My heat exchangers have a long squirrel cage fan on the back that is VERY noisy. Part of the problem is that it makes the whole unit jump up and down. I have ripped all the surrounding shelving apart and added some rubber under and around the units but they still rattle (and are a pain to pull out). I would just rather get some new ones that won't rattle for a few years... If there is an easy way to fix these then I am for it... Can I just clamp off the hoses going in to the heat exchangers so they don't leak everywhere?
