 1980 and based in Erie, we work on both the heating equipment and the plumbing side of the system: pumps, zone valves, expansion tanks, piping, radiators, and baseboard.

Residential Boiler Repair
We diagnose the cause before recommending work. Repairs may involve:
- Circulator pumps and zone valves
- Expansion tanks and pressure components
- Ignition, controls, and thermostats
- Hydronic piping and connections
- Radiators, baseboard, or leaking components
If the boiler is near the end of its life, we will say so and walk through replacement instead of stacking repairs.
Maintenance
A pre-season service visit checks the boiler and related components for your system type. That is the best time to catch a weak pump, a failed expansion tank, or a control issue before the first hard freeze. We explain what we find before any extra work.
Replacement and installation
Replacement is about the home, not a like-for-like swap. Piping layout, zones, radiators or radiant loops, and load all affect the right size and type. Newer boilers can improve efficiency and controls, but only if the installation matches the system. We recommend equipment that fits the house, not the largest unit on the truck.
We had them replace a sewer line from in the house out through the yard. You'd never be able to tell they were there. The crew was very respectful, worked fast, and ran the sewer line at the end to make sure all was well. They told us everything going on, walked us through what they were doing and why. Very impressed and would highly recommend them for large projects. The price was also unbeatable.

I had problems with my water heater and the owner and his crew were there right away. They put down tarps and we're extremely respectful of our house. CGP's prices were very reasonable, too. I will definitely be using Colorado Green Plumbing in the future.

Decided to call Colorado Green based on all the positive feedback. Couldn't be more please with this company! David was here on time, put my gas line in for my stove and fixed my leaky sink(that happened just this morning). Thank you David!! They are friendly, easy to talk to, explain and show the work they've done...it's amazing! We will call you again for our kitchen remodel :)

FAQ
Do you repair boilers, or only replace them?
Both. We repair circulators, zone valves, expansion tanks, controls, ignition parts, and related piping when that is the practical fix. We recommend replacement when the boiler is failing often or repair cost no longer makes sense.
What boiler brands do you service?
We service most residential gas and hydronic boilers found in Northern Colorado homes, including systems tied to baseboard, radiators, and radiant heat. Call with the brand and model if you want confirmation before the visit.
Why is my boiler making banging or gurgling noises?
Common causes include air in the system, a failing circulator, mineral buildup, or pressure problems. The noise alone does not tell you which one. A technician needs to check the boiler and the loop.
How often should a boiler be serviced?
Once a year, ideally before heating season. Annual service is the most useful time to catch a weak component before the system is running every day.
Can a boiler problem be a plumbing issue?
Yes. Hydronic heat uses pumps, valves, expansion tanks, and piping. A cold zone is often circulation or a zone valve, not the boiler itself. Our techs cover both sides of that system.
How soon can you get here?
Same-day appointments are available when the schedule allows. Call 303-772-1318 for the soonest opening.
What areas do you serve?
We serve the northern front range and north of I-70's for Boiler work.
