New furnace: is it too good?
We are redoing our lower level and hoped to do the right thing by getting a tankless water heater, new windows, insulation and energy efficient furnace & comfortnet thermostats.
Our home is on 2 levels, 1050 sq ft up and additional 500 sq ft living space below so we have it zoned. Our contractor told us to buy a 60K BTU furnace; we opted for 96% AFUE with two stage with variable blower; Goodman GMVC960603BN.
We get high winds from the vents; we thought that the variable blower & two stages meant that the unit would operate on a low flame and low fan (cfm) level but that doesn’t seem to be the case, the furnace starts out slow then ramps up to gale storm.
Is this thing installed correctly? Is it too big? Is there a setting we can adjust?
Our general contractors put this in, but there is only one that I can speak with because of language barriers.
