Welcome! Here are the website rules, as well as some tips for using this forum.
I always had Forces air, until my new home. I read I Got Steam Heat and My head is overwelmed with all kinds of questions and concerns from too much PSI to TRV issues. The former owners had the boiler replaced in 2000, and boiler does get serviced twice a year, but I had them out and they really didn’t provide positive feedback except for me to live with the knocking and close the radiators partially to cool the room..... both answers which I know now isn’t right. I want to get a professional out to look over the boiler and radiators but am afraid of getting another knucklehead. Anyone has a contacts in the Kalamazoo / Battlecreek area of Michigan for me? The closest one from this website is almost 2 hours away.
