    Newbie question...

    I'm already intimidated by your replies lol

    Here goes, short and sweet...

    I live in a small 3 story home in Montreal Canada ( oil furnace/heatpump). Airflow is not that great in the house, esp upstairs (small ducting etc..). Output capacity on my current oil furnace blower is around 900 CFM (In 'ON' mode all year long). This provides a fairly decent flow of air to keep things moving in all seasons.

    Now, It's time for an electric furnace/heatpump conversion. I was quoted for a GE connect combo. Heat pump and handler are both variable. Max CFM on the blower is around 1000.

    Here's my concern....

    With the handler blower being variable, I fear that the airflow in my house will be compromised. A 'throttling down' blower with a mind of it's own may not be a good solution for my house. I would rather a constant flow of hefty circulating air, at my direction. The contractor said that I can set a fixed speed on the GE handler blower to let's say 900CFM, but then the heat pump compressor will not modulate/ use it's variable function. He said it's not really a problem, just that the compressor will either turn fully on or off. Maybe I'm seeing a problem where there is none, but to me, less airflow equals more sweat/shivers. Slightly confused.

    Thoughts?

    Don't believe you'll need a constant high air flow, with a comfort unit.

    How many times must one fix something before it is fixed?
