It's 95 F outside,but sweating bullets cooking at 78 inside, yet I have the AC set for 73.
Problem seems to be air flow to upstairs with the new HE Carrier furnace.
The basement is super cool even with the vents closed. Last year with the old furnace I could just run the fan most days and move the air and it would cool down well even without the ac on.
I took the fresh MERV 8 filter out to see if the pressure to upstairs improves.
Also have floor baseboard return air vents through out upper two levels no RA in basement.
I haven't adjusted or made any damper changes since the new system was installed and the heat distribution was excellent. In fact I have taped and sealed ducts and boots to improve the flow. Do I need to do anything to tweak the AC distribution.? Should I fully open all heat vents to improve circulation?
Air is blowing cold, feels fine at the vents, just not getting high enough.
I have also improved attic and rooftop ventilation so the attic should actually be cooler than last year. So why is it so hot?:furious:
