I’ve done everything I can recognize of to trim heating plus cooling costs. I’ve gradually updated to Energy Star rated windows plus exterior doors. I’ve added caulk, weatherstripping, insulated drapes plus a ton of insulation in the walls, ceilings plus attic. I’ve made every effort to prevent my heated plus cooled air from escaping outside. While these improvements lowered my energy costs, my tightly sealed home 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 oil furnace plus cooling system. It also traps indoor contaminants plus can lead to unpleasant plus unhealthy conditions. Pollutants such as dust, dander, mold spores, odors plus bacteria are continually recycled by the oil furnace plus cooling system. The home doesn’t smell or recognize as nice, plus the health of my family is put at risk. After a little bit of research, I l received that reasonable ventilation is a requirement for familiar indoor air quality. There’s rarely a time when I can open a window plus welcome in fresh air, so I invested into a ventilation system. The ventilator is tucked out of sight, completely silent, plus requires only annual upkeep. It works 24/7, brining in fresh, outdoor air plus expelling stale, indoor air. In the warm season months, this process combats humidity plus reduces strain on the cooling system. The home feels more comfortable at a higher temperature. During the Winter, the ventilator undoubtedly uses the moderate outgoing air to preheat the incoming air.
