House name correction is very important when your house number is not right, which means it has totals of 4, 8 and 9. Including Vastu, we have seen that houses with perfect vastu give bad results to the family members when the house numbers aren't right. Since it is not so easy to correct the house numbers because of registration process, the alternate is giving house a harmonic name as per all family members, to avoid the problems as a result of bad house numbers.
