I live in the northern area of the country, where the weather is serious just about all year round. In the summer, the temperature often climbs into the nineties, with drastically high humidity levels. During the winter, the people I was with and I live with sub zero temperatures, vicious wind chill, as well as tons of snow. The Springtime as well as fall are constantly frigid as well as damp, so the people I was with and I usually need to run the gas furnace. With either the heating or cooling method running for most of the year, there’s no option of opening the windows. To conserve energy, I’ve tightened up the condo as much as possible. I’ve updated windows, added insulation, caulked as well as weatherstripped. I’ve worked certainly strenuous to eliminate every crack, hole or leak which might allow our heated or cooled air to escape. This has made a immense difference in our daily energy costs as well as greatly improved the comfort of our home, then unfortunately this traps all sorts of contaminants in the house. There’s no influx of fresh air, as well as no option for dust, pollen, dander, or unpleasant smells to escape. There’s concerns with air quality, which can lead to health concerns. After consulting with a local Heating as well as A/C contractor, I invested in a heat salvage ventilation system. The ventilator brings fresh, outside air into the condo as well as extracts the stale, stuffy air. Plus, it uses the outgoing air to preheat the incoming air in the winter. The ventilator also helps to combat excess humidity during the summer time months. Installing the ventilation method has saved myself and others quite a bit of money in energy costs, while also improving the health, cleanliness as well as overall enjoyment of our home.
