When do I change my system?

I’ve done everything I can know of to trim heating & cooling costs.  I’ve gradually replaced to Energy Star rated windows & exterior doors.  I’ve added caulk, weatherstripping, insulated drapes & a ton of insulation in the walls, ceilings & attic.  I’ve made every effort to prevent our heated & cooled air from escaping outside. While these improvements lowered our utility bills, our tightly sealed lake condo also kept fresh air from coming inside.  Since I live in the northeast, where the temperature is either far too high or ungodly low, this helps to lessen the workload of the gas furnace & a/c. It also traps indoor contaminants & can lead to unpleasant & unhealthy conditions.  Pollutants such as dust, dander, mold spores, smells & bacteria are continually recycled by the gas furnace & a/c. The condo doesn’t smell or assume as nice, & the health of our family is put at risk. After a little bit of research, I l received that reasonable ventilation is a requirement for regular indoor air pollen levels.  There’s rarely a time when I can open a window & welcome in fresh air, so I invested into a ventilation system. The ventilator is tucked out of sight, completely silent, & requires only annual upkeep. It works 24/7, brining in fresh, outdoor air & expelling stale, indoor air. In the Summer weeks, this process combats humidity & reduces strain on the cooling system.  The lake condo feels more comfortable at a higher temperature. During the winter, the ventilator absolutely uses the sizzling outgoing air to preheat the incoming air.
