In my local area, the average year round temperature swings from negative twenty-five to ninety degrees.
We surpass the country’s average for rain and snow.
We deal with ice storms, blizzards, torrential downpours, high winds, high humidity and brutal windchill. While I enjoy experiencing four distinctive seasons, there are challenges involved with such severe weather. We rely on the furnace for approximately eight months of the year. The snow barely melts when it’s time to start up the air conditioner. Our heating and cooling costs account for more than fifty percent of the household energy expenses. In an effort to save money, I’ve made an effort to tighten up the thermal envelope. I’ve invested into Energy Star rated exterior doors and windows, insulation for the attic and ceiling fans. I’ve caulked, weatherstripped and added thermal lined curtains. While I’ve managed to prevent leaks and drafts, I’ve also eliminated essential natural ventilation. Without any influx of outside air, the indoor environment becomes stale. Contaminants such as dust, dander, pollen, bacteria and VOCs become trapped inside and forever circulated by the heating and cooling system. These pollutants create unpleasant odors and cause health concerns. Headaches, sneezing, coughing, difficulty sleeping and irritated issues of allergies can all be blamed on poor indoor air quality. I researched different types of indoor air quality accessories and chose a heat recovery ventilator. The unit is installed right into the existing heating/cooling system and works to bring in a steady supply of fresh air without energy waste. The system uses the outgoing air to preheat incoming air during the winter. In the summer the HRV works to expel excess humidity. My family enjoys better comfort and a healthier home all year round.
