Circulator pump or boiler pump

[Glory Dasilva]

For those in the business, how much does it cost to replace a circulator pump?

@Glory Dasilva I have replaced numerous pumps on buildings I own here in the Berwyn and Cicero area. The most expensive was a $600 replacement. That was a total rip off as the pump costs $90 on supplyhouse.com. I now try to plan these events so that I pay my HVAC tech $85 per hour to replace them. Then it costs $200-250 to do worst case. 

I also have to say that changing a pump is not rocket science. If you have changed an alternator before then you can probably handle changing a circulator pump.
