I recently had a new Bryant Hybrid Heat system installed in my Connecticut home. The home is a two story colonial with 1600 sq. ft. The basement is not finished. The indoor equipment was installed in the attic and duct work run through closets to the first floor. The return is located in the second floor hallway, all registers are in the ceilings and the thermostats are located in the living room and upstairs hallway.
The issue is that the second floor gets too hot. Overnight settings are 66F for first floor and 68F for second. When the furnace kicks on in the morning, the second floor temperature gets as high as 80F with all bedroom doors closed. The temperature will reduce to ~75F once the bedroom doors are opened. Second floor temperatures during the day average 72F and can be as high as 75F even with both thermostats set to 70F. Walking down the stairs you can feel the hot air is hugging the first floor ceiling and going straight up the stairs to the return.
My questions are:
1) Is this expected given the registers are in the ceiling?
2) Is there anything that can be done to correct this? The only acceptable way for me to get ductwork to the basement for floor registers is to build a chase outside the house.
3) Will the Evolution control work with using radiant floor heating as the auxiliary source instead of a furnace?
My system includes the following Bryant components:
- 3 ton, 3 stage furnace
- 18 SEER heat pump and evaporator coil
- Evolution zone control, damper control, smart sensor (upstairs)
- Perfect Air Purifier
