we are thinking of retrofitting a HRV system into existing forced air furnace. Can you pros suggest any tips make models do's donts and cost involved?
HRV systems are designed to be run in sealed homes, generally with their own duct work to remove stale air and replace it with fresh clean pre-conditioned air and in most cases if your home was built to be able to take advantage of any benefit of running an HRV it would already be in place.
Now unless you just gutted the whole house and installed new insulation and V. barrier, caulked your sill gaskets and added gaskets to the utility boxes on your exterior walls and replaced all your windows and doors the addition of an HRV system to your home is a waste of money.
