Hi, I'm a homeowner who doesn't know about heating systems so I may be in the wrong place. If so, just let me know. I live in a fairly small town and am not sure how to get good, objective advice. Just had a new Weil-McClean boiler installed by a long-time company in the area with a decent reputation. I didn't go with the highest bidder and now think something's fishy about how these guys answered my questions about what was needed and how they did the job. The contractor has been out 5 times to fix banging, rattling, tapping noises. He keeps saying that the oil has to be skimmed off of the water and it's just what happens with a new boiler, which I've read about. But he tried a chemical cleaner 3 times that didn't work. Then he got a different kind that he said works better. Nope. The last time he brought another guy who fixed some broken traps on pipes and said the next thing to try if it doesn't work is raising the radiator because the floor is sloped. It's a little better but still not right. The killer is that it makes the most noise in the middle of the night.
I don't have a lot of extra money lying around and plan on selling this house in about 2-3 years (hoping to retire someday) so am not looking to sink a lot more money into this. Obviously, I need the noises fixed (I also have a tenant upstairs) but am trying to figure out the best solution, given these considerations.
Should I just keep dealing with these guys or is it obvious that they'll never make it right, or can they even make matters worse?
I took some pictures but am not sure if they are helpful.
