At our last AC service I asked what speed the air handler's fan was set to and they told me "Medium."
They'd moved it down from "High" when they installed our spiffy new non-leaking ducts and the main bedroom has had abysmal air flow ever since.
This has pissed us off since the install because, despite dumping half the cooled air into the attic, the bedroom was never uncomfortable with the old duct work. Even with the door closed
The manager/owner's only suggestion was to leave the door open or to get an additional air return installed in the bedroom.
I don't see where they'd put it, and I'm not rearranging the stuff I have against the walls to suit this additional charge to fix what I feel they broke.
In the meantime, I have baby gates over the bedroom door to keep Beeper and Shadow separated.
I've also had a fan on the floor blowing into the bedroom, hoping to pull the correct temperature air from the rest of the house into the bedroom. Which does work, but the bedroom is always closer to the outside temp than the rest of the house. Usually warmer.
Today, thinking about that air return idea, I turned the fan around.
That little extra flow out of the room has really helped air come out of the duct and keep it at the proper temp. Though I fretted a but because that triggered the AC to run more often for a little while as things in the bedroom shed heat.
Eyes crossed that this will work.

They have air duct fans that kick on when there's airflow to boost the flow into a room. They can look like the regular air duct grills. Also, there are fans that sit in the air duct itself (just extend the flexible duct with the solid fan, and insulate it. I'd want to add a control, since those usually just have standard AC plugs and run constantly. You can add a grill in the door -- common in commercial buildings, especially in equipment rooms.
ReplyDeleteI saw those duct fans that are activated by flow and can't find one that matches my register size. Still looking.
DeleteThe kludge we have is working, and I've got door-vents in my wishlist at Amazon... Stalling, I guess.
