I had to use Cordone & Tonucci because they were contracted out to replace the boiler in my condo/apartment building. My tenants had complained that the heat wasn't working so Cordone &Tonucci came to check it out. Fortunately, it wasn't anything big, just needed to replace the battery in the thermostat. Unfortunately, they charged me an hour and a half labor for what took 5 minutes!!!! I don't know how Cordone & Tonucci can still be in business with their shady ethics. This company should be ashamed of themselves for taking advantage of good people.
