Steam heat system suddenly VERY loud:

“About two weeks ago our steam heat radiators started making very loud noises when on. I’m talking REALLY loud. They wake up the whole family when they turn on at night. We’re miserable and need recommendations for someone with experience working on old steam heat systems.

Our rowhouse was built in 1924, and the current boiler was installed by the previous owners in 2007. On 12/15, the boiler wouldn’t start. I called Jiffy plumbing, and they sent out Ron Smith (I mention his name just in case someone can vouch for him). Ron reseated a spring on the pressure switch that had gotten out of place. Once he left, the noise began. Loud banging in the pipes and radiators, and it sounds like there’s a lot of water in the radiators. I called Jiffy back the next day, and they said that Ron did nothing that would cause noise. They are happy to come out and try to determine the problem, but I am wondering if there is someone more qualified. PSI is currently set between 1 and 2. Any help would be greatly appreciated!”
