Boiler & Radiant Heat in Longmont, Colorado

Knocking usually means trapped air, water hammer from a stuck valve, or in steam systems a pitch problem letting condensate collect. Bleeding is the first step; persistent knocking is a diagnostic visit.

Most residential hydronic systems sit in a low static band when cold and rise modestly when hot — check the manufacturer's plate for your unit. Pressure that keeps climbing usually points to a failed expansion tank or a leaking fill valve.

It varies by state and by the credential involved. Hydronic and steam boilers are commonly plumbing-licensed work; forced-air is HVAC. Confirm the contractor holds the right credential for boiler work in your state.

Permit requirements around Longmont are set locally rather than statewide. As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
