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