yes the calculators can go by sq foot or average home size base on 3-4 bdr etc. for getting an idea on size of HRV needed, mine was for a standard 3 bdrm home. although i got the size up. Got it through Coral in Kelowna. saved $1500 installing myself. Didnt go for the grants, didnt get the inspections before and after, seemed not much left after. We were in a rush to save the home from damage.
