FWIW: I finally solved the problem with the rattling in the duct work. And I’m very glad I didn’t call Sears to have it repaired …as the problem was only marginally related to the new HVAC system.

Turns out one of the ducts had a baffle that was somewhat loose. I had seen the baffle before, but thought it was secure. After hunting around a bit more I determined that the baffle had to be the problem.

After removing the baffle, the rattling noise went away.

As for why the rattling started after the new HVAC system was installed … the best I can figure is that the new system blows more forcefully than the old one did … so it moved the baffle around more.

None the less, the system is much quieter now.

Just found this… it was truly and interesting read for me! I worked for a Carrier contractor for several years and we have considered becoming a part of the Sears program, but heard only horror stories…

It sounds like in the end it all worked out for you. Were they able to get the rattle in the ductwork completed?

Im also curious to hear how your attic vent install went. In most cases, the nut holding the fan blade is so rusted on, replacing the motor requires so much of the unit to be disassembled, your’e almost better off having a pro do the work!

I mentioned the tankless hot water heater to a friend the other day, and he mentioned that Consumer Reports is going to be doing a story on them in a few months.

He also mentioned that there had been a lot of comments on the CR forums about how poorly they work.

Glad to hear the project was mostly a success. Every time I see the tankless hot water heater on a TV improvement show, I think, \”Gee, that seems like a good idea, hot water on demand. Rather than just endlessly letting water heat and cool when it isn\’t needed.\” And then after checking the price, I just stop thinking.
