Signs Your Heat Exchanger Needs Immediate Attention

Most heat exchanger failures don’t happen overnight. They build quietly — a little extra noise here, a pressure change there — until one day, the system can’t keep up. The trick is catching those small shifts before they snowball into costly downtime.

  Maybe you’ve noticed the outlet temperature isn’t quite what it used to be, or it swings from hot to cold without warning. Sometimes it’s a subtle pressure drop that forces your pumps to work harder, or a faint leak that you keep meaning to “check later.” Even a strange rattle or whistle from inside the unit can be a warning you can’t afford to ignore.   The problem? Every one of these signs can be easy to brush off in the middle of a busy day. But the longer you wait, the greater the risk of gasket failure, corrosion, or complete system shutdown — and that’s when repair costs multiply.   At Heartland, we’ve seen it all.
