* j3 O$ \/ w; ^: h6 i7 o#1. All new houses have two seperate fresh air ducts, but some old houses like mine has one, only for air supply for burner. What I have done to improve the air quality are: Replaced exhaust fan switches with timers in all bathroom and installed exhast fan and air duct if there is no before, the timer can exhaust indoor poor air out evertime a tenant using bathroom; I also installed exhaust duct for cooking hood, so people can exhaust cooking smells out; Changed the thermostat that can set HVAC fan manual on once a while to circulate the air inside the house.)

It maybe too warm for people in room upstairs while keeping comport temperature in basement. I readjusted all HVAC vents to make sure vents are open in basement and close more upstairs. Furthermore, I reduced blower speed to the lowest and according to adjusted the burner flame of the furnace.) A+ F* B9 I. T: Q" s, t) b- e
