I had an energy audit performed and they recommend attic insulation and sealing, but since the house is too tight, they recommend a fresh air ventilation system.
I am concerned that any energy saving for insulation and sealing will be offset by the increased operation costs for the ventilation.
The contractor also recommends a supply only ventilation system. While the cost is about 1/2 of a heat recovery or energy recovery ventilator I am concerned that it will cause issues since the stale air is not being exhausted and I am curious if there are increased energy costs since the fresh air is being dumped directly into my HVAC.
I live in New Jersey and have forced hot air\central air conditioning. Either ventilation system will be connected directly to the hvac.
Any feedback on the energy costs or the comparison of a supply versus balanced (HRV\ERV) ventilation system ?
