Hi, I posted this message , or so I thought, last week. I forgot to track which board I posted it, if you replied..please do so again because I can't find the right board.

My Landlord was kind enough to install a new , but used, furnace (Byrant)last week. The old one worked fine but he thought the new one would be more efficient in this old farmhouse. It has been installed for about a week now. We notice a MUCH improved volume of forced air in most rooms but the air is cooler than the old furnace. Is there an adjustment that the service tech needs to make? For some odd reason the rooms that were traditionally harder to keep warm are now toasty warm and the rooms that were always warm are now much cooler. The bedrooms are another story, hardly any air coming out, much cooler upstairs than it used to be.
I have called the tech back, have not talked to him directly though. Any thought about what I should make sure he does?

Thanks

He installed a new furnace with old duct work.
What about the fact that in most rooms the volume of air has increased considerable the air is much cooler, does he need to make some adjustments that result in warmer air?

On some furnaces, the fan has wiring controls that allow lower or higher output. Maybe this one has "high" selected, while the old one did not.
Do you notice a difference in noise level?

Yes a HUGE difference on noise level and also in the volume of air generated. As I said, the volume of air seems much improved with the new furnance, its just that the air it generates seems colder.

Thanks, that makes much sense.

By coincidence, LITERALLY while on the phone today with the service tech explaining all this...I smelled a burning smell. It looks like the blower motor has burned out. I currently have NO heat with the outside temp at 19 degrees right now. The service tech is going to stop by this afternoon.

While on the phone the service tech explained that when he installed the new furnace he noticed some duct work that was needed. He fixed a few things in the basement. He claims that the old furnace was mostly heating the basement and some upstairs rooms were being heated via a lot of heat going up the chimney. I am guessing that what he has done is increase the effiency of the heating system but lowered the heat in some important rooms. I do need to get the ducts going to the bedrooms looked at. I also think , as suggested on this bulletin board, that lowering the fan level will increase the heat with overall more satisfactory results. Of course, that all depends on him actually showing up today and fixing the burned out blower motor.

Andy.
