Suburban Furnace 2456A 40,000 BTU (P-40)

UNIT MAKES A BUZZING SOUND WHEN IT IS NOT RUNNING.

It replaced an older furnace and is actually more efficient. Great product

Fan is loud.

I order one of these to replace my old one that quit. It arrived I installed it it sounded like a jet plane and vibrated terribly but heated. I returned it and Amazon replaced it. This one I installed turned it on it was quiet and heated so I turned it off being very happy we had a heater again. That evening when it got chilly I turned it back oh and it made a terrible noise like the fan motor was stuck and it did not heat. I am now leaving for a week so will deal with it when I get back. The worst part is that it is difficult to get the heater in and out of the spot it goes in and there is not compensation for my labor. So what I am saying is if you order one of these be prepared to go through a couple before you get one that runs.

Poor initial quality of the turbine fine appears to be out of round and unbalanced causing noise and vibration. Nobody is sleeping while this is running. To correct the turbine wheel will have to be replaced which is a project since the furnace will have to be uninstalled and partially disassembled to replace the turbine wheel.

Broke after 3 months. I can't find anyone who fixes these, so it looks like I'll be going back to my abusive ex! THANKS SUBURBAN!!!

Works great
